Global Warming Heats Up Republican Attacks On EPA : NPR

Others, including Rep. John Dingell, D-Mich., think the law is ill-suited to deal with the problem. Dingell led negotiations over the last major overhaul of the Clean Air Act, in 1990. On Wednesday, he told Jackson the agency's use of the law for global warming has put it in the "intolerable hole in which I find you."

Rep. Henry Waxman, D-Calif., the top Democrat on the committee and author of the climate legislation that passed the House in 2009, said that while Republicans could rewrite the nation's laws, they couldn't change scientific evidence showing global warming is a threat.

"The underlying premise of this bill is that climate change is a hoax," Waxman said. "The science hasn't changed in the last two years; in fact, it's only gotten stronger."
