On this issue - Global Warming - I am quite interested, but not overly convinced of the "imminence of disaster".
If you look at a fairly long-term chart of global climate changes (say, several hundred thousand years), then the projected "disastrous" changes for the next 50 to 100 years barely are discernable when viewed against the truly large climate swings that apparently have cycled over and over on our planet. Now changes of THAT magnitude would be disastrous for the infrastructure of our current civilization... but this old Earth has seen them many times.

If CO2 is the determinant factor that you are concerned about... then remember that counter-cyclical effects will (presumably) also occur. Heightened levels of plant growth - algae in the oceans and terrestrial plants - is likely to act as "carbon sinks" to countervail against the rising levels of CO2 in the atmosphere... and feed more of the 'teeming billions' in the process.

Higher temperatures are also likely to increase water vapor in the atmosphere: more cloud cover tends to increase the albedo (the reflectivity) of the Earth, and thus reflect more solar radiation back into space, also serving to cool the planet.

Of course, with even small climate changes, there will be winners and losers. Siberia and most of Canada could use a bit of warming (if you ask the human inhabitants). It's the inner-Continental areas that could get a bit warm... and desertification is a serious issue. Low-lying Micronesian type islands are also not looking like good long term investments... but there is LOTS and LOTS of land in Siberia and some other frozen wonderlands.
