I thought this exchange on global warming was one of the most important of the evening, not just for what each candidate said about the issue at hand, but also for what their general approach to the issue said about how they would govern.
Sarah Palin explicitly said she didn't want to discuss the causes global warming. Joe Biden, on the other hand, made the obvious -- and important -- response: if we don't understand the causes for a problem, we can't come up with a solution for it.
As he says, that lack of curiosity is the probably the biggest fundamental difference between Obama-Biden and McCain-Palin.
Here's a transcript:
PALIN: I'm not one to attribute every man -- activity of man to the changes in the climate. There is something to be said also for man's activities, but also for the cyclical temperature changes on our planet. But there are real changes going on in our climate. And I don't want to argue about the causes. What I want to argue about is, how are we going to get there to positively affect the impacts?
BIDEN: Well, I think it is manmade. I think it's clearly manmade. And, look, this probably explains the biggest fundamental difference between John McCain and Barack Obama and Sarah Palin and Joe Biden -- Gov. Palin and Joe Biden. If you don't understand what the cause is, it's virtually impossible to come up with a solution.
