My university physics professor was already going at the "climate change" crap back in his class in '85. I pretty much ignored him but I did remember his fervor.
I found it out of place in a very conservative university. Not that we knew anything about "climate change" but that most of us at that time were just thinking about making a life (and money) and didn't give a crap about that shit.
My university days were a lot different than those in current year.
edit: the "ice age" stuff started back in the 60s, read Larry Niven books, he had one about it.
air conditioners were destroying the planet and making acid rain
I remember that! Car a/c's ganged up on the ozone layer!
They brought CFCs up in my boy's class when he was in 4th grade and he asked her how all of the CFCs knew to go to the south pole and make a hole there. No answer from the teacher, of course.
Smart kid.

My retired dad had to have his AC recharged and instead of the $20 it used to cost it cost him $600. No scam here goy, look the other way.
