In what some scientists see as another alarming consequence of global warming, thousands of Pacific walruses above the Arctic Circle were killed in stampedes earlier this year after the disappearance of sea ice caused them to crowd onto the shoreline in extraordinary numbers.

There's more to the recent dramatic and alarming thawing of the Arctic region than can be explained by man-made global warming alone, a new study found. Nature is pushing the Arctic to the edge, too.

Two-thirds of the world's population of polar bears could die out over the next 50 years, as warmer weather melts away the thick sheets of sea ice where the bears spend much of their lives, according to studies released yesterday by the U.S. Geological Survey.

Unless urgent action is taken to slow down global warming polar bears will be extinct by the end of the century. The stark warning is contained in an authoritative report compiled by more than 250 scientists on the effects of climate change in the Arctic.

Arctic regions are warming twice as fast as the rest of the world - a trend marked by melting glaciers, shrinking sea ice and climatic changes that are turning solid ground into swamps, exposing coastal villages to erosion and threatening wildlife.

Scientists have found that the ice in Greenland and the Arctic is melting so rapidly that most of it could be gone by the end of the century. Low-lying lands could be flooded and polar bears could go extinct, among other possibilities.
