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://phys.org/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://phys.org/news161027942.html Space & Earth Fri, 08 May 2009 18:59:23 EST news161027942 Out of place in the snowy, polar landscape, the train that once hauled coal out of the mountain serves as a reminder to scientists at the Ny-Aalesund Arctic research station of the origin of the planet's woes. http://phys.org/news160989825.html Space & Earth Fri, 08 May 2009 08:24:54 EST news160989825 (AP) -- A decision involving the iconic polar bear could determine whether protecting endangered species might also help save the earth from global warming. http://phys.org/news160983691.html Biology Fri, 08 May 2009 06:42:08 EST news160983691 Researchers in Canada are reporting for the first time that high mercury levels in certain Arctic seals appear to be linked to vanishing sea ice caused by global warming.
