Antarctic glaciers are thinning and slipping ever faster into the sea, according to several new studies. Warmer air and sea temperatures are blamed, and the changes are expected to cause an appreciable rise in sea levels.

A faster-than-expected thaw of the Arctic is likely to open legendary short-cut routes between the Pacific and the Atlantic but experts say icebergs and high costs will prevent any trans-polar shipping boom.

WASHINGTON - Scientists say changes in the earth&#39;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.

â¢ Glaciers in the Antarctic and Greenland are melting much faster than expected, and the world&#39;s fastest-receding glacier, the Grand Pacific in Glacier Bay, Alaska, has doubled its rate.

Arctic ice coverage has receded this week to record lows, the European Space Agency said, raising the prospect of greater maritime traffic through a long-sought waterway known as the Northwest Passage.

The burning of fossil fuels has contributed to warming in the Arctic that is much faster and more dramatic than scientists previously believed at nearly twice the rate of the rest of the world, a new international report concludes.
