I’ve noticed that in the LGF debate over climate change, there are certain talking points and memes that keep being brought up over and over. In my attempts to find a way between the exaggerated alarmism of many on the pro-AGW side and the deliberate obfuscation of many on the anti-AGW side, one of the valuable resources I discovered is at ScienceBlogs: How to Talk to a Climate Sceptic.

It’s an exhaustive list of detailed scientific answers to many common anti-global warming arguments constantly posted on the internet (and which often appear in LGF threads on the subject).

UPDATE at 8/9/09 11:23:24 am:

On a related topic, here’s an interesting website: Republicans for Environmental Protection.

It's the Sun, Stupid:

Objection:

The sun is the source of all the warmth on earth. Any increase in temperature is most likely due to changes in solar radiation.

Answer:

It's very true that the earth is warmed, for all practical purposes, entirely by solar radiation. So if the temperature is going up or down a reasonable place to find the cause would be the sun. Well, it turns out that it is more complicated than one might think to detect and measure changes in the amount or type of sunshine reaching the earth. Detectors on the ground are too susceptible to all kinds of interference from the atmosphere. After all, one good cloud passing overhead can cause an instant shiver on an otherwise beautiful, warm day, but not because the sun itself changed. The best way to detect changes in the actual output of the sun versus changes in the radiation reaching the earth's surface because of clouds, smoke, dust or pollution is by taking readings from space.

This is a job for satellites. According to PMOD at the World Radiation Center there has been no increase in solar irradiance since at least 1978 when satellite observations began. This means that for the last thirty years, while the temperature has been rising fastest, the sun has shown no trend.

There has been work done on reconstructing the solar irradiance record over the last century before satellites were available. According to the Max Plank Institute where this work is being done, there has been no increase in solar irradiance since around 1940. This reconstruction does show an increase in the first part of the 20th century that coincides with the warming from around 1900 til the 1940's. This trend in irradiance is not enough to explain it all, but it is responsible for a large portion of that trend in temperature. See this chart of the observed temperature, the modelled temperature and the variations in the major forcings that contributed to 20th century climate.

re: #2 anotherindyfilmguy

At one time, glaciers - hundreds, even thousands of feet high - were as far south as Dayton, OH. It seems that the Earth has been warming for millions of years, with only relatively brief respites of cooling in between.

To predict what the weather is going to be like in the next thousand years, or even hundred years based upon questionable historical temperature data from the last 7 or 8 decades, is exactly like predicting what the stock market will do in the next 100 years based upon the morning's trading session.

I'm not sure what we mean by silly catch-phrases like "climate change" or "global warming," but it's pretty clear that, in the aggregate, anthropogenic global warming is a complete farce. That is, a farce in as much that the current state of science on the matter can make no such claim.

re: #12 Racer X

Here's a comment from the site that's worth repeating:

When you hear arguments like "it's cold outside right now therefore global warming's a LIIEEE", if you are at all familiar with the basic science, at least four inaccuracies in that statement should jump out right away. Pointing out those problems does not mean that the science is flimsy -- merely that it is being attacked (in this case by incompetent non-scientists). Pointing out what science *really* says (something that anyone with scientific training can deduce, but not everyone has this training) isn't indoctrination, it's just swatting down a straw man.

Exactly the same thing happens with evolution: People who don't understand the simple mechanisms of the theory strike out at their straw-man version of it. This doesn't mean evolution's a theory in crisis, or that the science isn't settled - merely that there's a manufactured public controversy that better science education can (hopefully) address.

The question is not whether the climate is changing. The question is whether the climate is changing due to something that people are doing or whether it is a natural flow of events that humans have nothing to do with. Looks like some people are trying to exploit the climate change for furthering their political agenda.

Also referenced in How to Talk to a Climate Skeptic's comments:
The Dunning-Kruger Effect

The Dunning-Kruger effect is an example of cognitive bias in which "...people reach erroneous conclusions and make unfortunate choices but their incompetence robs them of the metacognitive ability to realize it". They therefore suffer an illusory superiority, rating their own ability as above average. This leads to a perverse result where people with less competence will rate their ability more highly than people with relatively more competence. It also explains why competence may weaken the projection of confidence because competent individuals falsely assume others are of equivalent understanding. "Thus, the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others.[Link: en.wikipedia.org...]

32 blangwort  Sun, Aug 9, 2009 10:46:16am

I'm not a Global Warming skeptic, but I do think that the Global Warming theory advocates don't know nearly as much as they think they do.

Read the book The Future of Everything by Dr. David Orrel. This is an extensive treatment of the science of modeling, what the theories of physics really are, where chaotic systems fit in, and how the current climate models work.

I think that people who stand up in front of crowds claiming much of ANY long term climate prediction is full of beans. The most we can say is that the earth probably is warming. Beyond that, we truly don't know.

33 Randall Gross  Sun, Aug 9, 2009 10:46:51am

re: #2 anotherindyfilmguy

There are several engines for warming - they start with the sun, include heat from the earth's core, and heat from chemical and biological processes all over the planet. The models try to account for all of these heat sources as best they can. They are not perfect.
The point of the theory is that if we increase the atmosphere's greenhouse gas to much then we adjust the thermstat of the planet. Not enough heat escapes and we warm more than we would like.

Down in the previous thread someone said something very humorous -- something to the effect that "things were much warmer 200 MYA and things were hunky dory"

Well if you consider insects the size of dogs and crocodiles in Northern Canada "hunky dory" then you need a cluebatting.

Looks like some people are trying to exploit the climate change for furthering their political agenda.

Part of science is searching for just that sort of answer. Science has looked into all the variables that effect climate and the man made increase in CO2 is the only variable that has changed dramatically since the industrial revolution. Since we know CO2 has gone up, and we know it's a greenhouse gas, it's pretty much a slam dunk. Add to that, the fact that CO2 levels track the increase so closely, and it makes a stronger case.

I think it would be foolish to not admit some are using science to push a political agenda, but the science itself isn't pushing one- the data isn't partisan.

41 Pianobuff  Sun, Aug 9, 2009 10:48:10am

What is the correct term for a person that

- Accepts that there has been an average warming trend over recent decades.
- Accepts that CO2 levels have some amount of upward influence on temperature.
- Accepts that Co2 levels have increased for man-made reasons.

but

- Doesn't view computer modeling/simulation as classical science in its current form and is therefore still unmoved by the OMG kind of predictions.
- Believes that science has not yet run its course in determining the extent/impact of man-made causes.
- Is so overwhelmed by the politicization and demagoguery that there is skepticism if anyone claiming to have "the real truth".
- Believes that there is a high degree of common purpose between AGW supporters and energy independence supporters and is frustrated that the two camps can't just agree to do some "right things" even if they disagree on why they would be doing them.

Is that a denier, alarmist, skeptic, or something else... or does it depend on who I ask.

42 Desert Dog  Sun, Aug 9, 2009 10:48:11am

There is no doubt human beings have an effect on the planet. The degree to which they do is still not sufficiently measured by science. This guy is quite arrogant and condescending in his delivery as well. "Mr. Know it All and the rest of you are stupid". My main problem with the radical proponents of AGW is not that they feel human activity is causing problems, it's their solutions to those problems. I reject the Kyoto Treaty as severely flawed.

Avanti sent this link to me one night when I dared challenge the gospel. This guy is smart and explains things in terms so that many who did not understand what the science says can get a better idea of what is being done in the area of research these days. Fair enough there.

Science is not my forte. Political stuff is one of my passions. The USA should never sign a treaty along the lines of Kyoto and for this guy to simply dismiss anyone who objects to it as being naive or stupid tells me a lot about his motivations. With Obama in, we might just open up our society to the jurisdiction of the UN and other world bodies, many of whom are hardly friendly to the USA. We rejected the treaty and used our own laws and motivations to curb our output of the evil gasses. And, we have reduced our numbers more efficiently than the Europeans who did adopt Kyoto. And, let's not forget about the largest polluter in the world, China. India is not far behind. This is where people like the author of this link lose me.

43 JarHeadLifer  Sun, Aug 9, 2009 10:48:24am

re: #21 avanti

No not ding, just show me a link with the data that proves that.

Conversely, show me the "proof" with respect to AGW. When scientists use words like "consensus", it's a time to be skeptical. At one period in history, it was the "scientific consensus" that black people evolved separately from white people, and that white people evolved from a "more beautiful" being located in the Caucasus mountain range. How did that "scientific consensus" hold up over time?

When scientists, who are financed, supported and motivated by political groups, begin to shout down their critics, it's also time to be skeptical - which something that the "believers" in AGW seemed to have checked at the door - their ability to be skeptical.

I would also like to remind people - a lot of this global warming prediction stuff is based on computer models. I was a software developer for over 30 years. I promise you, anything that pretends to predict climate decades out is LOADED with untenable assumptions. They have to be as that is the nature of the beast.

And if you know the first thing about geology and the geologic record, there was a lot of climate change long before man became industrialized.

45 Simple Voice  Sun, Aug 9, 2009 10:48:38am

Interesting website.

On the issue of consensus, I think Michael Crichton said it best when he addressed the California Institute of Technology on January 17, 2003.

This is what he had to say about consensus...

I want to pause here and talk about this notion of consensus, and the rise of what has been called consensus science. I regard consensus science as an extremely pernicious development that ought to be stopped cold in its tracks. Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled. Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you're being had.

Let's be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.

There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period.

I found this tidbit interesting when poking around wikipedia the other day, on the entry about pollster Frank Luntz...

Although Luntz later tried to distance himself from the Bush administration policy, it was his idea that administration communications reframe "global warming" as "climate change" since "climate change" was thought to sound less severe. Luntz has since said that he is not responsible for what the administration has done since that time. Though he now believes humans have contributed to global warming, he maintains that the science was in fact incomplete, and his recommendation sound, at the time he made it.

As always with wikipedia, some amount of discretion is in order. The citation is to an article and transcript for a BBC program. Taken at face value though it appears that the change in language from 'global warming' to 'climate change' was an initiative by the skeptic side instead of the proponents of AGW that are commonly attributed with that development.

I only skimmed the link for this article, so I don't know if that one is mentioned in the list or not, but I found it interesting.

Climate Momentum Shifting: Prominent Scientists Reverse Belief in Man-made Global Warming - Now Skeptics

...Many former believers in catastrophic man-made global warming have recently reversed themselves and are now climate skeptics. The names included below are just a sampling of the prominent scientists who have spoken out recently to oppose former Vice President Al Gore, the United Nations, and the media driven “consensus” on man-made global warming.

The list below is just the tip of the iceberg. A more detailed and comprehensive sampling of scientists who have only recently spoken out against climate hysteria will be forthcoming in a soon to be released U.S. Senate report. Please stay tuned to this website, as this new government report is set to redefine the current climate debate.

In the meantime, please review the list of scientists below and ask yourself why the media is missing one of the biggest stories in climate of 2007. Feel free to distribute the partial list of scientists who recently converted to skeptics to your local schools and universities. The voices of rank and file scientists opposing climate doomsayers can serve as a counter to the alarmism that children are being exposed to on a daily basis. (See Washington Post April 16, 2007 article about kids fearing of a “climactic Armageddon” )

The media's climate fear factor seemingly grows louder even as the latest science grows less and less alarming by the day. (See Der Spiegel May 7, 2007 article: Not the End of the World as We Know It ) It is also worth noting that the proponents of climate fears are increasingly attempting to suppress dissent by skeptics. (See UPI May 10, 2007 article: U.N. official says it's 'completely immoral' to doubt global warming fears )

The United States and the Environment: Laggard or Leader?

To borrow the blunt language of Generation X and the "Millennials," does the United States suck when it comes to the environment? Contrary to the perception expressed in the epigraphs above, the answer turns out to be a resounding No; the United States remains the world's environmental leader and is likely to continue as such. But to paraphrase the old slogan of the propagandist, if a misperception is repeated long enough, it will become an unshakeable belief.

Environmental improvement in the United States has been substantial and dramatic almost across the board, as my annual Index of Leading Environmental Indicators and other books and reports like it have shown for more than a decade.[3] The chief drivers of this improvement are economic growth, constantly increasing resource efficiency, innovation in pollution control technology, and the deepening of environmental values among the American public that have translated into changed behavior and consumer preferences. Government regulation has played a vital role to be sure, but in the grand scheme of things, regulation can be understood as a lagging indicator that often achieves results at needlessly high cost. Were it not for rising affluence and technological innovation, regulation would have much the same effect as King Canute commanding the tides.

Charles, LFG may be a microcosm of the GOP is today, perhaps a bit more moderate. As you try and steer the forum toward facts without the politics, I see bloggers leave or get booted because they object to the intellectual honesty I see here by you and most Lizards.
The question is can the GOP get back to it's roots and win, if they lose the large numbers that really believe some of the stuff many moderates scoff at ?
Personally, I wonder how many will be left if the GOP looses the various deniers. Certainly the left has it's share of fringe elements, but they have no where to go.

Nothing like it since. We had droughts in the 30's and 50's, we built reservoirs and levees.Warming means longer growing seasons.Cold kills far more people than heat.

She writes:

You know the disinformation's bad when people are reading Sarah Palin's comments on health care and thinking they're true! After being laid off and having to deal with whether or not to insure my kids through COBRA ($1400/mo) when I had no income coming in and - when I got insurance after getting a new job - having to deal with all new doctors because the insurance plan was different, I truly believe people don't realize how precarious the current system is.

What action to take?

Now here is where we have the most disagreement. This is where we really need to think clearly and come up with rational solutions. Can we reverse man-made warming? Is it even possible with earth's population increasing by another couple billion people in the next 50 years?

The answer may very well be "humans are totally focked". In this case evolution comes in to play. Do we evolve and adapt to our warmer climate? We must.

Science has looked into all the variables that effect climate and the man made increase in CO2 is the only variable that has changed dramatically since the industrial revolution. Since we know CO2 has gone up, and we know it's a greenhouse gas, it's pretty much a slam dunk. Add to that, the fact that CO2 levels track the increase so closely, and it makes a stronger case.

Correlation is not the same thing as causation. It's a logical fallacy to assume that it is. No slam dunk.

The statement that there is no identified natural cause is key. There are many variables that are not identified. If everything was well known then the climate models would be able to predict current conditions based on historical input. They don't. Nothing predicted the leveling of temperature over the last decade. If there is something, I haven't found it.

There is no doubt human beings have an effect on the planet. The degree to which they do is still not sufficiently measured by science. This guy is quite arrogant and condescending in his delivery as well. "Mr. Know it All and the rest of you are stupid". My main problem with the radical proponents of AGW is not that they feel human activity is causing problems, it's their solutions to those problems. I reject the Kyoto Treaty as severely flawed.

Avanti sent this link to me one night when I dared challenge the gospel. This guy is smart and explains things in terms so that many who did not understand what the science says can get a better idea of what is being done in the area of research these days. Fair enough there.

Science is not my forte. Political stuff is one of my passions. The USA should never sign a treaty along the lines of Kyoto and for this guy to simply dismiss anyone who objects to it as being naive or stupid tells me a lot about his motivations. With Obama in, we might just open up our society to the jurisdiction of the UN and other world bodies, many of whom are hardly friendly to the USA. We rejected the treaty and used our own laws and motivations to curb our output of the evil gasses. And, we have reduced our numbers more efficiently than the Europeans who did adopt Kyoto. And, let's not forget about the largest polluter in the world, China. India is not far behind. This is where people like the author of this link lose me.

I agree with a few parts of your post. I think the debate should be what to about AGW, at what effect and cost. I also think it's wrong to be condescending to skeptics, even if their opinion have been formed by Fox TV or the constantly hearing only from skeptics.
i.e. if you guys tried to convince me against some long held personal beliefs, it would take a lot of facts before it sank in past my stubbornness. You would tale little bites around the edges, then I might listen closer before I came around.

re: #85 RebelDebater

Do you doubt that we contribute some of it?

107 Sharmuta  Sun, Aug 9, 2009 11:07:13am

Total Solar Irradiance (TSI): Also known as total incoming solar radiation (insolation). The amount of solar radiation reaching the Earth can change as solar activity changes. This is a known factor influencing global temperatures and thus climate. Sometimes people will reference sunspots, which correlate fairly well with TSI (more sunspots generally means more incoming solar radiation), but solar irradiance is the specific factor impacting the Earth's climate.

Since 1978 we've had satellites measuring TSI directly, and prior to that scientists use "proxies". A proxy variable is something that is probably not in itself of any great interest, but from which a variable of interest can be obtained. For example, climate scientists use tree rings and ice core layers as proxies to determine past global temperatures. In the case of TSI, one such proxy is beryllium-10 concentrations.

So the question again arises - could changes in TSI be responsible for the recent global warming? Since we've had satellites measuring TSI directly since 1978, and this is the period of the greatest warming in recent history (0.5 degrees Celsius over the past 30 years), all we have to do is look at the satellite data to determine if solar irradiance has similarly increased over that period.

Again, the answer is no. On average, TSI has remained essentially unchanged since 1978. According to the Max Planck Institute for Solar System Research, it hasn't increased (on average) in about 70 years.

115 kafir  Sun, Aug 9, 2009 11:08:31am

I try to stay out of the religious war called AGW. There is no upside, and the downside are lots of people with badly hurt feelings.

The links you posted include a number of very important critiques of his articles. One in particular is devastating, and he does not recover from it at all. Specifically this section is actually what a fairly large number of non-politicized scientists do think now. The third comment is devastating to his argument, specifically


1) You assume human intervention is the rule and require others to prove otherwise (example: they need to identify just what the mechanism is behind this alleged natural cycle.

This implies a testable hypothesis. It is untestable for a number of reasons.

That author clarifies his point in the fifth comment


Let's talk about your hypothesis: You can only statistically "reject" a null hypothesis. The only testable hypothesis is that humans caused global warming. The best case scenario for people that believe humans caused global warming is to "fail to reject" the null hypothesis. This does not mean (based on your background, I assume you know this) that we have proved that humans did cause global warming. It just means that it is possible that humans caused global warming - which is what I am asserting.

To be blunt, this is the crux of the counter-arguments. There is no testable case, and worse, no way to disambiguate signal from the noise.

Sadly, his entire site is written this way. Sort of the "knock the chip off my shoulder" approach to scientific arguments. The rebuttal might not seem so to most, but it is devastating to those who claim the evidence is irrefutable. The poster asked a simple question there, specifically, how you can claim that you have a signal, when you cannot measure the background ... the null hypothesis?

That is the core, the very essence of real science. If you cannot show an unambiguous signal, differentiated from the background, you are not talking about scientific results. You are talking pure conjecture.

The fundamental problem with AGW is that we know that in paleo-climatology, the earth has had many cooling and warming periods. Several scientists have postulated Snowball earth theories based upon data they have, but it would be correct to say that there is no consensus on this.

Despite loud protestations from the AGW community, there really is no consensus among scientists on AGW. Recently my own scientific society, American Physical Society, has had a near revolt over statements made by an editor-in-chief on this. Many are demanding he retract, several are demanding he step down.

I am personally disbelieve in AGW for a number of reasons. The foremost is that the existing real evidence points to a cyclical nature of heating and cooling, and is both a simpler theory, and better supported by observational data. Scientists tend to call that Occam's razor. The simpler theory usually is right. Not always.

The site's owner literally tries to discredit "unknown effects" as being possible to help explain the data they have. As a scientist, I find this sad. Scientists are *supposed* to be skeptics. They are supposed to not fall in love with theories.

AGW sadly, has more hallmarks of a religion than a science.

Is our climate changing? Yes. This is beyond dispute. We have evidence that demonstrates this.

Are we doing this? We don't know. We have, sadly, no way to know.

Should we continue to study this? Yes.

Should we strive for more efficient power production and transportation with a lower impact upon our environment? Obviously yes, but not for AGW reasons.

I buy into the It's the sun stupid theory myself. There is defiantly warming there's no denying it. I also believe we should be doing everything we can to stop burning all of the fossil fuels and putting the waste energy into the environment. That may very well be the cause of some if not all of the warming.

But to deny that a huge nuclear furnace that is the source of all life and basically the weather on our planet has little or nothing to do with warming is IMO as naïve as claiming there is no warming. I know there are counter arguments as you have posted Charles, but there are still those that believe the sun is the larger cause of warming. I also believe and read on one of the links from the site you linked to that the number of scientists buying into that theory is growing. Further some believe the warming cycle is over and a period of cooling has started which might become a very cool cycle.

Where I have issues with my thoughts on this is that if 100,000's of thousands of year old ice is melting now for the first time with the last ice age being about 12-13 thousand years ago why is now the first time that has happened.

It is hard to believe the first time this has happened is during my life time. So yeah I've contradicted myself at least once here. Then that's how it goes when the jury is still out for what is definite cause of warming. F.Y.I.

Conversely, show me the "proof" with respect to AGW. When scientists use words like "consensus", it's a time to be skeptical. At one period in history, it was the "scientific consensus" that black people evolved separately from white people, and that white people evolved from a "more beautiful" being located in the Caucasus mountain range. How did that "scientific consensus" hold up over time?

When scientists, who are financed, supported and motivated by political groups, begin to shout down their critics, it's also time to be skeptical - which something that the "believers" in AGW seemed to have checked at the door - their ability to be skeptical.

I'm open to being a skeptic, but not a skeptic motivated by politics. I hear the financed by and money involved, but don't get the profit motive for NASA, NOAA, or the EPA.

It's the sun, stupid

The blog is a good link, but biased, it puts the pro-AGW arguments in the best light and the anti-AGM arguments in the worst. That is not really honest.

Why doesn't this mention the eleven-year solar cycle?

And it may not be just the sun that warms the earth, recent news item said that the El Nino corresponds to global temperatures over the following year, and El Nino is probably (?) volcanic, anyway it's very unlikely to relate to solar.

Overall, I suppose I believe there is *some* degree of AGW, but it seems likely small, probably swamped by natural variation, and maybe we could use a little more warmth.

If it turns out we need to do something to fight *natural* variations, well, that's another subject.

OTOH, I'm all for limiting CO2 and carbon consumption and alternative energy, and was as a kid, before Paul Erlich was even a known name, or anybody at all was thinking about global warming.

And, weather or not, looks like finding enough fresh water for everyone on Earth is going to be a huge issue in the 21st and 22nd century, come what may, if anyone needs something to worry about.

re: #115 kafir

I try to stay out of the religious war called AGW. There is no upside, and the downside are lots of people with badly hurt feelings.

The links you posted include a number of very important critiques of his articles. One in particular is devastating, and he does not recover from it at all. Specifically this section is actually what a fairly large number of non-politicized scientists do think now. The third comment is devastating to his argument, specifically

To be blunt, this is the crux of the counter-arguments. There is no testable case, and worse, no way to disambiguate signal from the noise.

Sadly, his entire site is written this way. Sort of the "knock the chip off my shoulder" approach to scientific arguments. The rebuttal might not seem so to most, but it is devastating to those who claim the evidence is irrefutable. The poster asked a simple question there, specifically, how you can claim that you have a signal, when you cannot measure the background ... the null hypothesis?

That is the core, the very essence of real science. If you cannot show an unambiguous signal, differentiated from the background, you are not talking about scientific results. You are talking pure conjecture.

The fundamental problem with AGW is that we know that in paleo-climatology, the earth has had many cooling and warming periods. Several scientists have postulated Snowball earth theories based upon data they have, but it would be correct to say that there is no consensus on this.

Despite loud protestations from the AGW community, there really is no consensus among scientists on AGW. Recently my own scientific society, American Physical Society, has had a near revolt over statements made by an editor-in-chief on this. Many are demanding he retract, several are demanding he step down.

I am personally disbelieve in AGW for a number of reasons. The foremost is that the existing real evidence points to a cyclical nature of heating and cooling, and is both a simpler theory, and better supported by observational data. Scientists tend to call that Occam's razor. The simpler theory usually is right. Not always.

The site's owner literally tries to discredit "unknown effects" as being possible to help explain the data they have. As a scientist, I find this sad. Scientists are *supposed* to be skeptics. They are supposed to not fall in love with theories.

AGW sadly, has more hallmarks of a religion than a science.

Is our climate changing? Yes. This is beyond dispute. We have evidence that demonstrates this.

Are we doing this? We don't know. We have, sadly, no way to know.

Should we continue to study this? Yes.

Should we strive for more efficient power production and transportation with a lower impact upon our environment? Obviously yes, but not for AGW reasons.

Every one of your talking points is rebutted by the posts at the site, more data comes every day. If you are trying to say humans do not contribute some warming to the planet from our activities you are completely and provably wrong. A five year old can do it. So are you trying to say that in modern times we have not contributed to a warmer climate?

153 kafir  Sun, Aug 9, 2009 11:17:42am

Null hypothesis primer:

Place a thing to be measured somewhere. Place a measuring instrument somewhere. Measure, but with nothing connected. This is your background ... your "null" signal. Now connect to the thing to be measured. This is your signal. If your signal is inseparable from the background ... if you cannot statistically isolate a real non-background signal from your background (due to noise or whatnot else), your measurement is not yielding a signal you can talk about.

In order for this to work, you need two measurements. One with device connected to the experiment, one without.

We can't get that here. We have one measurement, and we don't know if it is the background or the attached.

I also didn't have space in the previous post to note that like AGW, I thought String Theory was a religion as well. Beautiful math, no way to test.

Then along comes someone and shows that a certain anti-deSitter spacetime provides a really nice way to describe superfluidity, which we can measure in the lab. In the process, they found a very nice similarity between black holes and quantized flow vortices in the superfluid.

This was ~6 months ago.

Maybe we will eventually see something testable emerge from the AGW crowd, a way to disambiguate the signal from the background. Real scientists and ex-ones like me, aren't holding our breaths. AlGore got a hold of this issue, and it has now largely lost any real scientific merits. Its now a talking point of one party.

Which it shouldn't be. Politics should stay way the hell away from science. Really.

154 dalejrfanfreak  Sun, Aug 9, 2009 11:17:51am

All of these temperatures are put into computer models that are subject to human error. This is why, for the United States, that 1932 became the hottest year on record when an error was found in the data FROM NASA, which previously showed 1998 was the hottest year on record (this first time I saw this was actually on LGF, go figure). On top of that, this has been one of the coolest summers for many areas in the Unites States (roughly 3,000 record low temperatures occurred in July), and snow is falling in places across the globe that haven't had snow in decades or even ever before. I think this youtube video (this is part 1, be sure to watch the other three parts) gives just about anyone some good reasons to be a global warming skeptic.

At the end of the day, I don't think either side of this debate knows what the heck is really going on. I can easily go to one website, read some info, then go to another and find something that contradicts that info. And it is for this reason that climate bills should not become law.

Let me add one more thing. The current AGW argument is a fossil.

The real AGW arguments were the virulent panic in the 1980s that involved hockey-stick predictions that the Earth would soon start on an irreversible heating that would raise average temperatures by - I dunno, ten, fifty, a hundred degrees, "like Venus" (which is hot enough to melt lead). Those arguments went away sometime in the late 1990s, I don't think even Gorebots spout them anymore. Now the arguments are about a couple of degrees celcius over centuries. MAYBE the coastlines will change a little, if that all pans out. But it does cause me more skepticism, when the previous panic has calmed itself by about 95% already.

It doesn't change the increase of greenhouse gases in the atmosphere, which can and likely will affect climate.

Look, Hon- we've been friends a long time, so you know I will give it to you straight. One of the items I read recently concerning climate was the recent book on the fossil Ida, The Link. (Amazing book, btw. Everyone should check it out. Ida is incredible.) They discuss the climate of the earth back in the Eocene era. There were no ice caps at that time, and plate tectonics was still at work.

The reason the did all this back ground on climate was to establish how a primate could be found in Germany. The earth was much different. One of the factors contributing to a warmer earth at that time was the ocean currents. They were completely different due to the placement of the continents. One factor that radically altered earth's climate was the shifting plates, and India creating the Tibetan Plateau and the Himalayas. This also affected ocean currents, and we still haven't discussed things like meteorites.

Small changes can and do have an impact on climate in ways we can't be sure of, but we are sure that man's contributions to increased greenhouse gases will have an impact.

To me whether there is global warming or not is not the question. The real question is whether or what action is warranted. Even accepting all the science that we're warming and the humans are causing it - it still is not a call for cap and trade or any other government boondoggle. Even if we - the USA could stop ALL greenhouse gas emissions today - it wouldn't change a thing as China and India are not going to do a thing to stop their emissions.

re: #135 Thanos

Actually I read through most of his "talking points". Mine are not. His rebuttals are weak, and in many cases poorly phrased. He is trying to win a political argument, not a scientific argument.

As I noted there is no upside. That you go ad-hominem, compare my reasoning abilities to a 5 year old suggests strongly that you are not open to refutation. Your response further strengthens my argument that this is in fact a religion. Which means pointing out that the null hypothesis is not disambiguated from the "real" signal will be lost on you, as it was him. Since that is the fundamental core of the rebuttal against his talking points, and he did not respond to it in a meaningful manner, its fairly easy to discount arguments based upon the incorrect premise. Since the entire premise of AGW rests on something not testable ...

[think house of cards, falling down]

No one denies the climate has changed and is changing. What we dispute is the impact humans have had on it, considering that there were larger faster swings in the past. The paleo-climatology record has all these in there. More credible explanations that fit observed data have been discovered recently, and the talking points site author admits he hasn't looked into and considered them, even though they do in fact appear to correlate far better than AGW "data".

As I said, it is a religion. Ad-hominems sadly expected, and at least the first have been seen here.

I don't agree with the politics of Kyoto or cap and trade either, so that's irrelevant to what we are discussing. Is the science provable? Too many on the right are saying no, which takes us out of serious consideration when discussing what we should or shouldn't do. IT's a stupid strategy to deny at the political level, and it's stupid to deny in the face of the ever increasing piles of evidence.

Our best stance on this is to oppose cap and trade through reason and by demonstrating that Cap and trade is too draconian for the degree or priority of the problem, that it doesn't work, and that it will enrich a few people at the expense of the economy. It will also likely cause a lot of people to starve.

re: #115 kafir

AGW sadly, has more hallmarks of a religion than a science.


It could well be that every claim made by AGW proponents are true. The problem, it seems to me, is not so much that AGW resembles a religion as much as AGW proponents often resemble missionaries.
The other problem, of course, is that AGW opponents often resemble flat-earthers.
Myself, I fall in more readily with the opponents just because of the shrieking one-issue zealotry of the AGW crowd, and their dubious solutions, which always seem to go in the same "agrarian" direction.

I read somewhere that there are three salient questions on this:
Is the planet warming in a non-cyclical manner?

It's possible that the current (and past) models are wrong, or in need of adjustment, but it doesn't matter.

It could relative to the scope of the mistake. Lets say the 'model" stated we'de increase temp by 1 degree. It comes out to be 5 degrees. a 4 degree difference
If the model was wrong and SHOULD have stated that we'd increase by 4 degrees and it actually increased to 5 (only a 1 degree diff.) then it would be inside of statistacal margein of error resulting in less hysteria

re: #135 Thanos

Every one of your talking points is rebutted by the posts at the site, more data comes every day. If you are trying to say humans do not contribute some warming to the planet from our activities you are completely and provably wrong. A five year old can do it. So are you trying to say that in modern times we have not contributed to a warmer climate?

Having read portions of the site I can see that if you read carefully you'll find that the ambiguity of the data and conclusions is easily apparent. Sea level rise is measured in mms. Especially when dubious statistical methods are applied to a vast range of different data and assumptions are assigned to hard-to-interpret data such as boreholes. The authors admit that these conclusions are not that precise. What we know: the earth may be in a warming trend (very likely) in the last 1000 years, and human activity MAY be contributing to it. Even the sited articles aren't able to assign a value to that. One part openly admits that CO2 emissions can't be the sole cause of AGW (if it exists). Like a lot of things in science we can know some things very precisely and others just can't. Too bad blowhards like Al Gore and some anti-AGW fanatics had to pollute the waters with their idiocy.

Again, the answer is no. On average, TSI has remained essentially unchanged since 1978. According to the Max Planck Institute for Solar System Research, it hasn't increased (on average) in about 70 years.

But the sun doesn't only emit light.

A research paper
summarized here describes a different mechanism by which solar activity may indirectly affect cloud formation and thus climate.

THey were based on real world data, there are over twenty of them, and they are constantly tuned. In large forecasting you adjust by looking at your prediction, and what really happened. You see where the model was off, and then correct the factors or assumptions you input. That's what the climate modelers have been doing for 20+ years. They are getting better at it, even as large scale manpower scheduling programs iteratively get better. They are never perfect either but they are able to accurately predict how many people you will need to staff in September at call center x.

I don't agree with the politics of Kyoto or cap and trade either, so that's irrelevant to what we are discussing. Is the science provable? Too many on the right are saying no, which takes us out of serious consideration when discussing what we should or shouldn't do. IT's a stupid strategy to deny at the political level, and it's stupid to deny in the face of the ever increasing piles of evidence.

Our best stance on this is to oppose cap and trade through reason and by demonstrating that Cap and trade is too draconian for the degree or priority of the problem, that it doesn't work, and that it will enrich a few people at the expense of the economy. It will also likely cause a lot of people to starve.

You can't get to that debate it half the party are running about saying "there's no such thing as global warming!"

Completely agree. Something in the weather is going on. Since the Dems are the one's paying attention to it, whether we are to blame or not, we better start in a big hurry before the only solution to pop up is exactly what is popping up.

Oh how I wish for the equivalent of a "block" list.

Thanos, you asked no questions. I pointed out that one of the commenters on the site did in fact devastate the entire fundamental scientific basis for AGW by asking how they could in fact measure either the null hypothesis or a signal. The site owner dithered and did not adequately answer that.

No strawmen were constructed, nor struck down in my post.

It may be something you believe in, so I am sorry if you feel I am attacking your belief system. As a science, it is left wanting. This is why so many of my fellow physicists have pointed this out, and why they are calling for the head of the editor-in-chief of one of the APS publications, over his comments that this is a "done deal". It is not, and demanding that it is, or constructing arguments like "knock the block off my shoulder, I dare you" do nothing to lend support to it.

AGW as a theory has problems, not the least of which, you can't measure the impact. Since the impact is in fact what the theory is saying is going to cause all manner of bad things going forward, and there is no way to measure it ...

This is why I try to stay away from arguing with creationists anymore as well. One showed up at a physics department I was at twenty years ago, and it unnerved me. I realized that when belief systems are questioned, people get bent out of shape. What they will do next, who knows.

AGW is the same way. Thank you for proving my point Thanos.

To me whether there is global warming or not is not the question. The real question is whether or what action is warranted. Even accepting all the science that we're warming and the humans are causing it - it still is not a call for cap and trade or any other government boondoggle. Even if we - the USA could stop ALL greenhouse gas emissions today - it wouldn't change a thing as China and India are not going to do a thing to stop their emissions.

I have my own rebuttal to Kyoto, which accomplishes nothing more than exporting jobs to China and India, while giving them a license to pollute.
If Japan produces one unit of environmental impact for every unit of productivity, then on that scale, America produces two units of impact per unit of production, and China, SEVEN.
Clearly, the solution is to bomb factories in China, which, as the economic substitution principle (theory?) operates, will clen up the environment considerably with minimal disruption to supply, as cleaner, unbombed factories expand to meet demand.
I'd like to see the environmentalists tell me why this "Modest Proposal" is less a good idea than the wanton destruction of productivity and economic performance contained within the Kyoto Protocol.

Two points only. First, a rebuttal to a rebuttal in this list. Second, well...
1) The "Greenland" and "Vineland" arguments stating the names were just sales pitches to get people to move there. Fine. It's only regional, hence anecdotal, you say, fine. But there is no rebuttal to (or mention of) the fact that since the mid 1990s the receding glaciers in Greenland have been giving up farms they covered some 500 years ago. Still giving them up. Still not back to where they were 500 years ago. Mmmm?

2) Never does this cheat sheet mention: The "science" (eg models) consistently predict the greatest increases in temperature to take place in the upper troposphere. Think of it as the "roof of the greenhouse". Not happening. So not happening that in 2007 a study of wind patterns in the upper troposphere was published to show that those wind patterns could only occur due to increased temperatures. Oops, it was a computer model, not a study. A computer model developed to rebut the more than fifty years of high altitude weather balloon temperature readings - which consistently show no increases in the upper troposphere temperatures at variance with surface temperature increases. Yes, the temp up there is going up - but not consistently with any of the models' projections. So the actual readings get thrown out in favor another model showing the temps are going up "the way they should".

Truly makes me wonder whether the science of AGW is more akin to the science that used to state "of course heavier objects fall faster than lighter ones" - until a man named Gallileo decided science should maybe be based on measurements, not assumptions.

I don't believe any climatologist would deny the sun, volcanoes, ocean currents, and other natural factors contribute to climate change. The issue is man's impact on climate. Since the issue is hotly debated, naturally it has been necessary to show these other factors are not the cause of the recent warming. This is not due to the wobble of our axis. This isn't due to TSI. This isn't due to a radical shift in ocean currents.

But you miss the point. Even if these things were contributing to climate change, it wouldn't change the atmospheric changes we are contributing.

Then you and I are close to agreement. AGW appears to be real enough, but what the hell to do about it ? Spend trillions trying to save energy, or a moon shot type plan to go almost all nuke ?

Man that makes a ton of sense - especially if AGW is as bad as they say. We need to go all nuke right now if we want even a slim chance of reversing GW.

And in other related news, this past July was the coldest on record in:

Grand Rapids Michigan

Huntington West Virginia

Fort Wayne Indiana

International Falls Minnesota

and Dubuque Iowa.

Seattle had a couple days that were the hottest recorded, but they also place their surface station next to an airport runway.

It's been hotter than average here in AZ this summer. We had a great June, but we've been paying for it since. When your low is 98, you know it's going to be a bad day.

Ugh. Rathole detected. Will try not to get sucked in.

"Darwinism" isnt a religion. It is a testable hypothesis. You can stick evolution in a lab and observe it. You can refute it by finding real counterexamples, and showing that a different process is at work. That it has survived with minor changes over 150 years is a pretty good testament to how successful it is as a theory.

Creationism is a religion. You cannot test it, because in testing it, you could refute it. If you refute it, you are refuting a religion.

re: #218 kafir

Oh how I wish for the equivalent of a "block" list.

Thanos, you asked no questions. I pointed out that one of the commenters on the site did in fact devastate the entire fundamental scientific basis for AGW by asking how they could in fact measure either the null hypothesis or a signal. The site owner dithered and did not adequately answer that.

No strawmen were constructed, nor struck down in my post.

It may be something you believe in, so I am sorry if you feel I am attacking your belief system. As a science, it is left wanting. This is why so many of my fellow physicists have pointed this out, and why they are calling for the head of the editor-in-chief of one of the APS publications, over his comments that this is a "done deal". It is not, and demanding that it is, or constructing arguments like "knock the block off my shoulder, I dare you" do nothing to lend support to it.

AGW as a theory has problems, not the least of which, you can't measure the impact. Since the impact is in fact what the theory is saying is going to cause all manner of bad things going forward, and there is no way to measure it ...

This is why I try to stay away from arguing with creationists anymore as well. One showed up at a physics department I was at twenty years ago, and it unnerved me. I realized that when belief systems are questioned, people get bent out of shape. What they will do next, who knows.

AGW is the same way. Thank you for proving my point Thanos.


Right here. Question marks are punction that mean a question was asked.

I'll repeat it again try to be concise in your answer, we don't need war and peace, and when people type three paras for what could be said in a sentence or two I suspect obfuscation...

The only way we'll ever be able to realistically debate political solutions is if we start by accepting a few baseline realities.

The scientific evidence that humans are responsible for an alarmingly rapid rise in global temperature is pretty overwhelming at this point. I'm not taking anybody's word for this, either -- I've been reading a lot on this subject, from all sides, for the past year or so.

Call me a traitor, call me a RINO, call me late for dinner, but it's really clear to me that the Republican Party has been responsible for a vast amount of disinformation on climate science. Both sides are guilty of exaggeration and hype, but the right wing side has distorted the truth far beyond what I see from the scientists -- who may not be perfect, but are only rarely outright liars.

This is a very sad situation, because I happen to believe it's very much a conservative value to behave responsibly toward the environment. The stuff coming from Michele Bachmann, James Inhofe, etc. is just unconscionable and completely betrays conservative principles in my view.

That is not a new phenomena. It is as old as the club and ax.

For example, my wife worked for 'at risk' youths. (I am sure you know this example coming up.) One of the techniques used, as does anyone in sales, is to offer 2 choices...never just ask if someone wants something...you get a better chance of a 'yes'. "Would you like the 'X' color or the 'Y' color."

So thinking I got the parental thing down with this technique I go to my 3 year old (at the time, currently 5), "Would you like the 'Pancake' for breakfast, or the 'French Toast' for breakfast?"

To which he replied, "None! Better idea, number 3! I make my own chocolate milk, I don't want to eat!" (I would have NEVER, EVER, in a million years thought to do something like that when I was that age...)

We have bought into the 2 party system for long enough...they are leading us down their own mazes...there has to be a 3rd solution. So we just question authority and figure out the right way and do all we can to defend our wallets for the upcoming climate change theft. GODSPEED all you inventors!! HURRY IT UP!!!

Flying High: Remembering Barry Goldwater by William F. Buckley

There are a couple stories in there that illustrate Senator Goldwater's feelings on science. One is he and Buckley went to Antarctica, and one of the little gifts Buckley thought up was to bottle some glacial ice millions of years old. Years later, Goldwater pulled it out of a desk drawer in his home office to show Buckley just how much he still thought of his million years old water.

I can't believe he would approve of the anti-science streak in the current GOP. It's palinly spelled out in The Conscience of a Conservative that he placed value on science education. If people think anti-science is a conservative value, they are flat out wrong.

I think that there is something there in AGW but have real doubts of the extent of the problem and solutions. The politicization and the way this is being "sold" from both camps is discouraging. I'm really pretty dissatisfied with most of the front-men on both sides of this topic and unfortunately this can set up an emotional reaction of not wanting to have anything to do with either side, which ultimately is unproductive.

Have you ever walked into a car showroom and been ooohing and aaahing at the cars? Then the salesman comes over and he/she is total asshat trying to get a commission out of you. I usually walk out of the place, even if I'm in the market for a new vehicle.

This is how I'm starting to view many of the mouthpieces of both sides of the movement. Asshat car salesmen working on me for their commission.

This is unfortunate, because the truth exists somewhere and it is important that we understand the truth. Just wish the asshat salesmen would get out of the way.

The science may indeed revise its "plans" based on new information. If, however, a core sample of the science from a particular moment in time is codified into law, there is no reason to assume that the laws thus enacted will change based upon the new information.

Exactly. Which is why we need to approach this from reason and accept the facts that are. There's oodles of proof that cap and trade fails in objective and crushes economies, Europe increased gas and coal use, the current recession, and Enron's collapse are just a few examples. [most people don't understand that Enron was really set up to do cap and trade, and they've forgotten those rolling brown outs in CA.]

I'll repeat it again try to be concise in your answer, we don't need war and peace, and when people type three paras for what could be said in a sentence or two I suspect obfuscation...

So are you trying to say that in modern times we have not contributed to a warmer climate?

Notice the ad-hominem. The argument will be lost on Thanos, regardless of its correctness.

Thanos, we simply do not know whether or not we have contributed to a warmer climate. There is no signal we can measure that is disambiguated from a null hypothesis of no contribution, that in any way shape or form, allows us to conclusively and authoritatively state that we, human beings, have definitively contributed to a warmer climate.

Moreover, those who claim this, such as that site's owner, specifically dither on points which are shown to be problematic for their concept.

Whether you like it or not, and from your tone and multiple juvenile attacks, I assume you do not like it, the null hypothesis test is the fundamental problem of AGW. Until you can get that signal, the only thing

THE ONLY THING

you can conclusively say, with any degree of accuracy, is

WE DON"T KNOW.

Which is what I said.

If you want to keep arguing, go right ahead. But arguing doesn't change the fact that you can't actually tell if climatic changes are human caused. You can postulate, you can theorize, you can model. You cannot definitively state that humans are the cause, because you cannot reject the possibility that humans are not the cause, again, because we have no signal to detect.

"We don't know" is the most accurate statement that can be made to date.

Do we need to sequester carbon? Probably not, but I see huge financial interests pushing this stuff hard.

Do we need to get more efficient vehicles and transport? Yes. Consuming less energy and waste less energy is good regardless of AGW (in)validity.

Do we need to be more careful of our environment, and try to reduce pollutants? Absolutely. There is credible substantial evidence of concentration of pollutants being linked to ecological changes that impact humans, animals, and flora in a very negative manner.

Do we need to sign on to Kyoto, do cap and trade, etc? Unlikely. We need something more intelligently designed for emission reduction. RoHS is a good start for EU, and there are several other initiatives like that.

GCC needs far more study and funding. We need to pull the politics and money back from it, and look at it closely, with a skeptics eye. Or we are doing everyone a disservice.

re: #305 Sharmuta

This is for anyone who'd like to read a little more on Goldwater and science on a more personal level:

Flying High: Remembering Barry Goldwater by William F. Buckley

There are a couple stories in there that illustrate Senator Goldwater's feelings on science. One is he and Buckley went to Antarctica, and one of the little gifts Buckley thought up was to bottle some glacial ice millions of years old. Years later, Goldwater pulled it out of a desk drawer in his home office to show Buckley just how much he still thought of his million years old water.

I can't believe he would approve of the anti-science streak in the current GOP. It's palinly spelled out in The Conscience of a Conservative that he placed value on science education. If people think anti-science is a conservative value, they are flat out wrong.

So you are saying it makes no sense? 'Palinly' and Plainly are radically different concepts...

You do notice that some proponents swithched from Global Warming to "Climate Change" & Hollywood even went to 'Global Chaos."

As I have pointed out the name climate change is a better description of what AGW causes. Not just warming, but floods, storms, drought, the works, in a complex weather system.

For example, my wife worked for 'at risk' youths. (I am sure you know this example coming up.) One of the techniques used, as does anyone in sales, is to offer 2 choices...never just ask if someone wants something...you get a better chance of a 'yes'. "Would you like the 'X' color or the 'Y' color."

So thinking I got the parental thing down with this technique I go to my 3 year old (at the time, currently 5), "Would you like the 'Pancake' for breakfast, or the 'French Toast' for breakfast?"

To which he replied, "None! Better idea, number 3! I make my own chocolate milk, I don't want to eat!" (I would have NEVER, EVER, in a million years thought to do something like that when I was that age...)

We have bought into the 2 party system for long enough...they are leading us down their own mazes...there has to be a 3rd solution. So we just question authority and figure out the right way and do all we can to defend our wallets for the upcoming climate change theft. GODSPEED all you inventors!! HURRY IT UP!!!

The two-party system is an almost definitional result of the sound principles our Republic (not Democracy) is founded upon. Founding third parties is fine, but working to destroy the two-party system implies, by necessity, an eventual assault on the structure of Congress, which for all its manifold and nefarious flaws is still the finest system instituted by Man. I'll defend it.
So ROLL ON, two-party system. Now if you want two *different* parties, I'm with you.

(Who knows, MW could have been a similar current shift?) Perhaps I'm being dense, but I don't see how that advances or even supports AGW? Without the recent shift in currents, Greenland's ice sheet would still be growing? Does that take all Greenland observations off the table in favor of AGW? Some of them? None of them?

Heh. I'm as skeptical/agnostic on global warming as many lizards but it baffles me that denial of global warming is a "conservative value". Seems self destructive to me.

I have a feeling of dejas vu here.
Traditionally, to be conservative was to prefer the rural to the urban, to distrust innovation, to believe that mankind has dominion over the Earth but that meant husbandry (guardianship, hunstsmen not hunting to extinction, farmers leaving fallow lands). Prudence and thrift were also conservative virtues.
Republicans no doubt continue to love nature, and many may be traditionalist enough to see CO2 as a proxy for innovative excess and the spread of urban pollution (literally and metaphorically) over rural simplicity. They are moved by arguments of " an ounce of prevention etc. " when it comes to controlling CO2 emissions.
Political conservatives (post Adam Smith) support capitalism, hence a political antipathy to huge regulation of economic activity.
So, conservative "values" (or cultural biases) and conservative politics may well be contradictory over global climate change.

