As these things go, it's the lowest risk play I'm aware of. You can use it in a fairly specific area, like for example over a melting ice sheet. If you stop actively using it, the droplets precipitate out after a week or two, and everything goes back to the way it was. The biggest drawback, in fact, is that it is not permanent.

Dropping salt on a melting ice sheet does not sound like a great plan.

We'd really need to invest in really detailed computer models to make sure we're not overlooking something and shooting ourselves in the foot, IMO.

Well, if civilization was destroyed by spraying a fine mist of sea water into the air from the back of a boat, I guess I would feel pretty bad. But, that seems highly unlikely, and certainly less likely than that we'll destroy ourselves by continuing to do absolutely nothing to stop the climate from collapsing.
