I was able to conduct interviews with former IPCC authors Mike Mann and Stefan Rahmstorf last month, just after the most recent report summary was released. Good basic intro for anyone that needs to be briefed quickly.
This idea that I saw tweeted by David Brin seems like the sanest approach to geo engineering to overcome AGW yet.

Two other comments I anticipate I’ll get:
1) “You didn’t understand what [insert name here] meant.”
Yes, that’s entirely possible. In the absence of facts and figures, a feelie argument is usually vague and ambiguous, often hinting at some elusive point that’s never explained. When I read a scientific paper, on the other hand, I understand exactly what it’s saying. The hypothesis is laid out, the methodology explained, the observations and calculations clearly shown, and the conclusion spelled out. That’s the difference.
2) “The idea that CO2 is a trace gas is not a ‘feeling’. It can be shown that it has no effect on climate.” My response: Yes, but the ‘feeling’ is that because CO2 is a trace gas then it follows that it has no effect on climate. If this is correct, please cite a study that has some facts and figures to support it, otherwise it remains just a ‘feeling.’ If you have a source with some other evidence that CO2 has no effect on climate, then I have probably covered it in a previous video.
New research places tighter constraints on when contiguous permafrost begins to melt in large amounts. The news is grim.

Videographer Peter Sinclair captures the views of eight scientists representing some of the nation’s leading research institutions in a concise video newly produced for The Yale Forum.
And in the “regardless of what happens in the Middle East, humanity is screwed” department…
A report by the UN says global attempts to curb emissions of CO2 are falling well short of what is needed to stem dangerous climate change.
The UN’s Environment Programme says greenhouse gases are 14% above where they need to be in 2020 for temperature rises this century to remain below 2C.
The authors say this target is still technically achievable.
But the opportunity is likely to be lost without swift action by governments, they argue.
The UNEP report follows on from a new analysis by the World Meteorological Organisation that says the amount of greenhouse gases in the atmosphere reached a record high in 2011. It suggests that CO2 has now reached concentrations of 390.9 parts per million, or 140% of the pre-industrial levels of 280ppm.
The impact of these gases has been significant, says the WMO, causing a 30% increase of the warming effect on the climate between 1990 and 2011.
In 2010 (the latest year for which we had data) New York City added 54 million metric tons of carbon dioxide (equivalent) to the atmosphere, but that number means little to most people because few of us have a sense of scale for atmospheric pollution.
Carbon Visuals (carbonvisuals.com) and the Environmental Defense Fund wanted to make those emissions feel a bit more real - the total emissions and the rate of emission. Designed to engage the ‘person on the street’, this version is exploratory and still work in progress.
NYC carbon footprint:
54,349,650 million tons a year = 148,903 tons a day = 6,204 tons an hour = 1.72 tons a second
At standard pressure and 59 °F a metric ton of carbon dioxide gas would fill a sphere 33 feet across (density of CO₂ = 1.87 kg/m³: bit.ly). If this is how New York’s emissions actually emerged we would see one of these spheres emerge every 0.58 seconds.
Emissions in 2010 were 12% less than 2005 emissions. The City of New York is on track to reduce emissions by 30% by 2017 - an ambitious target.
