Global warming is causing the Arctic ice-cap to melt at such an unprecedented rate that by the summer of 2070 it may have no ice at all, according to the most comprehensive study carried out on global climate change in the region.

Are we really heading for an ice-free Arctic? More than 50,000 researchers hope to find an answer during a massive study of how global warming and other phenomena are changing the coldest parts of the Earth &#151; and what that means for the rest of it.

Global warming is heating the Arctic almost twice as fast as the rest of the planet in a thaw that threatens the livelihoods of millions of people and could wipe out polar bears by 2100, according to an eight-nation report released on Monday.

Scientists say changes in the earth's climate from human influences are occurring particularly intensely in the Arctic region, evidenced by widespread melting of glaciers, thinning sea ice and rising permafrost temperatures.

The rate of Arctic ice loss has shot up dramatically in recent years, scientists say, with the region losing 14 percent of its perennial ice cover&#151;an area the size of Texas&#151;between 2004 and 2005.

Global warming (news - web sites) is melting the Arctic ice faster than expected, and the world&#39;s oceans could rise by about a meter (3 feet

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.
