"The Trump administration has rolled back Obama-era climate policies at a brisk pace in the first year of Donald Trump's presidency. But it has been equally aggressive in minimizing the climate science that justified those regulations in the first place.
A common assertion during the confirmation hearings for Trump's Cabinet members was that climate science is unclear, even though the scientific community found years ago that humans are driving global warming at an unprecedented pace. In some cases, references to climate change on government webpages disappeared minutes after Trump took office. Supporters say the administration is imprinting its own priorities on federal research, as all presidential administrations do. Critics contend it's part of a sweeping effort to downplay or degrade climate science.
"The appreciation of what science is and how science works, what science needs to thrive are things that people understand less and less, not more and more. That's what I find most troubling," said Rush Holt, CEO of the American Association for the Advancement of Science."
