I like Birdog's proof of global warming.
I read Crichton's book debunking warning and decided that I needed to make up my own mind on this issue by getting back to the basics. I started with two questions and researched the evidence for each. Are we in a global warming phase and what known factors account for global warming and cooling? Sunspot cycles, the wobble in the earths spin, the changing shape of our orbit around the sun from slight ellipse to circular define interacting long term cycles. Then volcanism, and asteroid impact randomizes the picture somewhat. Greenhouse gases follow the rise and fall and normally amplify the temperature flux.
I found the evidence of overall warming sound and that none of the so-called natural factors explain it. The factor supporting the current warming is most likely to be the extra greenhouse gases from fossil fuels we have added to our atmosphere. Personally, I have concluded that we have a enormous problem which is only compounded by misinformation.
