Last night's episode of Bill Maher's Real Time featured evangelical atheist Richard Dawkins (the very poor man's version of Christopher Hitchens), explaining why scientists can't be certain of much of anything:

I think any scientist would be unwise to commit himself to saying there definitely is not anything. I mean, I can’t definitely commit myself to saying there are no fairies. I’m pretty sure there are no fairies. [laughter] But, I think it would be unscientific to do what the extreme religious people do and say, “I know there is a god.”

It's an interesting contrast to comments by NASA scientist James Hansen earlier this week complaining about a high school textbook that didn't portray global warming as a fact rather than a theory:

IHansen has sent Houghton Mifflin a letter stating that the book's discussion on global warming contained "a large number of clearly erroneous statements" that give students "the mistaken impression that the scientific evidence of global warming is doubtful and uncertain."

So Hansen is certain that global warming is real and the greenhouse gases are the cause. As are Bill Maher, Barack Obama, Al Gore, and every other luminary of the left. Immediately following his interview with Dawkins last night, Maher proceeded to mock Christians for their skepticism of global warming (or indifference, as he would have it), explaining it as a result of their belief in the Rapture. But hasn't the left embraced global warming as their own version of the Rapture? They do not harbor any doubt, but believe with the fervor of religious conviction that the end of civilization will come as a result of consumerism. And they seem completely unaware that in believing this, they have shed the very skepticism that is supposed to define the secular left.

Also notable from last night's show was Richard Clarke claiming of Bill Clinton, "He doesn’t make mistakes." Right.
