When I was in school it was taught that we are currently in an ice age and that the dimming caused by our pollution was blocking so much sunlight 40ish years ago that it countered warming and global temperatures levelled off. That the various Clean Air Acts have resulted in decreased levels of pollution, which in turn has caused warming to return that was occurring naturally in the first place. Granted this was a long time ago when it was part of the curriculum.
Regardless, climate change is of course a thing, but I am sure we will find a more creative way to fuck everything up before climate change does.
