> If it turns out that there are no serious side effects or risk Literally the only way to determine that would be to try it. And then let’s hope the proponents are correct, because if not... There is just so much we don’t understand about the global climate to think this sort of solution is a good idea. I’ll start taking the geoengineering people seriously when they can accurately predict the weather one month from now.

Predicting weather and predicting climate are almost completely different things. It's about predicting where a single state space trajectory of a chaotic system ends up versus predicting bounds and average positions for an ensemble of trajectories. The first is impossible, the second is routinely done. Think of a double pendulum, one can't predict where it is in an hour, but can predict reasonably accurately how high it can still go due to the amount of kinetic and potential energy it is going to have.