Late to threads as usual (now when we are discussing Buzz and slips...)

But...
I think it is fascinating to see that the planet is trying to correct the excess of CO2 by mass producing seaweed (such that the coast of CA folks are driven insane by the growth problems). Nature takes a logical path and creates weed-like answers to the CO2 excess.

Now, if in fact this GW poses a profound problem for us in a "very soon - near term" time frame with the weather / oceanic current corridor shutting down from the salinity imbalances and thus our climate as a whole then there is a serious problem requiring attention - a fast ice age ensues because the currents and weather simply stop...

The problem I am having is that the approach seems to be this political emissions attack, instead of a two pronged logical approach that addresses output by the green energy sources and the plant solution side by growing edible seaweeds or other greens that will efficiently absorb the emissions en masse.

WE have the technology, we NEED the food sources, why not marry solutions without the power plays and economic malfeasance if we see that the warming trends are going to definitely cause these kinds of problems?!!?

My frustration is that there is too often not enough evaluation of the consequences to our actions and only knee jerk responses that end up causing worse problems we didn't consider.

374 HelloDare  Sun, Aug 9, 2009 12:14:52pm

The big question I have about GW is whether CO2 drives a rise in temperature or vice versa. What about this purported 200 to 100 or 600 to 1200 year lag between a rise in temperature and then a rise in CO2. This post [Link: scienceblogs.com...] didn't answer the question in my mind. What about a simple graph on a scale that could show whether or not it's true.

And doesn't the post you find below from Real Climate argue against using the rise in current levels of CO2 ( the last 100 years or so) as evidence for our current rise in temperature?

And why is "Some (currently unknown) process" only in play at glacial terminations. Why couldn't this process be at play now.

This is an issue that is often misunderstood in the public sphere and media, so it is worth spending some time to explain it and clarify it. At least three careful ice core studies have shown that CO2 starts to rise about 800 years (600-1000 years) after Antarctic temperature during glacial terminations. These terminations are pronounced warming periods that mark the ends of the ice ages that happen every 100,000 years or so.

Does this prove that CO2 doesn’t cause global warming? The answer is no.

The reason has to do with the fact that the warmings take about 5000 years to be complete. The lag is only 800 years. All that the lag shows is that CO2 did not cause the first 800 years of warming, out of the 5000 year trend. The other 4200 years of warming could in fact have been caused by CO2, as far as we can tell from this ice core data.

The 4200 years of warming make up about 5/6 of the total warming. So CO2 could have caused the last 5/6 of the warming, but could not have caused the first 1/6 of the warming.

It comes as no surprise that other factors besides CO2 affect climate. Changes in the amount of summer sunshine, due to changes in the Earth’s orbit around the sun that happen every 21,000 years, have long been known to affect the comings and goings of ice ages. Atlantic ocean circulation slowdowns are thought to warm Antarctica, also.

From studying all the available data (not just ice cores), the probable sequence of events at a termination goes something like this. Some (currently unknown) process causes Antarctica and the surrounding ocean to warm. This process also causes CO2 to start rising, about 800 years later. Then CO2 further warms the whole planet, because of its heat-trapping properties. This leads to even further CO2 release. So CO2 during ice ages should be thought of as a “feedback”, much like the feedback that results from putting a microphone too near to a loudspeaker.

In other words, CO2 does not initiate the warmings, but acts as an amplifier once they are underway. From model estimates, CO2 (along with other greenhouse gases CH4 and N2O) causes about half of the full glacial-to-interglacial warming.

So, in summary, the lag of CO2 behind temperature doesn’t tell us much about global warming. [But it may give us a very interesting clue about why CO2 rises at the ends of ice ages. The 800-year lag is about the amount of time required to flush out the deep ocean through natural ocean currents. So CO2 might be stored in the deep ocean during ice ages, and then get released when the climate warms.

375 zombie  Sun, Aug 9, 2009 12:15:07pm

Thanks for linking to this debunking blog post at Science Blogs, Charles, because it absolutely confirms my main objection to the climate change hysteria.

But wait -- in what manner does this debunking post confirm my skepticism?

Because on the one most important objection, it has a very very weak response; and if that is the best argument they can provide as their debunking, it means that my objection on this key point has not really been debunked anywhere.

It's this "Objection" and "Answer":

Objection:

The Earth has had much warmer climates in the past, what is so special about the current climate? It seems like a generally warmer world will be better.

Answer:

I don't know if there is a meaningful way to define an "optimum" average temperature for planet Earth. Surely it is better now for all of us than it was 20,000 years ago when so much land was trapped beneath ice sheets. But anywhere between the recent climate and the most extreme one we may be heading for with tropical forests inside the arctic circle, one global mean temperature seems just as good as any other. Maybe it is even better with no ice caps anywhere.

But the critical issue with what is going on today is not where the temperature is or would be and not with what it may end up being. The critical issue is how fast it is moving.

Rapid change is the real danger. Human habits and infrastructure are suited to particular weather patterns and sea levels, as are ecosystems and animal behaviors. The rate at which the global temperature is rising today is very likely unique in the history of our species.

This kind of sudden change is even very rare in geological history, though perhaps not unprecedented. So the planet may have been through similar things before, that sounds reassuring, right? Well, once you look at the impact similar changes had on biodiversity at the time, the existence of some historical precedent or another actually becomes anything but reassuring. Rapid climate change is the prime suspect in most of the mass extinction events, including the Great Dying some 250 million years ago, in which 90% of all life went extinct.

What we know about ecosystems and what geologic history demonstrates is that dramatic climate changes - up or down or sideways - are a tremendous shock to the biosphere and cause mass extinction events. And that, all in all, is not likely to be a good thing.

That's it? That's their answer? That's the best-known debunking of the "Why would a somewhat warming world be worse than our currnt climate?" objection? Absolutely weak.

All ecosystems have a life-cycle and a level of biodiversity. But Arctic and sub-arctic ecosystems have the LEAST amount of biodiversity -- whereas tropical and subtropical climate have the GREATEST level of biodiversity. So his nightmare scenario of "tropical forests inside the arctic circle" would INCREASE biodiversity overall.

If the worst-case scenarios are true, then yes, that small handful of species that can only survive in the freezing arctic will suffer. Some might even go extinct. But at the other end of the scale, those species that thrive in tropical or subtropical ecosystems -- some of which are currently very rare -- will likely thrive and grow in numbers, because their habitat will expand. And the number of species that will benefit from the gradual tropicalization of the planet is vastly greater than the number of Arctic species that might suffer.

I have never seen a valid reply to this position. And this Science Blog post fall right in line with the "no real answer" to that objection.

Climate science is one issue, and what policy is based on is another issue. Climate science is far from transparent, particularly when trillions of dollars rest on predictions based upon it.

[Link: www.climateaudit.org...]

is a great place to get a feel for what is going on in terms of self-auditing and transparency in a format that is explicitly non-political (steve deletes OT posts pretty ruthlessly). That said, errors in climate science are strangely very much like party attribution in political scandals in the press... one sided.

CA is not an easy read unless you are very well versed in statistics. OTOH, people who don't understand CA also shouldn't be making policy based on climate science, IMO.

IMO, in order to justify great expense in the name of saving the planet from warming, the AGW camp needs to clearly demonstrate (and show their work 100%, every line of code—as their own journals demand, but they refuse to comply with, even when hit with FOIA requests) that humans are driving this change outside of the "natural" envelope of change (the earth has no ideal, stable temperature, it is a constantly changing, dynamic system). They also need to demonstrate that the proposed solution is cost effective vs other measures—and that any such solution will work.

Right now, we have massive expenditures proposed for "solutions" that they cannot predict will actually work, or are explicitly not enough to work based on their own alarmism.

re: #265 Sharmuta

Belief without incontrovertible evidence. The whole null hypothesis bit I've been talking about. Some here have bought the arguments for AGW hook line and sinker. Some have pointed out that the evidence that does exist isn't incontrovertible, in large part because there is no way to disambiguate the null hypothesis data. There is technically no signal, you can't measure voltage within a circuit with a single contact, you need two points so you can measure the signal relative to something. That something is the background. Without knowing the background, it doesn't matter how persuasive they can be, it is a belief system. Because you can only speculate on the background, which is what pro-AGW do.

I am not ignoring the tactics of the anti-AGW crowd.

I just want both to stop foisting their beliefs upon us and let, hopefully non-politicized, scientists get to figuring out if there really is a signal there. Right now the answer, despite the best efforts to paint it otherwise, is no. We can't see the signal.

That doesn't mean it isn't happening. Just that we can't say that it is happening and be absolutely sure that is correct.

You have to believe in AGW to accept it, because of the problem with the data. Belief has no place in science. It is the basis of religion. Belief fills in the void for lack of evidence. And when you challenge the belief with very simple, yet very hard to dismiss basic science, you get people jumping down your throat, making you regret speaking up about this.

Thats why it is a religion.

Is it happening. We do not know. Should we study it more? Hell yes.

I don't think anything is 'off the table.' It's all connected. Something has to change when so much more CO2 is released than previously.

Indisputably. CO2 absorbs heat - measurably. What, to my mind, remains uncertain is how CO2's absorption can justifiably (sp?) be multiplied many times over and above that observable rate in order to advance the theory of AGW.

No -- that is a gross understatement.

Evolution is established theory and is completely beyond debunking, dispute or skepticism. It has been conclusively proved experimentally countless times.

Catastrophic AGW is a hypothetical projection of data points hundreds of years out into the future. it is not a theory. it is not even a hypothesis. It is simply a pointing to a trend line on a graph and saying, "Hmmm, on a centuries-long scale, this line is trending up." That's not the same thing as a "scientific theory," and catastrophic AGW is not in the same category as evolution.

re: #383 avanti

I read that. That's where I got the Real Climate link. Which once again said this (my emphasis) :

From studying all the available data (not just ice cores), the probable sequence of events at a termination goes something like this. Some (currently unknown) process causes Antarctica and the surrounding ocean to warm. This process also causes CO2 to start rising, about 800 years later. Then CO2 further warms the whole planet, because of its heat-trapping properties. This leads to even further CO2 release. So CO2 during ice ages should be thought of as a “feedback”, much like the feedback that results from putting a microphone too near to a loudspeaker.

In other words, CO2 does not initiate the warmings, but acts as an amplifier once they are underway. From model estimates, CO2 (along with other greenhouse gases CH4 and N2O) causes about half of the full glacial-to-interglacial warming.

That currently unknown process only happens at glacial terminations?

A recent Nature study suggested that Greenland's ice sheet will begin to melt if the temperature there rises by 3 degrees Celsius (5.4 degrees Fahrenheit). That is something many scientists think is likely to happen in another hundred years.

The complete melting of Greenland would raise sea levels by 7 meters (23 feet). But even a partial melting would cause a one-meter (three-foot) rise. Such a rise would have a devastating impact on low-lying island countries, such as the Indian Ocean's Maldives, which would be entirely submerged.

re: #34 avanti

Part of science is searching for just that sort of answer. Science has looked into all the variables that effect climate and the man made increase in CO2 is the only variable that has changed dramatically since the industrial revolution. Since we know CO2 has gone up, and we know it's a greenhouse gas, it's pretty much a slam dunk. Add to that, the fact that CO2 levels track the increase so closely, and it makes a stronger case.

Science has not looked into all the variables that effect climate. This is a fallacy. Please look at Svensmark et al. They have just published a paper. When warmists dismiss the effects of the sun they look at TI - total irradiance. But cosmoclimatologists are contributing new understanding of cloud formation.

Back when I got my philosophy degree, professors used to talk about beliefs that one held tightly and ones that one held loosely and instances where one could simply withhold having an opinion. Regarding AGW, I am moving from withholding opinion to believing in AGW but holding that belief loosely. I am enjoying the debate. I liked the link that started this thread, mostly good science... however there are some of the arguments that could have toned down some of the emotional words.

And what should we call it when the science stands up to the scrutiny? "Consensus" worked- at least it did when the scientific community applied it to evolution.

And when exactly did "consensus" work for evolution? What was the consensus on evolution before the Origin of Species was published? For that matter, what would be the "consensus" on evolution in the Texas school board, today?

The truth is always where it is, regardless of "consensus" or other aspects of belief systems. There are reasons to think AGW may be factual but consensus (for or against) is not among them.

I don't doubt our globe is warming, but I am a skeptic because of how politicized it's become, and the convenient truth about how those in power can turn a profit from it - namely Al Gore through his carbon offsets.

When politicians use a science to cry "The sky is falling!" then propose answers to that cry that involve our money and sweeping changes in the way live and work, I become suspect.

I would also like to see less rhetoric from both the pro's and con's - let science take its course. Einstein did not embrace Heisenberg's uncertainty principle. He said (about the EPR experiment proving improbability in physics)"the more success the quantum theory has, the sillier it looks."

Let science work itself out without demonizing one side or the other. Neither marginalize those who dispute GW, nor idolize the proponents. Just as many of us believe we shouldn't mix science and faith in the classroom, let's not mix science and politics either.

But putting the inappropriate application of the Null Hypothesis aside, we are indeed well outside the realms of natural global variability as seen over the last two thousand years and even over the last 12,000 years. We can go back several hundreds of thousands of years and we still see that the temperature swings of the glacial/interglacial cycles were an order of magnitude slower than the warming rate we are now experiencing. In fact, outside of catastrophic geological events like the Paleocene Eocene Thermal Maximum there are no known precedents for warming this fast on a global scale. I'd say the case for "it's all natural" is the one that needs explaining.

Dozens of mountain lakes in Nepal and Bhutan are so swollen from melting glaciers that they could burst their seams in the next five years and devastate many Himalayan villages, warns a new report from the United Nations.

It's hardly news that the world's glaciers are melting—a phenomenon widely attributed to gradually rising global temperatures. But the possible consequences in terms of human deaths and loss of property have reached greater urgency in light of the findings of the new study.

re: #375 zombie

Thanks for linking to this debunking blog post at Science Blogs, Charles, because it absolutely confirms my main objection to the climate change hysteria.

But wait -- in what manner does this debunking post confirm my skepticism?

Because on the one most important objection, it has a very very weak response; and if that is the best argument they can provide as their debunking, it means that my objection on this key point has not really been debunked anywhere.

It's this "Objection" and "Answer":

Objection:

That's it? That's their answer? That's the best-known debunking of the "Why would a somewhat warming world be worse than our currnt climate?" objection? Absolutely weak.

All ecosystems have a life-cycle and a level of biodiversity. But Arctic and sub-arctic ecosystems have the LEAST amount of biodiversity -- whereas tropical and subtropical climate have the GREATEST level of biodiversity. So his nightmare scenario of "tropical forests inside the arctic circle" would INCREASE biodiversity overall.

If the worst-case scenarios are true, then yes, that small handful of species that can only survive in the freezing arctic will suffer. Some might even go extinct. But at the other end of the scale, those species that thrive in tropical or subtropical ecosystems -- some of which are currently very rare -- will likely thrive and grow in numbers, because their habitat will expand. And the number of species that will benefit from the gradual tropicalization of the planet is vastly greater than the number of Arctic species that might suffer.

I have never seen a valid reply to this position. And this Science Blog post fall right in line with the "no real answer" to that objection.

Good god. Zombie, supposing the climate had altered so radically that there were tropical forests inside the arctic circle, what do you think that would mean for the places that have tropical forests in them NOW?

Kafir:

One more thing now that I've shown you to be demonstrably in denial of reality in a public forum. If you had bothered to even glance at the links in the page Charles posted above you would have found the smack down for your null hypothesis bullshit

[Link: scienceblogs.com...]

point, set, and match.

Oy vey.

Ok, I'm going to sink to your level. This "refutation" of the point is utter BS, and this has been pointed out in the comments. More to the point, if you think null hypothesis is BS, well, that says something about you now, doesn't it. It means you don't have a clue about what you write, and you take your talking points off someones web site, someone with an obvious agenda, who glosses over the argument with a weak counter. That doesn't address the point.


But putting the inappropriate application of the Null Hypothesis aside, we are indeed well

In all the refereed journal articles I've published (a number over a 20 year career), if someone calls BS on a fundamental argument, they better back it up right there.

He doesn't. He simply claims it is inappropriate by saying that you don't really need a statistical correlation between CO2 and temperature to say AGW is working. In fact the original quote is


Natural variability is the null hypothesis and an anthropogenic CO2 warming effect needs compelling evidence before there is any reason to take it seriously.

This is true. This is absolutely one hundred percent correct. The compelling evidence is the disambiguous signal that we are deviating from natural variability.

He states


The null hypothesis is a statistical test and might be a reasonable approach if we were looking only for statistical correlation between increasing CO2 and increasing temperature.

Since anthropogenic warming *is* increasing temperature with CO2 concentration, he admits that it is a reasonable test for a statistical correlation between CO2 concentration and temperature.

And then goes on to try to deny that it is next.


But we're not, there are known mechanisms involved whose effects can be predicted and measured. These effects are the results of simple laws of physics even if their interactions are quite complex.

... which he doesn't go into, and doesn't describe. We call this in science, a hand waving argument. You use this when you don't know the right answer, but you want someone to adopt your view for the moment.

It isn't a reasonable argument. If CO2 concentration correlates with temperature we would see it.

But as every physicist learns way early in their career, correlation DOES NOT IMPLY causality. Unfortunately he doesn't seem to grasp this. They are actually anti-correlated, that is CO2 is a lagging indicator relative to temperature, and this gives AGW folks fits trying to explain that. Again, this is well know, and in the primary literature.



outside the realms of natural global variability as seen over the last two thousand years and even over the last 12,000 years. We can go back several hundreds of thousands of years and we still see that the temperature swings of the glacial/interglacial cycles were an order of magnitude slower than the warming rate we are now experiencing. In fact, outside of catastrophic geological events like the Paleocene Eocene Thermal Maximum there are no known precedents for warming this fast on a global scale.

Here he makes a fundamental assumption that all causes of GW are the same, unless forced otherwise. This is a profound assumption. Given the dynamic nature of our Sun-earth system, one that is very very hard to support. More in the next post.

This site is just as bad as all the others. They say things with no basis in fact, no references. It is of no use to anyone, except to point out the flawed logic of the AGW proponent.

While it is undoubtably true that there are some cycles and natural variations in global climate, anyone who wishes to insist that the current warming is purely natural or even just mostly natural has two challenges. Firstly, they need to identify just what the mechanism is behind this alleged natural cycle, because absent a forcing of some sort, there will be no change in global energy balance. So natural or otherwise, we should be able to find this mysterious cause. Secondly, a "natural cause" proponent needs to come up with some explanation for how a 35% increase in the second most important greenhouse gas does not itself affect the global temperature. Theory predicts that the temperature will rise given an enhanced greenhouse effect, how is it possible this is not happening?

Firstly, why does the skeptic need to identify the mechanism? How can one identify the mechanism when it is beyond their comprehension? How is saying the AGW theory is devoid of any more proof than the "natural cause" theory put the burden on me? It does because if you put the burden on the AGW proponent, like Hansen, all his tests and predictions are laid to rest as wrong by the simple passing of time.

Secondly, CO2 being a greenhouse gas is all a matter of degree. Saying it's the second most important is very intellectually dishonest when adding CO2 has a diminshing effect as more is added. No one (sane) is denying it is a greenhouse gas, it's a LONG way from that to AGW.

Bottom line is that all AGW theories predict/require a warming upper atmosphere. Hasn't happened. All AGW theroies predict/require a warning ocean. Hasn't happeneed.

Throughout it all the solar cycles track the climate.

That's just it. We need to come up with ideas. Apply some of that famous American ingenuity. I don't know why folks seem to think infrastructure needs should limit green energy resources. It would create much needed jobs to start the needed work. They're not going to spring up over night, so why not start working towards this goal now? Wind and solar should certainly continue to be viewed as helpful while we work towards better solutions. It's not as if our desire for energy will stop, so I think adding wind and solar to boost increased demand should be a part of the plan. We need more and better ideas than this though.

I described those simple laws of physics to you upthread where you attempted to deny the reality that we contribute some to global warming. It's irrefutable that CO2 blocks some infrared radiation, do you doubt that? It's irrefutable that we contribute CO2, Methane, NO2, and other compounds that are not transparent to infrared radiation. We contribute. That's irrefutable, that's reality. Your argument is mooted by his statements and by those realities. We know there is some effect. He then goes on to show data that proves that what we are seeing now does stand out in a background of 2000 years, 12000 years, and for most of time.

Now you can keep repeating your mantra ad infinitum, it doesn't change reality. It doesn't change the fact that your null hypothesis doesn't fit, and besides that even if you apply it it's proven.

Also, I should point out something that's coming up in my next report on John Holdren:

Holdren, as you may know, is not only our current "Science Czar" but he's also one of the main architects of and proponents of contemporary AGW theory -- and he was the one who made the legendary projection-graphs for Al Gore's "An Inconvenient Truth" presentation and film.

Holdren is a fierce advocate of the "Scientists (especially me) say it is true, therefore it is true" position.

But here's Holdren writing thirty years ago:

"This screening phenomenon is said to be responsible for the present world cooling trend -- a total of about 2 degrees C in the world mean surface temprature over the past quarter century. This number seems small until it is realized that a decrease of only 4 degrees would probably be sufficient to start another ice age. Moreover, other effects besides simple screening by air pollution threaten to move us in the same direction. In partiucular, a mere one percent increase in low cloud cover would devcrease the surface temperature by .8 degrees C. We may be in the process of providing just such a cloud increase, and more, by adding man-made condensation nuclei to the atmosphere in the form of jet exhausts and outher suitable pollutants. A final push in the cooling direction comes from man-made change in the direct reflectivity of the ewarth's surface (labedo) through urbanization, deforestation, and the enlargement of deserts.

The effect of a new ice age on agriculture and the supportability of large human population scarely need elaboration here. Even more dramatic results and possible, however;. for instance a sudden outward slumping in the Antarctic ice cap, induced by added weight, could generate a tidal wave of proportions unprecedented in recorded history."

Could he have even been any wronger?

Holdren is the one whose credibility is approaching zero. It's quite obvious that he fishes around for doomsday scenarios and latches on to whatever one looks promising at that particular moment.

His motivation is to create panic, not promote sound science.

Considering that John "Ice Age" Holdren is one of the main proponents of the current catastrophic AGW hysteria, suddenly the whole thing looks fishy.

From your link:

"It looks like it's the Westerlies," Shroder said, referring to strong jets of wind that pour from west to east in a belt around the planet. Though he can't say for certain, the winds appear to be carrying more moisture from the warming Atlantic Ocean and Mediterranean Sea eastward.

If that's true, some of the moisture would fall into the region around the Caspian Sea. But as the winds rise into Karakoram's frigid heights, any remaining water would come down as snow, feeding the glaciers.

"We will see regional patterns like this developing as climate change alters precipitation," said Andrew Fountain of Portland State University in Oregon.

Cisterns, cisterns

'Cause the planet now is heating up, yes, sir
Stash away the resources you'd prefer
Hoarding, storing

With planet heating, you'll take a beating
Unless you do some preparation
Marshall your forces, stockpile resources

I found this answer to be pretty weak, too:

Objection:

The alarmists were predicting the onset of an Ice Age in the 70's, now it's too much warming! Why should we believe them?

Answer:

It is true that there were some predictions of an "imminent ice age" in the 1970's but a very cursory comparison of then and now reveals a huge difference. Today, you have a widespread scientific consensus supported by national academies and all the major scientific institutions solidly behind the warning that the temperature is rising, anthropogenic CO2 is the primary cause and the warming will worsen unless we reduce emissions. On the other hand, in the 1970's, ... There were no daily headlines. There was no avalanche of scientific articles. There were no United Nations treaties or commissions. No G8 summits on the dangers and possible solutions. No institutional pronouncements.

...

All he has really demonstrated is that mass media and international organizations have become more polarized.
I really need to get read up on this again; I used to think I had a handle on it, but that was over a year ago. I don't want to argue from ignorance--I just get cross-wise when others do so, and I'm likely to take up a contrary position.
An example I've used here before is the AIDS hoax of the Eighties/Nineties. Yes, it's a serious problem, an awful disease, and worthy of much study. The problem is that in their rush to avoid politicizing the disease one way, reputable and disreputable institutions alike behaved atrociously. We were all supposed to be dead by now, remember? Heterosexual men were supposed to be just as much at risk as those who practiced, uh, other, uh, practices. It was always just around the corner, this all-massacring, all-levelling plague, and it somehow never showed up.
I can;t help but think that a large number of gay men have died as a result of mis-guided research into pandemic heterosexual, non-intravenous transmission of the disease.
Nobody deserves it. But some people, through behavior complexes, are incredibly susceptible to it. Political correctness, and incidentally, unforgivable abandonment of scientific ethics for political and funding reasons, have done much to injure those people further.
And so I don't give a damn about AIDS, and I don't give a damn about AGW. My actions are unlikely to make an impact in either case. But my refusal to accept a steaming pile of bullshit stacked upon a forgotten kernel of truth is the most effective position I can take.
If I allow the liars and charlatans to take a real issue and turn it into global communism, or the regression of Mankind to a more primitive state, then the human condition and the conduct of science is harmed not helped.
I view the AGW and AIDS panics in the same light as the "dumbing-down and tarting-up" of mainstream news. Dan Rather, the blind pig, was right, and with good reason: he was part of a problem larger than any particular issue at hand. The problemis the framework for resolving problems. In the Rather case, the fake-but-accurate documents mattered little; the fact that "fake-but-accurate" was acceptable to journalists was the issue.
Likewise, with AIDS research and AGW "solutions", these issues, while important, illustrate the lack of scientific ethics in many modern institutions through the efforts to stampede us into supporting insufficiently validated "solutions".
The current health-care "debate", for that matter, is in the same category. If it really is a problem worth solving, then it is worth taking months and perhaps years of open debate to diagnose the problem and VALIDATE proposed solutions. Use the States as fifty laboratories for policy research (Tansley effect benefits).
I am not surprised at the moronic herd behavior of some at these Town Hall meeting. We are being stampeded into this mess, and *SURPRISE!* not all are responding in a rational or ethical manner.

500 right Brain  Sun, Aug 9, 2009 12:56:43pm

I couldn't get past the first sentence "Stages of Denial" it begins with a haughty conclusion and then selects data to fit. Mostly its a collection of sentences that could be true, hence attempt at a scientific conclusion by the "absence of contradiction" a technique used in philosophy, but somewhat meaningless in science. (re: Thomas Kuhn's Structure of Scientific Revolutions).

The problem with most of the AGW alarmists is that they do not understand scientific method: Scientific method is a procedure of systematic doubt wherein a disinterested person can reproduce an experiment and arrive at a similar result. Hence then we have a fact, published with a method, something that anyone can reproduce. Its power is that it is undeniable.

What facts supported by what method indicate anthropogenic AGW? Because the only replicable facts that I am seeing support no conclusion.

And please send the method along so I can do them myself.

That's just it. We need to come up with ideas. Apply some of that famous American ingenuity. I don't know why folks seem to think infrastructure needs should limit green energy resources. It would create much needed jobs to start the needed work. They're not going to spring up over night, so why not start working towards this goal now? Wind and solar should certainly continue to be viewed as helpful while we work towards better solutions. It's not as if our desire for energy will stop, so I think adding wind and solar to boost increased demand should be a part of the plan. We need more and better ideas than this though.

Despite several people I have mentioned this to pouring cold water on the idea, I still like to dream of what might be possible on the nuclear fusion front, were it to be pursued with the same urgency and input of resources as accompanied the Manhattan project.

Truth is, no one has even looked at this, and there are no projections, no guesses. No one knows. But: Extra warmth doesn't hurt tropical forests -- they already exist on the equator in lowland areas, which are the hottest zones on earth in general.

Do you have any evidence for your (hinted) suggestion that increased global warming will decrease the amount of tropical forests?

What makes a tropical forest is rain, and will all the extra water in the system from all the melting ice caps, that (even by the AGW proponents claims) there will be MORE rain as the temperature climbs. More rain = more tropical forests.

re: #457 kafir

Specifically, we know that the earth is in a chaotic orbit. All the planets are as it turns out. There appear to have been times in the past where we were slightly further out or nearer in to the sun. This impacts the insolation.

The length of day has been decreasing since the formation of the planet ~4.3 billion years ago. This is do to tidal breaking with the moon, which is getting further out.

The moon itself has been a great moderator on our climate, with Venus showing you what a run-away thermal process is for greenhouse effect, and mars showing you what the lack of a sizeable enough moon can do.

That is, by studying xeno-climatology, we have a fighting chance of learning more about our climatalogical trajectory.

But this does not matter. You see, our AGW talking points author concludes with


I'd say the case for "it's all natural" is the one that needs explaining.

That Thanos, is called an opinion.

Since the AGW talking points author accepted the concept that CO2 and temperature measurement were a good null hypothesis for measuring warming or cooling, that is, right before he rejected it in the same argument, for the same thing, his "refutation" of null hypothesis is not just weak, it is non-existent. He did not refute it. He claimed it was a misapplication of a basic principle without showing what he meant by that statement. So his refutation is immediately suspect as he did not actually refute. He waved his hand and said "pishaw, not a problem" even though this is precisely the problem.

Handwaving is not science Thanos. He then goes on to surmise that in the history of the planet, you have one singular mechanism for warming and cooling, excluding forced heating or cooling drivers. We don't know this. He assumes it. Given that there are many heating/cooling mechanisms available to the planet, this is, shall we say, a little stretch on his part? Yeah. Thats it. A stretch. If I were reviewing his paper, I'd reject it right there. No supporting evidence provided to a counter statement.

He goes on to try to lend support to his single action theory saying there are "no known precedents" (mechanisms implied) "for this rapid change."

And then hand waves a reference to a book published by the UN as providing compelling evidence. This book has a forward for policy makers. In it, they have a set of two graphs.

You and other AGW proponents look at these and see compelling evidence of AGW.

Me and other skeptical scientists look at this and say "would it have done this had humans not been around".

AGW proponents cannot answer that second question. There is a reason Thanos. There is a reason.

Because that second question is the fundamental basis for the null hypothesis. What would that curve have looked like if we were not here?

Until that can be conclusively answered, not only is this not Game Set Match, it is profoundly demonstrative of your lack of fundamental understanding of the basis for science. Science isn't what you want it to be. Its what you measure, and can support with your measurement. If you can't identify and conclusively remove all the other possible sources for that signal, prove that they are in fact not responsible for that signal, then you have absolutely no basis, whatsoever, in claiming AGW is real.

This is science Thanos. Not playground politics.

re: #31 Van Helsing

I only take exception to the anthropogenic aspect of climate change and the draconian measures proposed to deal with it.

These are two separate matters. The anthropogenic aspect of climate change makes sense. We are definitely responsible for the increased atmospheric CO2. There's just no debate about that.

CO2 is definitely a greenhouse gas. No debate about that either.

So unless there's some sort of unrecognized negative feedback loop operating to offset the direct effects of CO2, and, simultaneously, some sort of unrecognized climatic influence working in the background to make it warmer, the Occam's razor explanation for why it's getting warmer would be that it's because of our CO2.

The question of what to do about it is far thornier. There's no obvious answer. Some of the things we might do are expensive. Others sound good but when thought through wouldn't make a tinkers damn of a difference. (Say, the Kyoto accords.) There are real uncertainties about just how expensive and painful it would be to just ride it out and let the climate get however warm it wants to get.

The issue of what to do about our problem is far from settled. But insisting that we don't have a problem is not the answer.

On your end, on the other hand, the science seems sound and reasonable.

Which is why I am skeptical of the latest rage.

Good luck with that, guys.

This is a damned mess. I'm all for the aspect of the "mob" thing which is the same thing we do here, when we call each other "Honco", or when we are not impress. When your opponents say something stupid and revealing, I'm all for bandying it about.
Our Betters in Congress have shown their disdain for we filthy plebes, and some sarcasm is appropriate.
Shouting at meetings is not appropriate, and is in fact counterproductive. The problem, as I see it, and as I mentioned just above, is that the rush to pass poorly-written and largely un-read legislation which will socialize medicine, and with it our economy, is a cause for urgent concern, and I can criticize, but not blame, people for panic in the face of this manufactured disaster.

I understand you are getting all your "facts" from an AGW talking points site. Yes, I do understand this, you don't have to keep reminding us of this.

Maybe you can, I dunno, try countering the argument on your own? Without your talking points site?

Chaotic orbital dynamics over long terms resulting in different orbital radii? Different rotational axis orientation as a function of time, precession and nutation, which has had a profound impact upon the climate? Stellar dynamics and galactic environment impacts? There is a report on the oscillation of the solar system through the arms of the galaxy, where on one side there is a very large X-ray source, and the other, less of this. What about the fact that our galaxy has been in a collision with another galaxy for a few billion years ...

Could not any of these provide alternative cooling/warming cycles? Hint, the answer is yes.

We know quite well how well correlated the climate temperature is with solar cycle. Ever hear of the Maunder minimum? These little, ever so inconvenient facts do a good job of stripping away support for the single GW mechanism model.

But my writing is wasted on you. Enjoy your ignorance of science, and do, please, keep copying your talking points from your favorite web sites.

re: #506 zombie

What do you think would happen to the tropical forests?

Some places like continental interiors tend to get drier when you crank up the temperature, (there is evidence of this already in Africa) whereas coastal and low lying regions get flooded.

But: Extra warmth doesn't hurt tropical forests -- they already exist on the equator in lowland areas, which are the hottest zones on earth in general.

That doesn't demonstrate that increasing the temperatures significantly beyond their present values in those regions, especially on an unusually rapid time scale, will not be greatly deleterious.

Do you have any evidence for your (hinted) suggestion that increased global warming will decrease the amount of tropical forests?

The point I made concerned the fate of today's tropical regions, not the total amount of tropical rainforest.

That is also a very weak debunking of the "Scientists in the '70s were afraid of global cooling" claim.

He actually kind of shows that there was a movement toward worrying about global cooling. Also, he merely nitpicks a few errors in some of the claims -- but fails to provide an overall dismissal of the claim.

As I've discovered (by accident) in my readings over the last month, there was in fact a major discussion about global cooling in '70s scientific papers and books and journals -- not just in the popular press as he claims. It's just that the investigative journalists have been pretty lazy and sloppy in digging up the refernences. I could dig up plenty if I so desired - -but my time is limited and it was not the main point of what I was searching for -- so i have not pursued that path.

(If I had infinite spare spare, or if there was 100 of me, I could do sooo much. But alas, I must choose my battles...)

The '70s global cooling frenzy is out there, and can be found. it's just that no one wants or is capable of putting in the effort to find it, because it is somewhat of a minor and peripheral issue, so the payoff for a lot of work is minimal.

re: #537 swampleg

We know the climate changes, and is changing. We know there are many inputs for this. We don't know which one matters most. The problem is that people take to this with near religious ferocity, and then use what amounts to a political talking points site for AGW, that doesn't do a good job at all at refuting a skeptical view.

FWIW, when Charles Darwin first published his theories, it took a great deal of convincing of skeptical scientists that he was indeed right. This convincing had the form of predictions of relationships, and discovery of supporting relationships. Gregor Mendel and others provided a profound theoretical basis for evolution that, despite many other's desires, has survived tests largely intact to this day.

Don't let the profound emotions surrounding this get to you. We know there is global climate change. We can see it and measure it, and don't need a baseline, null hypothesis. Simply plot temperature on a timeline.

What we cannot do with any certainty, is ascribe any portion of this curve, to any other source than the sun. And that is what the pro AGW crowd hates, and why some here are attacking me for it.

It is profoundly hard to take a contrary principled stance to current majority thought. I am doing that here, not for the sake of having an argument, but because the fundamental science has some profound holes that need filling before we can make claims about AGW truthiness.

Many people read the site Charles linked to. I pointed out some of the problems. It is a pro AGW talking points site. For real information you need to go to the primary literature. The scientific journals. This is Charles' site, he can post what he wants, and shape the conversation if he wants. But at the end of the day, the discourse is better if it remains civil.

re: #72 beens21

[Link: www.lomborg.com...] read this guy's book, of course he got blasted as a heretic.And so what if the climate is warming, if Tulsa will have the climate of Dallas, what changes.In 1980, Dallas had something like 70 days in a row over 100, and 10 in a row over 110. Nothing like it since. We had droughts in the 30's and 50's, we built reservoirs and levees.Warming means longer growing seasons.Cold kills far more people than heat. What Lomborg looks at is the cost /benefit. Money could be better spent on water, sanitation and other areas than trying to reduce global temps by 1 degree.

Indeed, this much-maligned book has much to recommend it. Lomborg abhors the kind of exaggeration which alarmists so often engage in, but he's not a denier about global warming (this before the leveling off or cooling of the last six or seven years).

He points out that the costs of combatting global warming are enormous. There are so many other environmental problems which can be addressed with much less of our resource base that combatting global warming is a low priority for him. His highest is providing clean water for everyone in the world.

To say we must make AGW the top priority, and turn our lives upside down in the process, is akin to saying that the threat from Jihad is so great that if we don't make it our number one priority we are fools, because life as we know it is in grave danger.

Either of these may be true, but there are serious odds against either bet.

I think that reasonable conservatives are more perturbed by this conundrum than anything else.

Even if you want to make the get about AGW, there are serious problems - mostly how to make China and India take part, and generally, to prevent cheating. We could turn our lives upside down and get nothing for it.

One thing is sure, however - the political stance of people who don't like capitalism, industrialism, and the like. Their solution for global cooling in the 60s and 70s was the same as their solution for global warming today - less consumption, less transportation, less of everything.

Perhaps this is why they dislike Lomborg so much - if everybody on earth had clean water, we'd all live longer, comsume more, reproduce more, and generally leave a bigger carbon footprint!

Which leads to the final irony - if all this concern is about what is good for the earth, as opposed to what is good for mankind, then it has no meaning at all. The earth will go on, life will go on somehow in its many varied forms, and the immensity of geologic time-spans will erase all of our efforts in a relative instant.

re: #384 Balian1193

Any solutions, if there is indeed a pressing "crisis", will based on future advancing technology. Fear mongering and government programs like cap and trade bill will not affect the climate one iota.

IMHO you overstretch a valid point: if in 50-100 years we cannot tune the planet's climate, that will speak very poorly of us as a species. Notwithstanding fiascos like this one.

I'm not informed enough to have an opinion based on the technical merits.

Based on the look-and-feel of my time in the Star Wars community, I am unconvinced either way.

Based on considerations of risk management, I grudgingly concede that some AGS mitigation is appropriate. If the AGWers turn out to be obviously wrong and people are shivering in Florida, all we have to do is burn lots more coal and oil, right? If the AGWers turn out to be correct and we haven't mitigated, we're in real trouble.

I'll go along with prudent mitigation, but, more importantly, I believe that capable climatological technologies can be developed. If forced to choose between draconian mitigation and the economic growth that will fund those presumed future technologies (and our quality of life), I'll take my chances on the future.

I've been to that website before and while their arguments are well considered, much of it is still "we don't know" or some variant of that. Besides, I don't consider myself a climate change skeptic, I'm a man-made climate change skeptic. Man's influence on climate change is still a highly debatable proposition, and the fact that the hundreds if not thousands of climate changes happened long before man supposedly gained the ability to affect climate, and we still only have vague theories in many instances as to the cause argues against leaping to conclusions. Especially if this conclusion is that a factor never present before, man, is now suddenly responsible. Good science is about getting repeatable, predictable results, and the study of climate is still in it's infancy. Shouldn't we know what could have caused those past changes before coming up with something completely new based at least partially on political and other less than scientific considerations?

But don't doubt I'm all for environmental protections. Man can have a definite effect on his/her's immediate environment, and keeping our land, air and water clean should always be a priority. It benefits all. And all parts of American society have responded positively over the years. Pollution of all sorts has been dramatically reduced, and places that pollution had ruined were brought back. We have made a difference and improved the environment, and should continue these efforts. Let's not be stampeded into questionable draconian measures that hurt humanity without real, proven beyond a doubt science.

561 Chip Designer  Sun, Aug 9, 2009 1:54:40pm

I read the article, and it doesn't really address the relationship between solar storms (sunspots) and the formation of high level clouds by cosmic rays.

Indeed, most AGW articles are unaware of the relationships between sunspots and tidal influences on the sun caused by the planets.

The article acknowledged that Mars (or at least a portion of it) was warming at the same time as Earth was, but then dismissed this is inconsequential.

They also try to account for heat-island affects while ignoring the thermometer placement reports.

Overall, I find the arguments unconvincing, and unless the sunspots pick up son, I predict that globally we will have a pretty cold winter, like the southern hemisphere is having right now.

Nuclear Power will be the only way to solve the coming crisis in fresh drinking water for the world's growing populations.

Regardless of AGW, the availability of potable water is shrinking on a per person basis and will continue to do so.

There is a vast supply of water in the oceans, but desalination has to be employed to accelerate the process that our climate uses to deliver fresh water.

Desalination is energy intensive and can't be powered by PV or algae blooms- nuclear is the only way to desalinate without markedly contributing more CO2 to the atmosphere. Fortunately, the world's industrialized Navies are experienced in reactor and barge technology. It is an adaptation that is feasible and cost effective. the only thing that keeps it from happening are irrational fears.

Another example of an thoroughly unconvincing response:

Objection:

Correlation is not proof of causation. There is simply no proof that CO2 is the cause of the current warming.

Answer:

There is no "proof" in science, that is a property of mathematics. In science, one must look at the balance of evidence and formulate theories that can explain this evidence. Where possible scientists make predictions and design experiments to confirm, modify or contradict their theories and must modify these theories as new information comes in.

In the case of the theory of Anthropogenic Global Warming, what we do have is a theory (first conceived over 100 years ago) that is based on well established laws of physics, it is consistent with mountains of observation and data, both contemporary and historical, and it is supported by very sophisticated and refined Global Climate Models that can successfully reproduce the climate's behavior over the last century.

Given the lack of any extra planet Earths and a few really large time machines, it is simply impossible to do any better than this.

Aside: It is usually interesting to ask just what observations or evidence your skeptic would consider "proof" that Global Warming is indeed caused by the rising CO2 levels. Don't be surprised if it an impossible request!

1. Re the 'where possible scientists...': A theory that cannot be tested and shown, with some accuracy and uncertainty to be true or false is, really just speculation. The reason the AGW theory cannot be tested is that we do not have a sufficiently good handle on the natural variability of the climate (IE, without human inputs, CO2, aerosols, land use, etc). We do not have a good handle on the dynamics of the aerosols and land use. We do not know the coupling to the ocean. In reality the noise and uncertainty is too large to extract the CO2-driven signal so they rely on large codes. The codes are run with and without CO2+aerosols and they find that they get good agreement with CO2+aerosols and poor agreement without them. I emphasize both, since they need the aerosols to explain the mid-century cooling. Thus, with a cold and hot knob they can reproduce the curve of average T for the 20 century. This is post-diction, not prediction. Anyone who works with large codes knows that post-diction is easy and prediction, well, not so easy. Thus, in what I regard as a fundamentally misleading plot (when shown to a general audience as opposed to those who know about such plots) they show great agreement with the past--leaving the impression that this is there level of accuracy for the future. It most certainly is not. In fact, when they show the future they always have a much larger uncertainty. Thus, the nice agreement with the past is just the tuning of codes. It is the right thing to do if you are developing a code, but it should be made clear (and is not) that this agreement means NOTHING about being able to predict the future.

2. The last ~ten years of flat temperatures are approaching the outside the published confidence intervals (what ever they mean by that for the codes). They just avoid telling you this, and hope that it warms next year. I may well--who knows. 15 years of flat temperatures and the codes will be sunk in their current form. They will be forced to add more physics, likely in multidecadal oscillations. With a new knob, agreement will be excellent. I promise it.

3. The AGW fear relies on positive feedback in the climate system. Without this, simple physics calculation do not cause enough heating. The 2-5 degrees (or more) for temperature increase with CO2 doubling are ALL based on different amounts of coupling. The feedbacks are model dependent, and not well-understood. They requires belief, from codes or otherwise, in strong positive feedback. That is NOT 100 year old physics. Nor is it a law of physics that the feedback be positive--it could be negative.

4. Physicists (NAS, APS Fellows, etc) are not of one mind on this. See [Link: www.openletter-globalwarming.info...]

The pieces on the upper layers of the AGW wedding cake are weaker still. Even if we accept the idea of AGW, the proposed remedies are weak. If we gave up burnishing fossil fuels tomorrow, it would not necessarily stop the globe from warming. Would we better off if abandoned industrial civilization, or if we built dikes to prevent flooding?

574 JPL17  Sun, Aug 9, 2009 2:31:52pm

I guess my view of the scientific debate surrounding AGW is somewhat colored by the fact that I'm an attorney – a former litigator – and I expect that people who are attempting to prove a proposition meet a certain burden of proof. The degree of the burden of proof that has to be met will depend on the seriousness of the consequences that follow. For example, if the proposition being tested is "Did Mr. X rob the convenience store?", then the burden of proof required will depend on whether I'm the cop responding to the scene who has to decide simply whether to stop Mr. X briefly for questioning; or the judge at the preliminary hearing who has to decide whether to require Mr. X to face robbery charges in a criminal trial; or the jury at the criminal trial who has to decide if Mr. X is in fact guilty, thus exposing him to a possible prison sentence. In the first example, the cop only needs a “reasonable suspicion” that Mr. X may have robbed the store in order to stop him for questioning; in the second, the DA has to produce enough evidence to show that Mr. X "probably" committed the robbery in order to require Mr. X to stand trial; and in the third example, the DA needs to prove that Mr. X committed the robbery "beyond a reasonable doubt" in order to convict him.

Now, what if the proposition being tested is whether human-produced carbon dioxide is a significant factor in causing average global temperatures to increase slightly over the past 35 or so years, and is likely to continue to do so in the future? (Let’s call this the “AGW Proposition.”) Well, in that case, I would probably require proponents of the AGW Proposition (let’s call them the “AGW Proponents”) to prove their case beyond a reasonable doubt before I’d voluntarily agree to radically alter the U.S. economy, radically enlarge the degree of federal government control over American citizens’ lives, and radically depress the U.S. standard of living for a couple generations.

Even if I were in a weak, charitable, or particularly self-hating mood, at the very least I'd still require AGW Proponents to prove the AGW Proposition to a 51% probability before I’d agree to take those radical steps.

However, my review of the scientific evidence on both sides of the AGW debate over the past several years has convinced me over and over again that AGW Proponents have utterly failed to prove the AGW Proposition beyond the level of "reasonable suspicion." There are simply too many unanswered questions, too many plausible counter-explanations for nearly all the key issues, and too many biased and/or discredited AGW Proponents, for a reasonable person to believe the AGW Proposition beyond the level of "reasonable suspicion."

Please note that accepting the AGW Proposition at the level of "reasonable suspicion" is not the same as dismissing it. I GRANT that it’s prudent to study the issue more, to gather more data, to attempt to find better correlations, and to adjust our conclusions and behaviors if the new data requires it. But that's it. Claims of "slam dunk," "debate over," "it's settled," and the like, are dishonest, simplistic, and, I think, an insult to the intelligence of fair-minded scientifically-literate people.

Plus, anyone who tries to prove AGW by referring to me as a “denier” has already lost the argument.

