re: #246 Obdicut

CO2 doesn’t form into layers, idiot. Various layers of the atmosphere have various concentrations, but it doesn’t form it’s own layer. It diffuses.

But even though you don’t really understand it, I’m glad you acknowledge that CO2 traps heat in atmosphere. You’ve already acknowledged that mankind has been putting out enormous amounts of CO2.

So, since CO2 traps heat in atmosphere, and since we’ve added a ton of it, we’d expect to see warming. And, lo and behold, we do.

We do? No where near as much as all the climate models predict

Now, there are four major climate models, each using entirely different software and algorithms, each of them using the wide array of temperature data sources. Each of these is highly accurate in prediction— as in, if you take the model, take the inputs, they model how our climate has behaved.

So, given that the models are accurate, the basic science is very well-established, and the facts match what we’d expect— lots of CO2 added to the atmosphere, lots of warming, concurrent with that CO2 increase.

So, good job disproving your own half-assed argument.

There is a major flaw in your reasoning - the government climate models are not accurate - they have all greatly overestimated the effect of CO2 emissions on global temperatures by roughly a factor of three. The facts as you say do not match what AGW proponents - the IPCC and especially NASA’s Hansen - have predicted. On this point we disagree, and its a major difference.

Key consideration is the dampening effect of clouds, oceans, water evaporation, etc, instead of an amplifying effect which the models utilize. Something is at work which is keeping temperature down to the roughly 0.5 degree C rise per century since the 1600’s, with short-term warming and cooling trends ever since.
