For the past two months ships from the countries have ventured north in icy areas of the Arctic where almost no surface ships have been, in an effort to find out how far the continental shelf extends. http://www.physorg.com/news171824277.html Space & Earth Thu, 10 Sep 2009 18:10:02 EST news171824277 A series of record-setting unmanned research flights are providing University of Colorado at Boulder researchers with some of the first 3-D observations of gaping holes in the Antarctic sea ice known as polynyas and the blasting winds that help form them. http://www.physorg.com/news171818910.html Space & Earth Thu, 10 Sep 2009 16:50:01 EST news171818910 (PhysOrg.com) -- Research published by climate scientists at the University of East Anglia (UEA) has been named one of the most highly-cited in its field in the last two years. http://www.physorg.com/news170328791.html Space & Earth Mon, 24 Aug 2009 10:34:03 EST news170328791 A runaway spurt of global warming 55 million years ago turned Earth into a hothouse but how this happened remains worryingly unclear, scientists said on Monday. http://www.physorg.com/news166715232.html Space & Earth Mon, 13 Jul 2009 14:47:39 EST news166715232 (PhysOrg.com) -- 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. http://www.physorg.com/news166204112.html Space & Earth Tue, 07 Jul 2009 16:49:12 EST news166204112 (AP) -- British explorers in northern Canada to measure the thickness of floating Arctic sea ice ended their expedition short of reaching the North Pole due to an early summer ice melt, the team said Thursday. http://www.physorg.com/news161540001.html Space & Earth Thu, 14 May 2009 17:13:55 EST news161540001 The mechanical behavior of the Arctic sea ice cover appears to favor its rapid decline. Scientists from INSU-CNRS, Université J. Fourier and Université de Savoie, France, have analyzed the trajectories of drifting buoys anchored in the ice and found that the mean drift rate and deformation rate of Arctic sea ice has strongly increased over the last three decades. These effects, related to the mechanical properties of the cover, contribute to the faster- than-expected decline of Arctic sea ice. This work is published in the 14 may 2009 issue of the Journal of Geophysical Research - Oceans. http://www.physorg.com/news161532044.html Space & Earth Thu, 14 May 2009 15:10:57 EST news161532044 (AP) -- The Obama administration, which promised a sharp break from the Bush White House on global warming, declared Friday it would stick with a Bush-era policy against expanding protection for climate-threatened polar bears and ruled out a broad new attack on greenhouse gases. http://www.physorg.com/news161027942.html Space & Earth Fri, 08 May 2009 18:59:23 EST news161027942 (AP) -- A decision involving the iconic polar bear could determine whether protecting endangered species might also help save the earth from global warming. http://www.physorg.com/news160983691.html Biology Fri, 08 May 2009 06:42:08 EST news160983691 Increased growth in Antarctic sea ice during the past 30 years is a result of changing weather patterns caused by the ozone hole according to new research published this week (Thurs 23 April 2009). http://www.physorg.com/news159528096.html Space & Earth Tue, 21 Apr 2009 10:22:00 EST news159528096 The threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, according to a new analysis. While global temperatures would rise, the most dangerous potential aspects of climate change, including massive losses of Arctic sea ice and permafrost and significant sea level rise, could be partially avoided. http://www.physorg.com/news158929344.html Space & Earth Tue, 14 Apr 2009 12:03:30 EST news158929344 (PhysOrg.com) -- A nearly ice-free Arctic Ocean in the summer may happen three times sooner than scientists have estimated.

Although the melt season did not break the record for ice loss, NASA data are showing that for a four-week period in August 2008, sea ice melted faster during that period than ever before. http://www.physorg.com/news141835526.html Space & Earth Sun, 28 Sep 2008 15:45:26 EST news141835526
