As the presidential inauguration drew near in January, something bordering on panic was taking hold among some scientists who rely on the vast oceans of data housed on government servers, which encompass information on everything from social demographics to satellite photographs of polar ice.

In a Trump administration that has made clear its disdain for the copious evidence that human activity is warming the planet, researchers feared a broad crusade against the scientific information provided to the public. Reports last week that the administration is proposing deep budget cuts for government agencies including the National Oceanic and Atmospheric Administration and the Environmental Protection Agency have fueled new fears of databases being axed, if only as a cost-saving measure.

“We’ll probably be saying goodbye to much of the invaluable data housed at the NCEI,” Anne Jefferson, a water hydrology professor at Kent State University, wrote on Twitter Saturday, referring to the National Centers for Environmental Information. “Hope it gets rescued in time.”

It is illegal to destroy government data, but agencies can make it more difficult to find by revising websites and creating other barriers to the underlying information.
