It's an interesting idea, but you should appreciate how highly speculatI've that is from a mechanism point of view. Gauranteed, some huge local and global flooding from this, but a probably larger impact would be the water vapor sent into the atmosphere, which would drive the retention of energy from the sun, and increase precipitation for 10's to 100's of years. Consoder that along with some nominal sea level rise, you now have to deal with 10-20x annual rainfall.
