Despite the fact that every single one of my family members remembers 8 foot tall snow banks every single winter from 1960 to 1990, and we haven't seen anything even close to that basically since 1990, and they STILL claim climate change is a hoax.....
Remember, a convincing argument to these people was a Senator bringing a snowball onto the senate floor and claiming climate change can't be real because it still snows in DC. They do not give a fuck about the facts, they aren't stupid, they just don't care and think they will be able to survive, and they will enforce that belief by continuing to push for an insular US that shuts out the rest of the world and will likely have to start firing on desperate climate asylum seekers after about 30 years and eventually even that won't prevent the US from suffering under climate change so they will have to find scapegoats to blame the suffering on as things just continue to suck.
Most of them just DGAF because they are 80 years old and won't see any of the repercussions so they are happy to borrow value from the future to enrich themselves in the now. Even plenty of the Democrats don't seem to care to do anything because they'll be dead by then. Fuck, Feinstein refuses to vacate her seat seemingly because she needs the damn health insurance, which is probably the closest to being a normal american she has ever been.
