Arctic Melting Fast; May Swamp U.S. Coasts by 2099 Brian Handwerk for National Geographic News November 9, 2004 Scientists have determined that the ice in Greenland and the Arctic is melting so rapidly that much of it could be gone by the end of the century. (See photos from the Arctic.) The results could be catastrophic for polar people and animals, while low-lying lands as far away as Florida could be inundated by rising sea levels. (Read a story, see a map of how warming may toast Florida's coast). The Arctic Climate Impact Assessment was released yesterday. It will be discussed by the Arctic Council (the governments of Canada, Denmark, Finland, Iceland, Norway, the Russian Federation, Sweden, and the U.S., as well as six indigenous-peoples organizations) at a meeting in Iceland today. The four-year study of the Arctic climate involved an international team of more than 300 scientists. They used a number of climate models and made a "moderate estimate" of future emissions of carbon dioxide and other greenhouse gases that are widely believed to be contributing to the recent warming trend of the Earth's climate. The study concluded that in Alaska, western Canada, and eastern Russia, average temperatures have increased as much as 4 to 7 degrees Fahrenheit (3 to 4 degrees Celsius) in the past 50 years, nearly twice the global average. Temperatures are projected to rise 7 to 13 degrees Fahrenheit (4 to 7 degrees Celsius) over the next hundred years. The rising temperatures are likely to cause the melting of at least half the Arctic sea ice by the end of the century. A significant portion of the Greenland ice sheet—which contains enough water to raise the worldwide sea level by about 23 feet (about 7 meters)—would also melt. news.nationalgeographic.com