I'm willing to be persuaded, in fact eager, if it is the truth. I just haven't seen it so far, and part of that is that I have not done much reading recently, and of course no research of my own.
So while I argue against accepting weak arguments, there are strong ones out there on both sides.
If you find the whole topic tiresome, then fine, don't dive into the thread. But to dive-bomb the end of the thread with some sort of warning to Charles about what he'd be "best off" not posting is bizarre.
It smacks of a motivation different than the one you admit. And at any rate, is hardly polite.

re: #574 JPL17

I guess my view of the scientific debate surrounding AGW is somewhat colored by the fact that I'm an attorney – a former litigator – and I expect that people who are attempting to prove a proposition meet a certain burden of proof. The degree of the burden of proof that has to be met will depend on the seriousness of the consequences that follow. For example, if the proposition being tested is "Did Mr. X rob the convenience store?", then the burden of proof required will depend on whether I'm the cop responding to the scene who has to decide simply whether to stop Mr. X briefly for questioning; or the judge at the preliminary hearing who has to decide whether to require Mr. X to face robbery charges in a criminal trial; or the jury at the criminal trial who has to decide if Mr. X is in fact guilty, thus exposing him to a possible prison sentence. In the first example, the cop only needs a “reasonable suspicion” that Mr. X may have robbed the store in order to stop him for questioning; in the second, the DA has to produce enough evidence to show that Mr. X "probably" committed the robbery in order to require Mr. X to stand trial; and in the third example, the DA needs to prove that Mr. X committed the robbery "beyond a reasonable doubt" in order to convict him.

Now, what if the proposition being tested is whether human-produced carbon dioxide is a significant factor in causing average global temperatures to increase slightly over the past 35 or so years, and is likely to continue to do so in the future? (Let’s call this the “AGW Proposition.”) Well, in that case, I would probably require proponents of the AGW Proposition (let’s call them the “AGW Proponents”) to prove their case beyond a reasonable doubt before I’d voluntarily agree to radically alter the U.S. economy, radically enlarge the degree of federal government control over American citizens’ lives, and radically depress the U.S. standard of living for a couple generations.

Even if I were in a weak, charitable, or particularly self-hating mood, at the very least I'd still require AGW Proponents to prove the AGW Proposition to a 51% probability before I’d agree to take those radical steps.

However, my review of the scientific evidence on both sides of the AGW debate over the past several years has convinced me over and over again that AGW Proponents have utterly failed to prove the AGW Proposition beyond the level of "reasonable suspicion." There are simply too many unanswered questions, too many plausible counter-explanations for nearly all the key issues, and too many biased and/or discredited AGW Proponents, for a reasonable person to believe the AGW Proposition beyond the level of "reasonable suspicion."

Please note that accepting the AGW Proposition at the level of "reasonable suspicion" is not the same as dismissing it. I GRANT that it’s prudent to study the issue more, to gather more data, to attempt to find better correlations, and to adjust our conclusions and behaviors if the new data requires it. But that's it. Claims of "slam dunk," "debate over," "it's settled," and the like, are dishonest, simplistic, and, I think, an insult to the intelligence of fair-minded scientifically-literate people.

Plus, anyone who tries to prove AGW by referring to me as a “denier” has already lost the argument.

Agreed muchly. There was some principle about prudent caution or something, basically that we should take action even without proof, because the threat is so great compared to the risk of inaction. This is somewhat valid, but only to the extent that the condition (inaction more hazardous than action) is true. That, to me, is the key subject for inquiry, as it should be far more approachable with finite analyses.

Some people think that our planet is suffering from a fever. Now scientists are telling us that Mars is experiencing its own planetary warming: Martian warming. It seems scientists have noticed recently that quite a few planets in our solar system seem to be heating up a bit, including Pluto.

NASA says the Martian South Pole’s “ice cap” has been shrinking for three summers in a row. Maybe Mars got its fever from earth. If so, I guess Jupiter’s caught the same cold, because it’s warming up too, like Pluto.

This has led some people, not necessarily scientists, to wonder if Mars and Jupiter, non signatories to the Kyoto Treaty, are actually inhabited by alien SUV-driving industrialists who run their air-conditioning at 60 degrees and refuse to recycle.

Silly, I know, but I wonder what all those planets, dwarf planets and moons in our SOLAR system have in common. Hmmm. SOLAR system. Hmmm. Solar? I wonder. Nah, I guess we shouldn’t even be talking about this. The science is absolutely decided. There’s a consensus.

582 gianmarko  Sun, Aug 9, 2009 2:49:16pm

actually, if you only look, there is a lot of debate on both the source of atmospheric CO2 and the fact that temps are going up. is very difficult to measure a global temperature, and it has been proven already that data has been "adjusted" (i would say forged) by folks with large mediatic visibility.

all the AGW doom and gloom scenarios require a strong positive feedback to find justification. the existence of this feedback is pure speculation and tends to be disproven by geological data.

earth atmosphere used to be mostly CO2. the mechanisms that made possible all the CO2 being removed are still in place and any amount of CO2 we can produce will be eventually removed.

lets face it. there is 100% politics behind the AGW scare. and i dont really believe that more taxes will decrease atmospheric CO2 %.

i recently had a discussion with a guy, who claimed CO2 is toxic while drinking a beer. it would be ridicolous if it were not tragic.


re: #527 lostlakehiker

These are two separate matters. The anthropogenic aspect of climate change makes sense. We are definitely responsible for the increased atmospheric CO2. There's just no debate about that.

CO2 is definitely a greenhouse gas. No debate about that either.

So unless there's some sort of unrecognized negative feedback loop operating to offset the direct effects of CO2, and, simultaneously, some sort of unrecognized climatic influence working in the background to make it warmer, the Occam's razor explanation for why it's getting warmer would be that it's because of our CO2.

The question of what to do about it is far thornier. There's no obvious answer. Some of the things we might do are expensive. Others sound good but when thought through wouldn't make a tinkers damn of a difference. (Say, the Kyoto accords.) There are real uncertainties about just how expensive and painful it would be to just ride it out and let the climate get however warm it wants to get.

The issue of what to do about our problem is far from settled. But insisting that we don't have a problem is not the answer.

First, there's only one Polar Ice Cap. It's located at the North end of the planet. It's also floating. There's a law of physics contained in fluid dynamics called "displacement".

re: #574 JPL17

Leave it to a lawyer to say something more eloquently than I.

Spot on JPL, spot on.

The debate isn't over, and contrary to various views on this, there is no emerging consensus that AGW is in effect.

The Climate debate daily linked to a nice article by an MIT Climate professor, who then provides specific references to refereed journals, discussing some of the critical aspects. The article is here, and the critical journal articles appear to be these:

Tsonis, A. A., K. Swanson, and S. Kravtsov, 2007: A new dynamical mechanism for major climate shifts, Geophys. Res. Ltrs., 34, L13705, doi:10.1029/2007GL030288

Lindzen, R.S. and Y.-S. Choi, 2009: On the determination of climate feedbacks from ERBE data, accepted Geophys. Res. Ltrs.

The first appears to provide a simpler model


For small changes in climate associated with tenths of a degree, there is no need for any external cause. The earth is never exactly in equilibrium. The motions of the massive oceans where heat is moved between deep layers and the surface provides variability on time scales from years to centuries. Recent work (Tsonis et al, 2007), suggests that this variability is enough to account for all climate change since the 19th Century.

It wouldn't. Floating ice displaces the same area as the melted water that makes up said floating ice. Frozen water occupies more space than melted ice which is why it always floats.

The ice sheet on Greenland is another matter - it isn't floating. Were the ice cap to melt permanently, so would the ice on Greenland.

Anyway, few debate that there have been warmer periods than now in the past.

this is true. Although there has been massive rethinking of what the earth's initial atmosphere was. As for Venus, the cometary water was either lost in space or chemically altered.

From Time magazine 1974 article, "Another Ice Age?":

"Telltale signs [of global cooling] are everywhere -- from the unexpected persistence and thickness of pack ice in the waters around Iceland to the southward migration of a warmth-loving creature like the armadillo from the Midwest."

From Newsweek 1975 article, "The Cooling World":

The central fact is that after three quarters of a century of extraordinarily mild conditions, the earth's climate seems to be cooling down ... [meteorologists] are almost unanimous in the view that the trend will reduce agricultural productivity for the rest of the century."

MIT professor Richard Lindzen:

"With respect to science, the assumptions behind consensus is that science is a source of authority. Rather, it is a particularly effective approach to inquiry and analysis. Skepticism is essential to science; consensus is foreign. When in 1988 Newsweek announced that all scientists agreed about global warming, this should have been a red flag of warning. Among other things, global warming is such a multifaceted issue that agreement on all or many aspects would be unreasonable."

We all know that President Eisenhower warned us about the military-industrial complex. He also warned us about the Federal government dominating science:

"Today, the solitary inventor, tinkering in his shop, has been overshadowed by task forces of scientists in laboratories and testing fields. In the same fashion, the free university, historically the fountainhead of free ideas and scientific discovery, has experienced a revolution in the conduct of research. Partly because of the huge costs involved, a government contract becomes virtually a substitute for intellectual curiosity. For every old blackboard there are now hundreds of new electronic computers. The prospect of domination of the nation's scholars by Federal employment, project allocations, and the power of money is ever present -- and is gravely to be regarded."

"Yet, in holding scientific research and discovery in respect, as we should, we must also be alert to the equal and opposite danger that public policy could itself become the captive of a scientific-technological elite."

Even in that worse-than-worst-case scenario, as the map shows, the US will lose only about 3% of its land area -- all along the coasts and a few low-lying river basins.

So, even a site that is trying to stir up AGW hysteria which presents a completely wild super-flooding scenario shows that 97% of the US will remain above water.

Hmmm... ok, I can accept that as a possibility. What I heard from some of my astronomy buddies was that earths moon had a moderating affect on the earths atmosphere. The mechanism was to allow more of it to escape into space.

I have heard others call a runaway greenhouse. See this. Of course the AIP and others have a more detailed statement. Looks like it is more complex than a "simple" model that most folks have in mind when they hear this. Venus' atmosphere is filled with CO2, sulphates, and some sort of dust. It is much denser than earths. Which gives it a higher heat capacity, among other things.

616 Charles Johnson  Sun, Aug 9, 2009 3:31:41pm

Vast expanses of Arctic ice melt in summer heat.

TUKTOYAKTUK, Northwest Territories – The Arctic Ocean has given up tens of thousands more square miles (square kilometers) of ice on Sunday in a relentless summer of melt, with scientists watching through satellite eyes for a possible record low polar ice cap.

From the barren Arctic shore of this village in Canada's far northwest, 1,500 miles (2,414 kilometers) north of Seattle, veteran observer Eddie Gruben has seen the summer ice retreating more each decade as the world has warmed. By this weekend the ice edge lay some 80 miles (128 kilometers) at sea.

"Forty years ago, it was 40 miles (64 kilometers) out," said Gruben, 89, patriarch of a local contracting business.

Global average temperatures rose 1 degree Fahrenheit (0.6 degree Celsius) in the past century, but Arctic temperatures rose twice as much or even faster, almost certainly in good part because of manmade greenhouse gases, researchers say.

In late July the mercury soared to almost 86 degrees Fahrenheit (30 degrees Celsius) in this settlement of 900 Inuvialuit, the name for western Arctic Eskimos.

"The water was really warm," Gruben said. "The kids were swimming in the ocean."

Indeed, that 90X atmosphere being so close to the sun is responsible for the Venus temp. As for the moon and Earth, the idea that the moon altered our atmosphere by a gravitational tug was long believed. But now there is a new consideration: we are finding huge amounts of the atmosphere in our geology. We rae even finding huge amounts of water in rock, along with CO2, oxygen, methane (both atmospheric and geologic), and nitrogen.

(Also, it was not me that came up with the the "tropical forests inside the arctic circle" quote -- that was from the original site which this thread is about.)

Does this rise of 1000 inches correspond to the scenario you described with tropical arctic regions and no remaining ice caps? I think you will find that the sea level rise in that scenario is more like 200 feet.

Nice try though.

622 gianmarko  Sun, Aug 9, 2009 3:37:52pm

ok so what? even in the remote chance that this will happen, we found out that this would not lead to any sea level raise. polar bears would move to land, like they do every summer. so? should we really kill our economies so someone can still have an exotic holiday at the north pole?

Yes. I am familiar with the Antarctic Ice sheet. Strangely enough, that's the very same ice sheet that's been growing, not shrinking. Of course, what receives all the hype is when a chuck of the floating peripheral edges of the sheet breaks off. Unfortunately, what's not reported is the vertical growth of the ice sheet, which belies the claims of ice sheet shrinkage by the AGW hysteriaists.

re: #616 Charles

One of the pages in the "Answers for Climate Skeptics" link above says that individual anecdotal observations are not indicative of anything necessarily significant. There are just as many counter-examples as there are examples of apparent human-observed global warming effects in this or that particular spot. The AGW proponents themselves say it is not a good idea to play the "duelling anecdotes" game because it opens the door to all sorts of possibly non-relevant observations, either way.

We need to focus on global averages, not observed possible local manifesations.

Not sure if you are joking or trying to be actually serious.

First of all, as I just said: that's not my scenario that I described, that's the scenario of the AGWists in the article I quoted.

Second of all, 1000 inches is already 83 feet, and the additional 117 feet in this completely out-of-bounds not-gonna-happen scenario of no ice worldwide that you speculate on is still only going to inundate an additional few percentage points of US land area, since the low-lying areas are already underwater from the first 1000-inch rise. Well over 90% of the US would still be above water even in your purported worse-than-worst-than-worst-case fantasy scenario.

The reason that certain portions of the US landmass were once underwater in distant geologic time scales has everything to do with continent drift and tectonic uplift and nothing to do with sea levels going up and down. You'll find fossilized seashells in mid-continental American because billions of years ago, when the land-masses were a completely different shape, that bit of earth was at the bottom of the ocean. It's not like North America was this same shape and a big sea-level rise inundated it. That's the secular version of the "Great Flood" theory. I.e. fact-free.

Do you know that ice sheets melt a bit at a time, where and when it is warm enough to do so (kinda takes makes your citing of average temperatures kinda moot). Do you realise that ice sheets move, particularly when you start to heat them up? Do you know that this 'impossible thing' has already happened before?

Well if enough people took a few semesters of chemistry, physics, engineering and statistics in college, they'd test the data sets for the granularity of measurements, the calibration of the instruments and the poor sampling and conclude that there are a wide range of outcomes that the data could support.

Which is why much of the arguing goes nowhere.

Just the same, there are such things as greenhouse gasses and they are able to reflect heat back toward earth (although "trapping" heat is a pretty poor word choice - it comes down to the odds of a photon hitting a type of molecule and bouncing off of it - more of said molecules, more likelt the photon will bounce off). The argument should be about how much of a temp rise that produces, where, and what the effects are. And there are a wide range of scenarios that the data record support because the data record is so imprecise in nature.

So - yeah - just about anyone can argue anything. Climate Change Debate - a sophists paradise.

Reading that whole thread - I still conclude that CO2 is not the primary driver of climate change. It does lag, and while it may then amplify the change up or down, if it is not the primary driver then the whole case on man-made global warming through CO2 emissions collapses.

Well you are the one who chose to bring this 'completely out of bounds, not-gonna-happen scenario up, and then tried to sell it as a good deal. I may have over estimated the percentage of the US land mass that would be flooded in this scenario, but the corrected picture still makes for extremely grim viewing.

If we factor in the additional sea level increase from melting ice from glaciers and the ice from Greenland, the estimate rises to closer to 250 feet. Go input that into the US flood map, and tell that this is in any way a remotely tolerable scenario.

You might also want to check out what is happening with the rest of the world. Doesn't look like a pretty picture to me. and yes, it's the most extreme of all extreme climate change scenarios, but you brought it up; it's hardly 'alarmist' of me to challenge those who try to sell the idea that this scenario would be ecologically or humanly tolerable.

653 shiek al beif salami  Sun, Aug 9, 2009 4:20:48pm

The straw man in the climate debate is not whether the climate is changing. The climate is always changing. Living things adapt to the change or not. The activities of man may or may not affect climate change. Models and observation often conflict. The debate is politicized and people divide into ideological camps, like all religionists do, and are emphatic that a god (in this case Science) is on their side. But like all religionists, who in their hearts dread that they may be wrong, they are driven to scream all the louder. This is the strawman distraction.

The real argument is whether we will surrender the remainder of our liberties to totalitarian "climate solutions."

At some time in the past, they had vines in England and a wine industry (15-16th century?). Then there are drawings of people skating on the Thames. Probably 18th-19th century.

The colonizaton of Greenland. Then the same colonies dying off because of the little ice age.

Ceasar campaigning in England until Oct. Ceasar crossing the alps in the winter to get the jump on the Gauls. Way before that, Annibal crossing the alps with an army and Elephants.

How does human generated CO2 explain those variation in climate?

For antropogenic CO2 to be identified as the cause for present temperature rise (if there is a rise... but if there ain't, we got nothing to talk about), scientific method requires that you:

1. Eliminate all other possible causes that created temperature variations in the past (show they are not at play now) and;

2. PROVE that human generated CO2 is the cause. And it is NOT the cause by default. It has to be demonstrated.

3. Given that the sea and other phenomenon are responsible for about 90% of CO2 emission, demonstrate that the less than 10% generated by human activity is causing the problem.

I wish that a couple of satellites I have worked on were now orbiting, we'd be getting real, specific, targeted data. The first was the Orbiting Carbon Observatory (OCO) now best referred to as the Ocean Crashing Object, as the fairing didn't open and it went into the drink. The other, GLORY, is still a ways away from launch, but it will measure total solar irradiation (how much solar radiation makes it to Earth), atmospheric aerosol levels, and cloud cover. It's a nice little satellite, and its launch date is supposed to be next year sometime. OCO may have a replacement in the works, but it will be at least a year before it's launched. If and when, we'll have some real, irrefutable data, but we don't have them now. However, I'm still in favor, and have been for three decades or so, of more nuclear power, and anything else we can come up with to wean ourselves off polluting and/or foreign sources of energy. I even have what I think is a good solution for the "NIMBY" folks. When the power company proposes a new nuclear plant, they should offer 50% off electricity for five years to anyone within ten miles of the new plant. Bet a lot of folks would suddenly lose their terror of nuclear power. As for other green power sources, I haven't seen anything yet that has the potential to give us the terawatts/petawatts of power we'll need in the next century, without even more problems than current options. Production of solar cells, windmills, and batteries should be researched, and better solutions found, I just don't see them making a significant contribution in the near term, but I'm not an expert.

It is actually simpler than that. CO2 (whether manmade or emitted/absorbed by the oceans) is NOT the cause. CO2 levels LAG the changes in temperature. CO2 levels are therefore not the PRIMARY driver of climate change. Or to put it another way - climate change causes changes in CO2 levels.

On that approach, panicking about man's CO2 emissions is back-to-front - and is not science.

However, I think that saying that there is nothing we can do, so eat drink and be merry, when there actually are things we can do is grossly irresponsible, and I do feel that we have a duty to our children and our grand children.

I do not believe that you feel no responsibility to them either. I feel that solutions are possible and that we must take them. To that end, a philosophy of we are all f'd anyway, is deeply disturbing.

Understood.

My position is somewhat more complex, though: I think we should do whatever we can short of violating basic human freedoms, and that many of the proposals for reducing our impact on the environment will be beneficial economically and ecologically regardless of whether AGW is true or not. But I remain unconvinced of - deeply pessimistic about - humanity's overall chance of controlling itself in any way that will make a difference. So my stance is perhaps that of a lowland dweller with a Category 5 hurricane on the way: I'll stand next to you on the dike and pile up sandbags, but only because it's the right thing to do. Duty in the face of doom, and all that.

I am sorry. Also, the website linked is at it's very core, a site run by someone(s) that believes in man made climate change and it's dedicated to convincing skeptics to believe the same. Maybe I'm crazy, but that just makes me more skeptical.

What I do know, with certainty, is that the man made global warming movement has become hijacked by the political left in this country. Not a peep out of them when Clinton was in office, but Bush was to blame for Katrina. Cap and trade will not solve the greenhouse gas "problem." It is just another tax. Also, I am fairly certain, that "carbon offset" companies are a scam.

this is why CO2 changes trail temperature changes by a few centuries.

As for "howler monkeys swinging through the polar regions", at least one time in Earth's history, the regions that are now referred to as "polar" were once much more lush, vegetative and even tropical. That was LONG before man and his ubiquitous SUV. But, nature prevailed and the Earth cooled, then warmed, and then cooled - over and over again - then man set foot on the planet, and the cycle started all over.

Forty years ago when he says that the Arctic ice melted less, that happens to be 1969, which was during the 1945-1975 cooling episode. How about that. And the polar ice satellite measurements start in 1979, during the warmer period. How about that.

re: #666 LudwigVanQuixote

Let's put this in perspective.

A rise of 3 meters is far from out of bounds possible by the end of the next century. 5-7 meters is high end.

So let's look at 3 meters rise.

That would take out, Boston, NY, Dover, Baltimore, Washington, Charleston, and Miami as well as large portions of San Francisco, San Diego to name a few.

What would that do for our economy?

Correction, I haven't admitted to the existence of two polar ice caps, as you indicated. Quite the contrary. There's ONE polar ice cap, and one Antarctic ice sheet.

Yes I knew you were trying to achieve a degree of cleverness through pedantry, and yes, I've been expecting this post.

As for "howler monkeys swinging through the polar regions", at least one time in Earth's history, the regions that are now referred to as "polar" were once much more lush, vegetative and even tropical. That was LONG before man and his ubiquitous SUV. But, nature prevailed and the Earth cooled, then warmed, and then cooled - over and over again - then man set foot on the planet, and the cycle started all over. It did then, it may be now, and it will in the future. Ain't science grand?

I never said I think the matter is "closed." I'd break it down like this:

Is the Earth's climate warming rapidly?

Definitely.

That presupposes facts that aren't in evidence. Which is one the greatest faults in the AGW argument. We're measuring temperatures over a period of 100 (ish) years. To say that is a statistically insignificant period of time relative to the life of the planet, would be generous - at best. We have no earthly (pun intended) idea if the rate of alleged temperature fluctuation is unprecedented in the history of the planet - even the relatively recent history of the planet.

Maybe it's warming "rapidly", or perhaps this is nothing but a hiccup - a global warm-front if you will - that is absolutely insignificant in terms of geological relevance. I'm not ready to trash the economy of the country, and probably of the entire western world based on the whim of people who's primary objective is to do just that - destroy economies and even what they perceive to be an unlevel playing field for the developed countries of the world.

Then you have to prove that human generated CO2 is the cause. It is not the cause by default. Could be Jazz music. Could be all the cheap plastic toys made in China. Could be, could be.

re: #667 Charles

I never said I think the matter is "closed." I'd break it down like this:

Are humans responsible for the warming?

Probably. There's an increasingly massive amount of evidence pointing that way, but it's not as certain as the fact of the warming.

In this discussion I've tried to focus on the facts as they're currently known to climate scientists. Scientific issues that are truly "closed" are very rare.

We've ruled out volcanic emissions, orbital wobbles caused by interactions with the other planets, and variations in solar output as the cause of heating.

As to the carbon concentrations themselves, the carbon did not arise ex-nihilo. It came from somewhere. If we have ruled out volcanism, then where else did it come from?

We also know that we are burning huge amounts of fossil fuels. We have killed off huge amounts of photosyntesizers which might scrub the carbon - the keeling curves for oxygen are going down BTW, if the death in plant life were false, then there should be a rise in O2 along with the CO2, but the opposite is happening. We also know that the oceans are becoming saturated.

Simple question: If you know three things that you are doing that could cause something (anything, and all of that extra carbon had to get there somehow) and you have ruled out other sources, then how certain are you of the three causes you know about?

The argument to most in the scientific community is much more strong than probably.

Point taken.

But you state bluntly that the Earth's climate is warming rapidly. I do not accept your basic premise - your basic "fact".

You then suggest that man is "probably" responsible. But the whole argument about man causing the change hinges on the assertion that it is CO2 levels that cause temperature change. As all the evidence I have seen suggests that it is the other way round - that temperature changes cause changes in CO2 levels - I find the circularity of the global-warmists case self-defeating.

I believe actual climate measurements, actual poar ice measurements that disprove the artificial models are forcing the warmists to go round in ever-decreasing circles.

Hopefully the warmists will then disappear up their own fundaments before they do lasting economic damage to the whole of mankind.

[Link: scienceblogs.com...]

Greenland used to be a lovely hospitable island when the Vikings settled it. It was not until the Little Ice Age that it got so cold they abandoned it. During that time, it was clearly not the frozen wasteland it is today.

Answer:

Firstly, Greenland is just a part of a single region and as such can not be assumed to represent any kind of global climate shift. See the article on the Medieval Warm Period for a global perspective on this time period. In short, the available proxy evidence indicates that globally warmth during this period was not particularly pronounced though certainly some regions may have experienced greater warming than others.

Secondly, a quick reality check shows that Greenland's ice cap is hundreds of thousands of years old and covers over 80% of that island. The vast majority of land not under an ice sheet is rock and permafrost in the far north. Just how different could it have been only 1000 years ago?

Here is a brief account of the Viking settlement, which was an actual historical development, based on the chapter on Vikings in Greenland in Jared Diamond's "Collapse".

Greenland was called Greenland by Erik the Red (was he red? :-) who was in exile and wanted to attract people to a new colony. He believed that you should give a land a good name so that people want to go there! It very likely was a bit warmer when he landed for the first time than it was when the last settlers starved due to a number of factors, climate change, or at least some bad weather, a major one. But it was never lush and their existence was always harsh and meagre, especially due to the Viking's disdain for other peoples and other ways of living. They attempted to live a European lifestyle in an arctic climate side by side with the Inuit who easily out survived them. For heaven's sake, these people starved surrounded by oceans and yet never ate fish! (Note: this was not a typical European behaviour and is in fact a bit of a mystery to this day).

Instead of hunting whales in kayaks, they farmed cattle, goats and sheep despite having to keep them in a barn 24 hours a day, 7 days a week, for a full 5 months out of the year! It was a constant challenge to get enough fodder for the winter. Starvation of the animals was frequent, emaciation routine. The pressures of grazing requirements and growing fodder for the winter led to over production of pastures, erosion and the need to go further and further a field to sustain the animals. Deforestation for pastures and firewood proceeded at unsustainable rates, leading, after a couple of centuries, to such desperate measures as having to cut precious sod for housing construction and even burning it for cooking and heating fuel.

When finally confronted with several severe winters in a row, they, along with the little remaining livestock, simply starved before spring arrived.

The moral of the story for the climate controversy? Much as you can not judge a book by its cover, you can't judge the climate of Greenland from its name.

A bit of related trivia: further indications of their stubborn reluctance to learn from the Inuit is that there is no evidence of any kind of trade whatsoever, this despite centuries of being neighbours. In fact, the first of only three accounts of encounters the Norse had with the natives refers to them as "skraelings" (wretches) and describes rather matter of factly how strangely and differently they bleed when stabbed with fatal and non-fatal wounds. How's that for diplomacy!?

690 dak  Sun, Aug 9, 2009 5:04:59pm

Temperature changes cause CO2 rise. CO2 trails temperature changes by a couple century.

Try living in Canada. When it's warmer, we get a longer farming season. Sometimes farmer can get two crops in, sometines 3. retarded example?

Warmer temperature means more plants means more decaying organic mass (ie dead plants, cow farts, etc) means more CO2.

Then there should be more plants, more CO2 etc etc? Unless the plants eliminate the CO2 until there is fewer plants and a new balance?

Like all sysyems this one would go back and forth, back and forth.

691 Charles Johnson  Sun, Aug 9, 2009 5:07:23pm

CO2 Lags Not Leads:

Objection:

The CO2 concentration lags behind temperature by centuries in the glacial-interglacial cycles, so clearly CO2 does not cause temperatures to rise, temperatures cause CO2 to rise.

Answer:

A close examination of the CH4, CO2 and temperature fluctuations recorded in the Antarctic ice core records does in fact reveal that yes, the temperature moved first in what is, when viewed coarsely, a very tight correlation. But what is not correct, is to say the temperature rose and then hundreds of years later the CO2 rose. These warming periods lasted for 5,000 to 10,000 years (the cooling periods lasted more like 100,000 years!) so for the majority of that time (90% and more) temperature and CO2 rose together. This means that this remarkably detailed archive of climatological evidence clearly allows for CO2 acting as a cause for rising temperatures while also revealing it can be an effect of them.

The current understanding of those cycles is that changes in orbital parameters (Milankovich and other cycles) caused greater amounts of summer sunlight to fall in the northern hemisphere. This is actually a very small forcing, but it caused ice to retreat in the north which changed the albedo. This change, reducing the amount of white, reflective ice surface, led to increasing the warmth more in a feedback effect. Some number of centuries after that process started, CO2 concentrations in the atmosphere began to rise and this also amplified the warming trend even further as an additional feedback mechanism.

You can also go here for a discussion by climate scientists of exactly this question but with greater technical detail and full references to the scientific literature.

So, it is correct that CO2 did not trigger the warmings, but it definitely did contribute to them, and according to climate theory and model experiments, greenhouse gas forcing was the dominant factor in the magnitude of the ultimate change.

Wobble.
[Link: wattsupwiththat.com...]

The melting was first caused by more solar radiation, not changes in carbon dioxide levels or ocean temperatures, as some scientists have suggested in recent years.

“Solar radiation was the trigger that started the ice melting, that’s now pretty certain,” said Peter Clark, a professor of geosciences at OSU. “There were also changes in atmospheric carbon dioxide levels and ocean circulation, but those happened later and amplified a process that had already begun.”

Historically CO2 and temperature have been in a natural equilibrium, and CO2 while implicated in climate was not a driver of climate. However, we are pumping extra CO2 into the environment over and above that which is naturally present. Given that CO2 is a greenhouse gas this increasing concentration of CO2 causes warming over and above what would naturally be the case.

From the website

The Moberg reconstruction shares the larger degree of multicentennial variability with the borehole reconstructions (see Huang 2005), but the pattern of variability is very similar to that of the high-resolution reconstructions. The authors suggest that the greater multicentennial variability could be due to natural (solar and volcanic) forcing larger than previously thought. However, model experiments indicate that the recent warming is unlikely to be due to natural forcing alone. As with the other reconstructions, regardless of the proxy data used, this reconstruction indicates that the temperatures of the last two decades are warmer than any other period in the past two millennia.

Well that's settled. The models show the last two decades of warming are unlikely to be do to natural causes alone. Better start dismantling our economy.

That's correct. It will burn up it's hydrogen and then begin fusing helium and isotopes into heavier elements, however, when this happens, there will be a different energy balance and the sun will expand and change color.

697 Jimmah

CO2 is a relatively insignificant greenhouse gas. But the "warmists" have argued from the outset that CO2 is by far the most important factor influencing temperature. That very assertion looks to me to be balderdash.

And man-emitted CO2 is relatively insignificant compared with the emissions and absorptions by the oceans. We, mankind, are a speck compared to the capacity of the oceans to absorb CO2.

The whole fault with "coby's" otherwise-worthy website is that he is preaching from just one side. he sets up each topic by stating very briefly the sceptics' view - and then spends a page or more putting all manner of arguments against it. He does NOT say - "on the one hand, on the other hand"...

713 zombie  Sun, Aug 9, 2009 5:31:26pm

re: #666 LudwigVanQuixote

Let's put this in perspective.

A rise of 3 meters is far from out of bounds possible by the end of the next century. 5-7 meters is high end.

So let's look at 3 meters rise.

That would take out, Boston, NY, Dover, Baltimore, Washington, Charleston, and Miami as well as large portions of San Francisco, San Diego to name a few.

What would that do for our economy?

3 meters = 10 feet. 7 meters = 22 feet.

End of next century? No way, Jose. No even close to happening.

Since records were first officially kept in the 19th century, sea levels have risen on the order of inches, not feet. And mysteriously, not in all places equally. I live in San Francisco and I know the waterfront area and the history of the city EXTREMELY well. There are places where you can see where the water level was in 1848, 1850, 1853, etc., up though 1906 up to the present day.

And guess what? It has not gone up one single inch in all that time. And yet that time was the period of time in human history of maximum CO2 emissions, maximum greenhouse gasses, and you'd think therefore maximum sea level rise. And yet: zilch.

So, in 160 years of greenhouse gas increases, at least here on the West coast, during that entire time the sea has encroached not at all, not one foot, not one inch, nothing. In fact, since the SF waterfront area was built up during the 19th century, the net effect was that the waterline receded by several hundred yards.

Now you're telling me that in another century, the sea level in SF is going to rise somewhere between 10 and 22 feet. And during that century, the amount of greenhouse gas pollution will be actually less than the previous century and a half, when there was basically NO pollution control on factories and cars during most of that time -- and no sea level rise.

Sorry, I'm just not buying it.

Second of all your characterization of "That would take out, Boston, NY, Dover, Baltimore, Washington, Charleston, and Miami as well as large portions of San Francisco, San Diego to name a few" is way way way overstating the case. You make it seem like these cities will simply disappear beneath the waves one day. Again, ain't gonna happen.

Sea level rise, if it happns at all, will happen EXTREMELY gradually, an inch here, an inch there. We will be able to see decades off when the rise will begin to threaten low-lying areas. And little by little, if necessary, businesses and shopping areas and homes will be condemned and demolished, and people will move inland a little bit. It's not like we'll be running from the waves as they rush inland, 22 feet high. The process will take centuries. And no one person would notice it during a ingle lifetime.

The only two cities (under your scenario) that are long-term unsustainable are Miami and part of New Orleans, which are basically at or below sea level, with no high ground to retreat to. But the rest -- not that big of a deal.

Will it impact the economy? Possibly. But it might be considered a spur to the economy in that new building projects on higher ground will employ a lot of people to replace to endangered buildings.

But even in your worst-worst-worst case scenario, cities have taken huge hits like this, and bounced back. San Francisco 1906 earthquake. Hurricane Katrina in New Orleans. 9/11 in New York. Galveston, LA, etc. -- disasters happen. And then people rebuild and life goes on.

Now, in some of these projections, they're talking about 10 feet by the year 3000. That is a little more believable, a little less wild speculation.

Hmmm, can we relocate a few office building and houses over a thousand-year time span? I think we might be up to the task.

I mostly agree with Charles on this, though I think the word "probably" may be too strong. This could be splitting hairs though. I'd say "likely" is more reasonable.

While I don't agree with the pro-AGW viewpoint, some of the things that they advocate to "fix" the problem, which takes an astounding amount of hubris in the first place to think we can "fix" a problem we may not be causing, turn out to be good ideas in and of themselves.

Lower emissions of bad things. Good.

Make power generation more environmentally friendly. Good.

re: #512 Thanos

In the past ages when Canada was swamp temperature the bugs were beer cooler sized and there were crocodiles in New York. I don't find that desirable.

Apparently you haven't been to Canada very often. Most of Canada is still a giant swamp past the 55th parrel in the spring(or what passes for spring), and bugs do nothing but eat you alive. And the further north you go, the more it's a freaking swamp until you hit solid ice or water, even then you can still run into bugs.

Confusing when you look back historically through 600 million years ago from the Cambrian Period when CO2 peaked at 7,000 ppm to modern times where CO2 is less than 400 ppm, you see absolutely no correlation between global temperature and CO2 levels.

That is, none until Al Gore left office.

I still think think there is doubt about AGW (or now called Climate Change).

However, there is absolutely no doubt that AGW is highly politicized. So much so that getting to the truth almost impossible as with anything that has become a political football.

re: #713 zombie

Short from.

1. If we were to loose both caps and Greenland, and we would also loose parts of Canada and Siberia. We would have a 10-15 meter rise.

2. Those places are going much much more quickly than originally predicted, and as the Siberian and Canadian bogs melt, they release megatons of methane, creating a very serious feedback in addition to lost albedo.

3. Look at how mild the changes have been in the last decade, and look at how much of those ice sheets we have already lost. This situation is only getting worse and it is accelerating in how bad it is getting.

4. Therefore, because of these things it is not unreasonable to expect rises that high.

I read way beyond the piece you quoted - the piece presented by the defender of "warmism". It is a long long thread. And my conclusion was that the warmism defender lost the debate.

Giggle, warmist, yeah like evolutionists and scientists... It's all a conspiracy I tell you!


697 Jimmah

CO2 is a relatively insignificant greenhouse gas. But the "warmists" have argued from the outset that CO2 is by far the most important factor influencing temperature. That very assertion looks to me to be balderdash.

Giggle, because new advances in QM show that CO2 actually does not absorb light in the IR and become hot! Who knew? It seems that energy from photons can no longer be converted into heat by molecular vibrations! There is no danger if you lock your dogs in the car anymore, provided you use evil hot fairy repellent to protect them!

And man-emitted CO2 is relatively insignificant compared with the emissions and absorptions by the oceans. We, mankind, are a speck compared to the capacity of the oceans to absorb CO2.


Actually after killing off so many photosynthesizers and saturating the oceans this is just false. I can't come up with a witty way to mock it though.


The whole fault with "coby's" otherwise-worthy website is that he is preaching from just one side. he sets up each topic by stating very briefly the sceptics' view - and then spends a page or more putting all manner of arguments against it. He does NOT say - "on the one hand, on the other hand"...

In science there is only one hand once the evidence is settled. We do not say, on the other hand, the Earth might still be flat.

That is - he sets up biased arguments that may look good. But in the subsequent threads his one-sided arguments are taken apart. or at the very least - he does not substantively prove his point.

Then you did not comprehend what you read.

re: #687 LudwigVanQuixote

The earth-sun system is a (nearly) classical 2-body problem. As is the moon-sun system. Together you get either a 3 body problem which is impossible to write down closed form analytic solutions for, or a perturbed 2 body with reduced mass system, where you can get "closed form" solutions for, if you squint really hard, and ignore the perturbations as small.

But this is also a Hamiltonian system with sinks and sources of energy. Which means you can construct phase portraits of them ... think pictures of many orbits, in terms of position and velocity. Introduce perturbations, and multiple other interactions, and you get

ta da

a chaotic system, with specific attractors. These attractors are orbital regions of, well, increased density. There are transitions between these regions.

Basically what we know, from symplectic integration of orbits over very long periods of time are that the planets don't stay in precisely the same orbits they are in now. They get shoved one way or the other, by a little, every now and then.

We don't see this typically in our lifetime time scale. But these effects do add up. And guess what. They are a force in climate conditions.

The dynamics of the orbital perturbations are similar to sympathetic vibrations of a remote system getting out of sync with the driving force.

Couple this with the precession and nutation of our own planet. You can see the nutation in your lifetime, only need to live to be 100 to see it. Precession is harder, you need to live about 13k year to see it. These all influence each other, as the nutation and precession likely impact oceanic current flows. And vice versa.

Earth wobbles are *very* important.

The thing that always gets me is when the Scary Chart (TM) is trundled out, showing how the average temperature is going up Up UP!!! OMG, we are all gonna be baked to a crisp!!! DO SOMETHING!!!

Then you look at the temperature scale...

1 degree Celsius. Over all that time, a little over one degree. Couldn't that fall within the margin of error (plus or minus two points, for example)? That chart looks a whole lot less scary when you see the scale.

Oh and by the way, just exactly what is the ideal temperature for the Earth? How do you know and can you prove it? What if you are wrong? What are YOU, personally, willing to give up FIRST before you force me to go along with your "plan"? Personally, I think that most of the more radical advocates of AGW should not own a vehicle other than a bicycle, wear completely organic clothing, not consume any electricity that they do not generate themselves (solar cells on the roof or wind turbines are fine and if they wanna build a nuclear reactor in the basement, I'm cool with that! ;-) ), not consume any food or product that is not locally produced so that it does not have to be trucked in, live in a house that does not impact the earth (heated and cooled naturally, but no burning wood or coal! Solar heating & cooking only! Unless you happen to live over a steam vent or a hot spring) and be childless so that they do not contribute any more parasitic humans to vex, beguile and ravish Gaia .

re: #689 LudwigVanQuixote

Well why don't you look at the data? Charles actually posted a link to a site that addresses that very question.

[Link: scienceblogs.com...]

Greenland used to be a lovely hospitable island when the Vikings settled it. It was not until the Little Ice Age that it got so cold they abandoned it. During that time, it was clearly not the frozen wasteland it is today.

Answer:

Firstly, Greenland is just a part of a single region and as such can not be assumed to represent any kind of global climate shift. See the article on the Medieval Warm Period for a global perspective on this time period. In short, the available proxy evidence indicates that globally warmth during this period was not particularly pronounced though certainly some regions may have experienced greater warming than others.

Secondly, a quick reality check shows that Greenland's ice cap is hundreds of thousands of years old and covers over 80% of that island. The vast majority of land not under an ice sheet is rock and permafrost in the far north. Just how different could it have been only 1000 years ago?

Here is a brief account of the Viking settlement, which was an actual historical development, based on the chapter on Vikings in Greenland in Jared Diamond's "Collapse".

Etc.Etc.

My answer:

Jared Diamond is typical of certain kind of "liberal" who is obsessed with proving that Western civilization is just another culture, no better or worse than any other.

As if the whole development of scientific thought had ever occurred in any of the other advanced civilizations which have, in other fields, like art, philosophy, and literature, created things which we can't begin to match!

The issue about Western exceptionalism used to be "How did this come to be - what made us different from all those other civilizations?" - there were arguments about Protestantism and the rise of capitalism and science, and the theories of Weber, and lots of other debates.

Now the issue is settled by simply denying that there was ever any difference! In the first pages of "Guns, Germs and Steel" Diamond speaks of a lovely native of Papua New Guinea whom he finds at least as cultured and intelligent as any European, even though he still is confused about the "cargo cult" mentality, and where things come from when the airplanes fly them in. He even makes conservative arguments about how our kids today are no better than any other country - as though this proves anything about the past, when science was growing exclusively in the West.

My point is simply that using such a person as an authority in this context is perilous.

In history class we used to learn that Eric the Red (or somebody) called Greenland and Iceland the reverse of what they actually were, in order to confuse the possible colonists. This makes a lot more sense than what Diamond talks about, since, yes indeed, the Greenland ice has been there forever. But it doesn't help the argument here, because if Iceland was green in those days, as may well have been the case, then indeed things are colder now!

As for your comment about Princeton and Harvard guys, I answered this at the end of another thread - these are political monocultures, and scientists are not immune to that. Also, scientists find what they're looking for, and make conclusions based on their ways of thinking, particularly in the era of grant-grubbing when the subject of what they're studying has to appeal to the grantors.

Just when I start to be somewhat convinced by you, Ludwig, you throw something like this into the pot, which fouls the souo, for me.

Please separate the moonbat "solutions" to the problem from the actual science.

The only way to get better solutions is if reasonable people understand the science and the very real threats of AGW. The perhaps people could demand more sensible solutions. However, by denying it exists reflexively, you have taken yourself out of any meaningful conversation about possible solutions.

735 LudwigVanQuixote  Sun, Aug 9, 2009 7:47:30pm

re: #733 harpsicon

Huh, exactly what was said in any of that that had a liberal bias?

Either Greenland's ice according to cores was mostly over 100,000 years old or not. Ice is not liberal or conservative. If Greenland was over 80% covered by politically neutral ice that is over 100,000 years old, then it is very hard to argue that Erik the Red found the place very Green only 1000 years ago.

End of story. It doesn't matter if the person telling you that were a communist. If the statement is true - and you know it is because you have seen ice core graphs that go bak for 100k year timescales, then it is done.

736 harpsicon  Sun, Aug 9, 2009 7:54:14pm

You didn't really read my post.

I think Diamond is wrong. Erik the Red switched the names of Iceland and Greenland to confuse possible colonists.

And you're right, "Greenland" was never green. But if the above is true, then Iceland may well have been green, which would imply a lot warmer climate than today.

Given Diamond's outlook, it's much more fun to interpret "Greenland" wrong and thus prove his own point. Debunking the "Medieval warm period" is crucial to AGW alarmists, and the "Hockey Stick" graph.

In a work of history, as opposed to science, it matters a great deal if somebody is a communist, a liberal, a royalist, or whatever!!

You didn't notice the bias in Guns Germs and Steel? My God, the entire book was composed of Pure Agenda. I saw bias on every page.

Diamond was trying to prove that Euro/Western civilization achieved its success by accident, not due to any special effort or smarts on the part of the inhabitants. The goal was essentially to take the Eurocentrists down a notch or ten.

He did this by trying to show that by various accidents of history, biology and geography Europe and the Middle East got lucky, history-wise, whereas the rest of the world got the shaft. And if not for this random happenstance, things could have been reversed -- i.e. Europe and the Middle East could have been the backward areas, eventually conquered and colonized by the inhabitants of other continents.

However, the book was a pristine example of starting out with a thesis you know and/or want to be true, and then searching for the data -- and only that data -- which confirms it.

I don't have the gumption to debunk the the entire book in one tiny comment -- and boy, would it take a lot of debunking, possible an entire nother books' worth -- but I will say that as I read it I saw in my mind's encyclopedic eye the counter-examples in each case that nullified his contentions.

Diamond has a lot of facts in there, but they are arranged and marshalled in the precise way to prove a pre-existing thesis. With a different selection of just-as-true facts, arranged a different way, you could prove basically the opposite.

What is not in dispute is that the earth is currently warming, and that human activity contributes to that to some degree.

What IS being questioned is the sensationalist alarmist doomsday scenario that all the ice caps - Arctic, Antarctic, and Greenland - are gonna somehow completely melt away in the next hundred years, causing a rise in sea levels of more than 30 feet. Especially, when not only the mutually corroborating IPCC and Bristol studies find no basis for such a Day After Tomorrow Hollywood catastrophist tipping point scenario, but so do other studies as well:

1. Polar ice has been observed to melt much faster than predicted in your paper or the IPCC report because it is a not well understood non-linear system and therefore hard to model correctly.

2. The observed melt curves have positive second derivatives, therefore the rate of melt keeps increasing i.e. they keep melting faster and faster.

Look at the bit from NASA.

"If the Greenland melt continues to accelerate, we could see significant impacts this century on the northeast U.S. coast from the resulting sea level rise," says NCAR scientist Aixue Hu, the lead author. "Major northeastern cities are directly in the path of the greatest rise."

Scientists have been cautious about estimating average sea level rise this century in part because of complex processes within ice sheets. The 2007 assessment of the Intergovernmental Panel on Climate Change projected that sea levels worldwide could rise by an average of 7 to 23 inches (18 to 59 cm) this century, but many researchers believe the rise will be greater because of dynamic factors in ice sheets that appear to have accelerated the melting rate in recent years

I am one of those many scientists who believes that it will be worse than that. My statement was, and always has been, "It is not unreasonable to fear that we loose both caps in the next 100-150 years" I did not say we will definitely loose absolutely everything by 2100, I said that even that is possible and that IPCC is a candy bar estimate.

I said that it is not impossible to rule out a three meter rise either by the end of the century.

If things continue as they are now, even by IPCC, we loose both caps and most of Greenland by 2200. Just shut up and process what it means.

746 Salamantis  Sun, Aug 9, 2009 8:34:46pm

There is no ice melt rate at 0 F, and obviously a quite rapid one at 212 F. It would seem to me that it is basic science that should be well known as to what the ice melt rate is for each degree in between.

Please furnish me the graph that demonstrates that a gradual increase of 7 degrees results in an ice melt rate 492.125 times faster, which is what would be required for the 8 inch rise in sea levels over the past century to explode into a ten meter rise in the coming century.

It's not straightforward solely with temperature - and you can verify this this winter after the first good snowfall. Melt rates are affected by day vs. night, direct sunlight vs. overcast, precipitation, wind, and other factors as well. All of these are factors in local and regional climate.

If you want to research the polar ice caps, check these three sources (from the US, Norway & Japan, respectively):

[Link: nsidc.org...]

[Link: arctic-roos.org...]

[Link: www.ijis.iarc.uaf.edu...]

Each one has details the others don't. Browse around in the US site and you'll learn a lot (for example, the Antarctic sea ice is increasing and this year will is tracking above 2008, which is displayed because it was all time record HIGH year -- in the satellite era only, of course). Follow the concentration map for a few weeks and you can begin to forecast the extent (as you can see where the concentration is approaching the 15% threshold).

The JAXA site has a downloadable CSV file which shows that the arctic has been losing about 47,000 sq. km. per day for the last 10 days or so.

All together, it's pretty easy to project that the 2009 Arctic sea ice extent will soon be significantly above the 2008 extent (as shown on the JAXA graph). If the Northwest Passage doesn't open up in September (like it did the last two years) it'll be news. Some people were counting on it.

