The northern coastline of Alaska midway between Point Barrow and Prudhoe Bay is eroding by up to one-third the length of a football field annually because of a "triple whammy" of declining sea ice, warming seawater and increased wave activity, according to new study led by the University of Colorado at Boulder. The conditions have led to the steady retreat of 30 to 45 feet a year of the 12-foot-high bluffs -- frozen blocks of silt and peat containing 50 to 80 percent ice -- which are toppled...

U.S. satellite measurements show Arctic sea ice extent in 2009 "“ the area of the Arctic Ocean covered by floating ice "“ was the third lowest since satellite measurements were first made in 1979. The ice area at minimum was an increase from the past two years, but still well below the average for the past 30 years. Arctic sea ice reached its minimum extent around September 12. According to scientists affiliated with the National Snow and Ice Data Center (NSIDC), sea ice coverage...

Remains On Downward Trend Despite a slight recovery in summer Arctic sea ice in 2009 from record-setting low years in 2007 and 2008, the sea ice extent remains significantly below previous years and remains on a trend leading toward ice-free Arctic summers, according to the University of Colorado at Boulder's National Snow and Ice Data Center. According to the CU-Boulder center, the 2009 minimum sea ice extent was the third lowest since satellite record-keeping began in 1979. The past five...

This summer's melt of Arctic sea ice might not have been quite as bad as the past two years, but satellite images reveal that it has now had the third biggest melt in 30 years, according to U.S. government scientists. The announcement was made on Thursday by the National Snow and Ice Data Center, which reported that the Arctic sea ice pack had reached its yearly minimum just last Saturday. It will not begin to grow again until fall begins. As of last Saturday, the sea ice only covered...

CU-Boulder's Snow and Ice Data Center analysis shows negative summertime ice trend continues The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center. While this year's September minimum extent was greater than each of the past two record-setting and near-record-setting low years, it is still...

WASHINGTON, July 7 /PRNewswire-USNewswire/ -- Arctic sea ice thinned dramatically between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record. The new results, based on data from a NASA Earth-orbiting spacecraft, provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover.

The new results, based on data from a NASA Earth-orbiting spacecraft, provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover. Scientists from NASA and the University of Washington in Seattle conducted the most comprehensive survey to date using observations from NASA's Ice, Cloud and land...

WASHINGTON, April 6 /PRNewswire-USNewswire/ -- The latest Arctic sea ice data from NASA and the National Snow and Ice Data Center show that the decade-long trend of shrinking sea ice cover is continuing. New evidence from satellite observations also shows that the ice cap is thinning as well. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) Arctic sea ice works like an air conditioner for the global climate system. Ice naturally cools air and water masses, plays a key role in...

NASA and the National Snow and Ice Data Center say that the decade-long trend of shrinking sea ice cover in the Arctic is continuing and new evidence suggests that the ice cap is thinning as well. Arctic sea ice naturally cools air and water masses and plays an important role in ocean circulation as well as reflecting solar radiation back into space. However, Arctic sea ice has been declining at a staggering rate in recent years. Satellite monitoring of Arctic sea ice showed that this winter...

A U.S. advisory panel on Thursday urged a ban on commercial fishing across a wide swath of the Arctic Sea off the Alaskan coast, in a pre-emptive measure against the effects of climate change. Proponents of the measure said it was the firs time the U.S. had acted to close a fishery as a result of climate change instead of in reaction to overfishing, Reuters reported. "Global climate change is making everyone think differently up here and making them understand that precautionary approaches...
