In her second interview with Charlie Gibson, the Alaska governor says humans may play a role in climate change– a different view from what she’s suggested in past comments.
Also says she continues to disagree with McCain about drilling in ANWR, which he opposes and she supports.
“We’ll agree to disagree but I’m going to keep pushing that and I think eventually we’re all going to come together on that one.”
More clips of Gibson’s interviews from Alaska will be aired on Friday’s “World News” and in a “20/20″ special.