Yes, parts - small parts, actually, of Brooklyn, Queens and Staten Island would also be affected but NYC is relatively HIGH in terms of it's basic land mass.

It's hard to answer your question unless you're more specific. On the one hand the preponderance of evidence should point you to what is most "likely". On the other hand how much evidence (and of what?) is ever "enough"?

Hey LVQ, it might be helpful to list some of those refs anyway. First to show they exist, and second for folks who do have access to them.

Good point.

I'll give some more journal references :

Sunlight, water, and ice: Extreme Arctic sea ice melt during the summer of 2007
D. K. Perovich, J. A. Richter-Menge, K. F. Jones, B. Light,

Here is the abstract:

The summer extent of the Arctic sea ice cover, widely recognized as an indicator of climate change, has been declining for the past few decades reaching a record minimum in September 2007. The causes of the dramatic loss have implications for the future trajectory of the Arctic sea ice cover. Ice mass balance observations demonstrate that there was an extraordinarily large amount of melting on the bottom of the ice in the Beaufort Sea in the summer of 2007. Calculations indicate that solar heating of the upper ocean was the primary source of heat for this observed enhanced Beaufort Sea bottom melting. An increase in the open water fraction resulted in a 500% positive anomaly in solar heat input to the upper ocean, triggering an ice–albedo feedback and contributing to the accelerating ice retreat.

Here is a paper that sums up state of many models.

I misplaced a decimal point. The melt rate would have to be 49.2125 times faster.

And this would be a 4921.25 % increase.

No because, because it is still melting as we speak, we are still dumping more and more carbon into the atmosphere, we are still killing plants and algae and we are still saturating the oceans.

This year we are not having the same el nino we had before so we are getting a little local (in terms of time) break. The overall patterns are what is important.

769 Tatterdemalian  Sun, Aug 9, 2009 9:11:22pm

I would be more convinced if all the entries I've read on the page didn't pretty much run similar to this one:

"Warming on another planet would be an interesting coincidence, but even if it were the case it does not necessarily have to have the same cause. The only relevant factor the Earth and Mars share is the sun, so if the warming were real and related it would logically be due to the sun. Well the sun is being watched and measured very carefully back here on earth and it is not the primary cause of the current climate change.

As for this alleged extraterrestrial warming, there is very little evidence to go on when it comes to discerning a global climate change on Mars. The only evidence out there that I am aware of is a series of photographs of a single icy region in the southern hemisphere that shows melting over a 6 year period (about 3 Martian years). Here on earth we have direct measurements from all over the globe, widespread glacial retreat, reduction of sea ice and satellite measurements of the lower troposphere up to the stratosphere. To compare this mountain of data to a few photographs of a single region strains credulity. And in fact, the scientists studying Mars believe the observation described above is the result of a regional change caused by Mars' own orbital cycles, like what happened during the earth's glacial cycles...

...I think anyone trying to draw conclusions about what is happening here on earth from all this might as well be from another planet.

Back to Mars for a quick summary:

On Earth, we have poles melting, surface temperature rising, tropospheric temperatures rising, permafrost melting, glaciers world wide melting, CO2 concentrations increasing, borehole analysis showing warming, sea ice receding, proxy reconstructions showing warming, sea level rising, sea surface temperatures rising, energy imbalance, ice sheets melting and stratosphere cooling which leads us to believe we have global warming driven by an enhanced greenhouse effect.

One Mars we have one spot melting which leads us to believe...one spot is melting.

Forgive me for not being reassured!"

Okay, so rather than any kind of analysis of the data, we have an abrupt dismissal of a small amount of data that has even the tiniest chance of contradicting his "mountains of evidence," a lovely little listing of all the doom-and-destruction environmentalists have been promising for the last fifty years (none of which has ever turned out to spell the end of humanity, even where it did come to pass), and a flat rejection of any possible reassurance.

Forgive me for not being convinced by the "How to Treat Climate Change Deniers Like The Ignorant Choads They Are" web site. The geocentrists had mountains of evidence the Earth was fixed in the center of the universe, too, and all it took was a telescope that could distinguish the phases of Venus to destroy it all.

And why the financials that might make it worth our time don't exist either.

Also, I didn't put in that the NYT book section will hardly push such a book either, certainly not the way they pushed G,G and T, making it sound like such a wonder.

For a parallel situation, look at all the Post-Colonialist reinterpretation of the history of the Middle East. A few people have written the correctives, but they are overwhelmed by the alarming number of new PC efforts by all those Univ. newbies looking for careers in the hideously slanted (if not Saudi-funded) Middle East Studies departments (or whatever they call them).

You are right in everything you have said, and my field is actually Chaos Theory - and the systems I study are turbulent atmospheric flows.

My claim is that we have ruled out wobbles as the cause of the current warming trend. This is a correct statement.

Who is "we"? My husband is a wobble expert. Did you factor in the 2004 earthquake/tsunami? That changed the wobbles. so did 1960 earthquake in Chile . 1700 Earthquake off Northern Cali too. There not enough precision developed to rule out wobbles here. Your statement is incorrect. BTW "they" use paleo-climate data to figure out the paleo-wobble data sometimes.

For instance: Pointing to ice melting in Greenland is easy to do but what it means or "shows" is being spun here by people like Coby Beck, who is non earth scientist with political glasses. In the last million years there's been 22 or so ice advances and retreats in the Northern Hemisphere. They will point to 100,000 yrs old ice melting (no link to what extent either) in Greenland but those same people won't tell you that the ice in Greenland is NEW in earth age even though it's 100,000 yrs old.

The we is the vast bulk of scientists I know. The sorts of shifts in the Earth's orbit orientation of that could cause warming/cooling periods of any large scale are pretty well known, and we are not experiencing such a period now.

784 Salamantis  Sun, Aug 9, 2009 9:45:32pm

[Link: earthobservatory.nasa.gov...]

To assess the impact of Greenland ice melt on ocean circulation, Hu and his coauthors used the Community Climate System Model, an NCAR-based computer model that simulates global climate. They considered three scenarios: the melt rate continuing to increase by 7 percent per year, as has been the case in recent years, or the melt rate slowing down to an increase of either 1 or 3 percent per year.

If Greenland's melt rate slows down to a 3 percent annual increase, the study team's computer simulations indicate that the runoff from its ice sheet could alter ocean circulation in a way that would direct about a foot of water toward the northeast coast of North America by 2100. This would be on top of the average global sea level rise expected as a result of global warming. Although the study team did not try to estimate that mean global sea level rise, their simulations indicated that melt from Greenland alone under the 3 percent scenario could raise worldwide sea levels by an average of 21 inches (54 cm).

If the annual increase in the melt rate dropped to 1 percent, the runoff would not raise northeastern sea levels by more than the 8 inches (20 cm) found in the earlier study in Nature Geoscience. But if the melt rate continued at its present 7 percent increase per year through 2050 and then leveled off, the study suggests that the northeast coast could see as much as 20 inches (50 cm) of sea level rise above a global average that could be several feet. However, Hu cautioned that other modeling studies have indicated that the 7 percent scenario is unlikely.

In addition to sea level rise, Hu and his co-authors found that if the Greenland melt rate were to defy expectations and continue its 7 percent increase, this would drain enough fresh water into the North Atlantic to weaken the oceanic circulation that pumps warm water to the Arctic. Ironically, this weakening of the meridional overturning circulation would help the Arctic avoid some of the impacts of global warming and lead to at least the temporary recovery of Arctic sea ice by the end of the century.

Sal: Thank you for unintentionally supporting my position. Six feet is "several feet", and that's only under the worst case scenario, which the article adds is "unlikely."

And even the unlikely six feet - that is, around two meters - is a helluva lot closer to the Bristol/IPCC one meter scenario than it is to your ten meter scenario.

I'm going with the contemporary science. It makes no more sense to assume that the increase in sea levels will be much MORE severe than that science shows as to assume that it will be much LESS severe. Let's try to deal with the degree of problem that the science tells us we have. When the science changes, then is when to change our countermeasures, and not before.

When a thunderstorm is predicted, I do not put up my hurricane shutters. But I do bring in things I don't wanna see get wet or get blown around.

Which is why we should transition to nuclear power. We should conserve our declining petroleum resources (we have already reached peak oil) for purposes for which we have no inexpensive plentiful substitutes (plastics, chemicals), and it does no good to have electric cars if their batteries are being recharged from coal or oil fueled power plants. Not to mention that burning coal or oil for energy is toxic and polluting, even aside from the CO2 they add to the atmosphere.

If carbon emissions are truly so terrifying, why are all the programs so determined to stop people from emitting carbon (by starvation if need be), rather than engineering ways to remove the emissions from the air?

Are we really that determined to begin sacrificing our fellow humans for fear of impending disaster, in the hope that it might be slowed? Or is the elimination of certain inconvenient people the real point, and global warming a convenient means to that end?

I would rather let the disaster happen, let global warming choose how many must die and who they should be, than allow any mortal man or committee of them be that decider. Better blind justice than clear-eyed genocide.

797 Salamantis  Sun, Aug 9, 2009 10:22:21pm

For the ten meter scenario to happen, a projected global temperature increase of just under 7 degrees would have to result in an ice pack melt rate increase exceeding 4900 %.

re: #796 Tatterdemalian

If carbon emissions are truly so terrifying, why are all the programs so determined to stop people from emitting carbon (by starvation if need be), rather than engineering ways to remove the emissions from the air?

Are we really that determined to begin sacrificing our fellow humans for fear of impending disaster, in the hope that it might be slowed? Or is the elimination of certain inconvenient people the real point, and global warming a convenient means to that end?

I would rather let the disaster happen, let global warming choose how many must die and who they should be, than allow any mortal man or committee of them be that decider. Better blind justice than clear-eyed genocide.

NO, as resources became scarce there would be plenty of clear eyed genocide fighting over them and through starvation... I really fail to see how switching over from fossil fuels to cleaner energy sources counts as clear eyed genocide. Could you please explain the concept to me?

re: #5 Charles

There are two problems with this:

1) anotherindyfilmguy said, 'Sorry, but "global warming" is the Sun going through natural cycles.' This article addresses only solar irradiance, which is only one aspect of solar radiation. As such, it is something of a strawman.

2) The article itself is self-contradictory. It says you really need satellite info to measure solar irradiance (which seems reasonable, although irrelevant to the debate). Then it goes on to say that somebody is trying to "reconstruct the record" before there were satellites. Besides sounding a bit Stalin-esque, it doesn't lend to their credibility.

I'm not sure anybody has a THE theory on HOW solar cycles might effect global climate, but solar activity has tracked well with climate change in the past. One possibility being looked into is that the solar wind sheilds the Earth from cosmic radiation, which effects the atmosphere. But they "conveniently" left that out of their article, didn't they?

The three meter scenario is all the way at one end of the prediction spectrum, and is no more likely than the few centimeter scenario at the other end. And the ten meter scenario is totally beyond the pale, despite your efforts to rule it in.

re: #50 Killgore Trout

See this section: This is Just a Natural Cycle

Wow, that section was lame!

For example, we have:

...Secondly, a "natural cause" proponent needs to come up with some explanation for how a 35% increase in the second most important greenhouse gas does not itself affect the global temperature. Theory predicts that the temperature will rise given an enhanced greenhouse effect, how is it possible this is not happening?

Um, no - the folks with the extraordinary claims (which AGW certainly is) have the burden of proof. They don't get to claim "we're right, and if you don't believe us you have to come up with your own theory".

Secondly, it's nice that they recognize CO2 as being 2nd (for once), but it's a distant second. It remains to be shown how much effect even this 2nd GHG has. It could be so small that secondary effects it causes are more important (which is to say, there could well be feedback mechanisms that tend to stablize global temperature). They also fail to point out that mankind only contributes a small fraction of this second GHG.

Third, if the theory predicts rising temperature with rising CO2, how come it hasn't happened in 10 years?

Fourth, the article reflects a general attitude of "how can it NOT be true"? Which should tell you something right there.

Then there's my personal favorite:

... there is no theory of climate in which CO2 does not drive the temperature.

Which is hilarious, when you consider that this gem is being offered up as PROOF of something! It sounds like something a child would come up with.

But there's also:

...the natural cycle precedents do not show the same extreme reaction we are now witnessing.

Er - actually, there are photos of submarines surfaced at a melted North Pole 40 years ago, history tells us they were growing vineyards in Greenland 1000 years ago, and there were those pesky Ice Ages. So sorry, it's been all over the map before!

Definitely. We had some performance art on this thread asserting that doing anything to slow or stop global warming would somehow be engaging in 'cleareyed genocide', and that the commenter prefers the 'blind justice' of letting all the coastal areas flood. Natural selection, baby! Let those areas flood, and those too stupid, or weak, or poor to get out of the way-- well, that's their own fault, isn't it?

Just like earlier someone proposed that letting the arctic circle turn into a rainforest would be good, because rainforests have the most biodiversity.

OK quiz time Sal,

This one only takes algebra, middle school physics and a little web research.

Air has a certain specific heat. How much energy is stored in the atmosphere of the Earth if the whole thing rises on average by just seven little degrees...

BTW Sal are those degrees Celsius or Fahrenheit?

Now, why is it more useful to look at energy instead of temperature when talking about phase transitions? That's the physics question... Hint, because ice stays at 0 degrees celsius as it melts, you have to overcome heat of fusion.

So what does that mean Sal? Seriously, this will directly address your objections and allow you to calculate why you need to think about this differently than you are.

re: #764 Coracle

I'm sorry, but that sounds to me like a cop-out. If it's the truth, it's worth the effort. It is easy to say "Sure I can prove you wrong, but I'm not going to waste my time", but it won't convince anyone who's not already convinced before you start.

I'm serious. I _want_ to see a well researched, point by point rebuttal of GG&S. Give me the facts and let me make up m mind, because the facts I see so far don't _look_ cherry picked to me. I'm new, so I don't know if you or zombie could indeed successfully rebut the book. But if GG&S is to be held up as an example of biased ends-dictate-means, agenda-addled research, then someone who held that opinion should have taken it down over the last decade.

You obviously know very little about the book publishing industry. No rebuttal of Guns, Germs and Steel -- no matter how well-written -- would have a chance in hell of ever getting published (at least by a major publisher). The leftist lockstep groupthink is stronger in the book publishing industry than in any other industry, including newspapers and academia. ALL the major publishers without exception reject without comment any manuscript from anyone that challenges major leftist memes. They will even do this to their own significant financial detriment.

That's why even people like Michelle Malkin, who has all the makings of a star and who writes books that become #1 bestsellers (as her current book is) must resort to having her book published by the sole "specialty" publisher Regnery which is the one and only book publisher with any marketing skill which specializes in conservative authors. But Regnery is not considered a "major" publisher, just seen by almost everyone in the industry as sort of an icky bottom-feeding company which gives voice to fascists just so they make make a buck. But instead the folks at Regnery are very clever, stepping into a breach in the market and snapping up all the lost opportunities all the other publishers refuse to take advantage of. As a result, this little upstart company has had several extremely profitable bestsellers -- all by conservative authors.

All of this is a roundabout way of saying that if i or anyone were to take the extreme amount of time requred to rebut GG&S, we'd either have to go with Regnery of some tiny press with no distribution. And if Regnery says no to that manuscript -- which they may very likely do, because these days only books by pre-existing media celebrities have much of a chance to sell a lot of copies -- then the author is out of luck and has basically squandered years on a futile pursuit.

And yes, we're talking about years of effort. Jared Diamond I think once said he spends many years researching and writing each book. It would just as long to rebut.

And what good would it do me even if I did write the book and get it published? Just to satisfy the demands of one curious LGF commenter? GG&S is now a standard textbook in college classrooms across the country, and my book would certainly be ignored. So the audience I would be intending to reach with my rebuttal -- mostly college students -- would never see it.

I know it's frustrating from your end to hear someone say that they could prove a point, but don't have the time to do so. And you are free to dismiss my claim. But it is the truth -- I really do have extremely limited free time, and must choose my battles very very carefully. Do I want to spend the entire Obama administration futilely typing away to cast doubt on a decade-old book? No, I don't.

I see things every single day of my life that i know are lies or distortions, and in 99% of the cases I don't have the time or energy to "do anything about it." GG&S is just one random book out of countless books I'd love to debunk given an infinitude of time and resources.

Except that, unfortunately, that shift - unlike the scientific consensus shift being proferred here - CAN indeed happen in the absence of corroborating empirical evidence, since it is not a matter of empirical science, but of public opinion.

I thought I had been clear, that it doesn't have to be about irradiance in order to be about the Sun, so the answer is "no". The Sun can effect the atmosphere, both directly and indirectly, such that more or less heat is allowed to escape.

Regnery Publishing exists solely to pump out the wingnut welfare to people like Malkin.

BTW, ever notice the little symbol next to books published by Regnery (and some other conservative "bestsellers") on the NYT bestseller list?
That's there to indicate that the reason it's on the list at all is because many of the purchases were in bulk buys. In other words, wingnut foundations will place an order for 30,000 copies or so through one of the outlets the NYT tracks-- with the sole purpose of ensuring the book winds up on the bestseller list.

That's astroturfing on the bookbuying level. That's also why reputable publishers won't touch that crap.

Research is often "wordy".
'Open condescension' is a matter of tone-- not truth.

Something can be 'wordy' and even 'condescending', yet be none the less true.
These aren't objections, they're excuses.

That's a fine exercize in cherry-picking, so thank you for that (sarc).

The obvious point is that the authors are obviously neither unbiased nor the least bit interested in getting at the true science of the matter.

re: #836 Optimizer

I thought I had been clear, that it doesn't have to be about irradiance in order to be about the Sun, so the answer is "no". The Sun can effect the atmosphere, both directly and indirectly, such that more or less heat is allowed to escape.

Irradiance is how much energy is coming from the sun via light. The electromagnetic field is really the only way that the sun communicates to us that can strongly affect temperature. It's hot in the sunshine and cool in the shade right? Energy really is conserved. By what mechanism other, than how much the sun is light shining on us can the sun be warming us?

re: #829 LudwigVanQuixote

OK quiz time Sal,

This one only takes algebra, middle school physics and a little web research.

Air has a certain specific heat. How much energy is stored in the atmosphere of the Earth if the whole thing rises on average by just seven little degrees...

BTW Sal are those degrees Celsius or Fahrenheit?

Now, why is it more useful to look at energy instead of temperature when talking about phase transitions? That's the physics question... Hint, because ice stays at 0 degrees celsius as it melts, you have to overcome heat of fusion.

So what does that mean Sal? Seriously, this will directly address your objections and allow you to calculate why you need to think about this differently than you are.

First, the current average prediction is 5-6 degrees C, which translates into 9-10.8 F. although some people predict lower increases, and other people predict higher ones. The IPCC Chairman and 2008 Nobel Laureate, Dr. R. K. Pachauri, for instance, predicts a 2.5 C - 4.7 C rise, with an outside chance of a total rise of 7 C.

Let's get YOU to surf the web, and come up with linkable evidence that such an increase will result in a 4921.25% increase in melt rate.

Or does the hamster game go only one way for you?

re: #773 Coracle

OK, you don't have the time. Zombie doesn't. _No one_ to whom it matters has, over the last 12 years, taken the time to take down GG&S? Is it really because there's enough of a financial or prestige compensation for the sacrifice of time an research? Or is it perhaps because it's not really as easy to prove your contention as you say. How can _I_ know if I don't see the arguments? Am I supposed to trust your say so by word only?

Yes, the barrier is that there is almost no financial or prestige compensation for rebutting GG&S or similar books. Years of effort with very little -- and possibly zero -- payoff.

And the end result is exactly as you say -- the books remains unchallenged, because readers like you think that if it hasn't been rebutted, therefore it isn't rebuttable.

Nothing I can do about that. You are free to believe the thesis in GG&S, as you want to do. That's fine. I'm just saying for me, from my point of view (which you can ignore if you want), the book is a transparently obvious example of "advocacy journalism" (courses in which Diamond has taught and/or guest-lectured, btw).

(And in case you are unfamiliar with the term: "Advocacy journalism" means to use the accumulated credibility of the profession of journalism to promote an agenda-- almost invariably a leftist/Marxist agenda -- under the guise of impartial reportage. Learning how to do so is a common theme is most journalism schools since the '90s.)

GG&S is hundreds of pages long with thousands of facts marshalled in a very intricate and detailed thesis. It would literally impossible for me to even begin to address the flaw in even one of his many supporting arguments in such a short venue as a blog comments section, and my motivation to do so in a longer venue is, as mentioned above, minimal because I get nothing out of it.

So, all I'm asking of you is to take away the fact that: There are people who cast aspersions on and scoff at the theses in GG&S. I'm not asking you to accept that point of view without the evidence you require -- only telling you that such GG&S-doubters exist. If that information is of no interest to you, you can freely ignore it.

Sal, Ice does not change it's temperature when it melts. The ice is at 0 degrees and the water that just melted is at 0 degrees. This really is the answer. If you have enough energy in that rise to melt the ice, you will. Now this is even more complicated by the weird ways ice breaks up and then melts faster, but you are stuck on the 7th grade part of the problem.

The argument that you are trying to make is not about temperature at all, it is about energy.

Seriously Sal, you are correct, ten meters is unlikely by the end of the century, the claim is that it can not be ruled out.

So let's say one meter is correct... that all of the weird ways ice has been observed to be breaking up average out in the long term to our benefit. That too will take out many of America's most important cities. And you still haven't addressed the changing growing patterns.

Can you at least acknowledge that the scenario you are so fervently arguing for is really bad enough as it is? I truly hope it is only that bad. I've said that bunch's of times.

First of all the whole cosmic ray cooling thing was debunked,, but that is not addressing the question. You see we are getting hotter, not colder. So where is the energy to make us get hotter coming from if not the sun? Further, if the sun is not outputting more energy, then solar variations can not be heating us up. There must be something on Earth trapping the energy it gives us better.

No please, I know this is very difficult elementary school level science, but please try to answer the question.

For solar cycles to be driving the warming there would have to be a substantial increase in irradiance yes? More energy -> more heat... Does that follow?

It would mean that solar output would have had to been rising steadily for the last century to produce the observed changes over the last century right?

So if it turns out that the sun's average output has NOT changed over the last century, the hypothesis is disproved right?

Guess what? The sun's average output has not changed.

So what does that do to your hypothesis?

NO Sal, I will explain it.

If you want to calculate how much ice will melt, you can't do it directly in terms of temperature because the ice stays at the same temperature through the entire process of melting.

Got that?

You must overcome the heat of fusion, which is to say, put enough ENERGY into the ice to break up the crystal lattice. That energy comes from the atmosphere. Energy is conserved and systems equilibrate to a central temperature.

The ice cools the atmosphere as it melts. Energy is conserved. And the temperature of the atmosphere is directly related to the temperature through it's specific heat.

However, as the atmosphere looses that energy, the ice melts. How much melts is related to the heat of fusion for the ice. So you see, the question is about energy and not temperature because the ice is not changing it's temp when it melts!

Now it turns out, that there is a lot of atmosphere, so the amount of energy in an atmosphere heated by more than seven degrees is enormous! Also don't forget that the sun keeps beating down and adding even more energy all through the process, and that as the ice melts, less of the sun's light gets reflected. Instead it heats up the water (as in dumps thermal energy into it). The same heat of fusion argument applies to water melting ice also!

This is the most basic thermodynamics. It is covered in high school. It is covered in freshman chemistry. It is covered in freshman physics.

You don't even get this!

"Social Impact of Mass Media
Instructor: Andie Tucher
Wed. 4 to 6 p.m.
In this course we explore the social consequences of what journalists do and the complex relationships between the press and the public. Through readings, class discussions, and close observations of media past and present, we locate the work of journalism in its social, historical, and theoretical context, focusing on such topics as the media's obligation to society; relationships between the press and the theory and practice of democracy; the media and storytelling; social ramifications of new technologies and new economic structures; and how the media are implicated in our perceptions of time, space, memory, and identity."

That right there is a course in "advocacy journalism."

Here's another, oozing code words:

"Critical Issues in Journalism 2 credits
Instructors: David Klatell, Andie Tucher Fri., 12:30-3 p.m., Richard Wald Thurs., 7-9 p.m.
This course, required of all students, explores the social role of journalism and the journalist from legal, historical, ethical, and economic perspectives. ...etc."

Feynmann indeed did not suffer fools gladly, which leads me to believe that he would not suffer you at all once you came out with the insane notion that a 7 degree C increase in air temperature could cause a 4921.25% increase in ice melt rate.

Oh my god, you're going to resort to claiming that these are 'code words' about a Leftist/Marxist (whatever THAT is) agenda!

here's some news: journalism does have a social impact. Understanding and acknowledging that is NOT the same as your hysterical claim that journalists are being indoctrinated in presenting a particular agenda, let alone a 'leftist/marxist" one.

These courses you find so sinister are exactly like the courses one would find in any graduate program-- courses which examine the profession/methodology from a meta-level.

Really, if you want to claim there are problems with the MSM, yes. If you want to claim there is bias in media, yes. If you want to discuss problems in academia, we can do that.

Claiming that J-schools are indoctrinating graduates in a leftist/marxist agenda and how to promote it is insanity. Kook fooder for conspiracy theorists. Something I'd expect from a lunatic like David Horowitz, frankly.

Heat of fusion and how ice actually melts is the actual reason why seven degrees is such a big deal you complete idiot. It is an explanation that a non brain damaged 7th grader should be able to follow. You are only one small step removed from the other idiots posting conspiracy theories here.

Sunlight, water, and ice: Extreme Arctic sea ice melt during the summer of 2007
D. K. Perovich, J. A. Richter-Menge, K. F. Jones, B. Light,

Here is the abstract:

The summer extent of the Arctic sea ice cover, widely recognized as an indicator of climate change, has been declining for the past few decades reaching a record minimum in September 2007. The causes of the dramatic loss have implications for the future trajectory of the Arctic sea ice cover. Ice mass balance observations demonstrate that there was an extraordinarily large amount of melting on the bottom of the ice in the Beaufort Sea in the summer of 2007. Calculations indicate that solar heating of the upper ocean was the primary source of heat for this observed enhanced Beaufort Sea bottom melting. An increase in the open water fraction resulted in a 500% positive anomaly in solar heat input to the upper ocean, triggering an ice–albedo feedback and contributing to the accelerating ice retreat.

re: #865 zombie

Here's the 2008 mandatory course catalog for Columbia J-School, and sprinkled through it are obvious code phrases for teaching students how to slip an agenda into their reportage:

"Social Impact of Mass Media
Instructor: Andie Tucher
Wed. 4 to 6 p.m.
In this course we explore the social consequences of what journalists do and the complex relationships between the press and the public. Through readings, class discussions, and close observations of media past and present, we locate the work of journalism in its social, historical, and theoretical context, focusing on such topics as the media's obligation to society; relationships between the press and the theory and practice of democracy; the media and storytelling; social ramifications of new technologies and new economic structures; and how the media are implicated in our perceptions of time, space, memory, and identity."

That right there is a course in "advocacy journalism."

Sorry, zombie, I don't mean to bash you too much on this-- but seriously, you just bolded "the press and the theory and practice of democracy" as an example of a sinister 'code word'. That is lunacy. A free press is a guarantee of a democracy-- some would say one of the most fundamental of guarantees. Like those wacky leftist/marxists we call the founders.

Why bother Sal, in order to explain to you why the solar heat anomaly is important, you would need to understand the difference between heat and temperature.

In order to understand the feedback loop from the currents and the reduced albedo, you would need to understand what a non-linear system is.

In order to understand how these things mean that the ice is melting faster and faster and how to extrapolate from that, you would need to at least know what melting faster and faster means in this case.

And in order to understand that 10 meters is a possibility that can not be ruled out, but not in my opinion probable, I think it will be like 3, you would need to understand the difference between possible and probable.

Kook kook kooky -- that's me!

I know vastly more about this particular topic than I can let on in a public forum. Call me kooky if you want, I don't care. But I know what goes on in these classes, and I've seen it with my own eyes more times than I can count.

The argument presented generally goes like this, starting with the postmodernist/deconstructionist theory about the lack of there being a neutral objective observer; a putative schematized lecture would go...:

"It is impossible to be 'neutral' in your reporting. Even when you think you are being neutral, you are unconsciously taking a viewpoint, because by being robotic and unemotive is itself a statement and a point of view. Every fact you don't include biases your coverage; and since you can't possibly include all facts in every article, whatever you write will necessarily have a slant, whether you intend to or not and whether you are aware of it or not. Even the choice of what to cover and not cover is inherently 'taking sides.'

Now, since you cannot escape from having bias in your reportage, instead of falling into the age-old trap of promulgating a viewpoint unconsciously or unwittingly, it is more astute to become aware of all possible built-in biases, and then choose the one that is either best from your point of view or which you feel is best for society. Seize control of your unavoidable bias -- don't be a passive victim of it."

Then, when advising students on what topics to cover for their sample stories/class assignments, the teachers steer them each into stories that have a "social justice" angle. The students then get the message. (And, to be frank, most college students and especially most J-school students are generally liberal/leftist anyway, so the teacher doesn't really need to do much nudging.)

Specific examples that I have personally observed: Student who initially chose to do a story about programs for drug-addiction was steered by the professor to instead do a story about a particular teenage heroin addict and to trace back where the heroin came from and how that ties into (a leftist interpretation of) global geopolitics. (e.g. the kid is addicted to heroin because we overthrew the Taliban who had suppressed opium production in Afghanistan, hence the war is bad, etc.). Another example: Student encouraged to track down former residents of a Nevada town that was downwind from an above-ground nuclear test in the '50s; and to tell their tales of woe and illness ever since, in a rather obvious attempt to make the U.S. nuclear program look nefarious; etc. etc.

I could go on all night but I don't want to reveal too much. This is how it goes.

Obviously the teacher doesn't stand up in front of the class and announce "Hail Marx! Today the indoctrination begins!" Instead, it is subtle, clever, and quite well-done.

Ah, the butterfly theory catastrophist tipping point dodge.

There isn't a concatenation of force-multiplying intervening factors separating air temperature and ice melt rate. They are linked in a direct causal relationship. Change in one entails change in the other. But a 7 degree C increase in air temperature cannot cause a 4921.25% increase in ice melt rate.

893 Salamantis  Mon, Aug 10, 2009 1:48:29am

The butterfly effect depends upon SDIC (Sensitive Dependence upon Initial Conditions), and goes thusly:

[Link: en.wikipedia.org...]

Small variations of the initial condition of a dynamical system may produce large variations in the long term behavior of the system. This is sometimes presented as esoteric behavior, but can be exhibited by very simple systems: for example, a ball placed at the crest of a hill might roll into any of several valleys depending on slight differences in initial position.

The phrase refers to the idea that a butterfly's wings might create tiny changes in the atmosphere that may ultimately alter the path of a tornado or delay, accelerate or even prevent the occurrence of a tornado in a certain location. The flapping wing represents a small change in the initial condition of the system, which causes a chain of events leading to large-scale alterations of events. Had the butterfly not flapped its wings, the trajectory of the system might have been vastly different. While the butterfly does not "cause" the tornado in the sense of providing the energy for the tornado, it does "cause" it in the sense that the flap of its wings is an essential part of the initial conditions resulting in a tornado, and without that flap that particular tornado would not have existed.

Sal: as I stated before, we are not dealing with a concatenation of force-multiplying intervening factors, but a direct causal relationship.

The butterfly effect is real. It just doesn't apply to the relationship between temperature rise and ice melt rate, and cannot be employed to justify claiming that a 7 degree C increase in air temperature can cause melt rate to increase by 4921.25%.

Just because you like chaos theory doesn't mean that every causal relationship is chaotic. In fact, most of them are not; Boyle's Law, for instance.

[Link: en.wikipedia.org...]

Your ability to wiki is very impressive. So if the butterfly effect is real, then is it the tipping point that you think is a dodge that you don't believe in?
Also, that sort of sensitivity to initial conditions is a hall mark of non-linear systems. Could you please tell me how the non-linear systems involved in ice break up would not be sensitive to initial conditions?

Sal: as I stated before, we are not dealing with a concatenation of force-multiplying intervening factors, but a direct causal relationship.

What force? There are four known fundamental forces. Stong and weak nuclear force, electromagnetism and gravity. There is some string theory speculation about the possibility of a fifth force, but that is another matter. What force is at work here to be multiplied? There are apparant forces like the force from a spring (which ultimately comes from E&M). There are pseudo forces like centripetal force.

What force is being multiplied? What does multiplying a force mean?

The butterfly effect is real. It just doesn't apply to the relationship between temperature rise and ice melt rate, and cannot be employed to justify claiming that a 7 degree C increase in air temperature can cause melt rate to increase by 4921.25%.

But Sal, I didn't say that the butterfly effect was breaking the ice or melting it. I asked you why you think Seven degrees is too little. Come on Sal, you said it dozens of times with great certainty. You must have some reason to say it so strongly. What is it?

Just because you like chaos theory doesn't mean that every causal relationship is chaotic. In fact, most of them are not; Boyle's Law, for instance.

Both of these statements are true Sal, but how do they answer how you think this works, or why seven degrees is too small. It is really a simple question Sal, why do you think it can't do it? By what mechanism?

Don't gloat yet Sal, just answer the question. It's really simple. You claim seven degrees can't do it. Why can't seven degrees not do it?

Because an increase of 7 degrees C would have to be able to increase the ice melt rate by 4921.25% in order to melt through thousands of square miles of a miles-thick Greenland ice cap in a century. And you cannot demonstrate that an increase of 7 degrees CAN do such a thing. Nor can any cybersource you can find, because I'm quite certain that you have been frantically Googling for any straw you can grasp, and come up empty-handed.

Extraordinary claims require extraordinary evidence. And since you were the one who initially claimed that the ten meter complete-melt scenario was not beyond the realm of empirical possibility, the onus is on you to provide that evidence, rather than engage in redirectional rhetorical sophistry.

And you can't provide it. Because authentic evidence for the truth of the untrue does not exist.

He cannot prove the truth of his false contention (that a 7 degree C rise in air temperature can cause a 4921.25% increase in ice melt rate), because it's false, and is now left with - reduced to - resorting to contending that others cannot demonstrate the falsity of his false contention 'to his satisfaction.' Who here thinks that, just like a contentious creationist, he will never be satisfied, regardless of what evidence is proffered?

If the contention were that he could post a message, he'd be posting a message to deny it.


Oh Sal, stop calling out to the peanut gallery... It is unbecoming.

I have posted links and evidence for why I think IPCC is lowball. But are you actually basing your scientific argument on the contention that if I were correct, I would have found even more links that you liked better? I am deeply impressed that you base all of your scientific knowledge on whether or not I find you links that are to your satisfaction. I shall have to write a paper about new methodologies based on my link finding... No doubt the other physicist will agree that that is a much stronger way to do science than theory and experiment.

Here we thought this was about making cogent arguments from scientific principles...

Just so we don't loose track. You have made a claim.

You claim that 7 degrees can not possibly cause the loss of the caps. You claimed it was something to do with force.

You need to back that up now Sal.

Force is defined as mass times acceleration. I don't see how that is part of the argument. What mass is accelerating? Please explain.

They are linked in a direct causal relationship.

And how does that relationship work? Could you express it in any sort of terms, either in mathematics or words?

Change in one entails change in the other.

How? By what mechanism? I am not playing dumb here Sal, tell me how you think this works.

But a 7 degree C increase in air temperature cannot cause a 4921.25% increase in ice melt rate.

Sal, you can't just say that, I am asking why? Justify your claim

If it could, you would have linked to evidence of it by now.

But I have linked to evidence and explained what the relevant points were. I have explained why. You just didn't like it. Now it is your turn to explain why it can not.

a 7C degrees temp increase and a 3 meter sea leve increase is a whacky prediction, result of a endless series of "what if" taken at worst case scenario. sure, it COULD happen. but it wont, and i wont wil the lotto next week, because it COULD happen but the chances it will are tiny, to all practical effects close to impossible.
is good to notice that the AGW keep postponing the point at which sea level will REALLY rise and temps will REALLY increase. sea level increased a inch the last century and temps have increased 1C. now next centuty sea level should rise 1000 inches, an extravangant value, and temps 7C? :-D

no, ice cap is melting only if you take into consideration an arbitrary interval of time that satisfies your assumptions. is a trick is done all the time to demonstrate every sort of quackery. same goes with temperatures. newslines like "the highest temperature ever" really piss me off. thats not EVER, thats ON RECORD, which is WAY different because records only go back a century or so and half of that temperatures were recorded with insufficient precision to demonstrate anything. and i wont get into facts the relocation of those measuring stations, heat island effects and so on.
as weather patterns changing, thats BS and you know it.

How is it impossible Sal? Really, if it is so obvious, you should be able to explain yourself. That's how science works. People make predictions and then argue about them. Justify your claim. It is not obvious to me and many others in the scientific community. So please buddy, just explain why it is so obvious.


You have done no such thing, and cannot. But, just like a creationist,

The only one acting like a creationist is you Sal. Just back up your claim.

you will say the equivalent of "well, HOW can that assemblage of base pairs possibly translate into a physiological trait?

Ummm, because base pairs contain coded information for strings of amino acids which then bend and fold into the proteins that make up all of the body's structures.

See that would be a scientific mechanism. What is your mechanism for how heat is related to ice melt such that 7 degrees can not melt the caps?

And when answered, you will say But I don't see it. So it mustn't be the case. It's the old argument from incredulity.

Can anyone say projection? The caps can be lost because we are observing a much higher rate of melt than predicted in IPCC. Then there are all of those other things I said about rates and non-linearities to explain what was missing from IPCC, that you didn't understand and say must not be the case.

HOW can it be that a 7 degree increase in air temperature doesn't cause a 4921.25% increase in melt rate?

YES HOW PLEASE TELL ME SAL!!! PLEASE PLEASE!!!

HOW can it be that dwarves are not fellating unicorns beneath the mountains of the moon?

Well because dwarves need air to breath. There is no air on the moon and they would need to open the helmet of their space suit to do it.

You see that is another example of mechanism!

You want details. And you will never be satisfied with them, and will always ask for more, ad nauseum ad infinitum. Now there are TWO gaps; explain them both!

"The first record of a large flood in the Venetian lagoon dates back to the so-called Rotta della Cucca, reported by Paul the Deacon[10] as having occurred on October 17, 589. According to Paul, all rivers with mouths in the northern Adriatic, from Tagliamento to Po, overflew at the same time, completely modifying the hydro-geologic equilibrium of the lagoon."

589, im sure AGW was in full swing already, with all those venetians driving SUV's and speedboats in the lagoon.

and anyway you are so busy studying your navel that you have, as usual, completely missed the point with the water levels in venice.

re: #902 LudwigVanQuixote

Actually before even that, I would like him to explain how ice melts at all from a change in temperature to start with. By what mechanism does a different temperature change the ice Sal?

Although I am not part of this discussion, I'll jump in anyway and give my non-expert impression of how it works:

Heat is our word to describe the level of molecular excitation in a substance. The more the molecules are bouncing around, the "hotter" it feels to us. What causes them to bounce around is extra energy in the electron orbits/cloud around the nucleus.

When there are two substances of difference excitation levels and different densities "touching" each other, then the laws of fluid dynamics say that there is an energy transerence from the high-energy high-pressure area into the low-energy low-pressure area. (This is the part I'm a little vague on because I never studied heat transfer or fluid dynamics.) But anyway just on common sense principles and daily observation one can see that high-pressure areas "flow into" low pressure areas -- or viewed from the other way, low-pressure areas "suck up" high pressure areas.

So what he have are two chemical substances -- a nitrogen/oxygen mixture we call "air", and a chemical made of two hydrogen atoms bonded to an oxygen atom that we call "steam/water/ice" depending on its level of excitation.

Famously, the "function collapse" points of H2O happen at 32 degrees and 212 degrees farhenheit: at 32 the liquid manifestation of the chemical spontaneously crystallizes, whereas at 212 it spontaneously evaporates. At those two precise points the equations describing the group behavior of the molecules collapse for each state and cease to predict properly how the chemical will behave. Hence, from our point of view we describe the evaporated over-212 version of the chemical as "steam" with a certain set of properties; the 32-212 version as "water" with different properties; and the sub-32 version as "ice" with yet different properties. (Needless to say, this is simplified, leaving out various variables.)

So, if the adjacent "air" (nitrogen/oxygen mix) has a certain energy level, it will reach a specific stable equilibrium after an energy exchange with any adjacent substance; in other words, the air will heat up the ice and the ice will cool down the air until they reach a chemically satisfactory equilibrium point after en energy exchange.

Now, to the melting part: If the air has sufficient energy and it's touching ice, then it will transfer enough energy to some of the ice to cause it to reach 32 degrees, after will the crystal structure will collapse and it will turn into the liquid form -- what we call "melting." But this drains energy out of the air, so it's not like one cup of warm air can melt an iceberg; you need a lot of "warm" air to "melt" a big hunk of ice.

Anyway, that's my understanding of the chemistry/physics of it.

As for whether a 7-degree celsius increase being sufficient to melt an iceberg the size of Antarctica -- I have no clue.

Zombie you rock! That is exactly correct. The important point to determine if you have enough energy to do that is first off if the entire atmosphere were heated enough by seven degrees, would that have enough energy in it to melt the ice. If not, would that + the hotter oceans do it? If not would that plus the hotter oceans and the sun still beating down on even less ice and warming the air and the oceans even more do it?

That is the whole sub point.

Now it turns out that heating all of the atmosphere of the Earth by seven degrees is actually an enormous amount of energy. You could calculate the mass of the atmosphere times the specific heat of air times the seven degree change. That would give you the energy in the atmosphere from the heat. The you could calculate the mass of ice and the heat of fusion of ice and see if that amount of energy (needed to melt the ice) is less than the heat energy gained by the atmosphere.

So it turns out that the there is enough energy to melt the ice if you throw in the feedbacks.

ludwig, you insist in pushing a theory based on extravagant assumptions. i will anyway tell you somerthing i have actually seen.
as you might have heard, due to global warming LOL we had massive snowfall in europe last winter. this has triggered some large snowmass avalanches from the alps. i can see one of these from the road i use to go from switzerland to italy. one large one occurred around april. large is relative of course, it is large compared to me, around 400ft long and wide, and maybe 200ft tall, but tiny compared to south pole.
now, we are in august and we have in that place temperatures of well over 25C during the day, which is way above ice melt temperature of 0C.
well, you can still see a quite large amount of snow there.
you probably have not much familiarity with nsow and ice apart with what you find in your freezer, otherwise you would know that any amount of snow/ice takes very long to melt even in temperatures way higher than melting point. this because snow/ice has a very high albedo and doesnt therefore absorb energy easily. arctic ice melts rapidly because it is melted by the warm water in which it floats. the seawater at the pole is just slightly above melting point of ice and energy is transmitted from water to ice through conductivity, which is orders of magnitude more efficient than radiancy. in fact, if you had any familiarity with ice apart the cubes floating on your whisky, you will know that a rainfall can melt snow hunreds of times faster than warm days.
so forget about soutnh pole melting. that would take millennia even if temperatures raised not 3C but 30C

Who here believes that? Who actually believes that that is indeed the case?

Nobody; not even Ludwig. Even if he renders it impossible to explain 'to his satisfaction' why it is not so.

And it IS indeed the same thing because he is claiming that a gradual 7 degree C increase in air temperature would completely melt the Greenland, Arctic and Antarctic ice caps in the next century, causing a ten meter rise in sea level, when the past century only saw an 8 inch increase. Ten meters is 393.7 inches,or 49.2125 times 8 inches, which translates to a 4921.25% melt rate increase for it to happen. The change in melt rate would have to be the same for the glaciers as for the ice cubes, since the temperature change is the same. The only differences are bigger ice cubes taking longer to melt. But if a sea level rise of only 8 inches increases to ten meters as a result of a 7 degree C temperature increase, then an ice cube that would take 49 minutes to melt at one air temperature would have to melt in a single minute if that air temperature was raised by only 7 degrees C, for Ludwig's contention to be true.

And I'm being generous in my example; I'm allowing the second cube to be bathed in that warmer air from the get-go, whereas the global ambient temperature only gradually rises to that point over the next century.

Take note, Ludwig; that's what's known as a valid analogy.

921 gianmarko  Mon, Aug 10, 2009 3:21:24am

south pole is not going to melt at all with a 7C degrees temp increase. and anyway, you all seem to miss one important point: sea level increase is maily caused by volume expansion and not by ice melting. and all sea level icrease predictions start from the assumption that temperatures will keep increasing, which is speculation.

...

So it turns out that the there is enough energy to melt the ice if you throw in the feedbacks.

But...

At the South Pole, there is very little direct photons from the sun striking the frozen H20 molecules of Antarctica. (Which is why it's all frozen in the first place, naturally.) They're coming in at an extreme oblique angle, and there is usually atmospheric interference (aka "clouds") preventing the sun's energy from hitting the ice directly. I don't think that "direct sunlight striking and melting the southern polar ice cap" would play any significant role.

Furthermore, the oceans only lap around the edges of Antartica. Considering how big the interior is and how thick the ice is, it seems that the warmer ocean water is only directly touching a tiny tiny percetage of the overall ice on Anarctica.

No, it seems that the atmosphere -- not the oceans and not the sun's photons -- is what principally touches/chemically-influences the ice at the southern pole, because the ice is mostly on land -- cloud-covered land most of the time. I don't have exact percentages, but off the top of my common-sense lobe I would say that the temperature of the atmosphere is what is going to be the direct cause of 99% of the warming/melting effect (or lack thereof).

Of course, the sunlight and the oceans directly impact the atmosphere itself, and through that medium can effect the ice, but once again that means it's the air/gas that's doing the melting, while the water and sun only serve to heat up the air.

Also keep in mind that as the atmosphere transfers its energy to the ice, the "temperature" (our human term for energy level in the gas) goes down coincident with its energy draining away, so that although the ice is heating up, the air is at the same time cooling down as a consequence. Which seems to lead to an "anti-runaway effect" or a feedback loop that slows down the melting as it progresses.

Whether this has any bearing on or underwhelms the other feedback effects (less reflectivity, etc.), again I have no clue. Just tossing out some notions for consideration.

923 LudwigVanQuixote  Mon, Aug 10, 2009 3:27:53am

re: #920 Salamantis

The change in melt rate would have to be the same for the glaciers as for the ice cubes, since the temperature change is the same. The only differences are bigger ice cubes taking longer to melt.

Ummm Sal, one point is that as they break up, the reflect less light, and more heat gets trapped in the atmosphere that can melt them.
Another point is that they do not break up in regular manners and they do not just melt smoothly like ice cubes. So this is completely wrong.

But if a sea level rise of only 8 inches increases to ten meters as a result of a 7 degree C temperature increase, then an ice cube that would take 49 minutes to melt at one air temperature would have to melt in a single minute if that air temperature was raised by only 7 degrees C, for Ludwig's contention to be true.

Sorry Sal, I'm pretty good at this math stuff, and I just don't see how you calculated that. Could you explain that please? Does mass come into play at all here? I mean does it matter how much ice and how much air/water is involved? What about surface area? Does that matter?

And I'm being generous in my example; I'm allowing the second cube to be bathed in that warmer air from the get-go, whereas the global ambient temperature only gradually rises to that point over the next century

.

When did you mention bathing in water and how does that affect your calculation?

Take note, Ludwig; that's what's known as a valid analogy.

Ohh... I'd call that lots of things Sal, but a good analogy... no... probably not.

Sal, I am not trying to make an evil reducto for you. I am looking for a cogent mechanism.

Let me help you... A proper argument would go like this...

Polar ice melts like this...

The hotter air at Seven degrees would melt affect the polar ice like this...

Therefore, Seven degrees could not do it.

That's the exact point I was also trying to make in the 2nd-4th paragraphs of my comment #922. At the north pole the sea water touches the ice all over because the ice is floating on it. So the melt rate is much much faster. The Southern pole ice is insulated from the ocean and from the sun, so is much much more difficult to melt.

