Siberia's Lake Baikal, the world's largest and most biologically diverse lake, faces the prospect of severe ecological disruption as a result of climate change, according to an analysis by a joint US-Russian team in the May issue of BioScience. http://www.physorg.com/news160381259.html Space & Earth Fri, 01 May 2009 07:22:15 EST news160381259 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 (AP) -- Ice cover on the Great Lakes has declined more than 30 percent since the 1970s, leaving the world's largest system of freshwater lakes open to evaporation and lower water levels, according to scientists associated with the National Oceanic and Atmospheric Administration. http://www.physorg.com/news157053733.html Space & Earth Mon, 23 Mar 2009 19:03:50 EST news157053733 The ice cover in the Arctic Ocean at the end of summer 2008 will lie, with almost 100 per cent probability, below that of the year 2005 - the year with the second lowest sea ice extent ever measured. Chances of an equally low value as in the extreme conditions of the year 2007 lie around eight per cent. Climate scientists from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association come to this conclusion in a recent model calculation. http://www.physorg.com/news134823790.html Space & Earth Wed, 09 Jul 2008 12:03:10 EST news134823790
