It's a bit different than 9/11 though. Climate change is like a fully loaded supertanker. You can hit an emergency break all you want, but still that ship will have a 5..10km (or longer?) breaking distance.

So if a mass death event were to occur, and policy were to change course drastically, the changed climate would continue to pound our biosphere for many decades (if not centuries). Or hit tipping points and get worse & worse no matter what we do.

To put it blunt: at some point, prolonged mass suffering & death is practically guaranteed. Just with a decades-delayed fuse. That fuse is already lit, while we can't see (with any certainty, that is) how big a powder keg it goes into.
