On the weather front (lol) one of project 2025s goals is to break up the NOAA. They want to do it specifically to hamper the ability for anyone to show the ongoing effects of climate change. If anyone thinks this is a conspiracy theory, it's an actual conspiracy, and here is the direct quote from project 2025.
Together, these form a colossal operation that has become one of the main drivers of the climate change alarm industry and, as such, is harmful to future U.S. prosperity. This industry’s mission emphasis on prediction and management seems designed around the fatal conceit of planning for the unplannable. That is not to say NOAA is useless, but its current organization corrupts its useful func- tions. It should be broken up and downsized.
Weather is global, so agencies like the NOAA collect data from satellites, weather balloons, weather stations, buoys, etc. all over the world. NOAA's data is a bit like GPS: paid for by US taxpayers, but used for the common good across the globe. Shutting them down wouldn't just hurt weather prediction in the US, it would hurt everyone. Other developed countries can absolutely predict their own weather, but if they can't include the volume of data generated by the US, their accuracy will suffer (and obviously likewise if the US couldn't use EU data or whatever).
