A Test of Cloud-Brightening Machines Poses No Health Risk, Officials Say
After halting a test of controversial technology to fight global warming, the city of Alameda, Calif., said it had found no “measurable health risk” from the giant salty-mist-spraying fans.

Somehow I am not convinced that spraying salt water into clouds is without risks. Somewhere, all the salt will come down as salty rain after all. I guess farmers will be exited about this when they can harvest pre-salted tomatoes...
I believe it's mostly being suggested over the ocean. There's a great Hank Green video about this tech.
During the cold war, the Americans (and probably the Russians, too) seeded clouds and checked where the stuff ended up to see how radioactive fallout would work. The result was: basically everywhere.
I don't think this is looking at seeding the stratosphere but replacing the sulfur based localized cloud creation that container ships have stopped producing with seawater based local cloud creation. I don't think anyone thinks it will have zero negative effects, but we are at a point where we have unexpectedly good data from the sudden dropoff of sulfur shipping fuels and a very urgent need to address this specific issue.

The video linked is actually a bit more anti the whole idea than I am I think but what do I know, he has a climate science PHD. It is a complex issue and a lot of people will die no matter what we do, especially if we do not dramatically reduce our climate impact overall.
