First...what exactly does the "Department of Energy" do for us in the US?
I honestly don't know and will look it up, but if anyone can enlighten me, I'd be interested in a quick read.
I guess not everyone is aware because it seems unexpected, but the DoE is a major funder of science in the US. They are in charge of the 10 United states national labs where a big portion of major US research projects reside. I just finished grad school in physics working at Brookhaven National Lab and a lot of science happens at these places in a wide range of fields. There are some US government employed scientists/researchers but there is also huge involvement from all manner of Universities across the the world. Go google the DoE office of science to learn more. They fund a lot of energy and nuclear focused research to be sure, but there is a lot of other fundamental science research as well. As you can see in their budget here (http://science.energy.gov/~/media/budget/pdf/sc-budget-request-to-congress/fy-2016/FY_2016_Office_of_Science-Overview.pdf), they have a 5 Billion dollar line item for "Science" in 2016.
This situation is a big deal because Trump's administration is basically approaching a central chunk of the US (and to some extent international) scientific community saying he want's a list of everyone who supports climate research. This is bad news if you support climate research and bad news if you support a free and independent scientific community.
