Climate change deniers spout B.S., says Al Gore

(By DARREN SAMUELSOHN, POLITICO.com) - Al Gore is calling B.S. on global warming skeptics.

The former vice president and climate crusader told an Aspen Institute communications seminar Thursday that people who doubt climate science are the same ones who helped tobacco companies over four decades question the dangers of cigarette smoking.

"Some of the exact same people — by name I can go down a list of their names — are involved in this," Gore said. "And so what do they do? They pay pseudo-scientists to pretend to be scientists to put out the message: ‘This climate thing, it’s nonsense. Man-made CO2 doesn’t trap heat. It may be volcanoes.’ Bullsh—! ‘It may be sun spots.’ Bullsh—! ‘It’s not getting warmer.’ Bullsh—!”
