Science got off to a rocky start even before President Trump was sworn in. On the stump, he vowed to reduce the Environmental Protection Agency to "little tidbits." On inauguration day, web pages on climate change from the Obama White House disappeared, the National Parks Twitter account was reined in, and soon after, staff at the Interior, Agriculture, health and human services and the EPA were told to stop communicating directly with the public. And then there's Scott Pruitt, Trump's choice to head the EPA, who's been a friend to oil and gas and an opponent to the agency he wants to lead. All of this has scientists of all stripes fighting back with projects to preserve climate data at risk of vanishing, and are planning a march on Washington.
