NASA scientists reported that higher temperatures and a retreat of the sea ice over the last two winters offered new evidence that the gases were influencing the ArcticÂs climate.

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.

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.
