In New Hampshire today, Texas Governor Rick Perry told a crowd that he believed global warming was “a scientific theory that has not been proven and, from my perspective, is more and more being put into question.”

That’s one more contrast between Perry and GOP rival Mitt Romney who said in June, “I believe the world is getting warmer, and I believe that humans have contributed to that . . it’s important for us to reduce our emissions of pollutants and greenhouse gases that may be significant contributors.”
