I'm guessing you need permission to go deploy a bunch of buoys off the coast of Oregon, and that permission may be difficult to obtain for foreign research projects in the current US political climate.
I think you may have a hard time monitoring the Atlantic current if your sensors are all deployed off the coast of Oregon so it seems to me that this administration would jump at the opportunity to deploy those sensors off of the Oregon coast. Then they could tell the people that they are carefully monitoring the situation and can't find a problem. Nothing to see here, literally.
But the US is already doing it, it’s already there. It benefits the entire world to have this data. It’s not expensive.
Why reinvent the wheel? More, why not let another country take it over?
The reason is because there are those with ties to the American government’s current administration that have decided they will benefit tremendously from climate change and don’t care about its consequences.
In a great many cases when it came to academic measurement regarding any geological event or phenomenon, the US has historically been at the forefront and shared data with its allies. Very few of those countries have their own measurement systems set up because the US already has them ready to go anyway.
When the second wave of Trump idiocy hit academic institutions by forcing foreign institutions to sign a document indicating they "do not support DEI", this caused some major trouble. Public institutions gave in to the Americans' demands because there was no way to gather the information necessary to finish research in a reasonable time frame.
I think it's time Europe treated the USA the way they want to be treated, as an outsider and a potential threat, and that it's time to stop seeing them as a partner when it comes to science. We need our own measurements, our own instruments, our own satellites, our own databases, and we need to invest now.
Unfortunately, anti-intellectualism isn't just on the rise in the USA. Plus, now now that many countries are struggling with the increased fuel prices thanks to the USA's invasion of Iran, it's hard to find money to invest in science that a worrying amount of people choose to ignore/pretend doesn't exist because it doesn't suit their personal interests.
