Republican White House hopeful Mitt Romney is trying to cement his status as a skeptic of man-made global warming after coming under fire from conservatives for saying that humans contribute to climate change.
During a fundraising event in Pittsburgh on Thursday, Romney cast doubt on climate science, bringing his position on global warming closer to that of his rivals for the GOP nomination.
“My view is that we don’t know what’s causing climate change on this planet,” Romney said during a speech, a clip of which was posted by the liberal blog Think Progress. “And the idea of spending trillions and trillions of dollars to try to reduce CO2 emissions is not the right course for us.”
EDIT
Conservatives slammed Romney after he said in June that human beings were partly responsible for climate change, bucking the position of many in his party. “I don’t speak for the scientific community, of course, but I believe the world’s getting warmer. I can’t prove that, but I believe based on what I read that the world is getting warmer,” he said in New Hampshire. “And No. 2, I believe that humans contribute to that. I don’t know how much our contribution is to that, because I know that there have been periods of greater heat and warmth in the past, but I believe we contribute to that.”
