Delivering the SO2 directly to the stratosphere needs some new tech to be developed.
Assuming that's done, the environmental side effects should be negligible, as I understand it. The stratosphere is pretty isolated from the atmosphere we live in, and the SO2 breaks down there over 1-2 years.

- BurningFrog 3y agoMy understanding is that sulfuric acid in the stratosphere is mostly broken down by sunlight, and the acid rain contribution from there is minimal. But I couldn't quickly find any supporting facts, so this is just me saying "I think I read that somewhere".
- CorrectHorseBat 3y agoBreak down into what and where else than down would it go?
- brucethemoose2 3y agoYeah... Its sulfer dioxide. I am no chemist, but I don't see a safe way that can come down.
- BurningFrog 3y agoDon't know, sorry. Maybe the main factor is that the SO2 stays up there for 1-2 years, which gives a lot of cooling "bang" for the acid rain "buck".
