Life found in the muck of Antarctic lake
2013-09-11 15:23:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Researchers have found signs of life in mud pulled from the bottom of an ice-covered lake in Antarctica. Studying microbes in such extreme and closed-off environments could help scientists understand how life may thrive in the harshest places on Earth and potentially other planets. Scientists with the British Antarctic Survey and other institutions drilled through the ice sheet to dig up clean sediment samples from the bottom of Lake Hodgson, which is on the Antarctic Peninsula and 305 feet (93...

Proposal to Protect Antarctic Waters Is Scaled Back
2013-09-11 02:17:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: A proposal by the United States and New Zealand to create a huge ocean reserve in Antarctic waters has been sharply reduced in scale after opposition from Russia and other nations with large fishing industries. Environmentalists warned that the ambitious project was being badly undermined. The Ross Sea marine protected area that the two governments proposed last year was to have set aside about 875,000 square miles of the Southern Ocean where commercial fishing would be sharply limited. The area's...

Humpback Whales Present in Antarctic Waters Over Winter a Surprise to Scientists
2013-09-09 19:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Humpback whale researchers listening to underwater recordings got a surprise upon hearing data collected in Antarctic waters over winter. It had been assumed that all humpbacks migrate to equatorial waters during the winter, but acoustic data from underwater recording stations along the ice shelf revealed the sounds of humpback whales even during the austral winter months. The find came by way of a classic case of being in the right place at the right time, when researcher Ilse Van Opzeeland,...

West Antarctic Ice Sheet's Age Gains 20 Million Years
2013-09-06 16:11:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: The West Antarctic Ice Sheet could have formed 20 million years earlier than previously thought, researchers propose, after updating a detail in global climate models, placing more confidence in those models' ability to predict future changes in global climate. The West Antarctic Ice Sheet accounts for only about 10 percent of the ice on the continent today. It sits below sea level and is subject to melting from warm air and seawater infiltration, more so than the larger East Antarctic Ice Sheet,...
Antarctic moss a charming but chilling sign of warming
2013-08-30 20:53:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: A fleecy clump of moss growing on the Antarctic Peninsula might not seem like much of a sight to behold, but it`s a sign of a climate in flux. The patch of Polytrichum moss, sampled in 2008 by scientists at Alexander Island`s Lazarev Bay, either did not exist or was slumbering beneath ice when the peninsula was first spotted by Russian sailors in 1820. But now it is flourishing on ice-free rock - the world`s southernmost such moss bank. The Antarctic Peninsula is one of the fastest-warming...
