Orleans, and low-lying countries such as the Netherlands or Bangladesh. A number of tiny island nations such as Vanuatu and the Maldives, which barely poke out above the ocean now, are already vanishing beneath the waves. Eventually their
entire population will have to move someplace else.7 Even a small sea level rise might not drown all these areas, but they are much
more vulnerable to the large waves of a storm surge (as happened with Hurricane Katrina), which could do much more damage than sea level rise
alone. If sea level rose by 6 m (20 feet), most of die world's coastal plains and low-lying areas (such as the Louisiana bayous, Florida, and most of
the world's river deltas) would be drowned. Most of the world's population lives in lowelevation coastal cities such as New York,
Boston, Philadelphia, Baltimore, Washington, D.C., Miami, and Shanghai. All of those cities would be partially or completely under water with
such a sea level rise. If all the glacial ice caps melted completely (as they have several times be...
