@pvonhellermannn I was wrong saying "up to". Should have written "can collapse in less than 100 years after the trigger point has passed".
What I tried to say was that we have up to 100 years of action, even in the worst case scenario.
We can remove almost all historic CO2 emissions in hundred years if we do it as fast as we burned the fossil fuels. Obviously not easy to do, but removing a substantial amount could delay trigger points
