GOP Science Chair Ralph Hall On Climate Change: ‘I’m Really More Fearful Of Freezing, And I Don’t Have Any Science To Prove That’ | Rep. Ralph Hall (R-TX), the chairman of the House Science and Technology Committee, is one of the most radical global warming deniers in the U.S. Congress. In interview with National Journal’s Coral Davenport, Hall accused climate scientists of a conspiracy to concoct evidence that the planet is changing because of the hundreds of billions of tons of greenhouse pollution from burning fossil fuels. “I’m really more fearful of freezing. And I don’t have any science to prove that. But we have a lot of science that tells us they’re not basing it on real scientific facts,” Hall said.
