GOP presidential candidate Newt Gingrich, who once thought climate change was man-made and required action, has changed his position. He now denies the scientific consensus.
"Republican presidential candidate Newt Gingrich on Wednesday said it's unclear whether man-made global warming is real.
'I believe we don't know,' he told Fox News' Sean Hannity in a Wednesday night interview.
In 2008 Gingrich appeared in an ad with then-House Speaker Nancy Pelosi urging action on climate change. 'We do agree that our country must take action to address climate change,' he said, sitting on a sofa with Pelosi in front of the U.S. Capitol. The former House speaker recently said that the ad was 'the dumbest thing I've done in recent years.'
Earlier in his career, Gingrich co-sponsored a 1989 bill stating that climate change was 'resulting from human activities.'"
