IIRC, the Montreal protocol only worked because it could be solved with existing technology, quickly, with almost no economic cost and happened in a totally different era of global politics. Climate change has... well... none of that. Not only that, but by the time it gets bad enough to convince people, it may be literally impossible to stop. It's grim to think about, but if the nuke is falling it's too late to build an iron dome. We have several nuclear bombs dangling above us. We know they're there - permafrost, AMOC, ocean life collapse - just not exactly where, and we're blinding swinging a knife on a stick while actively yelling for a longer stick and telling the research committees not to tell them if they're getting close.
