Donald Trump campaigned on promises to make it easier to drill for oil and burn coal. He pledged to leave only “tidbits” of the Environmental Protection Agency in place, and to pull the U.S. out of international climate treaties. “We’re going to cancel the Paris Climate Agreement," he said last May, "and stop all payments of U.S. tax dollars to U.N. global warming programs.” Today we hear from two University of Maryland experts: First, we talk with Robert Orr, head of the School of Public Policy at the University of Maryland, College Park. He’s also senior advisor to the United Nations on climate change. Then Donald Boesch, president of the University of Maryland Center for Environmental Science, joins us.
