My own solution to this issue: enlarge Palestine by dredging the Med to create some new land. I haven't done the sums yet, but this would also reduce sea levels globally, saving the Maldives etc.
We start with the total surface area of the sea, which is 139.5 million square miles. To get sea levels to drop by 12 inches, we do a sum to calculate how many cubic metres of stuff needs to be removed from the sea bed.
