Officially, the Republic of Maldives, this island nation consists of 26 atolls and just under 1,200 islets, of which 250 are inhabited. With a maximum elevation of only 2.3 meters, and an average elevation of just 1.5 meters, it's easy to see why the Maldives are going to get inundated by only a small increase in sea levels.
