The Short Answer

The surface of the oceans across the world is about 500 million square kilometers (roughly two hundred million square miles). To reduce the level of the earth's oceans by one millimeter (about one 25th of an inch), you'd have to pump five hundred thousand cubic kilometers – or about 120000 cubic miles of water (a cube that's 50 miles on each side) into a desert… AND THEN KEEP IT THERE and don't let any of it evaporate or it'll just fall back into the oceans as rain. And that's just for reducing the level of the oceans by one millimeter.