I think Zombie and I already did. As Zombie just demonstrated, the effects of the sunlight and ocean are overwhelmed by the effects of the air temperature. And as I just demonstrated, considering what has happened in the last century, a 7 degree C increase doesn't get it done.

Not for an ice cube. Not for the Greenland Ice Cap.

re: #930 Kevlaur

Howdy all... somewhat longtime reader, new registrant. I'm a skeptic; definitely. The earth is how old? Depends on whether you're a creationist, certain type of Christian, etc, etc... So, we have just over a 100 years worth of records and how old do all of this different categories of people think the earth is?
I'll have to admit... I didn't read the articles.

Actually, the age of the Earth is not dependent on the belief systems of its inhabitants.

The Earth is 4.54 billion years old, "whether you're a creationist, certain type of Christian, etc, etc." It's the same age for everybody.

And yes, we only have a century or two of direct measurements; but we can do some pretty good extrapolation of what the temperature was likely to have been way way back in the past.

(And what that extrapolation tells us is that the Earth's temperature never stays the same -- it is always in flux. So what's happening now is basically "par for the course," whatever its cause.)

What it all boils down to for conservatives, especially the Bible-thumping ultries, is that scientists are trying to shove evolution down their already Bible-filled throats.

They therefore don’t trust scientists to tell them anything, particularly anything they disagree with. So they oppose almost all science unless it’s something patriotic, like the space program.

In their minds, global warming CAN’T be true because it’s postulated by all those liberal scientists who believe we came from monkeys. And facts? Please don’t ever talk to them about facts. They don’t believe in facts either.

re: #831 zombie

Let's try not to make sweeping assumptions about what each other knows and does not know. I made no claim to be a publishing industry maven, though I am familiar with some of the difficulties involved in getting a book published. You, on the other hand have made broad claims about a book's contents and an author's motivations and agenda, yet have not produced an argument, a book, an article, or even a webpage to back those claims. I find it hard to believe that no one who shares your view has written anything you would consider support for your contentions. Bloggers of all people know that the published book is not always the currency of knowledge's state of the art. Finding critiques of GG&S is not that hard to do with a simple web search, but I cannot tell from looking at them whether they are the opinions _you_ share that you consider the strong rebuttals and smoking gun of author bias, so I cannot tell whether I would agree with your statements.

Let me also say, that I think Diamond does fail to account for certain social phenomena, and the power of individuals and small ideological groups to affect the course history and civilization. But that's fairly late in the game. The biological, and geological foundational arguments in his book look to me very hard to challenge on ideological grounds.

What good it would do to publish or present a cogent, well researched rebuttal? How about raising the level of discourse? How about presenting a strong (should it indeed turn out to be strong) challenge to a prevailing theory? If you are indeed *correct*, how about replacing Diamond as the prevailing theory? And if, in the research it turns out your assumptions were not exactly right, you learn something as well. I add this last because even though you know his work is wrong and biased, it would still take you years of research to show that. That sounds like either a presupposed conclusion that wants, but doesn't yet have real support, or a black and whit statement of something that is in fact quite a number of shades of grey.

It is indeed frustrating to hear someone claim to be able to prove a point, not prove it, yet still use that claim as an argument from authority. It's the last part that is the most frustrating, because I cannot simply accept your authority and move on to the other points you want to make. GG&S is, after all, a sideline away from the main discussion of this thread.

Just as there was cannibalism at the Superdome during the Hurricane Katrina flood. Except there wasn't.

"... I really fail to see how switching over from fossil fuels to cleaner energy sources counts as clear eyed genocide. Could you please explain the concept to me?"

Because the few energy sources powerful and abundant enough to provide the refrigeration and transport services needed to feed a single modern nation, such as the US, cannot be made any cleaner than they already are. Solar and wind cannot produce power on demand to meet needs that shift throughout the day like coal, oil, gas, and nuclear energy can, even if they were able to generate it in sufficient quantity (which is decades away still, if not centuries). Global warming may kill millions, but bringing about the end of industrial agriculture definitely will.

What's is most disturbing to me here about Charles' posts are not that he is buying into AGW, but they way he is doing it. Telling people who disagree they are wrong.

This is the denial of workable theories for climate change that do not involve AGW, and I find it to be the common attitude among AGW proponents. They must be right - no use looking at any other explanations.

I looked at AGW in detail with everything that my MIT education gave me, and my opinion is that the emperor has no clothes. The alternative theories I have researched explain things just as well. Of all the theories (AGW + alternatives) none them are perfect and all have been partially debunked and modified as things go with any theory.

There's a possibility that AGW is the basis for the correct explanation, but I believe strongly it is just a bit player. Could I be wrong? Sure.

Anyway, I expected more here. I do no begrudge anyone saying they have looked at AGW and saying they believe it is happening. Fine. But when you do not include the possibility you are wrong, it justifies the classification of AGW as a religion of its own.

re: #862 LudwigVanQuixote

NO, I am trying to educate you one point at a time about the science.

Do you see why the sun is what is warming us ultimately?

Do you see that the sun's output has not changed and therefore it can not be irradiance causing the warming? This is really basic logic.

Why don't you see this?

What part of "heat is only part of what the Sun puts out" am I not being clear on? Ever hear of "solar wind"? Spare me the arrogant nonsense about how you are trying to "educate" me, and about "basic logic". You're not even paying attention, or are being intentionally obtuse. Either way, you come off exactly like a religious evangelist (not that I'm surprised).

BTW, the solar irradiance DOES vary somewhat - some fraction of a %, IIRC. But nobody claims that it varies enough to directly explain the climate change seen over the last century, so this concept you're clinging to so desperately is a total strawman.

Then, again, nobody claims that the elevation of CO2 levels directly has caused significant changes in temperature, either. The models depend on an amplifying effect where a small increase in temperature caused by the CO2 causes changes in water vapor and cloud levels. Unfortunately for the AGW alarmists, this critical part of the model isn't holding up to scrutiny. I didn't notice that being addressed on the web page, BTW, although I could have missed it.

As for consensus, Balian1193 , scientific consensus is not a couple dozen, or even tens of thousands guys in white coats going "Yeah! Right on!" Its hundreds, thousands of individuals and groups following different lines of questioning and gathering different pieces of evidence that paint the picture. And, to abuse the metaphor, it's much more like an impressionist or pointillist painting than anything like photorealism. The end picture is still pretty clear, even if it's not pretty.

re: #955 MKelly

Despite active efforts to answer these questions, the following pervasive myth arose: there was a consensus among climate scientists of the 1970s that either global cooling or a full-fledged ice age was imminent. A review of the climate science literature from 1965 to 1979 shows this myth to be false. The myth's basis lies in a selective misreading of the texts both by some members of the media at the time and by some observers today. (Thomas C. Peterson, William M. Connolley, and John Fleck, The Myth of the 1970s Global Cooling Scientific Consensus,Bulletin of the American Meteorological Society)

New Scientist from 2007

There is a great deal of uncertainty, though. The warming could be a regional effect. And recent results from the thermal imaging system on the Mars Odyssey probe suggest that the polar cap is not shrinking at all, but varies greatly from one Martian year to the next, although the details have yet to be published.

We understand Mars' climate orders of magnitude more poorly than Earth's, and Pluto's even less. I would be very circumspect about translating observations from one planet into conclusions about another.

re: #907 LudwigVanQuixote

Sea levels are really rising now. Ice caps are really melting now. Weather patterns are really changing now.

At what point is now not sufficient?

Um, sea level was showing a rise of about a foot per year, but is currently in something of a stall. The predominent effect has been the water expanding or contracting with temperature. It's been stalled lately because global warming has effectively been on hold for about a decade.

The ice caps are doing fine. Antarctica is the important one, if you're concerned about sea level, because the ice is on land there. Ice over water, such as in the Arctic doesn't effect sea level (using that High school pysics you like to talk about). Last I heard, Antarctica was actually gaining some ice, ironically because the surrounding ocean is a bit warmer these days, making it snow more. The temperature down there would have to rise by way, way more than even the crazier alarmists have been claiming, in order to get the Antarctic to melt. The vast majority of the ice is way, way below freezing ALL the time.

Try to impress some chumps by throwing around terms like "specific heat" and "heat of fusion" all you want, but normally it has to actually get above freezing for ice to melt.

The Artic sea ice took a big dip two years ago (mostly due to changing currents), but has rebounded some since then. Interestingly, we still haven't seen open water at the North Pole in the summer, despite dire-sounding AGW-laced predictions of such. The funny thing is, there are photos of Navy subs in open water at the North Pole from the 60s. So the joke is that even if the North Pole DID melt, it wouldn't be out of the range of natural variability. The fact that it hasn't melted in recent years tells you all you need to know about the ice caps supposedly melting (namely, that they're not).


As to all this endless banter about melt rates, I happen to know a thing or two about the subject matter. It seems to me that the rate of heat transfer from the air to the ice would be proportional to the difference between the temperature of the two. Air is far less dense than ice, of course, and so as it gave up this heat it would cool quickly. So the physics involved have more to do with the heat equation (a partial differential equation) than anything someone would study in High School, and that's just for the simple "point" answer, which ignores how the given point effects (and is effected by) the surrounding area. So it all gets extremely complex in a big hurry. Besides, the ice would first have to rise to the melting point, and then the "heat of fusion" - which is very high for water - kicks in. It would take a lot to melt the ice caps.

Ice does not have to rise above 0°C to start disappearing sublimation from solid to vapor is a known and significant phenomenon in the antarctic, where despite being covered in the white stuff, has vast areas of such low humidity as to be considered hyper-arid. Such low moisture content in the atmosphere allows significant rates of sublimation.

Now, I don't know off hand how sublimation rates are effected by the current climate variations, and that is not a point I intend to argue here. I did feel the need to point out that melting is far from the only way to get rid of land-cover ice.

re: #914 zombie

...Heat is our word to describe the level of molecular excitation in a substance. The more the molecules are bouncing around, the "hotter" it feels to us. What causes them to bounce around is extra energy in the electron orbits/cloud around the nucleus.


As long as we're trying to be scientific here, what you're describing here is called "temperature", not "heat". Heat is a form of energy, and it is when you have more of it that you get this higher "level of excitation", but the result is that it gets "hotter", as you say, which is an increase in temperature.

When there are two substances of difference excitation levels and different densities "touching" each other, then the laws of fluid dynamics say that there is an energy transerence from the high-energy high-pressure area into the low-energy low-pressure area. (This is the part I'm a little vague on because I never studied heat transfer or fluid dynamics.) But anyway just on common sense principles and daily observation one can see that high-pressure areas "flow into" low pressure areas -- or viewed from the other way, low-pressure areas "suck up" high pressure areas.

The simple way to say this is that heat (which is energy) flows from the hotter temperature body to the colder one. As a rough rule (as I said in another post) the flow of heat is proportional to the temperature difference. But keep in mind that as this happens the temperature of the two bodies can change.

So what he have are two chemical substances -- a nitrogen/oxygen mixture we call "air", and a chemical made of two hydrogen atoms bonded to an oxygen atom that we call "steam/water/ice" depending on its level of excitation.

As I learned from helping my kid study High School chemistry last year, the air is properly called a "mixture" (a homogeneous one, at that), but not a "substance" (although the water is). (Just FYI, while we're educating ourselves.)

Famously, the "function collapse" points of H2O happen at 32 degrees and 212 degrees farhenheit: at 32 the liquid manifestation of the chemical spontaneously crystallizes, whereas at 212 it spontaneously evaporates. At those two precise points the equations describing the group behavior of the molecules collapse for each state and cease to predict properly how the chemical will behave. Hence, from our point of view we describe the evaporated over-212 version of the chemical as "steam" with a certain set of properties; the 32-212 version as "water" with different properties; and the sub-32 version as "ice" with yet different properties. (Needless to say, this is simplified, leaving out various variables.).

Actually, I'd say it was overcomplicating the matter for this context, but OK...

So, if the adjacent "air" (nitrogen/oxygen mix) has a certain energy level, it will reach a specific stable equilibrium after an energy exchange with any adjacent substance; in other words, the air will heat up the ice and the ice will cool down the air until they reach a chemically satisfactory equilibrium point after en energy exchange.

Yes (if the air is warmer, anyway), but only if nothing changes, and it's allowed to progress to that state (as in a closed, insulated system). But this is not the case in nature, and so it gets complicated.

Corale looking back now we see that, but at the time there was great concern about an ice age.

As the linked article says, that concern did not come from the scientific community, which was your claim. It was not consensus.


Maybe to have a discussion we should agree on somethings that not debatable. Such as carbon dioxide is absolutely necessary for life as we know it to exist on earth. It is not a pollutant.

Too much of it ain't good. Look at Venus for the extreme case.

re: #914 zombie

...Now, to the melting part: If the air has sufficient energy and it's touching ice, then it will transfer enough energy to some of the ice to cause it to reach 32 degrees, after will the crystal structure will collapse and it will turn into the liquid form -- what we call "melting." But this drains energy out of the air, so it's not like one cup of warm air can melt an iceberg; you need a lot of "warm" air to "melt" a big hunk of ice.

Yes, but you make it sound like it instantly turns from ice to water. It takes a lot of energy to convert ice at 32degF to water at 32degF. Note, also, that because air has such a low density, it would take a huge volume of air to transfer the energy to a relatively low volume of ice/water.

...Anyway, that's my understanding of the chemistry/physics of it.

Not bad, but efficient use of the correct terms would have simplified the discussion a LOT.

As for whether a 7-degree celsius increase being sufficient to melt an iceberg the size of Antarctica -- I have no clue.

The increase would have to raise the air temperature enough so that it actually gets above freezing. I would think that this is not the case for most of Antarctica year 'round. In areas where it would get above freezing for part of the year, it would still take a while for the ice to melt, so not all of it would melt during that season. Then some ice would re-form during the long winter anyway, so it has that working against it.

So, Antarctica would not melt, but a 7degC climb would certainly cause significant loss of ice, and some rising of sea level. Antarctica has 90% of the world's ice, BTW.

But even the IPCC isn't talking about an increase that large, at least in THIS young century.

I would also hope that you're still weighing evidence as it comes in and have the ability to change your mind as facts continue to accumulate. For some - including the vast majority in the field, the weight of evidence reached the tipping point long ago. For you it may take longer - or never. That's the way it goes.

re: #922 zombie

I thought that was pretty good, but can add one extra bit to the physics. It turns out that the Sun mostly heats the ground, and it's the warm ground that heats up the air. But how much the ground heats up the air depends, in part, on how warm the air is to start with. It sounds like you're grasping some of the complexities just fine, though. It's already pretty complicated, even without getting into how "this" patch of ground (or air) interacts with the ones it's next to.

But the big problem with the celebrated climate models is that they expect positive feedback from the interaction of CO2 and H2O, and that appears to be invalid. It's that little detail about validating models that they like to ignore.

981 Optimizer  Mon, Aug 10, 2009 10:56:38am

re: #925 LudwigVanQuixote

Be careful, warm water also melts the ice. Also you need to take currents (both air and sea) into account for the full story.

In the Antarctic, warm water also creates the ice! It puts more water vapor into the air, which condenses as it flows over the frozen antarctic ice cap. Then the snow gets packed, under its own weight, and there's more ice!

Down there (where 90% of the ice is), it wouldn't make the air cold enough to melt a significant amount of ice.

If you're truly interested in this issue, read those reviews very very carefully. Each point in each of the reviews raises serious challenges to Diamond's theories -- which if explored fully would absolutely dismantle piece by piece his entire theory.

re: #932 zombie

Actually, the age of the Earth is not dependent on the belief systems of its inhabitants.

The Earth is 4.54 billion years old, "whether you're a creationist, certain type of Christian, etc, etc." It's the same age for everybody..)

Good point, but I think they meant "How old do you think it is?" We don't have to get people going on those "you must be a Creationist" ad hominems, do we? Geez, I think Charles was starting to imply that I must be a Creationist the last time he put this kind of thread up, and that's too funny!

And yes, we only have a century or two of direct measurements; but we can do some pretty good extrapolation of what the temperature was likely to have been way way back in the past.

I think it's relevant to point out that the measurements of "a century or two" are pretty bad (even today, excepting satellites). "Estimation" is the correct term (vs. "extrapolation") regarding older temperatures, but I think people give those too much credit. Proxy measurements were not intended to establish the temperature of the Earth to a fraction of a degree, and I seriously doubt that estimates of tempertures in centuries past are very accurate. Sure, they'll tell you that it was 10deg warmer or colder (with SOME level of confidence), but I would expect that records such as Vikings growing vineyards in Greenland would be more reliable (and even THOSE wouldn't tell you to a fraction of a degree).

Just because a computer prints out a number to a certain number of decimal places, it doesn't mean it's accurate to that many decimal places. Or accurate at all, for that matter - and that's the really big point. [Not arguing with zombie here, BTW]

(And what that extrapolation tells us is that the Earth's temperature never stays the same -- it is always in flux. So what's happening now is basically "par for the course," whatever its cause.)

Not only that it changes, but that the temperatures being experienced are not unprecedented. And we just have to look at the record of Vikings in Greenland, and subs surfaced at an ice-free North Pole in the 60s, to see that.

But even if they did this, you would still need a multi-variant regression to pinpoint a anthropogenic cause and rule out such errors as collinearity.

However the warmest years on record are from the mid 1800's, Hotter than now. So it was hotter in the mid 1800's, then cooler, now it's warming again?

It is interesting that everyone wants to try to convince the "deniers" or "skeptics" that the consensus is that a molecule that is vital to life is a pollutant, must be contained/regulated/taxed, and that this minuscule change of one molecule per ten thousand is enough to bake the atmosphere, however, when a solar cycle has fizzled (24) and is not taking place, these same "climatologists" mock the fiery yellow ball.

Firstly, I am a physicist and an entrepreneur. I am not a climatologist, but have been following this topic since I first read Hansen's statements in 1989. I studied it in graduate school, then left it because?-it was just as political then. You have to look at this from a higher elevation. There are a lot of models out there, computer algorithms, and a lot of people beating each other for funding. The scarier the model, the more funding.

I used to think that the arguments of the CO2 crowd were right. Then I was in a discussion with a solar physicist, who passed away a number of years ago. His comments were what changed me; made me reflect back on my physics studies: rates and orders of magnitude.

The sun dumps an amount of energy in solar radiation that is 100,000 times greater than what all of humanity generates IN ONE SECOND. (Sun: ~1.5 x 10^22 J/day, Humans: ~7-8 x 10^19 J/YEAR. Or 1.7x10^17 Watts [Sun] vs ~2x10^12 Watts [Human]) Again, that is pure solar energy compared to the vast array of energy types used (burned, collected, fissiled, etc). This number for Humans does not include the Heat loss that is typical in all energy produced, that is the laws of thermodynamics and cannot be violated.

So if the solar output of the sun varies by 1/1000 of a W/m2 people tend to think that is not an issue. It is an issue. There are plenty of articles linking solar spots versus energy flux variability as well as incoming flux variability versus atmospheric temperature. This is real science speaking from real measurements of real experiments that are being scoffed at by a bunch of computer nerds manipulating data for government funding. And not one of their models, out of what is it...35? works to predict temperature.

The sun has not had sunspot activity in over a year. Since this time, there has been record weather in colder recordings. New England has seen it, the Midwest has seen it, Chicago has seen it, and so on and so forth. I have been reading several of the posts and it is blatantly clear that a large majority here do not understand the basic laws of thermodynamics let alone physics. That scares me a lot.

Seriously, if you are going to take someone's written oratory as face value, and their conclusions are that you should be shackled from any freedoms on your choice of fuels, let alone what temperature you will have to set your thermostat, or that the oceans will rise umpteen feet (simple math problem, give it a try), etc. And all of you are buying it because some Hollywood nut or a bloated failed politician made a fancy movie (ripe with flaws) and told you so. You really need to take a step back and think. Think real hard and don't give up until it hurts. Mankind has never been so lock step on a "belief". That is what AGW is and so is the Easter Bunny. Science is not a bunch of computer models manipulated for your fears, it is real measured data compared to real theory. Theory must be disproved before it is valid. Laws cannot be broken, just regions where the law is inferior (e.g. gravity at the atomic level). This AGW is hooey until the theory can be solved without computer models.

Again, let's see some dialog on the zealotry of AGW and why it is silly.
My prediction: this coming winter of 09/10 will be very cold. Very, very cold. Colder than the past winters.

Ice does not have to rise above 0°C to start disappearing sublimation from solid to vapor is a known and significant phenomenon in the antarctic, where despite being covered in the white stuff, has vast areas of such low humidity as to be considered hyper-arid. Such low moisture content in the atmosphere allows significant rates of sublimation.

Now, I don't know off hand how sublimation rates are effected by the current climate variations, and that is not a point I intend to argue here. I did feel the need to point out that melting is far from the only way to get rid of land-cover ice.

Yes, there are a number of additional effects that can be talked about. Just how deep do we want to go here? Sublimation would certainly occur, although I have to wonder how "significant" it is, with the Sun being at a pretty low angle down there. The effect of albedo has also been mentioned. As I've said elsewhere on this thread, this all gets pretty complicated - even for a SINGLE POINT on the Earth, and I couldn't tell you if a model exists that could predict even THAT within a fraction of a degree.

Oh, but the point about how arid it is is kind of ironic. It's arid because it's really, really cold! We're talking about ice caps supposedly melting, remember? Talk about trying to "have it both ways"!

re: #986 Jimmah

Earlier you made the bizarre statement :


'Carnage and Culture' is published by Doubleday, a division of Random House.

Carnage and Culture was not actually written to debunk GG&S; it just happened to present an alternative theory about Western dominance. Hanson was not thinking "I want to debunk GG&S!" as his motivation for writing the book. It was simply his elaboration on an earlier book about military history. It just so happened that his thesis challenged one of the many theses in GG&S.

Carnage and Culture was a surprise hit -- I think the publishers originally saw it as just an academic book by a well-respected historian who had a built-in fan base of a few tens of thousands of followers -- enough to make the book profitable within its limited market. I think the publishrs were a bit taken aback by it selling more widely.

I also think they didn't exactly realize that C&C would be held up by some readers as a component in the culture wars. And I have the feeling that if Hanson had barged into the Doubleday office and said "I want to debunk GG&S with my new military history book! I hate liberals! Publish it!" they would have most likely not published it.

Also, C&C is not entirely pro-Western, so I think the publishers liked the fact that Western armies were depicted by Hanson as amoral killing machines. That was sufficiently in line with what they like to see.

It is possible to get "counter-intuitive" (i.e. conservative) themes into major books -- you just have to do it in "stealth mode." People like Michelle Malkin can't get a foot in the door at the major houses because she is apologetically "in your face" with her conservative activism. VDH is more staid and soft-spoken and has that professorial reassuring air.

Now, obviously, it's not like there is a blacklist against all conservative thought at all major publishers. Perhaps I over-enthusiasticlaly stated my case. Put it like this: If you are not a celebrity and not an established academic star or well-known pundit, and you approach a major NY publisher with a book overtly and aggressively "conservative" or "right-wing" in thesis -- your chances of getting published are very slim. You'd have to go to smaller publishers that specialize in conservative titles.

But if you are already well-known and have to a certain degree been accepted into the mainstream, you can include conservative memes in your book and still get it accepted, just so long as you aren't all aggressive about it.

Hence, books like "Freakonomics" can have chapters with data that supports the conservative argument (among other chapters that don't).

Coracle I never used the word scienitific just consensus. But again "did anyone who now believes in global warming believe in coming ice age back then"?

You asked exactly this:

Those of you that believe in human caused global warming a question: did you believe we were going into an ice age in the 70's? Consensus had us going into one.

Speaking only for myself, no. I did not believe that an ice age was imminent in the 70's. I also know personally no other scientist who did. My linked article tells you why. And I would also argue that that myth had just as much "general" consensus at the time as it had scientific consensus. I.e. none.

PV=nRT Venus has a pressure 90+ of earths given that, we would be hot as Venus if our pressure went up. Actually possibly hotter due to the difference in triatomic and bi-atomic molecules.

Venus is an example of a runaway greenhouse effect. The temperature/pressure extremes came about in part as positive feedback once the temperatures rose beyond a certain point. I do not contend "OMG we're gonna turn into Venus!!", but I do point out there is a point where CO2 ceases to be our friend.

As for CO2 being necessary for life and at this level (380ppm) is not a pollant. Yes or No.

My first Biogeochemistry text book was published in 1991. It had a plot of PPMV CO2 from 1958 to 1988. where average CO2 was just under 350. 380 would have blown the top off the plot. The knowledge that biomass and fossil fuel burning - i.e. CO2 pollution - is the source of this rise is older than that.

re: #995 jdubya

Lo... I have ben summoned.

As a fellow physicist, I would love to discuss this with you.

While I agree it seems intuitive, that solar variations could in principle have a large effect, I think that you have to then go and look and see if such an effect has been recorded. It turns out that using sunspots or other solar activity has never been a predictor. The numbers you have given may seem daunting but the variations in overall irradiance are very small compared to the effects we see on Earth.

This link from AIP has a good history of why most physicist in the business discount solar activity as a driver for climate change.

[Link: www.aip.org...]

By the 1990s, there was a tentative answer: minor solar variations could indeed have been partly responsible for some past fluctuations... but future warming from the rise in greenhouse gases would far outweigh any solar effects.

I can't believe this thread is still going strong!

It's a contentious issue, especially among people like me who are generally convinced that AGW is happening, but remain unconvinced that our leaders are taking action against it, and are more convinced they're using it to implement a pile of social programs that are ineffectual at best, and more likely intended to increase the damage for the sake of quelling dissent.

1012 gianmarko  Mon, Aug 10, 2009 12:07:26pm

just to make a few things clear.
i dont think the circumstancial evidence for AGW is compelling enough for anyone in his right mind, and the doom and gloom predictions are just laughing material. still, i'd give up fossil fuels right now if i was given an alternative form of energy at least as usable and as expensive. and trust me, fuels here are already way too expensive.
this because i am a real environmentalist, not some whacko who wants to reduce global population to 2 bln or less through scarcity of energy and establish a form of world communism using the energy lever.
yes i would miss the sound of my motorbike, but is a small price to pay to have a cleaner planet.
however, while i still have several working neurons, is out of the question that i give up fossil fuels, and with them my welfare and the welfare of my family, in favour of pie in the skie stuff like wind or solar. really, folks, be my guests, come here in my garden next winter and see if you can survive it using just the sun and the wind.
so, dear AGWers, give it up. you either give me cheap, abundant energy, or there is no deal. is mine and my loved ones life we are talking about here. and anything goes, when so much is at stake.

1013 LudwigVanQuixote  Mon, Aug 10, 2009 12:09:11pm

In fact to really talk about the sun some more...

[Link: www.aip.org...]

AIP is the American Institute of Physics

However, rough limits could now be set on the extent of the Sun's influence. Average sunspot activity did not increase after 1980, and on the whole, solar activity during the half-century since 1950 looked little different from the half-century before. The continuing satellite measurements of the solar constant found it cycling within narrow limits, scarcely one part in a thousand. As for cosmic rays, they had been measured since the 1950s and likewise showed no long-term trend. Yet the global temperature rise that had resumed in the 1970s was accelerating at a record-breaking pace. It seemed impossible to explain that using the Sun alone, without invoking greenhouse gases. "Over the past 20 years," a group reviewing the data reported in 2007, "all the trends in the Sun that could have had an influence on the Earth's climate have been in the opposite direction to that required to explain the observed rise in global mean temperatures." The most advanced computer models now allowed for a presumed influence of solar variations on climate, and they calculated that since the 1970s that influence had increasingly dwindled in significance as compared with the rising effects of greenhouse gases. The modelers got a good match to maps of recent observed climate changes when they included the effects of the gases, but not if they tried to attribute it all to the Sun. For example, the stratosphere was cooling, which was exactly what models predicted would result from the greenhouse effect, but the reverse of what should result from a solar influence

re: #979 Coracle

You call yourself a skeptic, so I might assume you wouldn't be inclined to call someone who supported the extreme of either side absolutely right - or wrong. I would also hope that you're still weighing evidence as it comes in and have the ability to change your mind as facts continue to accumulate. For some - including the vast majority in the field, the weight of evidence reached the tipping point long ago. For you it may take longer - or never. That's the way it goes.

In the history of science, "the vast majority in the field" have been wrong many, many times. This is really just an appeal to authority. There are thousands of scientists, engineers, meteorologists in the field and related fields that remain skeptical. Also many people in the field are invested in AGW for many reasons - political, financial, reputation. There is something of an Enviro-Industrial-Political complex at work. In a situation like this, we must be very careful of what we declare "facts", and more skepticism is called for, not less.

I suspect that over the next 10-20 years, it will become more and more obvious where the climate is headed.

re: #995 jdubya

It is interesting that everyone wants to try to convince the "deniers" or "skeptics" that the consensus is that a molecule that is vital to life is a pollutant, must be contained/regulated/taxed, and that this minuscule change of one molecule per ten thousand is enough to bake the atmosphere, however, when a solar cycle has fizzled (24) and is not taking place, these same "climatologists" mock the fiery yellow ball.

I particularly enjoyed the phrase "mock the fiery yellow ball".

... You have to look at this from a higher elevation. There are a lot of models out there, computer algorithms, and a lot of people beating each other for funding. The scarier the model, the more funding.

What's scarier still is when intelligent and influential see the output of these models, and start to taut them as "scientific fact".

... There are plenty of articles linking solar spots versus energy flux variability as well as incoming flux variability versus atmospheric temperature. This is real science speaking from real measurements of real experiments that are being scoffed at by a bunch of computer nerds manipulating data for government funding. And not one of their models, out of what is it...35? works to predict temperature.

I had always heard (even from the skeptic side) that the variation of flux could not directly explain the temperature variation, but you've got me wondering about that. Scary, though, how the work of this type of "computer nerds" is being called "scientific fact" in intelligent discourse and official policy meetings.

The sun has not had sunspot activity in over a year. Since this time, there has been record weather in colder recordings. New England has seen it, the Midwest has seen it, Chicago has seen it, and so on and so forth. I have been reading several of the posts and it is blatantly clear that a large majority here do not understand the basic laws of thermodynamics let alone physics. That scares me a lot.

...My prediction: this coming winter of 09/10 will be very cold. Very, very cold. Colder than the past winters.
But that is just a guess.

The theory that it's more (or all) about solar cycles is having a very rare opportunity to really see if it holds water. This could get REAL interesting. If the theory holds up, I hope the results become obvious before anything too drastic is acheived by the various governments. But in recent decades, activists usually manage to have their way BEFORE the results come in.

re: #988 Charles

Then you don't understand my position, because I'm still highly skeptical about many of the proposed policies to address AGW. What I have concluded is that the science demonstrating climate change is very convincing.

Policy is another matter entirely. But we're never going to properly address that while one side is in complete denial of the scientific facts.

Saying that one side is "in complete denial of the scientific facts" is just another way of declaring "I am right and you are wrong."

Many of the "facts" of the matter are in dispute. Do you acknowledge the weakness and immaturity of the computer models? Do you accept the "hockey stick"? The peer-review process seems to be controlled by AGW alarmists. Many researchers are afraid to challenge the consensus. There is ample reason for skepticism, especially given the lack of cost/benefit analysis being applied to proposed solutions.

1024 gianmarko  Mon, Aug 10, 2009 12:31:34pm

only if it can also demonstrated that CO2 increase caused the past temp increases. which it cant.
even if it temps start going up again (havent increased in almost a decade) and this can be demonstrated beyond any doubt (current measurements are still flawed) a certain, scientific link to atmospheric CO2 must be demonstrated.

The EPA draft refers to the work being done which offers a new theory of warming that challenges the AGW premise that CO2 is the cause because all other explanation have been ruled out: Svensmark's work on cloud formation. The draft pre-dated publication of Svensmark's most recent work: Henrik Svensmark, Torsten Bondo, and Jacob Svensmark, "Cosmic ray decreases affect atmospheric aerosols and clouds," Geophysical Research Letters, doi:10.1029/2009GL038429, Vol. 36, L15101, 2009.
AGW play book response to explanations involving the sun, is to point to studies which show the variation in TSI is not sufficient to explain the warming. Svensmark's work is not dismissed by this.

Has anyone here read Bjorn Lomborg's writings - he makes a strong argument that it is far more effective (from a cost/benefit, human cost perspective) to address the effects of GW, rather than try to prevent GW by limiting greenhouse gases. You could even make the case that it is the "moral" way to address the problem.

I believe that BL has stated that GW is real. However, I have the feeling that he sees arguing the science as much less important than making sure that we don't adopt the wrong policies.

You won't believe this, but you had my ear until I got to the part where it said (I paraphrase) "But we have these computer models for climate, and when we plugged it into them it didn't spit out the right answer".

Um, as a technical guy who has done plenty of computer modelling, I would be open to the possibility that there was something inadequate in the models. You don't just assume these models are perfect, and use that "fact" as irrefutable evidence that the looked-for effect does not exist. Especially when those models don't give an answer that matches the real world, anyway, and those models were drawn up looking for a specific (different) cause. WTF?

Just the fact that we are talking about "models" (plural) tells you that none among them is considered to be correct. But they have the gaul to presume that at least one (but we don't know which?) is? Or that the trend is? Or that the average is? (Is this some famous principle that "35 wrongs, when averaged, make a right"?)

re: #1002 zombie


Carnage and Culture was not actually written to debunk GG&S; it just happened to present an alternative theory about Western dominance. Hanson was not thinking "I want to debunk GG&S!" as his motivation for writing the book. It was simply his elaboration on an earlier book about military history. It just so happened that his thesis challenged one of the many theses in GG&S.

If what you were saying at first was true, Victor Davis Hansen wouldn't get published by such as Random House in the first place, whether his book explicitly addressed itself to GG&S or not.

And I have the feeling that if Hanson had barged into the Doubleday office and said "I want to debunk GG&S with my new military history book! I hate liberals! Publish it!" they would have most likely not published it.

I don't actually recall seeing many books by major or well known authors that are published that have the explicitly stated sole purpose of doing a take down of another book. I'd guess it's more a job for those who don't mind eeking out a living at the ankle biting end of the book writing spectrum, (people who write titles like 'The Dawkins Delusion" and "Christopher Hitchens is Not Great" spring to mind); I think it's more reasonable to assume readers generally want to see a writer of substance produce his own thesis rather than write a book length hatchet job of someone elses. But I see no evidence for a liberal censorship filter in operation at the publishers.

Now, obviously, it's not like there is a blacklist against all conservative thought at all major publishers. Perhaps I over-enthusiasticlaly stated my case.

You can say that again.

If you are not a celebrity and not an established academic star or well-known pundit, and you approach a major NY publisher with a book overtly and aggressively "conservative" or "right-wing" in thesis -- your chances of getting published are very slim. You'd have to go to smaller publishers that specialize in conservative titles.

I disagree with that too. It's hard for any little known author to get a deal with a major publisher, no matter what the bias of their work may be. If however, the author demonstrates talent and promise(of selling books) then he may be in luck. One example off the top of my head - have you ever read "The Lucifer Principle" by Howard Bloom? He was came from obscure music industry beginnings and was published by Grove/Atlantic,(who also publish Pinter and Beckett) despite the at times extremely 'politically incorrect' observations and analysis in his work. It's certainly not a book that would have got through any 'liberal censorship filter', had such a thing been in place.

And btw, just out of interest, what are the chances for a liberal writer of getting his work published at one of those conservative publishers?/

I disagree Coracle with your runaway greenhouse effect on Venus. Given the same pressure it would be just as hot or hotter here on Earth.

So, Coracle you say at this level (380 ppm) CO2 is a pollutant. What level do you want so it is not a pollutant and still life sustaining?

You know very well that a lot of scientists claim exactly the opposite.

And even if solar activity is not a predictor - neither is CO2 levels. CO2 levels FOLLOW temperature changes - I believe even you concede that ?

That is - CO2 levels have not been the PRIMARY driver. They LAG changes in temperature. If you have any evidence whatsoever to suggest that CO2 levels have been the primary driver of temperature change, I have not seen it anywhere in this long long thread.

Yet ALL the policy prescriptions are linked with suppressing economies' output of CO2. Also - these prescriptions are put forward, drafted into legislation or into international conference conclusions without politicians being honest enough to spell out the dire economic consequences.

If the practical effects of the so-called remedies are deliberately hidden - no wonder people think this is one huge scam.

That is another reason why a lot of us are sceptical if the whole AGW case. There is too much hubris about its proponents.

but wait, the guy keeps talking and starts claiming that if i dont immediatly stop drinking, my liver will surely fail in exactly 30 days, and shows me a computer model that proves that.
not only, i must immediately get out of the bar and run 5 miles in order to rid my organism of the poison. i should also give him the keys of my car cuz i might be drunk, and donate him my house so he can finance his battle against alcohol abuse.
when i express my doubts about the inevitable liver failure he starts getting loud and abusive and calls me an ignorant, a denier, and that i am the ruin of the whole human race, beer is bad and i must do something about it, it is even already too late and i must ACT NOW.

I've read every message on this thread and the links in the "How to answer . . ." and the links from the links and on the key issue, the AGW camp is struggling.

How big (and what sign) is the feedback? Without big positive feedback (from H2O), CO2 isn't scary. The RealClimate link from "Why don't they ever mention water vapor" gives a primer on how the feedback works but doesn't defend the high positive number that is the heart of the catastrophic predictions. For example (from RealClimate):

"To first approximation, the water vapour adjusts to maintain constant relative humidity. It’s important to point out that this is a result of the models, not a built-in assumption. Since approximately constant relative humidity implies an increase in specific humidity for an increase in air temperatures, the total amount of water vapour will increase adding to the greenhouse trapping of long-wave radiation."

"To be sure there are still some lingering uncertainties. Some recent data indicates that tropical upper tropopsheric water vapour does not quite keep up with constant relative humidity (Minschwaner and Dessler, 2004) (though they still found that the feedback was positive)."

Give them credit for being civil and scholarly but the skeptics have arguments that go to the feedback constant that's so critical to the whole thing.

Let's argue that.

re: #1016 kochsr

In the history of science, "the vast majority in the field" have been wrong many, many times. This is really just an appeal to authority. There are thousands of scientists, engineers, meteorologists in the field and related fields that remain skeptical. Also many people in the field are invested in AGW for many reasons - political, financial, reputation. There is something of an Enviro-Industrial-Political complex at work. In a situation like this, we must be very careful of what we declare "facts", and more skepticism is called for, not less.

I suspect that over the next 10-20 years, it will become more and more obvious where the climate is headed.

re: #1028 Charles

No, it isn't. It would be an appeal to authority if the overwhelming evidence from many independent sources confirming the reality of climate change didn't exist.

But that evidence does exist. The majority of scientists accept it not because they're sheep, or because they're being pressured, but because they've examined the evidence and found that it stands the test of peer review.

The current state of science does in fact favor the AGW theory, those who fail to acknowledge this fact and make ridiculous and baseless anti-science and pseudo-scientific statements to the contrary are greatly weakening the “skeptic” side.

There is also a great deal of distortion and propaganda on both the pro-AGW and “skeptic” side being waged by the Media, NGOs, and Politicians, as well as some very problematic proposed solutions that appear over-expensive and ineffective. I personally suspect that there is a sort of “selection bias” and “funding bias” that could also be problematic on the research level, however this is impossible to prove and on the science level this will be sorted out in time as the data and papers are reviewed and subjected to falsification.

I’ve seen a bunch of people chime in here to scold Charles for not toeing the current “right wing” talking points, those people are displaying ignorance based upon the truth distorting effects of partisan politics. By highlighting the disinformation on the “skeptic” side as with the “suppressed” EPA report, and by shining a light on the baseless arguments being advanced, this blog is helping to raise the “skeptics” game and re-frame the debate in more sensible terms.

re: #1030 MKELLY


I disagree Coracle with your runaway greenhouse effect on Venus. Given the same pressure it would be just as hot or hotter here on Earth.

So, Coracle you say at this level (380 ppm) CO2 is a pollutant. What level do you want so it is not a pollutant and still life sustaining?

Of course, high atmospheric pressure would help drive temperature higher. Go high enough and you put the oceans' water into the atmosphere. Go higher still and you put the carbonaceous rocks' carbon into the atmosphere as well. That's (part of) the runaway effect.

As for CO2 pollutants, I'd (I don't have that text book in front of me any more) but I'd say between 50-100+ ppmv of that 380 is directly attributable to anthropogenic causes.

Yeah, I get it. Anybody who doesn't say what YOU want to hear is a liar.

The argument comes from pgs. 105-109 (sec 3.4) of the following report, which quotes it's own sources:
[Link: www.heartland.org...]
Specifically it quotes data (shows figures) from the U.S. Climate Change Science Program (CCSP). Everyone is free to read their argument, look at the data, and decide for themselves whether it seems compelling or not. The overall magnitude of the real data is half that of the model, and there's a cold spot in the tropics that the model doesn't have. The real data shoes barely any increase at all with altitude, whereas the models call for a large, well-defined peak around 12km.

Your turn. Satellite data, and even Hansen GISS-ed up data, show a level trend in recent years, plus noise. Who says we're "still warming", and why should anybody beleive them? This link:
Image: N_timeseries.png shows an Artic sea ice level that exceeds 2007 (which was something of an anamaly). Photos show subs in open water at the North Pole decades ago. So why should anybody think even the North Pole was outside the natural range of variation? Who says the South Polar Ice Cap is "melting"?

Actually you will make a fine object lesson since Sal isn't here to deconstruct.

Do you see that the sun's output has not changed and therefore it can not be irradiance causing the warming? This is really basic logic.

Why don't you see this?

You replied with some specious nonsense about solar wind... Let's apply the rules of a scientific debate shall we?

You are claiming that solar variation is the ultimate driver of observed warming trends.

1. Cite credible data.

2. Make cogent arguments based on sound scientific or mathematical reasoning. Provide mechanisms and plausible explanations for your analysis as supported by the data.

I have countered that the energy output of the sun has not changed on average and therefore can not be driving the warming.

You are now claiming that this has something to do with solar wind...

OK,

Please define solar wind. (It's a flux of particles given off by the sun, but I am certain you didn't know that - What kind of particles? How much energy do they transfer to the Earth etc...) How does the solar wind interact with the Earth to cause warming? Does the Earth receive enough energy from variations is solar wind account for the observed warming?

At the convention, Giaever stated he is skeptical of the importance of the issue of global warming. Giaever also stated that he is unsure if the global committment to implement more energy efficient technology is a possibility. He cited the lack of action and change since the Kyoto agreement: "I don't see much change in these years when we were supposed to have done something about this already. If we were really serious about this thing why don't we talk about nuclear power?"

You say outright that CO2 is the primary driver of climate change.

All I have read suggests that changes in CO2 levels FOLLOW changes in temperature - over very very long periods of data. I simply cannot see how CO2 can be the primary driver - the CAUSE -if it FOLLOWS. In my little world, causes precede effects.

Can you point to any significant period in, say, the last 100,000 years or more where CO2 changes PRECEDED temperature changes and can therefore be shown to be the primary driver ?

Or are you just talking about some extremely recent years ?

Because if you are ONLY citing some recent years - there is no doubt at all that many people distrust that data, for a variety of reasons - as you well know.

I'll need to dig up the sources on this, but from memory, in the geologic record, the CO2 level and temperature level feed back on each other. Warming can lead to more CO2 which reinforces the warming. In previous geologic eras, the start of warming may or may not have been CO2 - I don't know what the time and measurement error bars are, but it is possible that a small CO2 rise (clearly not anthropogenic) could have initiated ancient temperature rises also. It could also have been other forcing factors.

But today, we have a human forcing factor pumping known greenhouse gases into the air with known effects.

re: #1061 MacGregor

Good afternoon Ludwig!
I understand CO2 and temperature peak right before glaciations. Is that true and how does that fit into the argument?

Good afternoon!

It depends on what is causing the glaciation. For instance, there are well known variations in the Earths orbit and rotation that cause some periods to be hotter than others in certain regions. In the past, this was one of the primary drivers climate shifts. Volcanism adding extra CO2 to the atmosphere was another.

It turns out that the in certain regions part of the last phrase is key.

It also turns out that you have to be very careful about the time frames you are referring to.

So my answer is a qualified yes, it has happened that in some cases temperatures and concentrations have peaked before a glaciation... However, that is not always the case and it is not the complete record, and drawing a simple conclusion from it may very well mislead you.

For instance there were periods when a rise in volcanic CO2 thawed a frozen Earth.

[Link: www.aip.org...]

Such great disturbances — even a totally glaciated "snowball Earth" — were not a fantasy of oversimplified models. Geologists turned up evidence that more than half a billion years ago the oceans had actually frozen over, if not entirely than mostly. That seemed impossible, for how could the Earth have escaped the trap and warmed up again? There was at least one obvious way (but it was only obvious once someone thought of it, which took decades). Over many thousands of years, volcanoes would have continued to inject CO2 into the atmosphere. There the gas would have accumulated, since it could not get into the frozen seas. Eventually a colossal greenhouse effect might have melted the ice.(52*) All this was speculative, and proved little about recent climates. But it added to the gathering conviction that CO2 was the very keystone of the planet's climate system — a system by no means as cozily stable as it appeared.

An actual discussion of this is very long. I think you will find anything that you might question, answered in this link.

re: #1068 Optimizer

Please confess to us that you are not really a scientist, 'cause the way I heard it the burden of proof was on the guy with the extraordinary theory.

Well I really am a scientist and you second assertion is correct.

The extraordinary claim is that there is no AGW. You are the one with the greater burden of proof. BUt honestly, that shouldn't matter. For instance I have no "burden of proof" as an underdog theory about the Earth orbiting the Sun. If someone asked me how I know this, I would happily follow rules one and two and give a cogent explanation of Kepler's laws and how to derive them from Newton and then wrap up with the observed data - things like space probes that have actually seen it that way.

Now if your "science" were so good, you could argue this like a scientist.

Let's try again.

I asked you:

You are claiming that solar variation is the ultimate driver of observed warming trends.

1. Cite credible data.

2. Make cogent arguments based on sound scientific or mathematical reasoning. Provide mechanisms and plausible explanations for your analysis as supported by the data.

I have countered that the energy output of the sun has not changed on average and therefore can not be driving the warming.

You are now claiming that this has something to do with solar wind...

OK,

Please define solar wind. (It's a flux of particles given off by the sun, but I am certain you didn't know that - What kind of particles? How much energy do they transfer to the Earth etc...) How does the solar wind interact with the Earth to cause warming? Does the Earth receive enough energy from variations is solar wind account for the observed warming?

Back this up and argue like a scientist. Otherwise, you are just another blow hard who doesn't know anything about the topic.

OK, no amount of whining about how you feel insulted will save you. Answer the questions like a scientist. If you are correct, you should have ready answers to this.

re: #1067 JohninLondon

LVQ

You say outright that CO2 is the primary driver of climate change.

All I have read suggests that changes in CO2 levels FOLLOW changes in temperature - over very very long periods of data. I simply cannot see how CO2 can be the primary driver - the CAUSE -if it FOLLOWS. In my little world, causes precede effects.

Can you point to any significant period in, say, the last 100,000 years or more where CO2 changes PRECEDED temperature changes and can therefore be shown to be the primary driver ?

Or are you just talking about some extremely recent years ?

Because if you are ONLY citing some recent years - there is no doubt at all that many people distrust that data, for a variety of reasons - as you well know.

Yes, in the present case we find ourselves in now, in the early 21st century, CO2 is the primary driver. In other periods, there were many other factors. You have to be careful of making a false comparison, because in those other periods, there was not human produced massive industrialization and pollution to take into account.

The thing that is utterly false is to assume that the most important difference, i.e. the presence of man, has had no effect from the get go.

Blah... Blah... Blah...

If I were to claim that the speed of light is constant in all reference frames, and no one had ever heard of relativity before, I would be required to:

1. Cite credible data that demonstrates the claim

The Michelson Morely experiment would be a great example

[Link: hyperphysics.phy-astr.gsu.edu...]

