PALIN’S GLOBAL-WARMING SKEPTICISM…. Since Sarah Palin was added to the Republican ticket, there have been multiple reports about her skepticism regarding the science behind global warming. Last night, during her ABC interview, Palin was pressed on her beliefs, and got a little defensive.

“Show me where I have ever said that there’s absolute proof that nothing that man has ever conducted or engaged in has had any effect or no effect on climate change. I have not said that,” Palin told Charlie Gibson.

Well, what has she said? The AP takes a closer look, and concludes Palin’s remarks to ABC are “at odds with her previous statements.”

[I]n the past Palin has said she does not believe global warming is caused by human activity. She has told the Internet news site Newsmax, “A changing environment will affect Alaska more than any other state, because of our location…. I’m not one, though, who would attribute it to being man-made.”

In an interview with a Fairbanks newspaper within the last year, Palin said: “I’m not an Al Gore, doom-and-gloom environmentalist blaming the changes in our climate on human activity.” ABC cited the interview as being at odds with her statement.

I can appreciate Palin being embarrassed about her beliefs now; she’s obviously well outside the scientific mainstream. If I were her, in my first national television interview, I’d be tempted to distance myself from right-wing talking points, too.

But Palin’s record is Palin’s record, and the fact remains that she’s so far out there, she’s rejected the connection between global warming and human activity. Indeed, she’s done so more than once. This not only tells us something important about Palin’s understanding of public policy, it also tells us a great deal about how she perceives and considers evidence that runs counter to her ideology.
