Carbon capture is probably the only geoengineering thing you could do that isn’t going to be massively controversial. Probably not practical though.

The other options mentioned like messing with the atmosphere to make it reflect more heat into space will likely cause wars due to lack of global consensus

Who would attack who? Let’s say we are putting calcium carbonate into the upper arctic atmosphere to stop Greenland melt.

Who attacks?

These changes (very likely) cause major changes in precipitation. So whoever all the sudden gets a drought and famine.

[dr_dshiv]

Aren’t we facing major changes in precipitation (due to global warming) and by preventing global warming, having fewer changes?

TBH, I don't understand anti geoengineering logic…

[lazide]

Sure, but those ‘just happen’. If you start intentionally changing things, that next famine (or set of floods) has your name explicitly on it.

At some point countries will just start doing it out of desperation, but folks are rightly nervous to be the first.

Maybe not attacks but... "Congratulations you've won 100M+ climate refugees!"
