From the Gibson interview:
GIBSON: But I, color me a cynic, but I hear a little bit of change in your policy there. When you say, yes, now you're beginning to say it is man-made. It sounds to me like you're adapting your position to Sen. McCain's.
PALIN: I think you are a cynic because 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 affect, or no affect, on climate change.
Here is what she said a year ago:
"I'm not a doom and gloom environmentalist like Al Gore blaming the changes in our climate on human activity."
Charlie Gibson is not a cynic. Sarah Palin is a liar.
