He said it was a “mistake”. As far as I know, correct me if I’m wrong, he never said why or offered any elaboration or disavowed that he believed in climate change.

Why appear in the ad if he didn’t believe the nonsense and favor a Gore/Pelosi style radical government solution to the imaginary problem? Doesn’t make any sense.

Maybe now he has seen the new data and has been convinced.

He appeared in the ad's, thinking the problem was a real one, to say that even though they agreed there was a problem, they disagreed on how to deal with it.

Newt wanted to take a free market approach to it.

RE :”He said it was a “mistake”. As far as I know, correct me if I’m wrong, he never said why or offered any elaboration or disavowed that he believed in climate change.”

Simple :
1) He says its a mistake for the same reason Romney became ‘pro-life’, to make it through the primary
2) He is no longer being paid by the ethanol industry so he gets nothing for pushing it now.
