Our new president has already had a very disconcerting impact on science.

The most drastic actions have been a gag order on providing information about global warming at the Environmental Protection Agency and the National Oceanic and Atmospheric Administration, as well as information about energy from the Department of Energy.

There has also been a freeze on research grants already approved to scientists at Universities doing research in these areas.

Web pages at those agencies that provide information to the public and scientists have been shut down. Employees at those agencies have been told not to talk to the news media or anyone else about their work, period.

My colleagues feel that congress and the Trump administration are attacking science in an unprecedented manner.

Scientists are sufficiently concerned that they have organized a March for Science planned for April 22, and a People’s Climate March on April 29.
