Look I was alive and paying attention when carbon dioxide passed a threshold that is impossible to go back to. (Over 400ppm in the atmosphere.)
That was ten years ago.
Every climate scientist on the planet predicts society will collapse in the face of climate change.
But sure, keep your head buried in the sand by calling other people “doomers” because you can’t be fucked to look up publicly available scientific research.
I hope you are young so you get to see exactly how bad it gets and to question if maybe you were a dumb fuck to ignore it.
