I might point out that the consensus about AGW is crumbling quicker then the ice on my driveway. Even Professor Mojib Latif, a leading member of the UN’s Intergovernmental Panel on Climate Change, has shown that at least 50 percent of the climate change is natural, and he is certainly no "denier." I happen to believe it is probably a lot more then 50 percent. However, the point is that it might be nice is we actually knew just how much effect humans have before we wreck the economies of the developed nations and impede the developing countries from actually developing with this Kyoto/Copenhagen foolishness. We can certainly be conservationists without thinking we all have to drive solar-powered roller skates. Since the climate models that you rely on to prove AGW have not been able to predict the cooling of the last decade, maybe we can wait until we have models that work better, or even better we might pay more attention to actual temperature data and not to data massaged beyond recognition by our friends at the EAU/CRU.
