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.

As long as is needed to transition away from burning fossil fuels. You can always put more in high altitude. If half the comments here are right and climate change is truly an apocalyptic threat, then acid rain and global dimming would be worthwhile tradeoffs.

If climate change isn't extremely bad, then maybe it's not worth it. But at some point, if it becomes existential, then all options are on the table.
