They've been telling me the world was going to end soon since I was young. I was taught in college in the 80's that the earth was going to be in climate catastrophe by 2000 (and also that there was going to be no oil.)
I believe in science, just hear me out.
All these big predictions are based on n=0 actual data. We have scientific evidence of climate change in the past, yes, but it's all generated from models that came thousands of years later. Scientists didn't actually get to witness and record the event as it happened.
We don't know how long it will take climate change to hit and how bad it will be. We don't know how much is exactly anthromorphic and how much is exogenous.
Based on this uncertainty it's really shitty to teach children that they're not going to have a future because the climate is going to crush us all. But even if it were true, how fucked up is it to tell a child their life is hopelessly doomed when there is nothing they can do? Why not let the child obliviously enjoy a pretty fun part of life?
