The article states that a loss of 100,000 cubic kilometers of ice would result in a half-meter rise in sea level. That means that if the 32 million km³ polar ice pack melts, sea levels will rise 160 meters. But I have always heard a figure of around 50 feet. Being on a small island in the South Pacific makes the matter less than academic.
