"If there was any doubt over President Trump's views on climate change, those doubts evaporated with the unveiling of his proposed federal budget on Thursday.
The budget would end programs to lower domestic greenhouse gas emissions, slash diplomatic efforts to slow climate change and cut scientific missions to study the climate.
"It's terrible from the perspective of having any concern at all about climate change," says Andrew Light, a senior fellow at the World Resources Institute's climate program and a professor at George Mason University.
"They can cut the funding, but climate change is real and we're going to have to deal with it," says Chris McEntee, director of the American Geophysical Union. "Slashing this kind of funding is not going to assist in building the resiliency to climate and the impacts of climate change that this country needs.""
