Sunday is Earth Day, and some Republicans who aren't convinced of climate change may not be celebrating. Mitt Romney's views on the matter have evolved to "we don't know what's causing climate change," while Sen. James Inhofe (R-OK), the ranking member on the Senate Committee on Environment and Public Works, has used the Bible to deny global warming.
Here is what the GOP presidential candidates and others have to say about climate change.
Speaking at the Pittsburgh Consol Energy Center in October, Romney expressed doubts that climate change is caused by humans. "My view is that we don't know what's causing climate change on this planet," he said
, "And the idea of spending trillions and trillions of dollars to try to reduce CO2 emissions is not the right course for us."
Previously, the former governor had expressed markedly different views on the issue. At a June town hall
, he said, "I believe the world's getting warmer...I believe that humans contribute 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. And so I think it's important for us to reduce our emissions of pollutants and greenhouse gases..."
A larger opposition file
from 2008 documents larger flip-flops from Romney on the issue of climate change. According to a Politico report, it also appears that some green backers of the Romney campaign are banking on him returning to the center
on environmental issues either during the general, or if he gets elected president.
