And the answer is that if we turned all of our energy to salt production, it wouldn’t even be a drop in the ocean, and our efforts would of course liberate more CO2 and contribute to global warming. Of all the possible ways we could geoengineer (all of them bad ideas frankly) this has to be one of the worst, least effective, most limited, and least likely to succeed. If we’re going to hasten our demise, we might as well try sulfate aerosols or something with a more global effect. We’d still end up killing ourselves, but at least it wouldn’t be quite so much like trying to get a sailboat to move by blowing on the sails.
