So NOAA employees have been told to stop working with foreign nationals
https://www.wired.com/story/noaa-employees-foreign-nationals/Before I bailed out of reality to get into this free-software adventure, I spent many years at the National Center for Atmospheric Research; it was a great time working on things that really mattered. One of the things I learned is that atmospheric science is an international exercise; international collaboration is the norm. Removing the US from that community will impede science worldwide, and deprive the US of the fruits of working with others. Many of the best researchers in this field are *not* in the US.
But something else crosses my mind. If they can kill scientific collaboration, they can go after other types of collaboration too. Like, say, ordering government agencies to stop participating in free-software projects where there are non-US developers present — all of them, in other words. Or telling government contractors that. An attempt to tear our community apart is not much of a stretch from where we are now.
We live in interesting times, alas.