2. Make cogent arguments based on sound scientific or mathematical reasoning. Provide mechanisms and plausible explanations for your analysis as supported by the data.

One way I might do this would be by applying a Lorentz transform onto Maxwell's Equations and thus derive special relativity.

Now, That is how it is done.

If you can not argue any of your scientific claims in such a manner, you are not talking science. Those are the rules. The only reason you hate them so much and respond in such a childish manner is because you can not substantiate you claims.

Now, do you want to talk science, or do you want to rant about how I am imposing the evil scientific method on you and that offends you?

re: #1029 Jimmah

I don't actually recall seeing many books by major or well known authors that are published that have the explicitly stated sole purpose of doing a take down of another book. I'd guess it's more a job for those who don't mind eeking out a living at the ankle biting end of the book writing spectrum, (people who write titles like 'The Dawkins Delusion" and "Christopher Hitchens is Not Great" spring to mind); I think it's more reasonable to assume readers generally want to see a writer of substance produce his own thesis rather than write a book length hatchet job of someone elses.

That is exactly the point I've been trying to make: it would be a futile pursuit with very little financial or status payoff to "eke out a living at the ankle biting end of the book writing spectrum" by devoting my energies to a book that few people want to read and fewer want to publish. The suggestion was floated that I do so for the sole altruistic purpose of "raising the level of discourse." Well, that's all very well and good and nice and noble, but if someone wants the level of discourse to be raised, then go ahead and rasie it. Don't order others to do so. "Sorry, Billy, mommy/daddy has to devote the next four years of your childhood to a futile pursuit because a commenter on a blog said it would be a good idea for me to raise the level of discourse.

i did. i do all the time. you know, you could easily convince me that AGW is real if you had proper, scientific evidence. but you dont, nobody does. it is a theory, and starting any discussion with stuff like "there is no other explanation" makes you lose any authority and credibility you might have.
also, the fact that you think to be the only one entitled to decide whether an argument is cogent or not makes your credibility to hit rock bottom

anyway, i have already expressed my thoughts on the subject. all this is just academic, good just for killing some time on a blog. you might be wrong, or you might be right, but if you are really a scientist and you really believe AGW will roast us, focus on something useful, which would be for example to find me affordable, abudant clean energy. forget about prius-es, electronic bulbs, cap-and-trade, windmills and photovoltaic, and all that crap (and if you really are a scientist, you know thats crap) and get me ENERGY.
believe it or not, my problem is not avoiding to roast, but avoiding to freeze to death during the harsh, cold winters we get over here.
and think about it, is a win-win situation. get me cheap energy and if you were right about AGW, you might have saved the planet, and if you were wrong, you would still be a national hero for getting us all cheap energy and for sending the sheiks bankrupt.

Just to make sure we understand, sunspot activity actually increases solar output in flux. More sunspots directly equates to higher solar irradiance.

Here is a link:[Link: www.physorg.com...]

[If I did the pasting thingy wrong, sorry. I suck at this stuff and VCRs. Funny for someone responsible for designing a ton of the chemical processing systems used, you'd think I knew how to do this crap.]

Also, the magnetosphere of the sun relaxes and is not as tortuous. This has an effect on our magnetosphere as well. There has been a lot of interest lately in understanding how the magnetosphere/solar flux/cosmic rays affect the atmospheric climate dynamo of this planet.

I am still pretty confident that it will not be due to the effect of some increase of CO2. H2O and CH4 have more adverse effects on heat radiation.

I am still sticking to my theory, er I mean hypothesis, um...my scientific wild ass guess (SWAG) that it will be much colder than last year. Why? I am betting that the sunspot case is real. By the way it was also reported by Hershel. He discovered Uranus and studied the sun as well.

I hold this value as I am not convinced that trace gases cause this cycle. I guess I would be one of the scientists back in the turn of the 20th century who did not believe in aether, Drude theory of metals, ultraviolet catastrophe, etc. I would have continued to search and search and search. We physicists do not like these "consensuses", we like derived equations, tested theories, data plots showing relations, etc.

I guess if you want to follow something based on a "belief" that is fine. I am not a religious person, but I do not dump on those who are passionate about their beliefs. I just like reality. Physics provides that. So if you are a follower of AGW and truly enjoy AlGore flavored kool aid, good for you.

I give this religion about another 3-5 years, then it will be just as interesting as Betamax, the pet rock, and yahoo seriously.

Global warming is actually very much like a religion - it has all the same basic characteristics:

1. It's intangible, in that it's big enough to defy "personal" proof - nobody can be everywhere at once, so if you don't see global warming where you are at, it's obviously going on somewhere else. Just because you haven't seen a miracle doesn't mean they don't exist if you believe they do.

2. It's a natural force outside anyone's control, except for those who ordain themselves as the clergy - who have a "direct line" of influence to the process which the lay person lacks. By setting themselves up as the intermediaries who can exert "control" over the process (carbon credits!) a select group has the ability to exert influence over everyone else.

3. Mankind hates to be at the mercy of events, and takes active measures to avoid acknowledging the fact that we are. Early man created the gods to explain the mysteries of why the world acted as it did - weather, crop growth, birth and death, etc. Plus, some folks figured out it was a great way to exert societal control over the masses. Do/Don't do this not because *I* command it, do it because *god* did. Oh, and don't try and fake it, he's omniscent.

4. Both religion and global warming require adherence to dogma. You don't dare question either, or you will be considered and treated like a heretic. Those in charge know what's best for you and everyone else, and you'll suffer if you don't agree. Pointing out "inconvienent facts" like: it's 65 degrees in IL in the middle of summer and the sun isn't as active as it was during the last solar cycles and other such flagrant (yet provable) facts will get you in trouble. The "facts" don't matter, belief is what does.

re: #1048 ludwigvanquixote

Yes CO2 is the primary driver. This has been demonstrated quite thoroughly.

FTA:

Objection:

Climate scientists never talk about water vapor, which is the strongest greenhouse gas, because it undermines their CO2 theory.

Answer:

There is no climate model or climate textbook that does not discuss the role water vapor plays in the Greenhouse Effect. It is the strongest Greenhouse gas, contributing 36% - 66% to the overall effect for vapor alone, 66% to 85% when you include clouds.

---

It's all about the feedback. H2O follows temperature. The ice cores also show that CO2 follows temperature. But now we're pumping CO2 into the atmosphere independently. How will everything respond?

The real scientific debate is over the functional relationship underlying the feedback. Get into that and you'll get away from the BS on both sides (mostly). This is where the skeptics start to do well. The "tipping point" argument holds no water (pun intended) as we know CO2 was much higher when the dinosaurs were around. But without a tipping point style runaway feedback, extrapolating the current warming doesn't produce much to get alarmed about.

LGV

I asked you point blank to direct me to periods before the last few years when CO2 can be claimed to be the primary driver of temperature change.

You have failed to do so - you argue that we should look only at the immediately-preceding years - the last few years.

Therefore - in all other periods, there have been one or more other primary drivers of temperature change. I fail to see why such earlier primary drivers, or a single primary driver - should not also be the primary drivers for the period you try to restrict us to - a period where many scientists say that the base data is highly suspect.

I put the accent on PRIMARY. Yes, CO2 may help amplify temperature change once it has started - but my question to you remains - how can you use one recent set of a mere handful of years, a tiny spec in the eons of time, to suggest that the rules have changed, that CO2 has usurped the role of primary driver. You are the one arguing the illogical case - the burden of proof is on you. I haven't seen a glommer of any such proof from you, sorry. Just a lot of bluster.

re: #1093 JDubya

just to make sure we understand, sunspot activity actually increases solar output in flux. More sunspots directly equates to higher solar irradiance.

Does it increase irradiance enough on average to account for the observed warming we see on Earth. The answer is no. Energy is conserved. For your overall hypothesis to be correct, then the absorption of the atmosphere would have not changed, while the sunspots have, sufficiently to cause the warming. This is not a true statement.

The atmosphere has had a dramatic increase in CO2 concentration, while the net amount of energy from solar variations is not be enough in of itself to account for the observed changes in temperature.

[Link: www.aip.org...]

Some experts continued to believe that the Maunder Minimum of solar activity must have had something to do with the medieval cold spells. And some persevered in arguing that slight solar changes (which they thought they detected in the satellite record) had driven the extraordinary warming since the 1970s. A few groups pursued the study of possible mechanisms, for example devising experiments that they hoped would show an effect of cosmic rays on clouds. Yet even if somebody did finally manage to show how changes on the Sun could influence climate, the influence could not be very great. Greenhouse warming was bound to swamp any solar effects as the quantities of the gases in the atmosphere soared ever higher. Willson, the leader of the satellite experts, explained that in the future,"solar forcing could be significant, but not dominant."

False. That is why we measure different things in different places. Those records become our eyes and ears in places we cannot be every moment.

But without a tipping point style runaway feedback, extrapolating the current warming doesn't produce much to get alarmed about.

I don't debate that water vapor feedbacks are important. The issue with carbon and why is is seen as such a big deal is that it stays in the atmosphere for centuries - adding heat to the system for as long as it is up there, where as water has the habit of precipitating out of the atmosphere.

Now for the rules again: You claim:

The "tipping point" argument holds no water (pun intended) as we know CO2 was much higher when the dinosaurs were around.

Well, we had no caps then either and much of what is now America - even taking plate tectonics into account was under water.

So, please support your claim that there is no tipping point.

1. Cite credible data.

The fact that much of the Earth we know and love was under water when the dinosaurs were around - even in geologically stable places, would seem to make one think that perhaps a tipping point was reached and that the caps did actually disappear. How do you refute this?

2. Make cogent arguments based on sound scientific or mathematical reasoning. Provide mechanisms and plausible explanations for your analysis as supported by the data.

How will reduced albedo not reach a point where refreezing is made impossible?

IN this case, question 2. is the more important one.

re: #1088 zombie

That is exactly the point I've been trying to make: it would be a futile pursuit with very little financial or status payoff to "eke out a living at the ankle biting end of the book writing spectrum" by devoting my energies to a book that few people want to read and fewer want to publish. The suggestion was floated that I do so for the sole altruistic purpose of "raising the level of discourse." Well, that's all very well and good and nice and noble, but if someone wants the level of discourse to be raised, then go ahead and rasie it. Don't order others to do so. "Sorry, Billy, mommy/daddy has to devote the next four years of your childhood to a futile pursuit because a commenter on a blog said it would be a good idea for me to raise the level of discourse. Sorry about your life."

Ref: bolded statement.

It has not.

Let's be precise, shall we?

Way back at 741, I replied to you:

zombie, I suppose I would like to read that book, if it were ever to come about either by your authorship or someone else's.

Then in 753, in reply to harpsicon:

_Has_ such a refutation/rebuttal book been written in the last 12 years? That should have been plenty of time.

Then in 764:

I'm serious. I _want_ to see a well researched, point by point rebuttal of GG&S. Give me the facts and let me make up m mind, because the facts I see so far don't _look_ cherry picked to me. I'm new, so I don't know if you or zombie could indeed successfully rebut the book. But if GG&S is to be held up as an example of biased ends-dictate-means, agenda-addled research, then someone who held that opinion should have taken it down over the last decade.

Please note here, that I have not suggested or requested that zombie write such a book, just that such a book would be worthwhile to the opinions espoused. I even recognized zombie's "I don't have time" claim at 773

In 831 you insinuate that I have asked you to write this book that I'd like to read, when in fact it would have been more than adequate to have seen it written by anyone and cited by you. And in 938 I reply to your paragraph about writing the book yourself taking your tenses and point of view to continue the conversation.

And last when you claim in 982 that I 'insist [you] devote [your] life to debunking it.' I reply in 985:

I actually couldn't care too much about defending GG&S, since up to this point all I had by way of attack was "I could prove it wrong but won't". as to devoting your life to debunking it, I insisted on no such thing and would thank you not to put words in my mouth. I did ask that you to substantiate your claims, and I explained why...

I do not care to be misrepresented.

I am beginning to doubt your background. But I guess there is a need for an army of believers. I think for every disbeliever created from people investigating the reality of this nonsense, ten more recruits are desparately needed to offset the obvious: people are slowly coming to understand what they did not once question, but followed because these people shrilling about AGW were "experts". No wonder you fiends peddle your nonsense to children, they are about as free of logic and gullible.

Your quote from AIP is nice, but this is not science. This was an essay.

I could get someone to "quote" something just as well. Please provide actual data references not some half-baked scheme written in the best interests of someone else.

Here is a direct study of solar irradiance versus temperature: [Link: www.cfa.harvard.edu...]
And another: [Link: www.igidl.ul.pt...]

Both of these show that you are wrong.

By the way, how are you setting up your problem and stating that energy is conserved? With respect to the planet as a whole? Are you just pulling a "first law only" concept to this argument? A whole bunch of the others are too, that is why they are wrong.

Read the papers above. I think you will be pleasantly surprised to find out that CO2 and temperature changes are not related.

Read and learn. I will probably not be responding after this as it is pretty much the same diatribe:

"It is big oil"
"It is big coal"
"The science is settled"
"meat is murder"
"pinwheels for all"
"not in my backyard"
"it's made of peeepole"

I am leaving my business, to go home, and dangle my feet into my 74F pool. It is now too cold for me to swim, but not the kids. And it is August. In Phoenix. Last year, we were in the pool until October. But of course it is probably Bush's fault, right? Or maybe since we were only into about 180 days of no sunspot activity. Oh, I forgot, your "essay" had some chimp stating again that the fiery ball in the sky has nothing to do with climate: Ignore that hot thingy in the sky! It is this 1 in 10,000 increase in CO2 and not that yellow light bulb up there!""

re: #1114 JDubya

While I have become frustrated with certain fools here, you might notice that I have been sticking to the science of the matters, so let's ignore your left wing chant accusations, and talk real science.

First off The AIP Essay is from the American Institute of Physics and it cites many of the seminal papers on the problem.

Second off, I am having difficulty loading your links, so I can not read and learn from them, but, if they honestly are claiming that the sun is the primary driver, they are wrong. That claim has been debunked.

Willson reported a brightening of 0.04 percent between the two most recent solar cycles, Willson (1997); this was controversial, see Kerr (1997); similarly and more recently, Willson and Mordvinov (2003); discussed by Byrne (2003). Experiments: e.g., Svensmark et al. (2007) (which brought a strong press reaction but proved little). "Mere 'blip':" Nelson (1997)

.

Do go back to the page and read and learn from any of those papers. This is observed data.

Now as to your wonderful claim,

Ignore that hot thingy in the sky! It is this 1 in 10,000 increase in CO2 and not that yellow light bulb up there!""

For that to be true, the amount of energy received from the variations you are claiming are the primary cause, would have to account for the amount of rise in temperature. When I said that energy is conserved, it was not a specious argument, rather, it was the core of the argument.

It takes a certain amount of energy to heat the planet as much as we have observed. This is a true statement. When you look at the amount of energy coming from solar variations, it is not sufficient to cause as much heating as we have seen. Since energy is conserved, the primary source of heating must be coming from something other than the solar variations.

Now for you to counter this, you need to show me that the energy budgets add up the way you say they do. You do not.

re: #1105 LudwigVanQuixote

Well, we had no caps then either and much of what is now America - even taking plate tectonics into account was under water.

So, please support your claim that there is no tipping point.

1. Cite credible data.

The fact that much of the Earth we know and love was under water when the dinosaurs were around - even in geologically stable places, would seem to make one think that perhaps a tipping point was reached and that the caps did actually disappear. How do you refute this?

2. Make cogent arguments based on sound scientific or mathematical reasoning. Provide mechanisms and plausible explanations for your analysis as supported by the data.

How will reduced albedo not reach a point where refreezing is made impossible?

In this case, question 2 is the more important one.

Good questions.

1) Since plate tectonics have moved everything around -- particularly Antarctica -- the state of the poles is significantly affected by other factors (specifically that the South Pole wasn't land).

More importantly, the term "tipping point" refers to a runaway effect that sends things off to a limit. The Mesozoic period may have been hotter, but not runaway hotter.

We all agree that raising CO2 by a factor of 5 would lead to a warmer planet. And a warmer planet would raise sea levels. However a few degrees isn't going to melt Antarctica and might (due to increased precipitation) actually increase the ice. The NSIDC shows the Antarctic Sea Ice extent growing over the last few decades, even as global temperature has increased (select "Antarctic, monthly" on the right hand side to see the trend):

[Link: nsidc.org...]

The open ocean has a different sensitivity than land. This may apply to northern Greenland too. Seems I've already moved on to question 2.

2) Is the onus probandi on me to prove there's not a tipping point? Absent a good argument for a tipping point, the warming should track the log of CO2 -- and that's tracking pretty consistently. I'll take the last 30 years of satellite data for the warming trend and just extrapolate.

It's going to get warmer; China has just about guaranteed that. There will be consequences -- some good, some bad. The agricultural output of Canada and Russia is going to go up. The oceans will rise (and I live in the SC lowcountry so this matters to me). I figure in 50 years, they'll have risen 100 mm or so. It's AGW but not CAGW.

Again, you are merely quoting an article. The two journals above are actual studies and have shown your ideology and beliefs are wrong. Both of these are studies of 100 years+ of data. If you are going to debunk, please show some other analysis other than, yet again, an article in AIP. I would caution using AIP site articles as a number of physicist are a little edgy that this group is taking a stance. Same as ACS. Scientists do not like being catorized as in the tank.

The conservation of energy statement of law one of thermodynamics is nice. It considers the economics of the system. The budget means nothing without considering the second law: entropy increases, always.

To state that the incoming flux of ~2 x 10^17 W/Earth total area, an amount that is 10^5 times the amount of energy man consumes per second and think that the heat effects of our produced energy versus the heat effects of the suns refraction/absorption/reflection/consumption/etc is more is quite simply ludicrous.

re: #1123 Pythagoras

The tipping point I am referring to is a point whereby we have lost enough of the caps and the oceans and atmosphere is warmer enough, that no amount of reduction in future emissions of carbon will prevent the eventual total loss of the caps.

The reasons why such a point exists are:

1. Carbon hangs out in the atmosphere for centuries.

2. While it is up there, you will have an increased greenhouse effect and you will have more heat trapped because the sun never turns off.

3. As you melt ice, (caused by the original higher concentration of CO2, which made the atmosphere and the oceans warmer) it reflects less light back out into space. The light instead is absorbed by water and then the atmosphere making both even more warm, because the sun does not turn off.

4. This melts even more ice at a faster rate.

5. Step 3 and step 4 become a repeating cycle. The salient question is, is there a point a which the increased rates of melt will be assured to overtake any of the cooling forcing from seasonal changes and negative feedbacks. The answer is yes. Such a point does exist. The point at which initial carbon concentrations are high enough to assure that that cycle will perpetuate itself until the caps go is the tipping point.

There is great debate as to when we hit that point. However, such a point much exist.

re: #1126 Coracle

If we start with 300/1,000,000 (300 ppm) and go to 380/1,000,000 (380), I like round numbers as numbers really mean little without understanding the physics behind the function. So I said 400/1,000,000

Well, 300/1,000,000 is really 3/10,000, right?
And, 400/1,000,000 is the same as 4/10,000, right?

And if the atmosphere goes from 300 to 400 ppm, really it just added 100 more part3 to the mix, right? So it changed by 1 molecule for every 10,000.

Then look at the actual papers cited in the article. These are some of the seminal papers to be read. The journal references are there.

You will probably be upset that this is the position of the APS as well as NASA and NOAA.

Now, how can you call yourself a physicist and ignore a conservation of energy argument?

Either there is enough energy from your variations to cause the heating we have seen , or there isn't. It turns out that there isn't. This is very simple. Since energy is conserved, it could not have just been created ex nihilo. It had to come from somewhere. The place it came from is that more of the sun's energy is being trapped, rather than the sun shined more.

I simply do not even begin to see how you entropy argument makes sense. Could you please expand it a little? What does that have to do with how much solar energy man consumes? Do you mean when we eat plants? What are you saying?

Your argument about the second Law is a bit specious. I have actually no idea how to even address it, because it just makes no sense as is. Please clarify your thoughts.

The rest of this is an utter joke. Heat radiates at 4pi steradians. Whatever the molecule radiates back to earth, half radiates to space. Radiative forcing is still a theory. Everyone of the climate scientists has their own radiative forcing scheme. Everyone. Stating that rising air, that is expanding, is somehow radiate more heat back is a clear violation of the second law of thermodynamics: expansion is not reversible. The rising, expanding gas does not release heat radiation back, it cools down. To say otherwise would have to segragate that clouds don't count because they have to make rain fall and water our plants and stuff.

the tipping point theory is disproved by geological data. CO2 and temps used to be way higher. that didnt stop glaciacions to occur, and didnt cause runaway warming.

And what data is that? I just told you about the tipping point I was referring to. Geological data certainly supports that there were times when we did not have polar caps. How does this refute what I said?

"is there a point a which the increased rates of melt will be assured to overtake any of the cooling forcing from seasonal changes and negative feedbacks. The answer is yes. Such a point does exist."

says who? computer models?

Well no actually, if you follow the logic of the cycle you could prove analytically that such a point must exist for some critical concentration of CO2. Now mathematically, there is a difference between proving something exists and calculating it. The computer models are an attempt to actually calculate that point.

Yes, but in order for this to happen the ice has to melt in the first place. The Antarctic isn't doing that and it is, by far the largest portion. It is much too cold to melt and the only way it loses ice is by chunks breaking off the edges, which will continue indefinitely as the ice accumulates in the middle and migrates out glacially. Meanwhile, if the atmosphere gets warmer and holds more H2O, that's just more for the Antarctic to capture. That seems to be what's happening as the Antarctic continues to slowly increase.

But note: my guess as to the mechanism doesn't matter. What matters is the empirical fact that the Antarctic ice is increasing. We'll lose some albedo up north but the south is holding steady or better. Maybe that's sufficient to produce a tipping point but I need to see the case made. The poles don't get the lion's share of solar radiation anyway.

I can be convinced. Maybe I missed this argument somewhere.

I did mean must and it is very simple to set up a system of equations that would prove this at least to first order. Right? This is a basic related rates deal. This analysis has been done. Why don't you try it?

Again, check out the APS or Princeton GFDL or the MIT research websites to see the analysis?

"1. Carbon hangs out in the atmosphere for centuries."

The rest of this is an utter joke. Heat radiates at 4pi steradians. Whatever the molecule radiates back to earth, half radiates to space.

But what about the absorbed energy through molecular vibration that causes heating in the first place? Is energy no longer conserved here either?

Radiative forcing is still a theory.

Radiative forcing is still a theory.
Radiative forcing is still a theory.

If you make a claim, back it up or shut up.

A modification of your rules:
1. Cite credible data that demonstrates the claim
It is up to the scientists reading the data to argue how it is not credible or how it does not demonstrate the claim.
2. Make cogentarguments based sound scientific or mathematical reasoning. Provide mechanisms and plausible explanations for your analysis as supported by the data [last sentence entirely redundant] Again, it is up to the scientists reading the argument to show faults in the reasoning or how the argument is unsupported by the evidence (which must be supplied as part of the proof in scientific or mathematical reasoning).

Without the qualifiers, your rules may be acceptable. You do not get to be arbiter of what can be deemed scientific in this or any other forum.
I did not complain that you were imposing scientific method upon me, merely that your definition of acceptable "scientific" input seems to be congruent with your own scientific conclusions.

Have you read Svensmark's August paper which I cite to above? Address the content, if you will. I have already seen the riposte at RealClimate and do not find it dispositive.

re: #1050 ludwigvanquixote

Right I caught someone arguing about force, when he obviously from context, had no clue what the concept of force is. If it turns out you don't have the basic understanding needed to make a coherent scientific explanation, then you get shot down.

This is a lie. I mentioned concatenated force multipliers in the case of the butterfly effect, where the flap of a butterfly's wings can cause a slight change in air current, which can cause additional evaporation, which can cause a cloud to develop that can give rise to a tornado or a hurricane. The idea has to do with sensuitive dependence upon initial conditions (SDIC), where tiny causes can result in massive effects.

You responded by maintaining that there were only four fundamental forces in nature: the electroweak and electrostrong nuclear forces, gravitation, and electromagnetism, and sarcastically asking which of those I was referring.

But I was employing the term 'force' in its classical sense, as it is found in Newton's famous equation F = MA (Force equals mass times acceleration), otherwise known as the Second Law of Motion.

Clearly when a butterfly's wings flap and accelerate the mass in the surrounding air molecules, force is being applied. Even a village idiot would know that.

Which must mean you live in the country.

Right. There are certain buzz-words that indicate the person is nothing but an insecure intellectual fraud. Those are some of them.

"Energy" and "entropy" are buzz-words tossed around by all sorts of wankers with intellectual pretensions-- cranks, to be honest-- who write scientists with their elaborate theories of...nothing. Just wankage.

Sal: as I stated before, we are not dealing with a concatenation of force-multiplying intervening factors, but a direct causal relationship.

I can say that because the quotes you've provided are all you have provided. You have provided no additional information that demonstrates he has anything other than blind opinion. In my quick, admittedly non-exhaustive, search on him, I turned up no additional quotes, and confirmation he's published no research on the subject. I cannot read his mind and see whether he has correlated 10,000 facts to come up with his conclusion, or simply "feels" that that's correct, but given everything you have presented that he has said, there is no evidence for the former.

Just because he has the background to thoroughly understand the science does not demonstrate that he has taken the time to do so.

Go away

In the case of temperature transfer from air to ice, Zombie answered your stupid question in meticulous and painstaking detail upthread - molecules move faster when they are hotter, and where there is a differential, they transfer some of that motion to adjecent colder, slower moving molecules, losing some of their own in the equilibrating process:

[Link: littlegreenfootballs.com...]

You even acknowledged as much:

[Link: littlegreenfootballs.com...]

She then pointed out that sunlight played a minor part relative to air temperature at the poles due to the extremely oblique angle at which sunlight strikes them, the low sunlight energy absorption rate of ice and snow due to its high reflectivity coefficient, and the vast amount of atmosphere they must diagonal through, and that seawater played a minor part relative to air temperature as far as the Antarctic and Greenland Ice Caps are concerned, because, unlike the Arctic Ice Cap, they rest on land:

[Link: littlegreenfootballs.com...]

I then proceeded to demonstrate by empirical analogy why a gradual 7 degree C increase in global temperature over the next century would not even remotely approach sufficiency to melt the three ice caps in the next hundred years, given the evidence of the past hundred:

[Link: littlegreenfootballs.com...]

And thusly was your alarmist, extremist, sensationalist and Hollywood dystopianly catastrophist Day After Tomorrow apocalypticist Doomsday complete cap melt and ten meter sea level rise in the next century scenario thoroughly, comprehensively, conclusively, and irrefutably debunked.

You are very welcome my friend. I exist to serve.

I am willing to spend hours talking about this, because the threat is very real - I know it is, not that I believe it it is, and the solutions that people are talking about don't work.

It would be fabulous if the left could press for more scientific solutions.

It would be fabulous if the center stopped believing that a small economic band aid in terms of emissions will help. Cap and Trade, as we have it, will not avert the crisis, and direct resources to places other than things that might work.

It would be even nicer if the right stopped living in denial. It would be fabulous if the right, that half believed, would then get it through their heads that an ecological collapse would also lead to an economic collapse.

While we sit and masturbate over the issues, the threat still looms and the problems still grow - and so far, no one is really doing what needs to be done on a policy level.

I do not care to be misrepresented


I was referring to your comment in #938 above:

"What good it would do to publish or present a cogent, well researched rebuttal? How about raising the level of discourse? How about presenting a strong (should it indeed turn out to be strong) challenge to a prevailing theory? If you are indeed *correct*, how about replacing Diamond as the prevailing theory? "

I took that to mean that to back up my words, I should write the book as described. "How about..." doing this or that seemed to me to be you saying "How about you write the book, hunh?"

I didn't think I was misrepresenting you. Sorry if I misunderstood.

---

This has to be the most trivial and pointless tail-chasing discussion I've had on LGF in many years.

I say GG&S is a piece of crap. If you don't like that statement or disagree with it, then either say I'm wrong and be done with it, or, as I do with 10,000 comments a day I disagree with: ignore it. Why get into a endless imbroglio over a rather insignificant comment about a book I haven't even seen in a decade? How many quadrillions of times have people rendered their opinions about movies, songs, books, games, etc. on the Internet? And 99.99999% of the time such statements simply stand as that person's opinion, and no further comment is necessary?

Was it simply because I said, basically, "Ah, I could debunk that thing, but it's not worth my time."? I mean, isn't that the most common verbal put-down technique in the blogosphere? In my case it happened to be true -- I could put a serious beat-down on GG&S given sufficient time and resources. But even if it wasn't true (as it is not true when 99% of other comments say similar things every day on every topic under the sun) -- what's the big deal? Just write me off as a typical internet blowhard if you think I was spouting off too grandiloquently.

Strangely, the last time this happened to me was when I wrote a negative review of the film "The Constant Gardener" at IMDB, and the other commenters went ballistic. That thread is still going after over a year. I have a suspicion a year from now people will be challenging me to "prove" why I don't like Guns, Germs and Steel.

I see opinions people render every minute of every day that I disagree with. That's what the landscape of the internet is composed of. Let it go, people. If you disagree and love the book -- then scroll on by. And if you remain curious about what some of the flaws in GG&S might be, then read the reader reviews of the book I posted in comment #982 as a starting point.

re: #1200 zombie

I was referring to your comment in #938 above:

"What good it would do to publish or present a cogent, well researched rebuttal? How about raising the level of discourse? How about presenting a strong (should it indeed turn out to be strong) challenge to a prevailing theory? If you are indeed *correct*, how about replacing Diamond as the prevailing theory? "

I took that to mean that to back up my words, I should write the book as described. "How about..." doing this or that seemed to me to be you saying "How about you write the book, hunh?"

I didn't think I was misrepresenting you. Sorry if I misunderstood.

Apology accepted. I see where the misinterpretation came in now.

---

This has to be the most trivial and pointless tail-chasing discussion I've had on LGF in many years.

Your welcome. Clear communication is essential. If I hadn't hunted down this entire trivial trail, you'd likely have dismissed me for being some whacked out nutjob demanding you commit to crazy bookwriting schemes for my sole edification. Now at least you know that that second part isn't true, and I know that you have the gumption to look through the whole pile to see where it went wrong. Win-win.

I say GG&S is a piece of crap. If you don't like that statement or disagree with it, then either say I'm wrong and be done with it, or, as I do with 10,000 comments a day I disagree with: ignore it. Why get into a endless imbroglio over a rather insignificant comment about a book I haven't even seen in a decade?

Why not? Yours was the first serious objection to it I'd seen, and I was intrigued as to the reasoning.

How many quadrillions of times have people rendered their opinions about movies, songs, books, games, etc. on the Internet? And 99.99999% of the time such statements simply stand as that person's opinion, and no further comment is necessary?

Context. At the time the original comments were made, I perceived it as an attempt to establish your authority on the subject, and then infer authority on the actual subject under discussion. But I couldn't let it stand when no proof was offered.

Was it simply because I said, basically, "Ah, I could debunk that thing, but it's not worth my time."?...But even if it wasn't true (... what's the big deal? Just write me off as a typical internet blowhard if you think I was spouting off too grandiloquently.

Well, yes. And the reason I didn't want to write you off is because I've seen that you are respected here, and I didn't want to write you off out of hand. That would likely have been a disservice to both of us.

I have a suspicion a year from now people will be challenging me to "prove" why I don't like Guns, Germs and Steel.

Not from this corner, at least.

I see opinions people render every minute of every day that I disagree with. That's what the landscape of the internet is composed of. Let it go, people. If you disagree and love the book -- then scroll on by. And if you remain curious about what some of the flaws in GG&S might be, then read the reader reviews of the book I posted in comment #982 as a starting point.

This thread system reminds me very much of good ol' usenet. But with many more bells and whistles.

I have checked both your links. One is two years old - predates Svensmark's latest paper of August 2009, and the other quotes from the RealClimate article which does not debunk him and which I had read anyway.
I shall continue to search for a scientific debunking - not an airy gesture of dismissal.

re: #1204 shortshrift

I'm not certain what you don't like. They give you up and up counters to each of his main thrusts. Also, he did his first cosmic ray paper in 1997

Here is the link to his PRL

[Link: prola.aps.org...]

So I don't know how you are getting that either of my links was outdated.

But if you don't like those, then here are some heavier hitters. How about these then:

Testing the proposed causal link between cosmic rays and cloud cover
T Sloan et al 2008 Environ. Res. Lett. 3 024001(6pp)

[Link: www.iop.org...]

Abstract:

A decrease in the globally averaged low level cloud cover, deduced from the ISCCP infrared data, as the cosmic ray intensity decreased during the solar cycle 22 was observed by two groups. The groups went on to hypothesize that the decrease in ionization due to cosmic rays causes the decrease in cloud cover, thereby explaining a large part of the currently observed global warming. We have examined this hypothesis to look for evidence to corroborate it. None has been found and so our conclusions are to doubt it. From the absence of corroborative evidence, we estimate that less than 23%, at the 95% confidence level, of the 11 year cycle change in the globally averaged cloud cover observed in solar cycle 22 is due to the change in the rate of ionization from the solar modulation of cosmic rays.


Slightly more readable from AAAS

[Link: www.sciencemag.org...]

CLIMATE CHANGE:
Study Challenges Cosmic Ray–Climate Link
Richard A. Kerr

If rising levels of greenhouse gases aren't pushing up global temperatures, as contrarians argue, what else could be? The leading alternative has been a fickle sun, and the sun's most likely--or most heavily promoted--agent of change has been cosmic rays. Now scientists have published the first comprehensive modeling of how the sun might indirectly thin cloud cover and thus warm the planet. It suggests that cosmic rays are not up to the task by two orders of magnitude.

Thank you again. Svensmark and others have responded to criticisms over the course of 10 or more years, and other studies have supported his theories. I was looking for a bang-up-to-date critique of his August 2009 paper - just out.

LVG
you are obviously not a scientist.
you reject any debate, and dismiss anything that doesnt conform to your view as bogus. is obvious you have no idea what a scientific method is. or maybe have forgotten it.
moreover, despite the fact that you are obviously playing in the team of the AGW believers, you try to depict yourself as objective and above suspicion, a referee who can decide which line or reasoning is acceptable and which one is not. pathetic. there is not one milligram of objectivity in your statements. that disqualifies you from claiming the status of scientist. you are a partisan.
anyway, i recommend you to read this. i am no big fan of wikipedia, but this paragraph is quite accurate
[Link: en.wikipedia.org...]
expecially focus on the word TESTABLE
AGW theory is currently not testable and wont be for a long time. all valid scientific theories have been subjected to tests and passed them.
AGW theory fails miserably as soon as you move slightly from the supernarrow range of prerequisites on which it is built, and leaves dozens, hundreds of unanswered questions. it is a theory that requires tons of faith to be believed, and which is held together by tons of rhetorics, by a very delicate equilibrium of cherry picked "facts", and by ignoring tons of data which are not consistent with it.

this is no news, all AGW believers i talk to must use industrial doses of verbal contortions to promote their beliefs.

AGW might be real, might be not. as it is now, is just a theory so please stop trying to pass it around as a FACTS. thats forgery, not science.

1209 gianmarko  Tue, Aug 11, 2009 1:31:59am

actually, i dont know why i keep calling AGW a theory. it doesnt even satisfy the basic requirements of a theory, considering it has not been able to produce one single verifiable prediction. on the contrary.

even the whacky pre-galileian theories of planet motion were able to predict the planets position with some precision.

AGW is just a hypothesis.

re: #1208 gianmarko

I'm not a scientist, darn, what an awful surprise... It says physicist on my lunchbox...

I am surprised you think I have rejected your scientific claims, you have yet to make a valid scientific argument for me to even get to calling bogus. You seem mostly to be repeating incorrect talking points when not making political speeches or insulting me.

I think one of the things that many people miss in scientific debates, is that your opinion and for that matter my opinion or anyone's opinion doesn't matter. Opinions mean nothing. Neither do other views, once the evidence has come in. There is no second place in science. There is no "other hand" to be equinanimous with.

In the end we have a very spoiled and narcissistic culture. Everyone is a genius, and everyone has a "right to an opinion" about everything. When confronted with an area where one can be demonstrably wrong, proven wrong and most painfully of all told that they are definitely wrong, it hurts egos that are used to being stroked.

In science, no one is a special snowflake. No one gets kid gloves and no one who is wrong, gets given a pass.

In fact, they are proven wrong.

Many hate this. It makes them feel stupid. Just being wrong does not make one stupid. Scientists get shot down all of the time, only to grow from the experience and be the monkey with the bone next time.

What does make one stupid is when clear explanations are given and that person refuses to process them. What makes one stupid is blind obedience to falsehoods because they are more comfortable.

I will just say it. In the course of this little thread, I have met a lot of stupid.

I have seen people falsely claim knowledge they do not have only to turn into angry children when challenged. I have seen people stick to the same arguments over and over, when if they could just think in terms of basic math or grade school science, they would see the flaw in their arguments. I have seen people repeat the same slogan over again and again as if the slogan were a magic ward against all possible arguments. My favorite one is "What is the ideal temperature for the Earth?" I suppose in the sense that such slogans are mantras against learning or thinking, they are very effective. But they do get tiresome. I have seen people make basic mathematical errors and compare themselves to great scientists independent thinkers while convinced of their own brilliance.

Narcissism all.

Then we get those who simply feel that living in fantasy is more important than reality. They posit relativism in science. This is the worst narcissist of all.

Consider your relativism about arguments. I am not the only arbiter of what is cogent, however, there are certain things which are independent of my opinions. These are things like mathematics and logic. They are neutral and above your, or my, desire to be right.

This is the great strength and reason why science works at all.

And you my dear poster, are convinced that the thing you hate the most is the demand that your arguments be logical, mathematical and based on solid evidence.

I have also seen all manner of projection on this thread. To accept things because they seem right to you subjectively, without the objective support of observation, reason and mathematics, is called faith. And of course, since you see your views as an article of faith, you project that my views are those of another heretical faith - the Al Gore Cool aid faith I believe you called it?

Well, I suppose this was a very academic way to catalogue the different childish ways that morons are bothersome.

i will try to make a clear example of my views, because you keep dragging the argument in the wrong field.

this is not a debate whether the dragon in the garage is male or female.

this is a debate whether there is a dragon. you claim there is one, i claim there is none, position for which no faith or proof is required. the evidence you bring forward to demostrate its existence is vague, circumstancial, biased, "adjusted", you name it. most reasoning is done with a precise target in mind, whichs is the wanted result.
i cannot see the dragon, touch it, smell it, xray it.
you feel a warm air current, and conclude is the breath of the dragon, because it cannot be anything else.

the day clear, consistent, verifiable, testable evidence is there, i will believe to AGW.

you are of course free to believe to AGW, you are not free to pass it around as scientific fact, it simply doesnt satisfy the minimum requirements.

That fraction of 1 degree is possibly equal to or greater then the error that could be made between all those "thermometers". I see people shouting "It Has Never Been This Warm Ever This Fast!

So very true...BUT...I'm still waiting to see REAL evidence. We can postulate until the glaciers are covering most of the US again...the FACT remains that modeling DATA is just that...modeling data. And basing decisions on modeling data, such as the AGW crowd are want to due, is sound science??

I work with modeling software for Radio Frequency coverage prediction analysis...it provides a means (along with USGS topographical data and other variables) for predicting what RADIO coverage might be like in a particular area. There are MANY variables that have to be accounted for and there are MANY different algorithms that are used to simulate different radio frequency behaviors within different environments. These programs provide a GOOD starting point, but even in this relatively simple example the models never get it 100% correct because there are too many unknown variables. Too many unknown variables.

The point being...this is a relatively "simple" comparison to trying to model something as complex as the global climate and all of the forcing variables that go into climatic change. And you (corporate you...not you specifically) want to say that the science is settled...or even that there is definite prove that MAN is causing SIGNIFICANT affects to the global climate???

I do look at BOTH sides of this discussion with my eyes open. I have friends who have been involved with climatology (both terrestrial and space) for over 30 years (a significant portion of time of the collected data that is used in these discussions) and continue to be excoriated by the zealots that AGW is where it is at and that the science is SETTLED.

Again, a very simple question...and look around and past all the modeling discussion and show us the definitive proof that man has caused significant impact to recent climatic change.

Please. I'm sorry for the gratuitous insults (have nothing against star trek, personally--love it!) but please, please, listen to him. A little?

Well, I don't know if anybody's still around, but I'm back and trying to catch up on things.

This one struck me as odd. The "internet klingon" bit was amusing, but I don't get why anybody would "implore" me about anything. I also don't get what, exactly, there was to "listen to". I'm in the technical trades, myself, and all I was hearing was a guy regurgitating some methodology, and demanding that we accept rules of discussion that are specifically designed (by him, not by "science") to silence any debate with him.

Was I supposed to be impressed that he gave somebody a hard time about using the term "force" in a sense that was more in line with the term "forcing function" than it was with "F = ma"? He was nit-picky (and insulting, of course) about that, but was good with someone else using the terms "heat" and "temperature" interchangably.

Or was it some modest discussion that involved "specific heat" and "heat of fusion", that vastly oversimplified things, and which made the ridiculous claim that the Antarctic could melt if it went from -50C to -43C down there?

This is the "scientist" I'm supposed to listen to, in order that I might "see the light", and help Save the World?

You know, this apocalyptic end-of-the-world stuff is all very exciting, and a lot of people are seriously in love with the idea that, in their doing a few modest things in their lives that cost some money, they are virtuously "saving the world", but common sense ought tell you that these things are generally a lot of hype. How long are you guys going to listen to these Chicken Littles before you notice that, hey - the sky's still up there, and ain't going anywhere?

re: #1219 JustAHouseWife

I see from the data C02 concentrations in the atmosphere much higher then today in the past and it still got cold.

Point 1: The climate science that supports AGW does not deny other forcing factors for earth's climate - present or past. It merely concludes that anthropogenic causes are becoming significant-to-dominant in the modern era.

I see from the data C02 concentrations in the atmosphere much lower then today and it still got warm.

See Point 1.

I see in the data that most of the life on this planet loves it when it is warm not when it is cold.

Pont 2: All climate change modifies and/or disrupts ecosystems. Sometimes gradually, sometimes catastrophically. Some systems have the ability to adapt at the necessary pace, others do not. Humans don't adapt to these kinds of change to any meaningful degree on the decadal timescale - we adapt our surroundings to us, creating, at the minimum, local additional variations in climate.

I see from the data 22 ice advances and retreats in the Northern Hemisphere over the last one million years. I see from the data the last big retreat began 20,000 yrs ago. I see from the data we are in a retreat cycle right now.

See Point 1.

I see from the data a tiny blip in that retreat called the Little Ice Age happening a little while ago and ending around the 1850's and the "warming trend" continuing once from there. I see people ignoring all that physical data.

Then you're not checking multiple references in this thread.

I see 1,000s of "thermometer" readings of "the whole world" going back a thousand years and up through "The Industrial Era" made with all sorts of gadgets and proxy by all manner of people; not at all calibrated with each other ; being plugged into a computer model "of the whole world"; and these readings are smoothed and adjusted and regurgitated over and over again to claim an "alarming" fraction of one degree rise in "global average temperature".

Then you are not paying attention to how models are built, constrained, and tested. Read the actual papers. Understand the caveats and the known - and stated - limitations of the different models, and learn what a model conclusion actually says instead of what either pro- or anti- side says it says. The papers are accessible to anyone who wants to read them. You do not need any third party to run intellectual interference for you.

You on the other hand see what you want to see.

That's true and not true.

What I want to see, and do, is honest research producing honest results, verified by the peer review and repeated by multiple parties in challenge.

What I don't want to see, and do, is that the evidence shows we're increasingly karking up our atmosphere, and it's affecting the planet, and us, adversely.

What I don't want to see, and do, is that both sides, but the denial side far more, are unwilling to engage their own neurons and assess the data in an objective manner, letting others - some with very clear un- non- and/or anti- scientific agendas make up their minds for them.

We know there's a difference between "the output of a computer model" and "scientific evidence", and all the tricks that can be pulled to try to "prove" one thing, when the opposite is true.

I was disappointed in our beneficent (NOT sarc) host, however, for calling many "anti-science" for putting stock in one scientific theory, vs. the one that has him convinced. The one guy even professed to be an atheist, and he's being lumped with the Creationist crowd.

In the field of climate science there is way too much obfuscation.

Prominent scientists who refuse to publish the code used in their research; governmental bodies refusing to publish raw station data (instead of the nice graphs which have been passed through phenomenal data grinders) and so on.

That is more than enough to leave a reasonable doubt about the veracity of the AGW hypothesis.

I've been; along with my husband's help ; reading papers for longer then Charles stated he had. I was tired of political indoctrination of my children in school and having them coming home being scared from what Al Gore put out too. Been paying attention more then a few years, more like 5 or 6. I also stated my husband was exposed to these early models and papers in school where he took among other things classes in climatology. And I also stated he found these AGW papers lacking and so did his professors and those things lacking ARE STILL THERE. We pay attention to the raw data more then anything and and the global temps have flat lined in the last 8 yrs despite co2 concentrations "on the rise". I followed the Congressional meetings on Climate Reconstructions. I know what's wrong with the proxies. I've followed the statistical audits and I have seen how the computer code and datas are not being shared freely and I see a very pronounced tight little "climate science" culture grow in the media, academia and on the internet. They especially do not like geologists which is really sad; since without geologists "climate scientists" would have no idea the climate could change at all. I also know that climatology's roots are in statistics and the National Academy of Sciences Statistical scientist at those Congressional Meetings said "The data does not support the conclusions" for the Hockey Stick. He also found these people some people call "The Hockey Team" were reviewing each others work. That's the same data being regurgitated and sited in most of these papers and every paper I look at recently does not include the last few years of the flat line/cooling trend. How convenient. Regarding the sun. Even NASA's "Global Warming Info" page states the we do not know enough about the sun especially in models.

I found "Point 1" to be intentionally obtuse. JustAHouseWife was clearly pointing out that history has shown that CO2 has never been the driving factor, even when it was at higher levels. You fail to explain why anybody should believe that lower CO2 levels should magically become dominant, just because some of it is being caused by industry.

"Point 2" did nothing to dispute the claim that humans have historically done better with somewhat warmer climates. Actually, it really didn't address the point that JustAHouseWife had made at all.

You accuse JustAHouseWife of "not checking multiple references in this thread", but I've read the whole thing and don't remember any discussion of what she brought up. You say she's "not paying attention to how models are built, constrained, and tested" when what she's saying shows that she has a pretty good idea about what is going on. Your "Read the actual papers" is code for, "Either read through a mountain of papers by people who support my view or just shut up and believe what we tell you." Followed by the usual condescension. It's the usual ad hominem: "If you don't buy it, you're not doing your homework - there's something wrong with you - not with our argument". All while not addressing her points at all.

The second law of thermodynamics does not apply to individual molecules, it applies to the net flow of energy in the entire system. How could it be otherwise?

Does everyone agree with the above?

I found this in "How to talk to a Skeptic". This just baffles the devil out of me. I donot think this can possibly be anywhere near valid.

If all the molecules in system donot follow the 2nd law then the system will not follow either.

re: #1229 JustAHouseWife

I apologize if my words offended. I had not gotten the impression from your statements that you had investigated thoroughly. I have stated before that reasonable people can read the same information and disagree on the results. Perhaps you and I, or you and I and your husband could have a fruitful discussion about some of the specific references and models that you see as inherently weak. That might be quite interesting and useful for all of us.

Climate science is not my direct field, but it's not that far away, and I've been learning an reading about it for over 20 years. I recognize how complex the system is. I recognize there are natural forcing factors and cycles. You and I conclude differently about their relative importance in their current effects. One fact in evidence is that at no time that we have insight to has the rate of CO2 changed so rapidly as in the modern era, due to industrial processes. CO2's infrared reflectivity is a known value. More heat is getting trapped in the earth's atmosphere. What happens to that heat is further open to interpretation - does it simply drive weather engines harder? Does it all go into average global temperature increases? These things are, I completely agree, not fully understood. But at the most fundamental, the physics is not that difficult. More heat is trapped in the atmosphere, and it has an effect.

