Wars will be fought about water, and not only in the sense you think

As Gibson implied, the future comes first in scattered places: The incoming president of the Maldives has announced that the country will begin saving to buy a new place for its people to live, in case the islands are flooded by rising sea levels. It's actually not a bad idea, as the Maldives are only one meter above sea level, which is less than the rises predicted by some climate models. Its population is a bit less than four hundred thousand people (somewhat more than Iceland's, in case you were wondering). It'd certainly be a nontrivial migration project, but that's more the reason to begin to plan it as early as possible.
