New limits to Antarctic tourism
Washington (AFP) April 17, 2009US proposals for binding restrictions on Antarctic tourism have been adopted by countries with ties to the region, in a bid to protect the continent's fragile ecosystem, officials said Friday. Signatories of the Antarctic Treaty, launched in Washington 50 years ago, capped 11 days of talks in Baltimore, Maryland by agreeing to impose mandatory limits on the size of cruise ships landing in An ... read more *New* Comments: 0 NASA Flies To Greenland To Extend Polar Science 
Wallops Island, VA (SPX) Apr 17, 2009Imagine a piece of ice 1,000 miles long, 400 miles wide, and 2 miles thick in the center. That's the Greenland ice sheet. But that island-sized piece of ice is melting, so NASA researchers are flying to the Arctic this week to learn more about the nature of those changes. Researchers led by William Krabill of NASA's Wallops Flight Facility in Wallops Island, Va., embark this week on a mont ... read more *New* Comments: 0 UN agency sounds warning after Antarctica ice shelf rips 
Paris (AFP) April 7, 2009The UN Environment Programme (UNEP) said the breakway of a Jamaica-sized ice shelf from the Antarctic peninsula could accelerate global warming in this already vulnerable region. Satellite pictures show a 40-kilometre (25-mile) ice bridge that was the Wilkins Ice Shelf's last link to the coast had now shattered at its narrowest point, about 500 metres (yards) wide, UNEP said. The Wilkins ... read more *New* Comments: 0 Artic ice thinner than ever: scientists 
Washington (AFP) April 6, 2009The Arctic ice cap is thinner than ever, satellite observations revealed Monday, while also indicating that the sea ice cover continues to shrink due to global warming. This winter saw the fifth lowest maximum ice extent on record since monitoring by satellite began in 1979, said the Colorado-based National Snow and Ice Data Center (NSIDC). The period between 2004 and 2009 saw the lowest ... read more *New* Comments: 0 Arctic may be ice-free in 30 years: study 
Washington (AFP) April 3, 2009Some 80 percent of Arctic ice may disappear in 30 years, not 90 as scientists had previously estimated, according to a new study on the impact of global warming. "The amount of the Arctic Ocean covered by ice at the end of summer by then could be only about 1 million square kilometers, or about 620,000 square miles," said US researchers who authored the study published Thursday. "That's ... read more *New* Comments: 0 |
