“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, so no, I would not agree that it’s a primary contributor to the global warming that we see,” he told CNBC. “We need to continue the debate and continue the review and the analysis.”
The majority of the scientific community agrees with the finding that humans are the primary cause of global warming. And as NASA puts it, carbon dioxide emissions are “the most important long-lived ‘forcing’ of climate change.” Scientists at the United Nations have warned that the planet will be in dire straits if nations don’t dramatically decrease their carbon emissions. So it’s problematic that the man in charge of U.S. environmental regulations doesn’t think his agency should focus on working toward that goal.