As for the last 8 years, I don't know. My jury is still out on that one. It so hapens that for 4 or 5 of them we've been in the La nina or relatively weak el nino cycles of the soutern oscillation. Just coming out of it now, in fact, and I'm not sure whether the current el nino will be moderate or large. As you hopefully know, the ENSO cycle has regional and effects that get superposed on other climate signals. One argument for the "flatter" temps of the last few years is precisely that the ENSO effect is modulating what would otherwise be a warmer "noermal". I'm not asking you to take that on faith. But it is worth a looksee. Multivariate ENSO Index.

The ultimate point - for you and optimizer and others and is that "climate models" are not, and were never considered (by me at least) any kind of magic bullet proof of AGW. There are many independent lines of evidence that converge to paint the picture. As I analogized at some point above, the painting is expressionist or pointillist, not photoreal, but the end picture is still clear.

... I see a very pronounced tight little "climate science" culture grow in the media, academia and on the internet. They especially do not like geologists which is really sad; since without geologists "climate scientists" would have no idea the climate could change at all.

Perhaps you are thinking of specific individual climatologist/geologist relationships, but I find that particularly funny, since I know from personal professional experience that a generailzed application of this statement is simply false.

I could go on forever. But you won't listen nor see.

I hope I've demonstrated that I'm listening. But you are right in that I simply don't see what you see. It is likely that neither of our lenses is completely free of distortion. The most we can do is strive for objectivity as best we are able.

re: #1230 Optimizer

ls. You fail to explain why anybody should believe that lower CO2 levels should magically become dominant, just because some of it is being caused by industry.

CO2 can both lead and follow. There is some geologic evidence it does both, in positive feedback. As I stated above, CO2 is increasing at previously undocumented rates due to human contribution. The physics of heat trapping by CO2 is simple. What happens to the trapped heat is not as simply explained, but it would be a mistake to simply dismiss it.

"Point 2" did nothing to dispute the claim that humans have historically done better with somewhat warmer climates.

That actually wasn't the claim made, so I did not dispute it. The claim that humans may or may not "do better" in warmer climates is immaterial to whether or not we are causing climate to warm.

Your "Read the actual papers" is code for, "Either read through a mountain of papers by people who support my view or just shut up and believe what we tell you."

For the record: I do not speak in code. I have never said nor implied "just shut up and believe what we tell you." That is anti-science, and personal anathema to me. I would thank you not to attempt to put false words in my mouth or intentions in my head.

Welcome back. Last night's game of simultaneous chess was an impressive performance by you -- even if I'm not on your side. However, you seemed to pay more attention to the flamers and let my #1137 slide.

Let me add that, of course, I'm not saying there are no positive terms in the feedback, just that an impending tipping point has not been explained. Maybe I missed it.

The obvious negative term in the feedback is the simple increase in blackbody radiation as the earth heats up. That's a pretty strong term in the equations. If simple diminishing sea ice is a tipping point, then we tipped decades ago -- and that is not what the CAGW crowd is saying.

Using the AGW theory I can do the following:

I can construct a vessel within a vessel of which the inner vessel will hold a liquid, say soup, with a wall that is transparent to infrared. The outer layer will be reflective of infrared and a 100% CO2 filling between them.

If I pour a liquid that is hot into the inner vessel it will radiate infrared to the CO2 and at some time in the future I can come back and the liquid will be hotter than when I put it in.

First off, I'm sorry I didn't get back to you. In the time it takes me to write a detailed reply to someone, there can be multiple posts put up before I start writing the next one. Many times, a post that I wanted to get back to slipped through the cracks.

The black body part of the picture in the atmosphere is certainly important. It is also important in the water.

The argument for the tipping point is not just that we are loosing ice, but that conditions can arise such that when something would come around to refreeze the ice, it will ultimately not be strong enough to do so because all other forcing to melt the ice will win.

You objected that something needs to melt the ice first to start the cycle.

My response is that there has always been a melt and freeze cycle down there in a balance and now we are tipping the scales to melt. What would have melted and refroze before now melts more and refreezes less. Further, I am saying that we are forcing the balance to tip faster and faster to melt.

The picture is further complicated by the fact that the ice sheets do not heat uniformly and have very complicated interactions with melt water and sea water carving channels into them, that along with other mechanical stresses causes them to break up in very difficult manners. When these break ups occur, and they are happening now in the Antarctic as well as Greenland and the arctic, I believe that you linked to NSIDC data yourself which shows this.

When some city sized hunk of ice breaks off and goes into the ocean, it melts even more quickly. When the ice sheet itself starts getting carved up, it melts more quickly (under the same conditions) than if it were not carved up.

This is all a very non-linear thing to model and there is a great deal of work being done in an attempt to understand the underlying physics of the situation better. It is very difficult to predict, however, it also means that whatever the "actual" model of how fast it is going, must be more rapid than one that does not take these features fully into account. In other words, we know for a fact that any improvements to our modeling can only make the situation look worse, rather than better.

But those are details of calculating the specific case of how fast the melts actually are. Let's step back a few steps and look at general things we know are true.

We know that the ice melts, that it is happening now and that as it melts, it reflects less sunlight.

We know that there is more carbon in the air, and as a result, less energy reflected back into space means more heat in the air. More heat in the air and less ice, also means more heat in the water.

We have directly measured that this process is already happening.

Without writing a bunch of equations for you, let me say that yes indeed this mechanism that forces more melts can overcome trends to freeze.

There is another feedback that also needs to be taken into account as well.

As Siberia and Canada and Greenland melt, the bogs, which had been trapped under ice for millennia, are now free to release vast amounts of methane. This only accelerates the process. Methane too is a very bad GHG. So you have the issue of ice melts -> more methane -> it gets warmer -> even more ice melts faster.

No. That is false. The thing that you are missing is an outside forcing.

You could put imagine an open container of soup that you are heating with a lamp. The soup is at a certain temperature, but it cools by radiation and convection. However, the lamp keeps heating it. You could have this system in an equilibrium such that the soup stayed at the same temperature. In other words, the lamp heats it at the same rate that the soup cools.

Now using AGW, if I change the atmosphere that the soup is in, then it might not lose heat through convection or radiation as effectively, because the air is now trapping heat from the lamp. Therefore, the balance is shifted. The lamp is still heating the soup, but the soup can not cool as well. The soup gets hotter.

CO2's infrared reflectivity is a known value. More heat is getting trapped in the earth's atmosphere." I appreciate your reply. You still haven't explained why C02 is the dominate factor for driving climate, "holding heat" as you put it; over all the other natural factors all of a sudden. Those processes do not halt just because industrial processes put the C02 into the atmosphere. The temps rose out of the Little Ice Age also. This is a scanned page of a paper with chart cited in my husband's paper. He had to rule out climate change as a reason for a 6million yr old event he found evidence for on the No. California Coast.

How many times have I said here that there has been 22 ice retreats and advances in the last one million years. C02 concentrations are higher then today and remain high for millions of years on that chart -and ice has formed and grown despite. We also don't know how the climate acted in between major shifts let alone know how the climate "looked" in a century or a decade. It is a major assumption to say "right now" looks different then any other in the past as far as weather and climate goes. In fact we had in pretty modern human memory a Medieval Warm Period and a Little Ice Age that people wrote down words about. I have more to say; but for now this is it.

With sufficient CO2 density and in sunlight, quite possibly. On the other hand, you'll also lose heat from conduction through the glass and convection of the outer glass with the air. Even if your inner vessel is completely sealed and somehow floating inside your outer vessel, the ambient air cools the outer vessel through conduction and convection, and the cooler outer vessel will cool the CO2 in the gas envelope some, which will in turn cool the inner vessel. Likewise, the hot liquid will warm the glass of its container, in turn warming the CO2 envelope and the outer glass, and that heat can be lost to the outside air.

In short that system is subject to heat transfer in and out by radiation, conduction, and convection. That simple system is not quite as simple as it seems.

Well, you should be very careful about the sorts of systems that Thermodynamics applies to.

There are certain concepts that have no meaning except in the context of average values taken over many molecular actions.

For example: What is the pressure of an individual molecule? Pressure is the action of many molecules hitting into each other, or a barrier of some sort. One molecule on its own doesn't feel or exert any pressure on anything. Pressure is an inherently group property and something that arises out of the collisions of many many atoms or molecules.

Another example is heat. Heat is a measure of how much thermal energy is in a system. In the most simple case, and ideal gas, it is nothing more or less than an expression of the average kinetic enegy of the molecules as they whizz around in the tank. As they hit into each other, they are constantly exchanging this kinetic energy. Some go really fast, others more slowly. The individual kinetic energy of a molecule or an atom, does not account for the bulk properties of the tank of gas. It is only in an average over many atoms or molecules that the notion of heat has meaning.

So the short form is that Thermodynamics is written in terms of bulk properties. It only makes sense in terms of ensemble averages.

Got it?

re: #1242 JustAHouseWife

So, I would like very much to get back too our discussion.

I assure you that I have no animus for geologists.

You have claimed that wobbles in the Earth are sufficient to account for the heating we are now observing. I have claimed that these wobbles are very important, but do not account for the heating we are currently observing.

It turns out that my field is actually chaotic dynamics. So let's assume that we could go back and forth ad-nauseam about Hamiltonian chaos, strange attractors and locally stable orbits in phase space. Let's assume that such a conversation would be pointless in of itself and doubly pointless without an equation editor and triply pointless because it would enlighten no-one.

So I ask, if you have a new calculation that actually shows that in our current cycle, wobbles are sufficient to cause the observed trends in heating, that you link to it, or at least give me a journal reference. The majority opinion is that this has been ruled out.

If you do not, there there is nothing more to say.

I don't dispute that. Nor do I dispute that the earth was significantly warmer on average in Jurassic and other epochs. The poles were also ice free and there were shallow seas in different continental interiors.


C02 concentrations are higher then today and remain high for millions of years on that chart -and ice has formed and grown despite.

Back to point 1 from a few posts ago. DIO n't dispute that. There certainly are large scale cycles that drive climate on k-year to m-year cycles. Our current industrial CO2 surplus is signal on top of that.

. It is a major assumption to say "right now" looks different then any other in the past as far as weather and climate goes.

I was pretty careful in choosing my words above. We do not have any geologic evidence at this point of a CO2 rate of change as rapid as we have seen in the last century or so. Do I assume such has never happened? No. But we do not have any evidence it has. Should some geologic record show this, and also indicate zero or opposite global climate effects, taking into account all the other forcing factors as well, then there's a real counter argument to AGW.

This is also precisely why several of the "it's all about big natural cycles" arguments are useless. Short scale forcings and reactions - say major volcanic eruptions that depress climate a half degree for a couple years in one or the other hemisphere - get lost. On the other hand, and damn if I can dig up this plot - I have one somewhere that shows dCO2 concentration/dT going back some multi-k-years with references. Everything waggles nicely and gradually until the last century, where it blows the roof off. Having such would be a handy jumping off point for discussing the fidelity of those references.

re: #1216 Salamantis

OK Sal, Let's look at one of your painstaking details. Pretty much everything you write is crap, but let's look at this...

She then pointed out that sunlight played a minor part relative to air temperature at the poles due to the extremely oblique angle at which sunlight strikes them, the low sunlight energy absorption rate of ice and snow due to its high reflectivity coefficient, and the vast amount of atmosphere they must diagonal through, and that seawater played a minor part relative to air temperature as far as the Antarctic and Greenland Ice Caps are concerned, because, unlike the Arctic Ice Cap, they rest on land:

Uhuh, First off Sal, this was elaborating a point that I had explained to you after you had been multiply challenged on it and could not answer.

Also, this is your understanding of it, not exactly Zombie's. So let's focus on why you are wrong. Zombie is much smarter than you.

Your basic assertion is that sunlight is not one of the primary drivers because of oblique angles etc... This is not to discredit the importance of the atmosphere in these interactions but let's just look at what you said.

Here is the counter proof. There are still seasons up (down) there. It gets warmer in summer (closer to the sun) and colder in winter (further from the sun). Right? Do you deny seasonal variation? Do you deny there are seasons?

So we have gone from you not knowing advanced science, down to you not knowing calculus, down to you not knowing basic physics like why force is not an argument to even be mentioned here, down to you have failed the third grade notion of why we have seasons.

So Sal, let me put this clearly. I really don't care why you have chosen to make such an utter fool of yourself. However, it would be a very nice thing if you would stop.

Take the time to remember the third grade before arguing about this.

Ahh... but one more...

I then proceeded to demonstrate by empirical analogy why a gradual 7 degree C increase in global temperature over the next century would not even remotely approach sufficiency to melt the three ice caps in the next hundred years, given the evidence of the past hundred:

No Sal, saying something over and over again without being able to explain it only demonstrates that you don't have anything to back your statements up with. You proceeded to demonstrate repeatedly that you have no grasp of even the most basic concepts.

Take an intro to Geology dude! You are ignoring the past we do know about!

Not at all.

Q.E.D. M. R. B.O.L.O.G.N.A

Also not at all, you have demonstrated nothing.

Why don't you tell everyone how you calc and disregard the planet's wobbles?

The calculations are Hamiltonian analysis for a very large number of parameters. LIke I said upstairs, we are not now currently experiencing an orbital variation that could account for the observed heating. We discount it, because there is an insufficient energy budget, and as I have said many times, energy is conserved. Like I also said, unless you have a new calculation that shows otherwise, this has been ruled out.

So please stop hyperventilating and either post the journal paper with this new calculation, that contradicts everyone else's or stop, just stop.

re: #1256 JustAHouseWife

But even if wobbles are contributing, it doesn't alter the fact the atmospheric composition has changed and will also contribute to warming. I'm not a scientist, though I do follow along and try to comprehend what I'm reading, and I'm going to go with the physicist here when he sites basic physics. You can point to all the additional factors you want, but it's not going to change the increased GHG in the atmosphere.

re: #1240 ludwigvanquixote

Your reply is a great summary and the clearest argument I have yet seen in support of a tipping point. But it doesn't support the contention that the tipping point is near where we are now. If all the bogs were at the same latitude (or generally in the same microclimate) then one might make a case that they will all let go at some point. I see no one making that argument at a detailed level. This may be non-linear but that's just a hypothesis -- methane exists in lots of places in lots of latitudes/climates.

Also, the sea ice trends show no signs of non-linearity. The regressions of the sea ice plots don't look like they need a second-order term. Same for global temperature. If it's supposed to be accelerating, it's late.

So, the tipping point argument needs more than a good intuitive hypothetical argument. This is much too important to resolve without a lot of details and data. This is the point on which the urgency of immediate action hinges.

re: #1255 LudwigVanQuixote

Look, Ludwig, I’m going to try to give you some good advice, although, considering your obviously massive emotional investment in all this, it will probably fall on deaf ears:

When you are conclusively proven to be wrong about something you asserted, ADMIT IT.

It happens to all of us. I have in the past mistakenly typed the word ‘blastocyst’ when I meant the word ‘chloroplast’, and mistakenly included the nucleic acids in with the amino acids. When these errors were pointed out to me, I immediately acknowledged them. My willingness to do so caused people to grant me MORE credibility, not LESS.

Even in our discussions, I have admitted when I misplaced a decimal point, one time immediately after you pointed it out, and another time when neither you nor anyone else even noticed it – but I did. I also stopped asserting that solar cycles had more to do with global temperature change than greenhouse gases once Sharmuta proferred her Ecohuddle link, Which contends that solar irradiance has been pretty much constant lately, and the recent global temperature increases mainly have to do with the degree to which changes in atmospheric composition cause changes in how much of that solar irradiance is retained, and am studying the matter further. What I continue to seek on the matter, and have not yet found, is a graph correlating specific levels of CO2 in the atmosphere with specific rates of solar irradiation retention, with all other atmospheric constituents being held constant.

The point is, that I am less interested in winning, than having the correct view on an issue prevail, whether or not it is mine. This time, it just happens to be. When I am wrong, I admit it. But when I am NOT wrong, I refuse to lie and say that I am just to salve someone else’s injured ego. Veracity transcends personality.

Your contention that a 7 degree C rise in global temperature over the next century could cause the complete and total melt of all three ice caps, Arctic, Antarctic, and Greenland, and a sea level rise of ten meters, is quantums beyond the pale of current accepted science, as the IPCC report, the Bristol study, and several others to which I have linked have testified. In addition, Zombie demonstrated in

[Link: littlegreenfootballs.com...]

that as far as the Antarctic and Greenland Ice caps were concerned, since they rest on land, the effects of ocean currents are negligible relative to the effects of air temperature, and for all three, due to cloud cover, oblique angle, atmospheric insulation, and high reflectivity coefficient, the effects of sunlight are negligible relative to the effects of air temperature for all three.

Then I demonstrated by empirical analogy how a gradual 7 degree C increase in air temperature over the next hundred years was woefully insufficient to completely melt the ice caps, since, considering the air temperature and melt rate of the last hundred years, that 7 degree C air temperature increase would have to cause a 4921.25% increase in melt rate, which is as exactly, precisely as absurd as contending that subjecting an ice cube that takes 49 minutes to melt to air just 7 degrees C warmer would cause it to melt in a single minute:

Taken together, these two posts conclusively refute the ten meter scenario, and no amount of rhetorical posturing or ad hominem slagging the messengers will redeem it.

You’re NOT the Infallible Pope of Global Warming, and you should stop trying to be. It does not augur well for your appeal to scientific authority to apparently endeavor to morph your subjective and passionate personal perspective into some sort of quasireligious omniscience. Just because you made one prediction that proved to be empirically untenable does not mean that all your others are; science is not as brittle about errors as Biblical Literalists are about Scripture. In fact, science’s ability to learn and profit from its mistakes is a strength that dogmatic religion does not possess. Each assertion independently stands or falls on its own merits, and both verification and falsification lead to advance in empirical understanding. Please cease allowing the destructive seduction of pride and personal hubris to force you to get in your own way, and just admit that the complete ice cap melt ten meter rise within the next century scenario is utterly beyond the empirically possible pale. It’s not about your ego, it’s about the facts of the matter, as illuminated by the empirical evidence, and they are clearly and overwhelmingly against the ten meter scenario. As a result of simply admitting what by now everyone else reading these thread knows to be stupefyingly obvious, you will salvage your objectivity, bolster your personal integrity, and enhance your credibility, not just on the single issue of climate change, but much more generally.

Just as I stated when I began this post, I realize in advance that my good faith effort to assist you here will probably be to no avail, as it seems that you suffer from the personality fault of constitutionally being incapable of admitting error.

There are SOOO Many more affects to global climate than just thermo dynamics...you let yourself get wrapped up in one aspect of literally hundreds.

It is fun to watch however...

Do I profess to 'know' how to demonstrate that AGW is or is not ocurring...absolutely NOT...I understand all too well what is involved with modeling software for things MUCH simpler than AGW and recognize only too clearly that even these 'simple' modeling systems have too many variables to be used as a means of definite proof.

There simply has not been enough time to collect data from 'real' sources to demonstrate any true AGW. Using data sets from 30-50 or even 100 years is ridiculous when considering the global climate and all of the potential forcing agents that impact the earths global climate.

I can post plenty of links that refute such things as "polar ice caps receding at alarming rates" or "data from temperature readings being excessively 'corrected'. These are all indesputable facts...except when the 'other side' does not want to consider them as indesputable.

Bottom line...show a simple collection of data or even an experiment with CO2 that definitively proves that MAN has caused SIGNIFICANT impacte (read change) to the GLOBAL climate and you will have a convert (ME).

Look through my 'meager' postings...I have been generally lauded (updings) and don't use trash language...even as many who are 'regulars' do.

Dear Mr.Golem.

I learned Thermo 101, as you put it, in the physics department of an Ivy League university.

One of the things they taught me was the definition of Thermodynamics.

What kind of proof will you accept? What kind of smoking gun are you looking for, because in a complex system, it is liable to be a complex answer.

Let's start with some building blocks.
Do you refute that the rise in CO2 and other greenhouse gases in the atmosphere is due to human industry and activity?
Do you refute the IR opacity of CO2, and the greenhouse efficiency of other man-made pollutants?

Solar radiation, black body thermodynamics, CO2, etc..etc..etc.. These are but a FEW of the literally hundreds of variables that impact our climate.

That is not in contention. What appears to be in contention is the relative importance of each to the current situation. Some of these hundreds of variables can be discounted from the current situation by being too small in magnitude, or too long in time scale to matter. Some can be accounted for by being measured not to have changed. Does your proof constitute going down the entire list with peer reviewed research one by one? I think that can be done, given enough time.

Also, Sal, an analogy by definition is a relation between distinct ideas or situations. So there can be no such thing as an empirical analogy. That is an oxymoron.

1282 LudwigVanQuixote  Tue, Aug 11, 2009 7:47:02pm

What defines the last 100 years as the PERFECT climate for the planet...and anything before or after a radical change? This whole idea makes no sense...scientifically or otherwise.

re: #1278 Coracle

I refute that a "major" increase in CO2 and other greehouse gases is due to MAN...prove otherwise.

Are you familiar with the Keeling curve? Here.

The measured rise in CO2 over the last 50 years is consistent with the retention of 57% of burned fossil fuels. Slight fluctuations in the rate of increase track with the economic collapse of Eastern Europe in the early 90's. Current CO2 levels are higher than in the last 400,000 years from the record preserved in ice cores. We have fairly good estimates of how much CO2 we're putting into the atmosphere - how much oil/coal/biomass is burned on an annual cycle, and it is more than the observed rise. Anthropogenic source is supported by logic (i.e. if it's not, then you have to have two natural processes - one to absorb all the anthropogenic CO2 and one to emit enough to create the observed increase), and by (carbon) isotopic measurements, which show signatures of depleted C13 isotopes from fossil fuels in atmosphere.

Do you need refs for each item? Google Scholar will help, and so can I, perhaps after this week is over.

All of the above, according to pro AGW believers, can be based on 100 years of observational data or less. Taken in the context of our global climate and how the planet as a system behaves, that is like looking at a 1/1000 " line in a fossilized landscape and saying...see, this 1/1000" inch line indicates that the climate has been hugely impacted over the course of 5 minutes by a swarm of killer bees...(poor analogy but maybe you will get my meaning).

Interestingly The KT boundary is marked by the iridium anomaly, which is just such a tiny layer - thinner in some places, thicker in others, depending on the depositional environment, indicating a global disaster 65 million years ago. The climate at that time was hugely and literally impacted by 10 km asteroid.

What defines the last 100 years as the PERFECT climate for the planet...

That's an incorrect definition. Pre-industrial climate is the baseline against which we measure the change over and above natural cycles.

This whole idea makes no sense...scientifically or otherwise.

I agree 100%. The concept of "perfect" or "ideal" climate is completely non-scientific and, not coincidentally, not a component of AGW.


The planet has been and will always be in a state of change (except maybe when the sun turns into a red giant)...

re: #1237 Coracle

[by Optimizer (#1230)]You fail to explain why anybody should believe that lower CO2 levels should magically become dominant, just because some of it is being caused by industry.

[by Coracle] CO2 can both lead and follow. There is some geologic evidence it does both, in positive feedback. As I stated above, CO2 is increasing at previously undocumented rates due to human contribution. The physics of heat trapping by CO2 is simple. What happens to the trapped heat is not as simply explained, but it would be a mistake to simply dismiss it.

Now... you DO realize that absent some non-causal phenomenon (where action preceeds the stimulus that causes it) you've admitted/proven that CO2 is NOT a major driver of global temperature, right? If it "can both lead and follow" - and especially if it does "both" - it's obviously not the primary driver. Can you hear yourself?

As to the "positive feedback" bit, that's a lousy assumption, and at the heart of the problem with climate models. Positive feedback rarely occurs in nature, and if it existed the way they say it does in nature, the world would have experienced runaway global warming after the 1998 super el Nino. Instead, the temperature dropped right back down, stablizing for the last 8 years or so. Recent studies are pointing to the feedback being negative, which should surprise nobody, but is bad new for the guys who live off apocalyptic climate models, all of which depend on it being positive.

[by Optimizer (#1230)]"Point 2" did nothing to dispute the claim that humans have historically done better with somewhat warmer climates.

[by Coracle]That actually wasn't the claim made, so I did not dispute it. The claim that humans may or may not "do better" in warmer climates is immaterial to whether or not we are causing climate to warm. ...

Actually, the direct quote that you were responding to (or not responding to, to be precise) was, according to your #1223, "I see in the data that most of the life on this planet loves it when it is warm not when it is cold." (by JustAHouseWife) That includes humans, and you were clearly argumentative. Further, you're the one who commented on it, so don't complain to me about its relevance.

1292 Optimizer  Tue, Aug 11, 2009 10:14:32pm

re: #1239 MKELLY

Using the AGW theory I can do the following:

I can construct a vessel within a vessel of which the inner vessel will hold a liquid, say soup, with a wall that is transparent to infrared. The outer layer will be reflective of infrared and a 100% CO2 filling between them.

If I pour a liquid that is hot into the inner vessel it will radiate infrared to the CO2 and at some time in the future I can come back and the liquid will be hotter than when I put it in.

I'm afraid I have to concur with our alarmists here - this experiment ignores some basics - but they're not getting quite right, either. Power enters, and power leaves, with an equilibrium being established.

When something interrupts the flow, one way or another, a new equilibrium is established. The idea with a GHG is that less power is allowed to leave (in certain wavebands), causing an accumulation of (heat) energy. The increased temperature causes an increase in the radiation of heat in wavebands outside the CO2 window, until the power leaving is back to where it was.

One thing they like to ignore is that as those CO2 wavebands get blocked up, you can add all the CO2 you like, and it will no longer have an effect. Long before that, there's diminishing returns.

The calculations didn't add up to enough temperature rise to match the 1978-1998 interval, or to alarm people (depending on who you're talking about), and so they hypothesized "positive feedback", where H2O (which is the dominant GHG - a fact they don't like to talk about, unless they need it to help out puny lil' CO2) reacts to the CO2 effect in order to help out.

The problem is that "positive feedback" is wrong (as common sense would normally tell you, for a number of reasons), and that the dominant effects of climate change lie elsewhere. Humans are still pissing in the wind, when it comes to effecting the weather on a global scale.

My apologies to you folks who place much of their self worth in their mission to "Save the World".

re: #1291 Optimizer

Now... you DO realize that absent some non-causal phenomenon (where action preceeds the stimulus that causes it) you've admitted/proven that CO2 is NOT a major driver of global temperature, right? If it "can both lead and follow" - and especially if it does "both" - it's obviously not the primary driver. Can you hear yourself?

Sure. And I can also hear your simple mistakes.

This isn't brain surgery. CO2 can come from multiple natural sources. It can lead from one, which changes the climate conditions enough to trigger release from another.

As to the "positive feedback" bit, that's a lousy assumption, and at the heart of the problem with climate models. Positive feedback rarely occurs in nature

But it does occur, and when it does, we should pay attention.


and if it existed the way they say it does in nature, the world would have experienced runaway global warming after the 1998 super el Nino.

It looks like you are saying "It doesn't happen, but if it did it would happen this way"?
What makes you say that? What are your constraints?

You can't bake that cake, but it's a chocolate cake.

Instead, the temperature dropped right back down, stablizing for the last 8 years or so. Recent studies are pointing to the feedback being negative,

Which studies exactly? And what is the feedback mechanism?

Actually, the direct quote that you were responding to (or not responding to, to be precise) was, according to your #1223, "I see in the data that most of the life on this planet loves it when it is warm not when it is cold." (by JustAHouseWife)

I replied the way I did because whether any life loves or hates warmer climates is immaterial to whether humans are in fact warming the climate.


That includes humans, and you were clearly argumentative.

That is ironic.

Further, you're the one who commented on it, so don't complain to me about its relevance.

I didn't complain about its relevance. The statement was simply irrelevant to causes and effects of AGW, and I didn't treat it as if it was.You complained about my reply, after which I explained about it's lack of relevance.

re: #1292 Optimizer

My apologies to you folks who place much of their self worth in their mission to "Save the World". Sorry, but you're just patting yourselves on the back over nothing, hurting the most economically vulnerable among us in the process, and playing the proverbial "useful idiot" for the cause of socialism.

You are right Opto... I just realized that all of those years in graduate school where I was indoctrinated into the Lenninist reform physics community were a waste. I once had such noble intentions, but I have become a mockery of the physicist I had once hoped to be.

You see, as a young man, our commissar was actually a very beautiful woman, well girl really. Her name was Irena. She had the most beautiful smile, and the way her lip would curl, and her body shake with righteous fury when she said the world capitalist, was well, too much for me as a young man to be able to resist. It was her dirty blond hair and piercing hazel eyes coupled with a true and pure urge to create a workers paradise that convinced me - well that and the fact that she could be very "rewarding" of my orthodoxy.

I am so ashamed now to think on it. But since I am confessing to you, it was Irena who told me that my mathematical skills could aid the cause of revolution and atone for my intellectual status, if I would help promote the new order through helping to create and perpetuate a new Marxist/Lenninist pure form of climate science. She was so convincing,, and I was so full of hope of creating a new state for the people... Oh! How she would smile when my lip would curl when I said Carbon Dioxide!

Just personally, you should know it was the best sex ever.

So I became part of the conspiracy. Of course, once I was in it... Well, how could I get out? My grants depended on continuing my research and by now, Irena had a little revolutionary coming. I admitted that I had to settle down and take care of the collective. I hated the dishonesty of it as I fudged calculation after calculation, but hey, everyone else in the department was doing it too. I convinced myself it was ok to keep lying.

And it was scary... There were those scientists, brave souls who remembered what it was to scientists... They stood up for the truth. They disappeared. Irena explained it was for the good of the party and the good of the proletariat.

My orthodoxy began to slip and Irena left me for a more strict Marxist physicist. I wanted so much to prove myself to her and get her back.

So I, much to my shame stayed silent all of these years, and all of the lies about global warming, well they just became second nature.

But, Opto... You have saved me. I know I am risking my life by doing this. I can no longer keep the truth hidden. The only thing that is warming the Earth excessively is Bill Clinton. That's right. It is all because of his secret slave breeding program and slave girl flatulence.

I know I will be shot now. But please know, I will die a free man at last because of you!

Since the 1998 super el Nino made the world warmer, "positive feedback" should have triggered this viscious cycle. Since global temperatures returned to pre-super el Nino levels, logic demands that we conclude that this "positive feedback" does not exist.

Actually 2007 was a terrible year for the poles and the feedbacks were exasperated. NOW THAT IS ACTUAL EVIDENCE.

Sunlight, water, and ice: Extreme Arctic sea ice melt during the summer of 2007
D. K. Perovich, J. A. Richter-Menge, K. F. Jones, B. Light,

Here is the abstract:

The summer extent of the Arctic sea ice cover, widely recognized as an indicator of climate change, has been declining for the past few decades reaching a record minimum in September 2007. The causes of the dramatic loss have implications for the future trajectory of the Arctic sea ice cover. Ice mass balance observations demonstrate that there was an extraordinarily large amount of melting on the bottom of the ice in the Beaufort Sea in the summer of 2007. Calculations indicate that solar heating of the upper ocean was the primary source of heat for this observed enhanced Beaufort Sea bottom melting. An increase in the open water fraction resulted in a 500% positive anomaly in solar heat input to the upper ocean, triggering an ice–albedo feedback and contributing to the accelerating ice retreat.

Quanta are small things Sal.

Quantum leaps have to do with energy-absorbing electrons jumping between orbital shells of different energy level surrounding atomic nuclei. Therefore when I say that something is quantums beyond the pale, what I mean is that it is several orders of magnitude beyond reasonability. But of course you, the fucking physicist, are far too dense and obtuse to figure that out.

re: #1281 LudwigVanQuixote

So Sal, did you go out and raise the caps by seven degrees to see how much melted directly?

Also, Sal, an analogy by definition is a relation between distinct ideas or situations. So there can be no such thing as an empirical analogy. That is an oxymoron.

Your attempts to make your writing sound more scientific and hence gain more authority, might be better suited not just by using scientific words, but by using them in the correct order.

Empirical is opposed to theoretical, in that the empirical has to do with actual states, processes or events, while the theoretical has to do with hypothetical states, processes or events.

I drew an analogy between the theoretical melting of ice caps and the actual melting of ice cubes (note the word actual, indicating empirical). Then tonight, just to shut your obnoxious and overbearing ass up, I actually chilled one portion of my home to 65 degrees while allowing the other part to set at 77 degrees. I can do this because I built a rear addition to my home, and instead of connecting it to my central air unit, I have a wall unit in it to cool it, and a thermometer in that section to compliment my thermostat in the central-air-cooled portion. Then I took six ice cubes out of my freezer and set three each of them on six identically refrigerated plates in different sections of my home, and timed the melt rate of each. Direct observation and experiment.

The three ice cubes in the 65 degree portion took 16 minutes and 11 seconds, 16 minutes and 3 seconds, and 16 minutes and 9 seconds to melt, and the three ice cubes in the 77 degree portion took 12 minutes and 38 seconds, 12 minutes and 34 seconds, and 12 minutes and 23 seconds to melt (and yes, they all came out of the same standard icemaker on my fridge). Note that the ice cube subjected to the 77 degree temperature did not melt anywhere near 4921.25% as quickly as did the ice cube subjected to the 65 degree temperature. For that to have been the case, the ice cubes in the 65 degree section would have had to have melted in a single minute, and the ice cubes in the 77 degree portion would have had to have taken 49 minutes to melt. Or 30 seconds vs. 24 1/2 minutes. Or two minutes vs. 98. What is important is the ratio between the two melt rates.

Now, I realize that you will try your damndest to ridicule my little experiment, just like you ridicule anything that ANYONE says who dares to disagree with you. For instance, if I had posted Zombie’s answer concerning what constitutes heat transfer rather than she, you would have faulted it rather than praised it; that’s just how assholes like you roll.

But I actually got up off my ass and physically checked; all you've done is run your fucking mouth.

Now please show me the empirical evidence from the experiment where you jacked up the global average temperature of the earth 7 degrees C for a century and it melted all of the polar ice caps.

re: #1257 Coracle

What are the nature of the wobbles that are supposedly rapid effectors? Milankovich cycles are multi-k-year cycles and do not cause century scale changes. Are you talking about the Chandler wobble? Or something else?

Gaw! This is so frustrating. How do you know these things don't effect change at century scales? Every single process on earth is triggered by orbital conditions and they could take hundreds of yrs or thousands of yrs to see. Absence of evidence isn't evidence of absence! re: #1258 LudwigVanQuixote

The calculations are Hamiltonian analysis for a very large number of parameters. LIke I said upstairs, we are not now currently experiencing an orbital variation that could account for the observed heating. We discount it, because there is an insufficient energy budget, and as I have said many times, energy is conserved. Like I also said, unless you have a new calculation that shows otherwise, this has been ruled out. So please stop hyperventilating and either post the journal paper with this new calculation, that contradicts everyone else's or stop, just stop.

I will not stop. I asked you a question. What are your error margins? Now I am going to ask you again and I want plus or minus in YEARS you could be in error when you say: "we are not now currently experiencing an orbital variation that could account for the observed heating" IOW How the heck do you know that? If an orbital variation took place thousands years ago we don't know about; and can't know about maybe we are feeling the effects of it NOW. A massive earthquake like my husband discovered could have done it. That earthquake changed the whole coast line of California 6 million yrs ago. The science is not precise enough and the earth is too darn old for you to be so damn confident to know that "we are not now currently experiencing an orbital variation". You also said: Bull shit. What about the thawing period 500 million years ago? What about it? IOW you have to go back a half a billion years to prove that C02 drives temperature? You won't look at the last million years but you give me a period on earth that far back we still do not fully understand (Iceball/hot house stuff) when the continents and the oceans did not look anything like today and the breathable atmosphere was created and the data is very scarce? I suppose you know what the wobbles were like back then too. Again, going back that far in time you could be off by hundreds of thousands of years; Mountains can grow in that amount of time. Again you are giving the impression that this is all figured out when the science isn't that precise at all and still ignoring the good clear data we do have about Earth's past climate; and proposing a one degree rise in "global average temperature" which isn't even a real number; the planet isn't "alive"! Sheesh.

re: #1261 Sharmuta

But even if wobbles are contributing, it doesn't alter the fact the atmospheric composition has changed and will also contribute to warming. I'm not a scientist, though I do follow along and try to comprehend what I'm reading, and I'm going to go with the physicist here when he sites basic physics. You can point to all the additional factors you want, but it's not going to change the increased GHG in the atmosphere.

I hope "new the composition" does contribute to the warming as needed because the tropical plants I've had for thriving for several years in my yard froze and turned to black mush last winter when the thermometer said 0 C. I live in Southern California. BTW one of the physicists I know and talk to sends me pictures of polar bears in his emails because he thinks the geological record doesn't lie. He thinks we humans are due and could be romping with the bears in the snow very soon. "Soon" in geologic time that is; he thinks in epochs. We humans are living at a peak in the warm cycle there's no one alive we can ask how the climate acted per decade or century when it started on the down side last time. Extreme weather might be the norm. Very hot summers and very cold winters. I know you want to blame C02. The makes me ask. I am curious. Are we still calling the dramatic influence of this teeny tiny gas in our atmosphere Global Warming? or Climate Change?

re: #1305 JustAHouseWife
About those polar bears, one thing the alarmist crowd likes to ignore is that these bears have been around for countless thousands of years (at least according to anybody who isn't in denail about evolution, that is), and so have survived worse climactic fluctuations than we are seeing now. The idea that these cuddly-looking killers are in danger is pretty ridiculous, and the result of some pretty pernicious propaganda.

About those Ice Ages, that explains why there's so much talk about how we should reserve our fossil fuel supplies for the inevitable return of same. What? There's NO such discussion, about what to do about a major episode of global cooling when it's is well-established in the scientific community that it will certainly come within a countable number of centuries? Is there, perhaps, some anti-science agenda afoot here?

It's impossible to imagine the ecofascists behind AGW alarmism promoting pumping CO2 into the atmosphere under any circumstances. That kinda tells you that the agenda is anti-industry, anti-human, and anti-capitalist.

Funny thing about the hype about 2007. Even then the North Pole did not melt to an open water state. There's photographic evidence that the pole was open water several times in past decades. So even with this relatively low area of ice, it obviously didn't fall outside the normal, natural range.

re: #1298 Optimizer (Optimizer quotes in italics)

In case anybody else misses the point, as you apparently did, "positive feedback", in this context, means that when CO2 make the world warmer, that the warmer world then causes more CO2, which makes the world warmer still, etc.

That is the simplistic view, yes. But it leaves out imporant information. For example, one possible pathway for CO2 positive feedback - and please note I am not claiming this is the particular path followed in geologic history or today - goes like this:

Output from volcanic venting over time raises CO2 levels, and thus temperature.
Warming water has reduced CO2 solubility, and thus warming oceans release CO2 from a different reservoir, further warming the atmosphere.
This simplest system, balance could eventually be achieved by increasing evaporation and cloud cover reducing heat input, or reduction of volcanic output - which is dependent on internal geological proceses. Or, if negativ e forcings were weaker or slower than the positive, such a system could run away.

A system like this may be responsible for a "lead and follow" of CO2 in different episodes of geologic history. In addition, other initiators of warming, such as the known multi-thousand year orbital forcings, can trigger CO2 response in positive or negative feedback (warming or cooling the air and oceans). It's different only in what causes the initial temperature boost.

Since the 1998 super el Nino made the world warmer, "positive feedback" should have triggered this viscious cycle. Since global temperatures returned to pre-super el Nino levels, logic demands that we conclude that this "positive feedback" does not exist.

Positive feedback could only have triggered a runaway 'vicious cycle' if sufficient additional CO2 was released in one year due to the El Nino warming to cause additional increase in temperature over and above the ENSO seasonal variability, _and_ if that additional temperature rise were sufficient to maintain the positive feedback engine after La Nina ended. Since global temperatures returned to more average numbers after the El Nino, logic tells us that there are at least three possible conclusions. One is indeed that no positive feedback path exists. Another two are that such path(s) is/are slower and/or weaker than the El Nino effects, and can be shut down or reversed when El Nino wanes.

Remember, the AGW claim is that CO2 is the dominant effect, so that doesn't leave room for excuses.

To clarify: the claim of AGW is that CO2 and other anthropogenic greenhouse gases are the dominant cause of the last century's global warming trend.

re: #1304 JustAHouseWife

How do you know these things don't effect change at century scales? Every single process on earth is triggered by orbital conditions and they could take hundreds of yrs or thousands of yrs to see. Absence of evidence isn't evidence of absence!

Agreed. Absence of evidence means that there is no support for the contention, not that the contention is countered.

Another adage is that you can't prove a negative. I don't know that wobbles can't affect global climate at century scales, but I don't see any mechanisms that would do it, nor any record to back it up. I've asked you to clarify which wobbles you are positing as being a cause. On the other hand, the CO2 warming effect is simple and well understood. Why invoke a cause with no evidence simultaneously with denying a cause with evidence in hand? There is, so far as you have presented for wobbles, just as much evicence that the pulsations of nearby variable stars are the telling forcing factor in century scale climate change on Earth.

As an aside, it is certainly false that "Every single process on earth is triggered by orbital conditions". Volcanism, for example - which certainly affects our atmosphere and climate - is driven by earth's interior heat circulation and plate tectonics. I suspect you did not intend to be quite so broad with that statement.

No actual scientist would buy a POOYA strawman like that.

There's photographic evidence that the pole was open water several times in past decades.


THe north pole is a single point in the arctic sea region, covering millions of square km. Arctic sea ice extent looks at the entire area. The north pole itself - or any single point in the region - is not representative of the state of the aggregate whole.

Ludwig & Coracle let's move the vessel to a perfect vacuum. (the vessel is similar to a thermos in construction with the caveats I mentioned) By the way I never used the word glass.

So now no conduction and no convection to the exterior worry about.

IPCC says dF = 5.35 * ln (C/Co) If the CO2 encompassing the soup container goes from one ppm to one million ppm then I should generate roughly 74 W of extra heat. So whether the future is less than second or a millenium at some point I should see a higher temperature in the soup.

This is the crux of the entire discussion. If you tell me this cannot happen then AGW ends with carbon dioxide being vindicated. IF you tell me it can happen then the second law of thermodynamics is meaningless.

Energy is conserved. You can not generate extra heat. Now if you put that set up in sunlight (like the Earth is) You will find that the container warms faster than it could cool by radiation (you are now in a vacuum so radiation is what is left).

By adding more CO2, your soup really would get hotter under these circumstances. Absolutely.

1315 LudwigVanQuixote  Wed, Aug 12, 2009 10:12:59am

re: #1312 MKELLY

Please let me elaborate on my last explanation.

You have the soup starting at some initial temperature and it is in this set up. Let's say we haven't added the CO2 yet.

Because you have put the set up in a vacuum, the only way it can cool is by thermal radiation.

However, the whole set up is sitting in the sun. The sun is warming it up, also by thermal radiation.

Let's say that you have your set up sitting far enough from the sun, that the rate that it cools exactly equals the rate that it is being warmed by the sun. The temperature will not change.

Now add the CO2. Your set up now cools more slowly than it did before, because the CO2 traps the thermal radiation, from both the sun and the soup.

So now your set up is heating at the same rate, but cooling at a slower rate.

Therefore, your soup gets hotter.

Here's a whole page about the Milankovitch Cycles: [Link: jrscience.wcp.muohio.edu...] "The first stage, the Interglacial period, is often looked upon by scientists to be the period we are living in right now. SPECMAP describes this period as “A state in which, both sea ice and northern hemisphere continental ice caps are at their minimum extents.” ([Link: www2.ocean.washington.edu...] "... and it goes on. Not the much about the atmosphere or C02 but the water system on this planet. And Ludwig said something about heat budgets: the page says: "The preglacial state begins when there is a “decrease in northern hemisphere radiation, which leads to freshening of the Nordic Seas” Hmmm. More fresh water when it's warm? Coracale: More like the CO2 warming effect is simple and well understood in a computer model. Talk about lacking. C02 doesn't warm anything; the sun warms the earth and the "warm" is held back from returning to space by GHG concentrations in the atmosphere-water vapor is the most important. The turbulence takes care of that "heat" real fast and so does the sun going down every night were temps could differ night and day by 30 degrees or more. And then there are clouds. And it is VERY cold up there where you imagine the C02 hangs out. It's so hard to measure temps in those layers! See I understand what it takes to get good data and you guys go on about 1.7 degrees. Then you say: "but I don't see any mechanisms that would do it, nor any record to back it up." What a circle jerk. first you have to show us that "this rapid warming" is unusual. North America was covered with ice three miles thick; and in an ice age "global average" temp was what? I think only 4-6 degrees lower then right now -correct me if I am wrong; and you want me to get worked up over "what you think" is a "rapid" "warming" that may be 1.7 degrees different/more then what might have been 100 yrs ago? Can you tell if one room is 1 degree warmer then the next? Did all those people 100 yrs ago write down 50 degrees or 51 degrees when the temp was 50.5? What if they couldn't find their glasses? do you care about error margins at all? You should if there is hysteria attached to it. I hear you Optimizer!

re: #1316 JustAHouseWife

So in the short form you are claiming that Milankovitch Cycles (and further, a heretofore unobserved Milankovitch Cycle, that popped out of nowhere, with out us noticing) are more likely to be causing rapid warming than the gigatons of extra CO2 in the atmosphere and the known facts (from direct observation and QM) of CO2's absorption characteristics. Further, you are saying that because of this, we should discount Carbon as an important issue.

What you are saying is like a cop, who upon seeing a corpse, face down in an alleyway, with twelve bullet holes in it, concluding that there might have been a death by natural causes (after all the poor fellow could have had a heart attack before being shot) and that therefore we should not get hysterical about a murder investigation.

Now, let's get this straight.

Show us a journal paper with a new calculation that shows that Milankovitch Cycles are likely to outweigh the known forcings caused by CO2, or all you are doing is saying that you do not want to look at the facts.

"Not very smart"? You were doing so well in staying above the gutter that LVQ lives in, but I see that when you are in a bind the insults come out from you, too.

Ironically, there is not an inconsistency between someone being ecofascist and being anti-human, so you're not being very smart here, yourself. It's called "self-loathing". It's immoral and irrational (which is why I'm not among them), but it happens. For an extreme example (but not the MOST extreme one), see [Link: www.vhemt.org...] You want to malign skeptics because Creationists take the same side? These are some of the people in your camp. What would a guilt-by-association argument conclude about you?


As to your comment about Arctic sea ice, you still leave yourself with a "positive feedback" reaction that has an unexplainable 9 year time lag, and which has decreased (even according to you) in recent years, instead of spiraling out of control. You haven't explained how this is supposedly a "strawman". In actuality, it is EXACTLY what the "positive feedback" mechanism is supposed to be all about. It's not even an analogy or metaphor.

To paraphrase you, "If the north pole melts, it's evidence of the end of the world - unless it's in the past, and doesn't support what I'm trying to assert". Nice bit of logic there. "Pay no attention to that man behind the curtain!"

I don't have to read the paper to see its evangelical nature - It's evident in the abstract you quoted. Rather than observe the phenomena, and derive conclusions from it, they openly start with AGW theology, and the point whole is to attempt to find statistics that will support that dogmatic assumption.

It is just like arguing with a creationist.

You bring up a talking point. It gets explained as scientifically wrong, and you shift to another, or distort. When pressed, rather than blathering about the Bible, you blather about left wing conspiracies and anti oil agendas.

re: #1308 Coracle

You provide additional detail about "positive feedback" mechanisms, which is fine, but it's fairly superfluous to the discussion. The germain point is simply the claim that there IS "positive feedback."

