evidence: Wrapping himself unabashedly in the mantle of climate science denial, Environmental Protection Agency Administrator Scott Pruitt declared on Thursday that he does not believe carbon dioxide is a primary contributor to global warming. [...] "I think that measuring with precision human activity on the climate is something very challenging to do and there’s tremendous disagreement about the degree of impact," Pruitt answered. "So no, I would not agree that it’s a primary contributor to the global warming that we see." Pruitt added, "We need to continue the debate and continue the review and the analysis." [...] "There is no doubt whatsoever that the planet is warming and it is primarily due to increased carbon dioxide in the atmosphere from burning of fossil fuels," he said. "Carbon dioxide is a greenhouse gas and we can demonstrate clearly that the observed warming of the planet would not have occurred without that change in atmospheric composition. These are scientific facts, not opinion, and it is incumbent on politicians to take account of the scientific evidence."
