Now, a team of researchers from nine institutions - including LSU - have been funded to the tune of $10 million dollars by the National Science Foundation, or NSF, to get to the bottom of things - literally. These scientists will drill through the West Antarctic Ice Sheet and Ross Ice Shelf in Antarctica to directly access a subglacial lake and the cavity below the ice shelf. http://phys.org/news178293790.html Space & Earth Tue, 24 Nov 2009 14:40:02 EST news178293790 A new study that reconstructed ocean temperatures from millions of years ago could provide new insight into how the Earth responds to climate change. http://phys.org/news178272697.html Space & Earth Tue, 24 Nov 2009 08:12:24 EST news178272697 Satellite observations and a state-of-the art regional atmospheric model have independently confirmed that the Greenland ice sheet is loosing mass at an accelerating rate, reports a new study in Science. http://phys.org/news177258173.html Space & Earth Thu, 12 Nov 2009 14:23:32 EST news177258173 (PhysOrg.com) -- A team of chemists from the U.S. and France has found compelling evidence of a previously undocumented large volcanic eruption that occurred exactly 200 years ago, in 1809. http://phys.org/news176049231.html Space & Earth Thu, 29 Oct 2009 15:35:09 EST news176049231 PHILADELPHIA -- An international team of environmental scientists led by the University of Pennsylvania has shown that sea-level rise, at least in North Carolina, is accelerating. Researchers found 20th-century sea-level rise to be three times higher than the rate of sea-level rise during the last 500 years. In addition, this jump appears to occur between 1879 and 1915, a time of industrial change that may provide a direct link to human-induced climate change. http://phys.org/news175969082.html Space & Earth Wed, 28 Oct 2009 17:18:47 EST news175969082 (PhysOrg.com) -- UC Santa Cruz researchers are among the leaders of a major Antarctic research project in which scientists will drill through a half-mile of ice to penetrate subglacial Lake Whillans and study hidden processes that govern the dynamics of the West Antarctic ice sheet. http://phys.org/news175361051.html Space & Earth Wed, 21 Oct 2009 16:50:01 EST news175361051 New ground measurements made by the West Antarctic GPS Network (WAGN) project, composed of researchers from The University of Texas at Austin, The Ohio State University, and The University of Memphis, suggest the rate of ice loss of the West Antarctic ice sheet has been slightly overestimated. http://phys.org/news175172992.html Space & Earth Mon, 19 Oct 2009 12:10:33 EST news175172992 NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets.

The key concern is how stable the ice cap actually is and new Danish research from the Niels Bohr Institute at the University of Copenhagen can now show the evolution of the ice sheet 11,700 years back in time - all the way back to the start of our current warm period. The results are published in the esteemed journal Nature. http://phys.org/news172327825.html Space & Earth Wed, 16 Sep 2009 14:20:08 EST news172327825 (PhysOrg.com) -- The ice sheets that sculpted the landscape of northern Britain moved in unexpected ways and left distinctive egg-shaped features according to new research. http://phys.org/news172300242.html Space & Earth Wed, 16 Sep 2009 06:20:01 EST news172300242 The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study. http://phys.org/news172072921.html Space & Earth Sun, 13 Sep 2009 15:50:06 EST news172072921 (AP) -- Suddenly and without warning, the gigantic river of ice sped up, causing it to spit icebergs ever faster into the ocean off southeastern Greenland. http://phys.org/news171821271.html Space & Earth Thu, 10 Sep 2009 17:39:32 EST news171821271 (PhysOrg.com) -- One major threat of planetary warming is the melting of the great polar ice sheets, and the resulting rise in global sea level. Particularly worrisome to researchers is the fragility of the West Antarctic ice sheet (WAIS), whose bed lies well below sea-level, accelerating the natural flow between the grounded ice sheet itself and the floating ice shelves that make up its boundary. http://phys.org/news170690352.html Space & Earth Fri, 28 Aug 2009 15:00:03 EST news170690352 (PhysOrg.com) -- A new international research effort on the Greenland ice sheet with the University of Colorado at Boulder as the lead U.S. institution set a record for single-season deep ice-core drilling this summer, recovering more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future. http://phys.org/news170516207.html Space & Earth Wed, 26 Aug 2009 15:10:01 EST news170516207 (PhysOrg.com) -- Lakes in Antarctica, concealed under miles of ice, require scientists to come up with creative ways to identify and analyze these hidden features.