Except for this bit: "Output from volcanic venting over time raises CO2 levels, and thus temperature." Obviously, a constant amount of volcanic venting would not change the CO2 equilibrium - so it would not effect the CO2 level. The volcanic venting would need to increase, and I don't think anybody's claiming that. I say this as a POI; it is also superfluous.

Regardless, you can't obfuscate the non-causal nature of claiming that CO2 can either lead or lag temperature differences (and still be responsible for them) by adding details to the "positive feedback" mechanisms. In the real world, responses FOLLOW stimulus; it's that simple.

As to your "1998" argument, if insufficient CO2 was released in one year to cause an increase in temperature, than the positive feedback mechanism is already "out-of-business". Further, the slower/weaker argument has no bearing. An increase of temperature occurred, and therefore - if "positive feedback" exists - "positive feedback" should have been triggered immediately. You couldn't ask for a more well-defined trigger for runaway warming, by "positive feedback" theory. If anything could trigger it, 1998 would have. By what magical theory does the end of El Nino override "positive feedback". Ain't no mechanism in the "positive feedback" hypothesis that would respond that way.

And yes, I DID leave out the abusive tripe. My example of what might have been said was purely hypothetical. I don't really expect scientists in this field to have studied much about feedback systems, and so it would be unfair to get abusive about it. Even if it was "fair", I think my record shows that I still wouldn't get abusive about it, unless I was provoked. I'm no LVQ.

I guess I missed the news reports about crops being harvested in Greenland these days. Perhaps you could point me to one?

I understand that parts of Greenland are seeing melting. There have also been reports that in other parts of Greenland that the ice has thickened, with the net result being pretty much nil. If it wasn't, the rise of ocean levels would have accelerated, whereas the opposite is the case.

What is lacking is evidence that any of this is out of the realm of natural variability (especially because of that pesky Viking thing).

re: #1316 JustAHouseWife

Coracale: More like the CO2 warming effect is simple and well understood in a computer model.


You do not need a computer model to calculate CO2 warming effects.
The opacity wavelengths of CO2 can be measured spectrally. The thermal emisison of the earth in those wavelengths can also be measured directly. Thus the amount of heat reflected by CO2 in the atmosphere can be calculated pretty simply. Refs for these quantities are not hard to find. Don't take my word for it, though. You can do the calcs yourself.

The turbulence takes care of that "heat" real fast and so does the sun going down every night were temps could differ night and day by 30 degrees or more. And then there are clouds.


Diurnal cycles and weather system excursions neither support nor refute anthropogenic climate forcing.

And it is VERY cold up there where you imagine the C02 hangs out. It's so hard to measure temps in those layers!


Yet it can be and is done. And even so, it is not the temperature of the upper atmosphere we are concerned with so much as its thermal IR absorption and reflectivity.

Then you say: "but I don't see any mechanisms that would do it, nor any record to back it up." ... first you have to show us that "this rapid warming" is unusual.


Hang on. You are the one saying it must be due to 'wobbles', and is therefore normal. But you provide no mechanism or evidence to support that contention. Your Milankovitch link says nothing about century scale cycles.

...you want me to get worked up over "what you think" is a "rapid" "warming" that may be 1.7 degrees different/more then what might have been 100 yrs ago?

I have made absolutely no claim that the 1998 El Nino had any effect whatsoever on the last 3 years of arctic sea ice. That canard is entirely yours. Feedback systems for sea ice melting have to do with warming of the arctic waters and the shrinking of the ice exposing more open water to warm. If you'd read any of the papers or explored the links I provided, you'd know that.

Here are some things we all can agree on:

1) Global temps have been rising for quite a while now.

2) CO2 has been rising for about 50 years at a gradually increasing rate, and some of this is anthropogenic.

3) Both sides on the AGW argument have made huge mistakes in their presentations (and that's putting it nicely). I'm referring to the debate at large, not LGF comments.

I think that anyone who focuses on the arguments for one side will likely be converted to the other side, as many of the arguments are too hyper and counter-productive.

Here's where I think the whole thing hinges. For AGW to be catastrophic, it needs to accelerate. This is commonly presented as it's about to reach a tipping point. My problem with this is that if you look at sea level, the ice caps, and global temps, the trends are all look pretty linear. If a simple extrapolation is accurate, things are just going to get a bit warmer, sea level will rise a few inches this century, the Arctic ice cap will continue shrinking but not disappear, the Antarctic ice cap will continue growing but not much. That isn't catastrophic.

I think it depends on what you're looking at. Global temps, perhaps. Arctic sea ice has taken quite a dive since 2007. There are a number of posited tipping points, though none have irrefutable evidence. I'm a little more circumspect about them than LVQ. The real problem with most tipping points I am aware of is the only way we could currently verify one would be to cross it. It would truly suck to be right about such a thing.

If a simple extrapolation is accurate, things are just going to get a bit warmer, sea level will rise a few inches this century, the Arctic ice cap will continue shrinking but not disappear, the Antarctic ice cap will continue growing but not much. That isn't catastrophic.

Yes and no. Given a long term linear trend - and discounting any global or large regional catastrophic trigger, certain local and small regional ecosystems will become increasingly stressed, some to the point of failure. "We" as a species would likely adapt, but some species, and some economies likely wouldn't.

re: #1333 Pythagoras

I don't have a good answer about tipping points. Best I can say is that plausible tipping point mechanisms need research to determine if they are realistic, and if so then are they likely and/or imminent. Unfortunately, the main way to determine likelihood is forward projection of climate and/or feedback and dependency models, and you reflexively lose a large number of people as soon as you say "model".

The nsidc plot is interesting from the site- it measures:

Monthly Sea Ice Extent
This graph plots ice extent anomalies (the difference in the extent for the month minus the mean extent for that month over 1979-2000) for the most recent complete month. The trend, in percent change per decade, is obtained using least squares regression, and a 95% confidence interval for the resulting slope is given.


This is a slightly different measure than figure S3 here, which measures summer vs. winter ice separately and shows both 2007 and 2008 September (end summer) to be quite nonlinear with the previous 25-odd years. Looking at figure S2 on the same link and the "Arctic. Daily" plot from your link, you'll see that 2008 as a whole was closer to 2007's anomaly than the 1979-2000 average, and 2009 is so far somewhere in between. My second link a few posts back to the 2009 arctic outlook july report was missing the last "p" of ".php" and doesn't work, but it shows a similar plot, ending a little sooner than yours. My ref showed 2009 ice trending closer to 2008. Your more current data shows 2009 trending to in-between the average and 2007. We'll have to see what the summer's end holds to see if the current year continues the past two years' summer anomaly or returns to a more linear trend.

Actually just to clarify for you. The only thing I said about the actual tipping point was that it must exist, and that there is great debate as to where it is.

Pythagoras is correct, that we must have an accelerated trend in order to have one. We do have an accelerated trend from albedo loss alone.

Mathematically, the best way to convince yourself that a tipping point exists is to remember the damped driven oscillator from classical mechanics. Even though the real system is vastly more complex and lives in a much higher dimensional phase-space, the mathematics is sufficiently similar to make the general point.

For any driven oscillator, there is some amount of damping that will cause it to wind down exponentially. In this analogy, that critical damping is the tipping point.

re: #1334 Coracle

Excellent! I had not seen either of these. I'm possibly OCD on the sea ice data because I genuinely think the jury is out on the whole thing and the sea ice is one of the few universally trusted data sets. The best reference is to download the CSV from here:

[Link: www.ijis.iarc.uaf.edu...]

You can compare years by cutting and pasting to line up the same day on different years on the same rows. I think 2009 will track close to 2005 for the next few weeks. Here's why -- look carefully at the arctic ice concentration map here:

[Link: nsidc.org...]

Zoom in and look for pixels nearing the 15% threshold. (Tangent -- I highly recommend dropping $500 on a 1024x768 projector. I couldn't live without one.) I've been doing that for a long time and there aren't that many compared to a few weeks ago. Thus, it's pretty easy to forecast that the next few days won't show a big drop. Also, the temps here:

[Link: www.athropolis.com...]

have been showing a steady drop in the last week. Alert hit 0c earlier today (but doesn't show the temp right now). So, the 2009 minimum Arctic sea ice extent (which seems to be the measure to watch) may show dramatic recovery this year.

And that means almost nothing. Besides being just one data point in a long trend, you can see why it happened by watching how the ice moved over the last few months. The current that pushes it past Greenland and out into the gulf stream just didn't seem to do it's job this year. That has nothing to do with global warming -- but it is the reversal of why 2007 took such a hit.

So, I still wait obsessively for the jury to return.

Agreed. I say it as there are more feedback "terms." It's a debate worth having and I am interested in seeing the case made. The tipping point arguments I've heard (present company excepted) have been from the screamers. "We've only got 4 years ...!"

As I've said, both sides have their, "with friends like these, who needs enemies," allies. But the tipping point arguments are absolutely crucial and cannot be left to the uneducated. I build models for a living and I'm not going to reject a projection just because it's a model. If we're looking at exponential growth, make the case. But remember, the blocking of IR radiation (through scattering, jeez I wish people would say it correctly) is a logarithmic function of CO2.

As to the subject of feedback, I thought I had outlined pretty clearly that (as the most elementary control theory prescribes, and any second year engineering student should know) "positive feedback" systems, such as is modelled in ALL the alarmist climate models, are inherently unstable. What that means is that it just takes the meagerest of excitations to set off a runaway response.

I added the observation that the El Nino of 1998 represented the "mother of all excitations", and yet it still did not produce a runaway response. It should, therefore, be obvious to anyone with a second year engineering education that the "positive feedback" aspect of these climate models, which is the aspect of these models that generate the alarmist temperature increase predictions, cannot possibly be correct.

One need not be some right-wing Creationist zealot to come to this conclusion (obviously, since I do not fall into that catergory) - one need only be a savvy consumer of government-provided information. As with any kind of consumer, one should ask, "Does what the provider is telling me add up?" In this case, the answer is clearly that it does not.

Perhaps part of the problem is that there is a lack of people with that second-year engineering education (including, perhaps, scientists), but the basic concept is one that should be understandable to the layman.

You have not really provided any kind of technical rebuttal to this. Are you claiming that positive feedback does NOT make a system unstable? Or that the 1998 El Nino does NOT represent an excitation to that allegedly unstable system? 'Cause I would have thought that those things are both pretty obvious. Or are you just chosing to ignore that this is, in fact, a system, and that basic control theory applies (a choice that I would say is equivalent to choosing to believe in supernatural magic, BTW).

re: #1333 Pythagoras

... LVQ gave a credible outline for possible mechanisms (ice-albedo & methane from bogs) but I need more.

You're kidding, right? LVQ gave an argument that would lead one to expect ice to melt at -25degC. That was credible? Maybe he can sell you a perpetual motion machine next.

By the way, the ice trend does look linear. Check on the right hand side here:

[Link: nsidc.org...]

That's a good link, and there are two things that should be noticed. One is, if you look on the left, that the sea ice is a pretty contiguous mass, and that the North Pole is pretty far in from the edge.

If you keep in mind that image, and put it in the context of photos from 40+ years ago showing open water at the North Pole, it becomes clear that the sea ice picture up there has a pretty broad natural variability.

Secondly, if you look at the graph on the right, it IS pretty linear. But the thing to notice about it is that it STARTS at about the same time that the warming trend. If it went back further on the timeline, it's linearity would certain not be preserved. Further, since that warming trend has been stalled out for close to a decade, we can expect the most recent curve to appear to be bottoming out (plus noise) as more data is tacked on in the years to come, and to reverse if a cooling trend develops.

That being said, the pattern of sea ice has to do with more than just temperature. Shifting ocean currents can push the ice toward waters that are at a different temperature than the year(s) before, for example.

re: #1337 Pythagoras

... I'm possibly OCD on the sea ice data because I genuinely think the jury is out on the whole thing and the sea ice is one of the few universally trusted data sets. ...

And that means almost nothing. Besides being just one data point in a long trend, you can see why it happened by watching how the ice moved over the last few months. The current that pushes it past Greenland and out into the gulf stream just didn't seem to do it's job this year. That has nothing to do with global warming -- but it is the reversal of why 2007 took such a hit.

So, I still wait obsessively for the jury to return.

I actually have nothing against people having their pet obsessions, but in the AGW context, there are a number of things that seem like they are never talked about, but should be kept in mind about Arctic sea ice:

1) The North Pole was first explored about 100 years ago. Any kind of semi-regular observation of what goes on up there started decades later. So we've only really seen about 50 years of history for that area. The physics of the situation is such that physical evidence of what has happened there in the past does not last for more than a few years.

2) Within that 50 years we know that the ice situation has varied wildly (I keep talking about old photos of open water up there, which hasn't been seen again in a very long time).

3) The amount and pattern of ice is unpredictable. As you sit awaiting with bated breath, it's because there is no model that can reliably tell you what to expect.

4) There are factors at play besides temperature (as has already been discussed).

5) There is relatively little ice there. 99% percent of the Earth's ice is either on Antarctica or Greenland.

6) When sea ice melts, it does not effect the ocean level.

So, in summary, whatever's going on with the Arctic sea ice (which isn't much) is pretty irrelevant to the AGW discussion - dispite all the hype you see about it, from time to time. Nobody knows what's normal up there, nobody knows how modest variations in global temperature effect it, and all we really know is that it cannot possibly cause coastal flooding (sea rise).

re: #1335 ludwigvanquixote

Actually just to clarify for you. The only thing I said about the actual tipping point was that it must exist, and that there is great debate as to where it is.

I missed any defense of that statement you may have made, but if it's anything like your argument that claimed that 7degC of global warming would melt the Antarctic ice cap, I can sount myself fortunate.

Any reasonable person would be extremely skeptical of "tipping points", for two reasons. First, no such thing has ever been observed. To suggest that the conditions never existed before is to apply some sort of magical property to the CO2 specifically put out by industry. CO2 levels have certainly been this high, and higher, before, and no tipping point has been shown to ever have happened. The whole concept is highly speculative, at best.

Second, we can observe that the idea of tipping points emerged after years of proponents "crying wolf" about AGW, with its apocalyptic consequences stubbornly refusing to show. Suddenly the story changes to "You don't see a problem, and you won't for a long time, but if you don't listen to us, Blam!, disaster will finally show up all at once!" You'd have to be a child to buy into that. The main purpose of the "tipping point" concept is to eliminate both any sort of timetable for the dire events they foretell and any requirement of physical manifestation of thses dire events leading up to it.

Pythagoras is correct, that we must have an accelerated trend in order to have one. We do have an accelerated trend from albedo loss alone.

In the real world, global temperatures have decelerated to the point of stalling, and the normal ocean rise has decelerated as well.

Mathematically, the best way to convince yourself that a tipping point exists is to remember the damped driven oscillator from classical mechanics. Even though the real system is vastly more complex and lives in a much higher dimensional phase-space, the mathematics is sufficiently similar to make the general point.

For any driven oscillator, there is some amount of damping that will cause it to wind down exponentially. In this analogy, that critical damping is the tipping point.

I am quite familiar with the phenomenon of a damped oscillator, and if there is any connection to that and "tipping points" you have a lot more explaining to do. Enough damping stops the oscillation in such a system. Sure. What's that got to do with "the price of tea in China"? By it's very nature, a "tipping point" refers to a decidedly non-linear system, and you give an analogy that is a linear system. That makes no sense at all.

1344 Coracle  Thu, Aug 13, 2009 12:22:00pm

I hope this is worth one more try.

Let's take a simple model.

Imagine a sinusoidal signal of Y vs time, Call this "Seasonal Variation" oscillating a full wavelength from -10 to +10 over a course of a year, year after year. Starting at -10 at time zero, thus Y=0 at month 3, 10 at month 6, 0 at month 9, and -10 at month 12.

Superimpose that on another, longer sinusoid, going from -1 to +1 on a 2 year cycle (twice the wavelength). Call this "Large Cycle". If the cycle starts at -1 at time zero,

At random intervals, LC spikes or dampens - say a multiplier of 0.5 to 2 every few years

Now add have a linear increase of +0.1 per year in Y. This is our "forcing factor", resulting in a gradual slope upward of our modified sinusoid.

Next - a positive feedback trigger. For each day Y is above 12, a quantity of 0.01 is added to the forcing factor.

Y fluctuates constantly, but the trigger is only pulled when Y is greater than 12. The result increases the forcing factor by some increment, making it more likely - but not guaranteed, that the next year's maximum will cross y=12. If the reservoir pulled by the trigger is limitless and the effect of the pulled trigger unchanging, then eventually more and more of the yearly cycle will cross the trigger threshhold, and the system will blow up - i.e. a "tipping point" will be reached. This is not likely to happen the first time that threshold is crossed - especially during an anomalously high LC year, since the positive feedback is shut down whenever the Y goes below 12, and "normal" LC will not push it back up high enough for the next year(s).

The gradual slope of our forcing factor will eventually guarantee we cross y=12 for more and more of the sinusoid's peaks, and the random spiking or damping of LC may aggravate or lessen some yearly peaks.

Clearly natural systems are far more complex than this, but this is the type of feedback mechanism I am talking about.

Apply the analogy to the case of, say, arctic summer sea ice, the positive feedback comes in the form of lessening ice cover exposing more water to warming, allowing more ice to melt, and a natural limit to the feedback occurs when the ocean is ice-free. In this example, there is no "catastrophic" result, other than an ice free arctic summer sea, with the whatever ecological impacts that might have.

For the release of trapped greenhouse gases from permafrost, the trigger would be whatever temperature thaws the permafrost enough to initiate release. I don't know what the rate of release of what gases would result, nor how big that reservoir is, so I wouldn't hazard a guess about the magnitude of feedback or the runaway conditions there.

Thus I contend that a single given anomalous year, one that in fact does pull one or more feedback trigger during its hottest period, does not of necessity initiate a runaway if the trigger is temperature limited, and the cumulative effect of the pulled trigger is not enough to become self sustaining year after year when the anomaly goes away.

As for "tipping point" predictions, if you know everything about a system, then calculating such runaway points is easy. Clearly we do not know everything terrestrial climate systems, so identifying and predicting triggers and tipping points is, exceedingly difficult. Is it worth trying to figure out at all? That is a value judgement to which my personal answer is "yes". As I said above, it is, unfortunately mostly model based at this time, and also, as I said above, unlikely to be convincing to anyone with an inherent distrust of models. Or, for that matter, with an inherent distrust of modelers.

Finally, as I also said above, The only proof that will be 100% acceptable to most people would be the actual crossing of a tipping point, at which time it would pretty much suck to have been proven right or wrong.

That link is for sea ice in the Arctic, and I have already expounded on how irrelevant that is. 90% of the world's ice in in Antarctica, most of which is nowhere near warm enough for ice to melt year 'round despite your having pointed out that is has "summer" (that was a corker!).

1346 Pythagoras  Thu, Aug 13, 2009 3:32:04pm

re: #1344 Coracle

I have no disagreement with anything you've said. Mechanisms such as these make perfect sense. A tipping point is plausible. A trigger at Y=12 can be masked for a long time and then finally come into play and then take off. Many systems have non-linearities in them and the kind of mechanism you describe is pretty normal stuff.

Furthermore, I am not one of those obdurate folks who cannot be convinced by anything short of seeing it happen.

But at a detailed, quantitative level the case has not been made that we're near a tipping point. Ice melting and methane being released (and other things) has happened significantly in the past and we see no acceleration at all. Everything is tracking pretty linear.

I'm not giving you the "global warming stopped 10 years ago" bit nor the "sea ice is recovering from the 2007 low" routine. I think we agree that these are just wobbles around a straight line and anyone can cherry pick which ones look good for their side at that time. But the lines are straight over the last few decades. Sea ice, sea level, global temp -- all straight.

So, the argument that this is about to turn a big corner cannot be made with a simple curve extrapolation. The higher order terms just aren't there.

So, we need some details about a threshold were getting close to. The methane bit has the best chance. I don't see anything special about any particular level of sea ice. 5 million sq. km. in the arctic isn't a tipping point, nor any other level. The delta albedo tracks with delta ice.

If someone could make a detailed case that we're, say, 5 degrees C below where a huge methane bog in Siberia lets go, and wade through a projection how this will track (including details about how long the methane lasts in the atmosphere) I'd be VERY interested.

But I don't see that made and, to me, that means the case for a tipping point has not been made. Sure, it's plausible. It could happen. It might happen. So might lots of other things. But it seems a long way from likely.

1347 Coracle  Thu, Aug 13, 2009 4:11:19pm

Pythagoras, I have no argument with your position. I'm not versed well enough in the various tipping point scenarios or research to make a cogent argument for or against. Perhaps over time as I read more broadly I will be able and willing to make a better case in either direction. I think the linear case is still locally and regionally problematic, as it is occurring faster than some natural systems - say coral reefs - can adapt.

But I agree, we need more data, more studies of mechanisms, potential reservoirs - and potential sinks - of GHGs to be able to make a clear case either way.

1348 Pythagoras  Thu, Aug 13, 2009 5:02:28pm

Wow. One Thousand Three Hundred and Forty Seven comments in, two people who are, more or less, on opposite sides have reached some agreement -- and a middle of the road one at that. And I concede that the natural systems adaptation rate is another possible issue. Extinction has it's own obvious tipping points too (with the non-linearity of the odds of sexual reproduction and all that.)

Thanks. It's been a pleasure. Have a virtual beer on me. I do have a deadline I've been neglecting, so I'm going to let this go now.

re: #1344 Coracle
This seems to explain pretty adequately where you're coming from, and it's nice to see some civilized discourse.

I believe there is a lack on connectivity between the phenomenology you describe and the real world, in two main ways. Just to be clear, unlike the rantings in certain other posts, I'm not characterizing what you're saying here as a "psychotic episode", or anything.

The first problem is that in ALL the climate models whose predictions are expounded by the alarmist community, the primary mechanism in "positive feedback" is NOT as you describe. You're focusing on things like albedo changes and melting permafrost, but the "big dog" is all about water vapor. Since the added water vapor comes from the evaporation of ocean water, there's no "tipping point" kind of phenomenolgy involved. The other part of it is cloud formation where, yet again, it's not that kind of situation.

Secondly, as to the non-linear kind of phenomenon you are focusing on, there are a several problems there, too. Most importantly, the effects you decribe occur on a LOCAL level. In aggregate, in describing the global effect of what's going on, the effect would come on gradually, not suddenly, since the effective area of the Earth that was effected would change gradually.

By way of example, it's not like there's some all-important region of permafrost in Siberia that, after reaching the critical temperature for the requisite amount of time, would suddenly release all of it's methane into the air, over the entire region, with the effect being a sudden change in the temperature history of the globe as a whole. (But you can probably find someone caught in a fit of "I'm saving the world" hysteria to claim exactly that - as though permafrost has never melted before - anyway.)

So when we consider THAT, any kind of talk about "tipping points" should be treated with extreme skepticism. Of course, there are other reasons, besides which are both technical (like there's no record of one ever happening before) and the psychological (it emerged as a way to stick with the dogma, despite failed predictions).

Another problem is that the albedo of the Arctic is really not very important, since it covers a (relatively) very small projected area of the Earth, from the perspective of the Sun. This is especially so, with that area being zero for a good part of the year. Funny how small variations of solar insolation are discounted, but small variations in effective albedo (which can only have an identical result) are not.

As to methane from permafrost, it's established that methane is a more potent GHG than H2O or CO2, but it exists in such small amounts (likely even after the melting of significant permafrost areas) that it doesn't amount to a "hill of beans".

You also seem to have the impression that once a gas is released into the atmosphere that it simply stays there forever, not needing to be replenished for the concentration to endure. Yes, some of them can stick around for, maybe, decades, but that's nothing to panic over.

Anyway, whereas the DOMINANT modelled "positive feedback" effect as via water vapor, and whereas the runaway effect of a system with positive feedback MUST be unstable, and whereas the 1998 El Nino gave a large stimulus to that supposedly unstable system. and whereas no runaway temperature rise ensued, THEREFORE, we must conclude that the dominant positive feedback mechanism that is used in climate models does not exist, and that therefore, the said models (with all their alarmist predictions) should be considered invalid.

1350 Coracle  Fri, Aug 14, 2009 5:33:12pm

re: #1349 Optimizer

The first problem is that in ALL the climate models whose predictions are expounded by the alarmist community, the primary mechanism in "positive feedback" is NOT as you describe.

Since I have amply demonstrated that I am not an alarmist, I have neither the need nor desire to defend potentially faulty models they may use. I tis abundantly clear that some models are quite flawed, and no model is ever perfect. It is also quite clear that models in general can be quite useful when their limitations and caveats are taken into account. My question to you is, is there any global climate model you would trust on any level? If the answer is "no", then any discussion of models must end here, because there is no possible middle ground between us.

You're focusing on things like albedo changes and melting permafrost, but the "big dog" is all about water vapor. Since the added water vapor comes from the evaporation of ocean water, there's no "tipping point" kind of phenomenolgy involved. The other part of it is cloud formation where, yet again, it's not that kind of situation.

I'd like you to do me a particular favor. Take a look at the data in this link. Yes, it's realclimate.org. I would like your take on the science there.

Secondly, as to the non-linear kind of phenomenon you are focusing on, there are a several problems there, too. Most importantly, the effects you decribe occur on a LOCAL level. In aggregate, in describing the global effect of what's going on, the effect would come on gradually, not suddenly, since the effective area of the Earth that was effected would change gradually.


That would depend on what a particular trigger was. If you're talking about permafrost methane, perhaps. If you're talking about ocean deagasing, perhaps not. In addition, if a local phenomenon were particularly large, and atmospheric circulation could spread it hemispherically rapidly (say, in weeks to months), it would be more than local. I am not positing any particular factor here. I am simply saying that this kind of problem is not necessarily local in a complex system like the Earth's atmosphere.

By way of example, it's not like there's some all-important region of permafrost in Siberia that, after reaching the critical temperature for the requisite amount of time, would suddenly release all of it's methane into the air, over the entire region, with the effect being a sudden change in the temperature history of the globe as a whole.


Anyone making that claim has several hurdles to cross, and I have not read of any that have succeeded yet. They'd have to identify the reservoir, its extent, its trigger, and the proximity of that trigger rigorously enough to withstand scrutiny from any scientist who wanted to go out into the field to verify the data. Which is why you don't see the scientific AGW community behind such a scenario. You don't see it scoffing at it either, because, as you know, absence of evidence is not evidence of absence.

So when we consider THAT, any kind of talk about "tipping points" should be treated with extreme skepticism.

I think it should be recognized that skepticism is the default position of the scientific community.

Residence time of CO2 and most other GHGs in the atmosphere is decades to centuries. Residence time of H20 is weeks, except possibly in the stratosphere, where most H20 has anthropogenic sources. No particular element is panic worthy. But it is always easier to act on a system when your lever arm is long. I don't think we're in danger of being plunged into a pot of boiling water tomorrow, but I do think we are in danger of being the frog in the slowly heating pot of water.

re: #1351 Coracle

I consider the arctic Ice a symptom (with its own local ecological reverberations) rather than the disease.

Considering that the Acrtic ice cap was apparently in far worse shape 40 years ago, and the normal cylces of activity up there are far from well known, you really shouldn't consider what's going on there right now (which isn't much) as a "symptom" of anything. At least not a symptom of anything anybody could reasonably identify.

Maybe in 50 years, someone will be able to look back and say "Look! Thus-and-so was happening back then, which we now know would foretell such-and-such." But the study of the Arctic ice cap is still in its infancy, and anyone would be fooling themselves in claiming to have insight into it.

As I have pointed out before, does anyone even know where this year's minimum will end up? NO! I expect there may be some educated guesses out there, and if there's enough of them, and they vary enough, than at least one will end up close - but even that doesn't mean that the closest guy knows what he's talking about. You can send out 1024 unique picks for 10 NFL games (vs. the spread) on a given week, and guess what? One will be right!

When someone starts to accumulate a lengthy history of making reasonably detailed predictions as to what will happen up there that turn out to be reasonably accurate, then we can start to pay attention to talk about what it means when various things go on in the Arctic.

Anything less would be unscientific.


As to the "ecological reverberations" we, again, do not really know what's normal up there. That being said, let's keep in mind that the land in the arctic is a barren wasteland with relatively little life. It hardly seems worth all the hype about it. And if you're thinking about polar bears, the historical record shows they've gotten by through a lot worse, and exist now in record numbers. It's not rational to fret about them.

As to the melodramatic "frog in the slowly heating pot of water" meme, anyone who buys into that might want to check out the following article, and sleep better at night (if you're not hooked on the notion of patting yourself on the back for virtuously NOT sleeping well at night due to the "dire" state of Mother Earth, that is):

[Link: www.aynrand.org...]

Personally, I my assessment is that if the sound reasoning of this article (which does not take, or suggest, a stand on AGW, BTW) were widely adopted, that even the supposedly purely technical "climate change" conversation would suddenly change dramatically, as if by magic.

Since I have amply demonstrated that I am not an alarmist, I have neither the need nor desire to defend potentially faulty models they may use. ...

I didn't call you, specifically, an "alarmist" - I referred to the models that alarmists tout. That being said, you have consistently promoted and defended only the alarmist claims, and so if you are not an "alarmist", yourself, there isn't a heck of a lot of difference between you and someone who is one.

... It is also quite clear that models in general can be quite useful when their limitations and caveats are taken into account. ...

That's a truism, but the "limitations" of the models in this debate are rarely taken into account, and I've never heard any "caveats" stated. Said limitations appear to render these particular models useless, since they do a lousy job of foretelling global climate.

...My question to you is, is there any global climate model you would trust on any level?...

Of course! I'm a modeller by nature, myself, and have developed models as part of my job (although not as much as I would have liked). At one point, I found myself developing a model that would calculate the temperature of the ground, given a large number of parameters. I realized I had to stop, however, because it was clear that such a model would not be accepted because it would require hundreds of thousands of dollars to validate, and that wasn't going to happen. I guess the military is a lot pickier than the general public with its models. The public might spend trillions based on the output of models that have seen no such validation.

As I said in my last post, "When someone starts to accumulate a lengthy history of making reasonably detailed predictions as to what will happen ... that turn out to be reasonably accurate, then we can start to pay attention to talk about what it means when various things go on..."

That would depend on what a particular trigger was. If you're talking about permafrost methane, perhaps. If you're talking about ocean deagasing, perhaps not.

I am not positing any particular factor here. I am simply saying that this kind of problem is not necessarily local in a complex system like the Earth's atmosphere.

The point (again) is that the dominant effect being talked about IS the one that includes ocean degassing. Further, it seems unreasonable that "permafrost methane", for example, could possibly contribute a "hill of beans" vs the global climate. The Earth is a pretty big place. And it's even more unreasonable to expect such an effect (IF it were significant) to happen all at once - that would take coordination among the various geographic regions experiencing it.

Anyone making that claim has several hurdles to cross, and I have not read of any that have succeeded yet. ...

Then why do you seriously entertain ideas that would require such things in order to come true?

I think it should be recognized that skepticism is the default position of the scientific community.

This is a loaded statement, given the AGW context.

I think it's entirely unclear as to the proper characterization of what the scientific community really thinks about AGW. I have the impression that it's accepted in many circles in the same way urban legends get thrown around, but that when scientists in related fields actually find themselves actually starting to look at it seriously and objectively, their tune changes quickly. But I could be wrong.

re: #1350 Coracle

I'd like you to do me a particular favor. Take a look at the data in this link. Yes, it's realclimate.org. I would like your take on the science there.

I guess you realize that realclimate.org is by and for some of the most prominent and extreme AGW alarmist zealots, but you've been so civilized I decided to have a look.

One positive thing I can say is that at least it's devoid of heart-tugging stories of isolated cases of attractive critters having various habitat issues, or the usual "xyz" horror story (while simultaneously admitting that the stated scenario isn't likely - even in THEIR estimation).

That being said, it seems to have the same flavor I've seen in other posts on this thread. It starts off by admitting the point it's supposedly going to de-bunk, and then it vears off course - discussing basic physical principles (so that they sound like they know what they're talking about, to the general public) without really addressing the real point at all.

In this case, they admit that water vapor is an "important" GHG, but then wander off to a discussion about whether it is "feedback or forcing," which is besides the point (but the author stakes his argument on this, while claiming special knowledge of the all-important difference). Thank goodness we have the great wizard Gavin Schmidt to explain to us the difference! [sarc, of course]

Then we have a dissertation on the "basics" (as spun by Schmidt). To give you an idea about how legit THAT is, look at his claim that 100% of longwave (LW) radiation is absorbed by the atmosphere (the forst line of his table). First of all, to limit the discussion to longwave is taking us off track (to Schmidt's advantage - this is another trademark of "spin").

Second, LW is NOT 100% absorbed by the atmosphere. If it were, there certainly wouldn't be any point to putting LW sensors on aircraft, and that has certainly been done. You can play all kinds of games with the number-crunching that follows, and since he has already done a fair amount of that - just by limiting the discussion to "LW" (and he doesn't even define, exactly what waveband he's talking about - yet another sign that "spin" is going on) - there is no reason to expect the numbers given are meaningful.

I could also add that the spectrum of the thermal radiation given off from the Earth is not uniform, so what function you use for that is also relevant (notice that he doesn't tell us what he used).

His result that CO2 is around 25% of the GHG absorption is not credible. CO2 has very specific absorption wavebands, and these bands are few in number, and not very wide. If you find a plot of the spectral absorption of CO2 vs that of H2O and the atmosphere as a whole, what you see is that the curves for H20 and the atmosphere are almost identical, except for a waveband between about 4.1 to 4.5 microns (whereas IR goes from 1.0 micron, out to 14 microns and even beyond). See
[Link: books.google.com...]

So you've been "had". He even fails to mention that only a small fraction of atmospheric CO2 is estimated to be caused by people.

1355 Optimizer  Fri, Aug 14, 2009 10:00:36pm

[continued]

He goes on to claim that CO2 stays in the atmosphere orders of magnitude longer than H2O. That may or may not be true (I certainly wouldn't take HIS word for it), but it's besides the point, anyway.

Then he finally touches upon the "positive feedback" that I have mentioned, calling it "water vapour feedback" (maybe he's realized that if you call it "positive feedback", control theory types would instantly recognize that as unstable, which instantly raises questions as to its validity). I thought his quote, "It’s important to point out that this is a result of the models, not a built-in assumption" provided special insight into how these guys think - he talks as though the models are reality, which exist separately from "built-in assumptions." Wow.

He cites a paper as evidence that increased temperature increases water vapor, but the discussion is sort of incoherent, and ignores other studies that show the opposite. The thing is, more water vapor = more clouds, which tends to reflect the incoming solar insolation (which is a cooling effect).

One paper that shows the opposite is [Link: www.leif.org...] but that's just by a climate scientist at MIT, so he's obviously just an anti-science, Creationist, right-wing shill. [sarc] Interestingly, he mentions something about the feedback being "mostly from shortwave radiation while the feedback in the models is mostly from longwave radiation." Gee, that makes me feel observant!

Another interesting quote, given the context of this discussion, is (from the intro) "Simple calculations as well as global climate model results suggest response times on the order of decades for positive feedbacks and years or less for negative feedbacks." In other words, the things that act in opposition to CO2 warming happen much more quickly than CO2 warming.

re: #1354 Optimizer

Considering that the Acrtic ice cap was apparently in far worse shape 40 years ago, and the normal cylces of activity up there are far from well known, you really shouldn't consider what's going on there right now (which isn't much) as a "symptom" of anything. At least not a symptom of anything anybody could reasonably identify.


You have said this a number of times in this thread. I have mentioned before that images of any single point mean little, given that the area of concern is millions of square km. It is well recognized that ocean currents also affect the extentand locations of melting and nsidc and other places fold that into their sea ice predictions.

In 50 years, we'll certainly have better insight and better models. Current educated guesses are pretty good, but no one has claimed perfection. Your random NFL guess analogy is not proper for a monte carlo model. How many of thse 1024 guesses will be wrong if you fold in the individual statistics of pass connection, rushing yardage, and defensive turnovers for each team in the league? How about if you add to your model more statistics based on coaching strategies and home field advantage? Some of those will improve predictions, and some won't. You refine the model as you gather more data and end up with something that gives you a certain confidence level. No one who uses models - monte carlo or therwise - responsibly will tell you they are infallible, nor will they be caught unaware of their models weaknesses and confidence levels. Any alarmist or denier who says "models say X will happen" is, at the start, wrong.

I'm going through that paper from rand.org. On the one hand, it's interesting. On the other, it focuses soloely on policy rather than science, and is based on certain assumptions about the science. I'm not an economist or industrialist, so I doubt I'll be able to say much about that. On the other hand predictions of what "government interference" in the market will do are based on what? Past experiences may be poor predictos as technology radically changes the shape of the markes and industries. What then? Models? Are economic models any more reliable than climate models?

Then there is this:

By distorting the free market price signals individuals use to guide their choices, these and myriad other government interventions and regulations, going back decades, have lured people into floodplains and produced a higher overall vulnerability to hurricanes and flooding.


Having lived in the midwest in the 90's I know this is demonstrably false for many locations in the country. It is precisely "free market" interests, not government meddling, that drove pressure to declare leveed parts of the Missouri river bottomlands as "no longer floodplains" and zone them for businesses and residences. The same forces - market and profit driven - build housing complexes and infrastructure on barrier islands and shoreline communities ocean coasts.

The article's apparent faith in the free market's ability to power our way out of any climate change may be well founded - for the industrialized first world. Since it's aynrand, I'm guessing it consideres the rest of the world less important. But that may just be my preconception. I will read and see.

More later.

re: #1353 Optimizer

Since I have amply demonstrated that I am not an alarmist, I have neither the need nor desire to defend potentially faulty models they may use. ...


I didn't call you, specifically, an "alarmist" - I referred to the models that alarmists tout. That being said, you have consistently promoted and defended only the alarmist claims, and so if you are not an "alarmist", yourself, there isn't a heck of a lot of difference between you and someone who is one.


I have defended Anthropogenic CO2 and GHG (AGHG?) as the primary cause of post industrial revolution baseline GW. I believe the evidence for that is pretty incontrovertible. I also believe that evidence shows AGHG and thus GW will continue to increase for the foreseeable future. Further, there will be impacts - ecological and economic. Where my jury is out is on exactly what those impacts will be, their intensity, and what segments of the entire system they will affect. If you consider that alarmist, then we cannot proceed productively beyond this point.

I'm a modeller by nature, myself, and have developed models as part of my job (although not as much as I would have liked).


I also at times use models professionally. I waould assume you are aware that in many complex systems multiple models can exist and compete with one another. And that some are very good at predicting certain aspects or segments of a system while failing at others.

I think it should be recognized that skepticism is the default position of the scientific community.


This is a loaded statement, given the AGW context.


It's where a scientist must start. It is where I started. I came to the conclusions I have - and retain the questions I have - based not on any doctrine or dogma, but by reading and assessing. You seem to be making the argument that the vast majority of scientists do not, in fact, behave this way. I think that is wrong.

1359 Coracle  Sat, Aug 15, 2009 10:02:31am

re: #1354 Optimizer

It starts off by admitting the point it's supposedly going to de-bunk, and then it vears off course - discussing basic physical principles (so that they sound like they know what they're talking about, to the general public) without really addressing the real point at all.


I think you're missing the point here. And that is that the contention "H20 is the biggest greenhouse gas" while true, is irrelevant to the effects of AGW. All the rest is an explanation as to why, aimed at a lower level of scintific education than yours. No special knowledge is claimed - nothing that anyone can't also pick up with further reading.

To give you an idea about how legit THAT is, look at his claim that 100% of longwave (LW) radiation is absorbed by the atmosphere (the forst line of his table).


I think you're misreading the function of the table. The preceding paragraph states:

Long-wave (or thermal) radiation is emitted from the surface of the planet and is largely absorbed in the atmosphere.


"Largely". Not completely. In the table used for the simple model, the "Fraction LW obsorbed" is of total LW absorbed, not "of total LW". Further, this table is used not to illustrate total absorption of the atmosphere, but to show relative importance of individual absorbers in the mix.

I'm not sure why a focus long-wave, i.e. thermal radiation is off track. The trapping of long-wave is the principle component of greenhouse warming, natural or not.

I could also add that the spectrum of the thermal radiation given off from the Earth is not uniform, so what function you use for that is also relevant (notice that he doesn't tell us what he used).


Your parenthetical statement is incorrect. The source is pretty clearly listed - and linked to. You can downlaod the code yourself, examine the model and functions, and run whatever scenarios you like. Codes like this are used not just for climate modeling, but to calculate atmspheric extinction for astronomical spectroscopy (which contains independent verification from numerous on-ground and in-space observatories). Atmospheric models are pretty darn refined by this point.

His result that CO2 is around 25% of the GHG absorption is not credible. CO2 has very specific absorption wavebands, and these bands are few in number, and not very wide.


Band size and quantity is not the telling factor here. Band efficency is. CO2, in its absorption bands, on a molecule by molecule basis, is more efficient an absorber than H2O in the wavelengths emitted by the Earth. The earth emits as a blackbody of approximately 255K, peaking a bit above 10 microns, near a CO2 absorption - and not an H2O absorption - maximum.

So you've been "had". He even fails to mention that only a small fraction of atmospheric CO2 is estimated to be caused by people.


You seem to think Schmiidt is the only voice I've ever listened to. There are independent sources that show the industrial-age increase in CO2 is anthropogenic. Of the current ~380 ppmv, about about 100ppmv is anthropogenic. I don't consider a 35% increase a small fraction.

Please don't take any one person's word for it. I don't.

I don't think we're going to see eye to eye on the issue of feedback mechanisms in a forum such as this. I think it could be done, but it would require more time and patience than either of us have.

He cites a paper as evidence that increased temperature increases water vapor, but the discussion is sort of incoherent, and ignores other studies that show the opposite. The thing is, more water vapor = more clouds, which tends to reflect the incoming solar insolation (which is a cooling effect).

One paper that shows the opposite is [Link]

It is easy to dismiss a discussion you disagree with as incoherent without citing specifics, but that doesn't make it so. It would also be a neat trick for a webpage to respond to a paper that hasn't actually been published yet. The version you link to is weeks old, and the acceptance date is July 20. On the other hand , Lindzen's methods are as subject to scrutiny as any other scientist's so we'll see how it unfolds. Got any others?

Another interesting quote, given the context of this discussion, is (from the intro) "Simple calculations as well as global climate model results suggest response times on the order of decades for positive feedbacks and years or less for negative feedbacks." In other words, the things that act in opposition to CO2 warming happen much more quickly than CO2 warming.

What that implies is that year-term mechanisms cannot be responsible for decadal effects. If the negative forcing of H2O were dominant, there would be no appreciable change at all beyond regional climate fluctuations such as ENSO. That's not the case.

You missed the point my NFL analogy. Those guesses were not random, they simply enumerated all possible outcomes, making a 100% probability that exactly one of them would be 100% correct.

Not at all. It is quite possible that there was a major retreat. It is also possible that there was a local current variation near Greenland that drove ice cover in that part of the arctic without affecting total arctic summer ice significantly. Absent the imaging and recording infrastructure we have now, we cannot say either way.

Current "educate guesses" have been unable to predict anything with any accuracy at all, and are being shown to have serious flaws in their main compnents. So they're hardly "pretty good".

Oh, I got the point. With 1024 different guesses of 1024 possible outcomes, guided by nothing, one is guaranteed to be right. That assumes that the guesses have no predictive basis at all. However, that's not the way modeling works, and I think you know that. Models of the physical world are based on physical principles, and those that produce inaccurate results are discarded or refined. The net result is models that survive become more accurate over time. GCMs, for example, have come a huge way since they began decades ago, and they have a huge way to go yet.

That tends to assume that everyone knows the facts of floodplain hydrology and river and coastal proceses, which most people don't. I know, part of the Randian philosophy is that it is the individual responsibility to know the risks of what you do. I'm a big, big fan of personal responsibility, but not everyone has the same level of education and ability to assess all the risk factors they encounter in their lives.

If a builder pressures the govt to zone in a certain way, and force rules on insurance companies, that's not the "free market" at work.

It really too close to the center of the ice pack for that theory to be reasonable, but I let the alarmists off too easy on this one for another reason. They'll point to something like this, and call it an "isolated case", but then they'll look at ... oh ... I dunno ... maybe a stretch of drought in CA, say, and cry, "See! Proof! AGW!!!"

That's far too general a statement for me to attempt to rebut.

Now that's just evasive, but let's make it easy for you. Is there a climate model or model regarding Arctic (or even Antarctic) ice, be it in the sea, or on the land, with any kind of record of having accurately predicted anything? If so, then let's look at a prediction they're making for, say, three years from now, and see how they do.

I'll bet if they launched a space probe to Jupiter, and predicted where it should be three years from now, that you could bet your house that it'd turn out to be pretty close to dead-on. With global climate? Heck - that's just a joke!

... Models of the physical world are based on physical principles, and those that produce inaccurate results are discarded or refined. The net result is models that survive become more accurate over time. GCMs, for example, have come a huge way since they began decades ago, and they have a huge way to go yet.


Ideally - and over large time scales - that's great, but when Galileo and Copernicus figured out that the Earth went around the Sun, powerful political interests put up a huge stink, and the vast majority of scientists fell in line. I have personally seen models that lauded as far better than they are, and it always comes down to financial interest. Suddenly intelligent, educated people start believing nonsense when that promotion or raise looks more likely by buying into the dogma. It not even a conscious process.

Yeah, they "have a huge way to go!" That's why we shouldn't cripple our economy based on what they tell us!! Especially when common sense tell us otherwise,and the proponents have been shown to be dishonest.

What's to stop him?

Another excellent example of popular ignorance about economics. As soon as the govt steps in, the market is no longer "free". The question as to whether a businessperson is free to do this is irrelevant. The businessperson is not the market. When Madoff screws his investors, it's not "capitalism" or "the free market" because he's a businessman trying to make money - it's called "fraud".

And they have the same technical capabilites and resources as the current first world?

Again, popular ignorance at work. You don't have the "technical capability" to make a cell phone, but maybe you have one, right? You don't have the "resources" to drill a 5000 foot hole in the ground, but you probably have a car that relies on the fact that someone else does.

The difference between the "haves" and "have nots" is the degree of economic freedon that their form of govt allows. You know, the Indian economy took off when they figured out that having foriegn countries invest there wasn't "having their natural resources exploited by the industrialized world". China's took off when they started embracing some capitalism. Singapore has no natural resources to speak of, or "technical capabilities", but has one of the highest per capita GDP in the world.

I'm being evasive? Your claim was:

Current "educate guesses" have been unable to predict anything with any accuracy at all, and are being shown to have serious flaws in their main compnents.


From what I read, PIPS forecasts are reasonably good on the seasonal scale. And These guys seem to do pretty well month to month agglomerating and comparing a variety of models.

I'll bet if they launched a space probe to Jupiter, and predicted where it should be three years from now, that you could bet your house that it'd turn out to be pretty close to dead-on. With global climate? Heck - that's just a joke!


This is clearly an aside, but that is wrong. In the 5+ years it took Galileo to get to Jupiter it required over 20 trajectory correction maneuvers. Any 3 years with no adjustments calculated carefully from monitoring the spacecraft actual trajectory and the mission would have failed. Sure, we would have known about where it was. But that wouldn't have been sufficient.

Ideally - and over large time scales - that's great, but when Galileo and Copernicus figured out that the Earth went around the Sun, powerful political interests put up a huge stink, and the vast majority of scientists fell in line.


That works either way. There are political interests on both sides of AGW that fail to pay attention to the science.

Yeah, they "have a huge way to go!" That's why we shouldn't cripple our economy based on what they tell us!! Especially when common sense tell us otherwise,and the proponents have been shown to be dishonest.


I never advocated crippling our economy. Frankly, I think proactive industrial reapplication to alternative energy would strengthen our economy considerably.
I don't know what your common sense is telling you, but it's not telling "us" anything so simple.
"The proponents have been shown to be dishonest." is a sweeping generalization that is inherently inaccurate.

The difference between the "haves" and "have nots" is the degree of economic freedon that their form of govt allows.


I recognize the philosophy. I don't agree with it.
