“The Trump administration wants to destroy it. Why? Because NCAR attempts to understand the inequitable impacts of human-caused climate change on the poorest and most vulnerable.”
Threatening NCAR, Trump administration seeks to extinguish a beacon of climate science
The Trump administration’s world view is that the US doesn’t need a climate science brain trust because it doesn’t like what the brains say.

Whenever Trump announces some new authoritarian policy, like the ban on Harvard international students, the first two questions should always be:
1) Can he do that?
2) If he can't, will he get away with it?
More often that not, the answers are no. And I think this case will fit the pattern.
