I thought this was well understood? "Stratospheric aerosol injection", aka deliberately hurling sulphur into the upper atmosphere, is a know proposition: https://en.wikipedia.org/wiki/Stratospheric_aerosol_injectio...

It has a ring of "what could possibly go wrong?" about it. Doesn't mean it wouldn't work though.

Yeah, That's what I have been taught as well. Though the direct effect is very small and it's not part of many geoengineering plans because it is not great for us anyway. And you would also need to take into account the carbon footprint of manufacturing said aerosols.
