That, we can agree on. I'm not skeptical about climate change; it's clear the planet is warming. The question is, how fast, why, and what should we do about it? That's where the hysterical demands of the AGW True Believers start to wear thin. Yes, ice cores and historical data support the theory that the planet is warming. However, they're not accurate to the fractional degree accuracy necessary to make meaningful predictions, or to decide what we should do about it. We may very well do the wrong thing! Just what is the average temperature of the planet? How do you measure it? The computer climate models blithely spit out conclusions based on assumed triple digit input accuracy. Computer models are great for helping to understand the behavior of a system with well defined starting conditions; they're far less useful for making meaningful predictions based on real world data. C02 is a weak greenhouse gas, far weaker than water vapor. It only makes a difference in areas that are already hot and dry. I agree that we should be leery of cutting down forests and spewing stuff into the air, but crap like "carbon trading" just makes some politicians very wealthy while raising eergy costs for the rest of us. Biofuels, solar, and wind are a drop in the bucket. The only energy sources that can make a signifficant dent in our consumption of non renewable fuels are nuclear and in the longer term, perhaps, space based solar. -Dana Duct tape is like the Force.
