Al Gore said we were doomed by 2014. Was he a teenager when he said that. And by the way I do recall someone on these forums defending her saying. she's not an expert but she's telling us to trust the experts when they discuss about climate change. So since she's listening to the experts it's actually the experts who said this.
No, you're mischaracterizing those statements.
Gore was talking about keeping to 1 or 1.5ºC limits. We hit 1.5ºC global temp last year for the first time though it will be a few years before that is the average and not just a warmer, El Nino year.
Same with Greta, she was talking about stopping irreversible damage.
Speaking of which, the planet will hit 1.5ºC average in a few years and is on a path towards 3-4ºC, which will totally fuck it over for humanity.
While those temps aren't likely for another 50-75 years, we are either at or within a few years of the possibility of the AMOC shutting down entirely.
If you knew anything, you'd be shitting bricks about that possibility.
Its one of the reasons most climatologists are choosing not to have kids these days.
