I am a bit of a skeptic regarding anthropogenic global warming and no fan of Al Gore. I have joked that he got the Nobel for basically making a movie staring Al Gore giving a lecture, though I realize that he has been at this for a long time. I also question the doomsayers claiming planetary doom is imminent, given that personally they are not acting as though planetary doom is imminent.
That said, good for him.
Then again, last year I was very excited about the Peace Prize going to the Grameen Bank. I know that many saw that award as controversial and undeserved.
At any rate, at least finally the world is waking up to the threat of Manbearpig.
