I don't know how to calculate what it'd take to undo desertification of the dustbowl. But 1mm = 320km^3 of water that _doesn't_ go back into the ocean. To stop the current 2-3mm rise that's 1000 cubic km a year. I suppose over something the size of the dust bowl (400,000 sq km) that's not that much. But I'd take a wild guess that by the time we get to that level of terraforming, we can build solar reflectors and just prevent the warming in the first place. Desal'ing all that water is going to require massive amounts of power (big fusion plants) plus all sorts of machinery. Tossing a bunch of mirrors into space seems easier to my engineering-ignorant mind.
