That statement put Pruitt at odds with the agency he leads and it was widely condemned by scientists and environmental activists. The EPA's homepage cites carbon dioxide as the primary greenhouse gas contributing to climate change, a view backed by NASA and the National Oceanic and Atmospheric Administration.

They found that 48 percent of people in the U.S. believe climate change is due to human activity, 31 percent attribute it to natural causes and 20 percent say there is no evidence to support it.
