Climate models overheat Antarctica Washington DC (SPX) May 08, 2008 
Computer analyses of global climate have consistently overstated warming in Antarctica, concludes a new study. The findings can help scientists improve computer models and determine if the southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise. "We can now compare computer simulations with ob ... read more |

Southern Flavor In The Arctic
New York NY (SPX) May 06, 2008Scientists probing volcanic rocks from deep under the frozen surface of the Arctic Ocean have discovered a special geochemical signature until now found only in the southern hemisphere. The rocks were dredged from the remote Gakkel Ridge, which lies under 3,000 to 5,000 meters of water; it is Earth's most northerly undersea spreading ridge. The study appears in the May 1 issue of the leading ... more Baltic sea ice cover hits an all-time low: meteorologists 
Stockholm (AFP) May 3, 2008The extent of ice covering the Baltic sea this winter reached an all-time low, since measurements began more than a century ago, Swedish meteorologists said. "Overall, 49,000 square kilometres (around 19,000 square miles) of the Baltic sea were covered in ice compared to the usual 180,000 square kilometres," the Swedish Meteorological Agency (SMHI) said. That was just over a quarter of ... more CU-Boulder Researchers Forecast 3-In-5 Chance Of Record Low Arctic Sea Ice In 2008 
Boulder CO (SPX) May 02, 2008New University of Colorado at Boulder calculations indicate the record low minimum extent of sea ice across the Arctic last September has a three-in-five chance of being shattered again in 2008 because of continued warming temperatures and a preponderance of younger, thinner ice. The forecast by researchers at CU-Boulder's Colorado Center for Astrodynamics Research is based on satellite ... more The Antarctic Deep Sea Gets Colder 
Bremerhaven, Germany (SPX) Apr 29, 2008The Antarctic deep sea gets colder, which might stimulate the circulation of the oceanic water masses. This is the first result of the Polarstern expedition of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association that has just ended in Punta Arenas/Chile. At the same time satellite images from the Antarctic summer have shown the largest sea-ice extent on record ... more Arctic Ice More Vulnerable To Sunny Weather 
Boulder CO (SPX) Apr 28, 2008The shrinking expanse of Arctic sea ice is increasingly vulnerable to summer sunshine, new research concludes. The study, by scientists at the National Center for Atmospheric Research and Colorado State University, finds that unusually sunny weather contributed to last summer's record loss of Arctic ice, while similar weather conditions in past summers do not appear to have had comp ... more |

Bremerhaven, Germany (SPX) Apr 15, 2008For the first time, a German has taken part in a Russian drift expedition and has explored the atmosphere above the central Arctic during the polar night. Jurgen Graeser, a member of the Potsdam Research Unit of the Alfred-Wegener-Institute for Polar and Marine Research in the Helmholtz Association, has just returned home to Germany. As a member of the Russian expedition NP 35 (35. North ... more NASA Researcher Visits One Tough P.I.G. 
Greenbelt MD (SPX) Apr 15, 2008Robert Bindschadler is chief scientist of NASA's Hydrospheric and Biospheric Sciences Laboratory, a senior fellow of the Goddard Space Flight Center, a fellow of the American Geophysical Union and a past president of the International Glaciological Society. This past January, Bindschadler led an expedition to a previously untouched part of Antarctica that may be one of the best places to gauge ... more NOAA Aircraft To Probe Arctic Pollution 
Boulder CO (SPX) Apr 09, 2008NOAA scientists are now flying through springtime Arctic pollution to find out why the region is warming - and summertime sea ice is melting - faster than predicted. Some 35 NOAA researchers are gathering with government and university colleagues in Fairbanks, Alaska, to conduct the study through April 23. "The Arctic is changing before our eyes," said A.R. Ravishankara, director of the ch ... more Austrian glaciers shrink the most in five years 
Vienna (AFP) March 29, 2008Austria's glaciers retreated more than 22 metres (24 yards) on average last year, in the biggest shrinking for five years, the country's Alpine Club said Saturday. "All glaciers experienced melting and retreated... an average of 22.2 metres" in the 2006-2007 period, the Alpine Club said, citing measurements of 93 glaciers by its specialists who blamed milder than normal temperatures. The ... more Antarctic Ice Shelf Disintegrating As Result Of Climate Change 
Boulder CO (SPX) Mar 26, 2008Satellite imagery from the University of Colorado at Boulder's National Snow and Ice Data Center shows a portion of Antarctica's massive Wilkins Ice Shelf has begun to collapse because of rapid climate change in a fast-warming region of the continent. While the area of collapse involves 160 square miles at present, a large part of the 5,000-square-mile Wilkins Ice Shelf is now supported on ... more |

Bozeman MT (SPX) Mar 11, 2008John Priscu normally works in Antarctica during its warmest and longest days. He usually shares the continent with scientists from all over the world. This year is different. The Montana State University scientist with an international reputation for polar research is spending his 24th season in Antarctica with no other researchers except the 17 members of his team. They're there for 2 1/2 ... more Seal cubs threatened by global warming, WWF warns 
Hamburg, Germany (AFP) March 10, 2008Hundreds of newborn seal cubs risk dying of hunger and cold because global warming is making ice in the Arctic Circle melt too fast, the World Wide Fund for Nature in Germany warned Monday. "In some parts perhaps not a single one of the seal cubs born in the past few weeks will survive," the WWF said in a statement. It said hundreds of the roughly 1,500 ringed seal cubs born this month ... more Polar bears in your yard? Call the Polar Bear Hotline 
Churchill, Canada (AFP) March 8, 2008It's 3:00 am and there's a polar bear in your yard. Who you gonna call? In Churchill, a town of some 1,000 people on the western shore of Hudson Bay, it's the Polar Bear Alert Team. The Polar Bear Hotline's not ringing these days, but the rangers who man the phone here are ready to spring into action when the ice in the bay starts to melt in a few months. Shaun Bobier, a district ... more New Method to Estimate Sea Ice Thickness 
Anchorage AK (SPX) Mar 06, 2008Scientists recently developed a new modeling approach to estimate sea ice thickness. This is the only model based entirely on historical observations. The model was developed by scientists with the U.S. Geological Survey and the Russian Academy of Sciences, Moscow. Using this new technique, the thickness of Arctic sea ice was estimated from 1982 to 2003. Results showed that average ice this ... more Warming Climate May Cause Arctic Tundra To Burn 
Washington DC (SPX) Mar 05, 2008Research from ancient sediment cores indicates that a warming climate could make the world's arctic tundra far more susceptible to fires than previously thought. The findings, published this week in the online journal, PLoS ONE, are important given the potential for tundra fires to release organic carbon - which could add significantly to the amount of greenhouse gases already blamed for global ... more
