What country is going to take the hit and start the high altitude sulfur spraying? If we even could get the forcing back to what it already was in the recent past that would be a great help.

How long would that temporary measure help?

What would that do to acidic rain, global dimming, ecology and agriculture.

Masking the problem will only make it come back harder when measures don't scale up anymore. Then there'll be no time to do much more.

If (e.g.) China stops the US can start, or if a small country can't scale up enough more countries can join in. The whole "termination shock" thing is highly overrated, it's solvable with next to no communication at all. Decision rule: if not enough is being sprayed according to your models, make up the difference yourself.
