NASA: "Antarctic Ice Shelf a Few Years from Disintegration"

The Research Focused on a Remnant of the So-Called, Larsen B Ice Shelf, which has Existed for at least 10,000 Years but, Partially Collapsed in 2002. What is Left Covers about 1,600 Square km, about Half the Size of Rhode Island. Antarctica has Dozens of Ice Shelves - Massive, Glacier-Fed Floating Platforms of Ice that Hang over the Sea at the Edge of the Continent's Coast Line. The Largest is Roughly the Size of France. Larsen B is Located in the Antarctic Peninsula, which Extends toward the Southern Tip of South America and is One of 2 Principal Areas of the Continent Where Scientists Have Documented the Thining of such Ice Formations. "This study of the Antarctic Peninsula glaciers provides insights about how ice shelves farther south, which hold much more land ice, will react to a warming climate", Said Eric Rignot, Co-Author of the Study and a Glaciologist at NASA's Jet Propulsion Laboratory in Pasadena, California.


Almost 200 Countries Have Agreed to Negotiate a United Nations Pact by the End of 2015 to Combat Global Climate Change, which Most Scientists Expect will Bring about More Flooding, Droughts, Heat Waves and Higher Seas. The U.N. Intergovernmental Panel on Climate Change has Cited a Probability of at least 95% that Accelerated Warming of the Planet has been Triggered by Human Activities, Led by Atmospheric Emissions of Greenhouse Gases from the Burning of Fossil Fuels. The Study, Published Online in the Journal Earth and Planetary Science Letters, was Based on Airborne Surveys and Radar Data. The Study's Lead Scientist, Ala Khazendar, Said Analysis of the Data Reveals that a Widening Rift in Larsen B will eventually Break it Apart Completely, probably Around the Year 2020. Once that Happens, Glaciers Held in Place by the Ice Shelf will Slip into the Ocean at a Faster Rate and Contribute to Rising Sea Levels, Scientists Say. The Study also Found Leppard and Flask, 2 Main Tributary Glaciers of the Ice Shelf, Have Thinned by between 20 and 22 Meters in Recent Years and the Pace of their Shrinking has Accelerated since the Immediate Aftermath of the 2002 Partial Collapse of the Ice Shelf.
