Hey All,
One more comment.
In my opinion the issue with climate change discussions is the failure to consider the real issue - which is simply what are and how serious are the consequences? If the consequences are serious then it makes sense not to contribute to climate change in order to buy time to adapt - assuming a contribution significantly speeds climate change. The way I see it the CO2 mechanism for climate change really rests on two pieces of evidence - chemistry and physics which long ago demonstrated that the "greenhouse gas" effect is real and the apparent fact that at least once once in geologic history climate changed due to a mass CO2 pulse into the atmosphere - see the PETM event on wiki for example. The main question in my mind is - How serious are the consequences?

Might also look at Gwynne Dyer's book climate wars.
If human society as we know it has evolved under relatively speaking "constant" climate the question becomes can humans adapt peacefully to climate change? If not we need all the time we can get to learn how to do so - especially in a world on the verge of not only having nuclear weaponry which we have but soon the wind will be the delivery mechanism for biological "warheads". If China can't produce food because of climate change - beware those downwind. No F22A raptor can stop a wind carried virus.
