WASHINGTON (AP) - President Donald Trump's proposed budget would gut programs for science and the environment, reflecting the Republican's rejection of mainstream science.
Trump has frequently called climate change a "hoax," and his EPA chief, Scott Pruitt, said last week he does not believe carbon dioxide is a primary contributor to global warming. His proposed budget would cut the Environmental Protection Agency budget by 31 percent - nearly one-third - and eliminate more than 3,200 jobs.
That amounts to 20 percent of the agency's current workforce of 15,000.
"The president wants a smaller EPA. He thinks they overreach," said White House budget director Mick Mulvaney. "You can't drain the swamp and leave all the people in it."
The EPA budget would drop to $5.7 billion from its current $8.1 billion.
Trump's proposed budget goes far beyond EPA cuts.
It would eliminate funds for the Clean Power Plan, former President Barack Obama's signature effort to address climate change by restricting greenhouse gas emissions from coal-fired power plants.
Four different NASA Earth science missions would be shut down, including one championed by former Vice President Al Gore, a leading climate change activist.
The plan also would eliminate funding for the State Department's Global Climate Change Initiative and the U.N. Green Climate Fund, which help developing nations address climate change. It also would cut $250 million from National Oceanic and Atmospheric Administration grants that help coastal communities adapt to climate change, deal with invasive species and maintain healthy water and fisheries.
The budget also eliminates funding for regional programs to clean up the Great Lakes, Puget Sound and Chesapeake Bay, as well as Energy Star, a popular program to promote efficiency in home appliances. Midwest Republicans in Congress were upset with the Great Lakes program cut.
"Literally and figuratively, this is a scorched-earth budget that represents an all-out assault on clean air, water and land," said Gina McCarthy, who led the EPA in Obama's second term.
Margie Alt, executive director of Environment America, called the budget proposal "dirty and dangerous" and said it would cripple U.S. efforts to combat climate change.
"It is basically a 'get out of jail free card' for polluters," Alt said.
But Thomas Pyle, president of the American Energy Alliance, an advocacy group backed by billionaire brothers Charles and David Koch, said Trump's budget "offers a much-needed resetting of the relationship between the federal government, the states and the American people."
By slashing budgets for the EPA, Interior, Energy and other departments, Trump is taking needed steps to "eliminate the architecture of President Obama's politically motivated climate action plan" and re-emphasize the core mission at federal agencies, Pyle said.
Waleed Abdalati, NASA's former chief scientist and now head of an environmental science research institute at the University of Colorado, said Trump's budget "really make a troubling statement." The only reason to cancel the already-launched satellite championed by Gore "is not money - it's just you don't like it," he said.
Trump and other administration officials are wrong if they think ignoring global warming will make it go away, Abdalati added.
"Climate change will never disappear," he said. "It's not changing because we're studying it. We're able to meet the challenges associated with it because we're studying it. The Earth will go on doing what it does."
