This just came through on Digg, so I thought I'd make a note here of my comment.

I note also that people have been trying to bury my comment, even though it is pretty damn accurate and simply asks questions.

My comment:

What nonsense. And this a day after that stupid article comparing evolution and AGW "deniers". So let's discuss evolution:

"The polar bear probably first appeared roughly 200,000 years ago, during the Pleistocene."
"Scientists believe that the polar bear evolved from a group of brown bears that became isolated by glaciers in an area near Siberia. The stranded bears underwent a rapid series of evolutionary changes in order to survive on the ice."

A few things:
1 - How many times has the temperature risen 2oC above what it is today in the last 200,000 years? Answer, probably 2 or 3. Did the polar bear die out? (e.g. http://en.wikipedia.org/wiki/Holocene_Climatic_Opt ...
2 - The evolution of the bear was a result of rapidly changing climate. But what about the brown bear? Did it die out?
3 - It should also be noted that there are more polar bears on the planet today than there were 40 years ago. The majority of deaths - by an order of magnitude - is a result of humans literally killing them, for sport or food or preservation.
