A visit to the island nation of Kiribati, which could be the first country to be lost from rising tides due to global warming:
Kiribati is a flyspeck of a United Nations member state, a collection of 33 islands necklaced across the central Pacific. Thirty-two of the islands are low-lying atolls; the 33rd, called Banaba, is a raised coral island that long ago was strip-mined for its seabird-guano-derived phosphates. If scientists are correct, the ocean will swallow most of Kiribati before the end of the century, and perhaps much sooner than that. Water expands as it warms, and the oceans have lately received colossal quantities of melted ice. A recent study found that the oceans are absorbing heat 15 times faster than they have at any point during the past 10,000 years. Before the rising Pacific drowns these atolls, though, it will infiltrate, and irreversibly poison, their already inadequate supply of fresh water. The apocalypse could come even sooner for Kiribati if violent storms, of the sort that recently destroyed parts of the Philippines, strike its islands.
