I'm sure that global warming believers will think it is unfair for their theory to be considered alongside the other ones (rapture, Mayan calendar). Of course, Rapture believers (are there any of them on these boards?) would undoubtedly think the same thing. It's unfair to compare their theory, which is the Word of God, to other hedonistic ideas like the devil-worshipping Mayans or those man-worshipping scientists. And many Mayan calendar believers (many of whom are still convinced that something may happen sometime soon...) don't care for other theories that are created as a result of organized religion or of current scientific thinking that is not up the same standards as the Ancient Mayans.
The fact is, all three theories are equally misguided. There are wrong predictions from all three camps and I think the only fair thing to do when one makes such claims is to call them out on it. Regardless of whether someone uses the Bible or a hockey stick graph to show why we're all doomed, they should be treated the same.
I look forward to discussing AGW with Brian more deeply. In the meantime, I wanted to comment specifically on the Muller video. It is interesting because he is a skeptic-turned-believer on AGW. A bit more recently, James Lovelock, was a believer-turned-skeptic on the exact same issue. I wrote a blog entry about it here:
When the piece was picked up by WattsUpWithThat, their audience was quick to point out that Muller was never really a skeptic. He was always a believer, had a brief change of heart when the ClimateGate emails broke out, and then went right back to believing again.
In particular, one of the commenters quoted Muller from 2004: “If you are concerned about global warming (as I am) and think that human-created carbon dioxide may contribute (as I do)...”
I would have to think that in thousands of years' time, societies are going to look back at those of us in the 20th/21st centuries as utter fools for believing in AGW.
