Melting ice sheets could raise sea levels high enough to flood coastal areas around the globe by the end of the century, according to scientists gathering in Denmark today for a three-day climate-change conference. The phenomenon could affect regions including Florida, the Netherlands, Bangladesh, and the Maldives, the British Guardian newspaper reports.
The meeting, which brings 2,000 scientists to Copenhagen, is a run-up to December's international climate talks, where officials are set to draft a successor to the Kyoto treaty to limit carbon dioxide emissions. Experts will also update the work of the Intergovernmental Panel on Climate Change (IPCC), which released its findings on global warming two years ago. Some of that new information centers on the effects of glacier melts in Greenland and Antarctica.

Despite a slowing global economy, carbon dioxide emissions continued to rise in 2007, according to energy use figures from oil company BP—jumping to 8.47 billion metric tons of the most common greenhouse gas responsible for global warming or 2.9 percent higher than the last year's total. Leading the charge: the U.S. (up nearly 2 percent to 1.58 billion metric tons) and China (up more than 7 percent to 1.8 billion metric tons).
These figures outpace even the worst-case projections of the U.N. Intergovernmental Panel on Climate Change, which warned last year that unless pollution is reduced, global average temperatures could rise by between four and 11 degrees Fahrenheit (two to six degrees Celsius).
