Kentucky Sen. Rand Paul, who has struggled to generate momentum in his bid for the Republican nomination, told the editorial board of New Hampshire’s Concord Monitor that it’s impossible to have a logical discussion on climate change in the U.S.

“I think we’re in an absurd situation,” Paul said. “I don’t think anybody in this room knows how much is nature and how much is man. What I can tell you is, if you read the general lay press, everybody’s like, ‘Oh yeah, it’s all man. It’s 99 percent man.’ They’re convinced of this. They know nothing about (it). It’s a conjecture.”

Paul said he believes some pollution controls are necessary but he opposes the President’s Clean Power Plan, regulations intended to reduce carbon emissions from power plants, because “there will be no energy from coal in our country.”
