The Arctic ice cap is melting faster than scientists had expected and will shrink 40 percent by 2050 in most regions, with grim consequences for polar bears, walruses and other marine animals, according to government researchers.

Greenhouse gases have contributed to a gradual warming of the ecologically-fragile Arctic region, causing massive climate changes, including melting glaciers and sea ice, according to a soon-to-be-released environmental study.

If global warming continues unabated, melting ice could trigger a positive feedback loop that would cause sea ice to decline steadily for decades and then abruptly disappear.

For 5,000 years, great tongues of ice have spread over the 3-mile-high slopes of Puncak Jaya, in the remotest reaches of this remote tropical island. Now those glaciers are melting, and Lonnie Thompson must get there before they're gone.

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.
