The worst thing you can do when you're actively geoengineering is to abruptly stop doing it. So naturally we found a way we were already doing it and cut it immediately to make sure we fuck ourselves as much as possible :)
I'm almost convinced it's intentional at this point, the rich are busy building their offbrand vault tec bunkers and starting random wars for no real reason. Longtermism nonsense over the today.
Clearly worth the tradeoff of not making the worst catastrophe we've ever faced as a species exponentially worse?
I mean hell, piston engined airplanes use leaded fuel and crop dust it over everyone daily, but nobody cares as long as they get to fly them and that's a just minor money saving measure that causes a lot environmental consequences.
