From the WashPost re Climate and Environment: Science ranks grow thin in Trump administration. Some excerpts:

The exodus has been fueled broadly by administration policies that have diminished the role of science as well as more specific steps, such as the relocation of agencies away from the nation’s capital.

While the administration has come under fire for prioritizing the concerns of industry at the expense of science in government decisions, the cumulative effects are just beginning to appear after three years of Trump in the White House.
