Can confirm, I have 2 separate family members spewing this idiocy during visits. First it was that hurricane that shit on Georgia, Tennessee, etc. so "They" could shutdown a lithium mine or something (the people in the area want the mine, so that doesn't even make sense). It also lead to them to falling for all weather modification conspiracies on Facebook and YouTube. So now it's the floods out west... because "The Dems" want to make Texas look bad or something? I don't even know anymore.
Also, dry ice. They seem to think dry ice allows you to steer storms and will show me very obvious fake videos where people are dumping it into the water themselves, then recording and pretending they caught The Man doing it. All of the ice blocks are still square btw, like it was just dumped into the water. They still fall for it.
