Marine Cloud Brightening

The idea behind marine cloud brightening is to make clouds more reflective. Vessels could spray a fine mist of seawater into the atmosphere and it would be controlled remotely by computers. There's even a claim that spring 10 cubic meters of water a second into the right spots of the atmosphere could undo all the damage we've done up to now. But at this point, they're just concept drawings. We're not quite there yet with this technology.
