For a guy with a nasty reputation as a flip-flopper, he isn’t doing himself any favors.

QUESTIONER: Will you continue to support the EPA’s air quality standards that will protect all Americans from the burning of coal?

ROMNEY: I believe we should keep our air and our water clean. And that we don’t want to have pollutants that are interfering with our health and damaging the ability of our children to enjoy good health. So no question we have to have standards that improve the quality of our air. And I support reasonable standards. . . . Do I support the EPA? In much of its mission yes, but in some of its mission no. The EPA getting into carbon footprints, and . . . [APPLAUSE] I think we may have made a mistake, we have made a mistake is what I believe, in saying that the EPA should regulate carbon emissions. I don’t think that was the intent of the original legislation, and I don’t think carbon is a pollutant in the sense of harming our bodies. We can agree to disagree. . . My view is that the EPA getting into carbon and regulating carbon has gone beyond the original intent of the legislation. I do believe we should reduce the pollutants that harm our health.

Mitt had this to say on June 3rd:

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. And number two, 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. And so I think it’s important for us to reduce our emissions of pollutants and greenhouse gases that may well be significant contributors to the climate change and the global warming that you’re seeing.
