Republican presidential hopeful Mitt Romney back-tracked almost entirely on his climate change stance Wednesday and said that he would do nothing to curb harmful carbon pollution.
Romney—who in the past has affirmed that he believes the climate is warming and that human activity is contributing to climate change—said in a Lebanon, New Hampshire town hall meeting that he “doesn’t know” if climate change is caused by humans and that he wouldn’t invest in curbing carbon pollution.
"Do I think the world's getting hotter? Yeah, I don't know that but I think that it is," Romney said. "I don't know if it's mostly caused by humans."
"What I'm not willing to do is spend trillions of dollars on something I don't know the answer to," he continued.
The former Governor of Massachusetts’ previous status as the front-runner for the Republican nomination has come into question since the recent entrance of climate denier Rick Perry into the race.
