Warming Oceans May Threaten Krill, a Cornerstone of the Antarctic Ecosystem

New York Times: Every day for a week, So Kawaguchi peered intently into the jars of cold water holding harvested krill eggs. None were hatching. In his laboratory in Hobart, Tasmania, on the edge of the Southern Ocean, he could see that the carbon dioxide he had pumped into the icy seawater had killed the eggs. Stories from Our Advertisers We thought the krill might be more robust, said Dr. Kawaguchi, a biologist who works for the Australian governments Antarctic Division. We were not expecting such a clear...

Rate of Antarctic ice melt to double by 2050 study
2015-10-14 18:10:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Home: Antarctica, the planets largest desert, is home to 90% of the worlds ice enough to raise global sea levels by at least 60 metres. So what happens to its ice and snow is a matter of serious concern to all of us. One group has just predicted that, by 2050, the rate at which the ice shelves melt will double. Another reports that powerful winds are not just shifting Antarcticas snow, but are also blowing 80 billion tonnes of it away, into the sea or the atmosphere. Both cases exemplify the...
Antarctic Ice Melt Will Double by 2050, Say Experts
2015-10-13 19:05:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Recently, researchers have pointed out that Antarctica's melting hasn't been as intense as many climate change experts had feared. However, new research has revealed that this is all about to change, with new data hinting that the White Continent's surface will double its current melt rate by 2050. Specifically, investigators with the Royal Netherlands Meteorological Institute, the Institute for Marine and Atmospheric Research at Utrecht University, the Woods Hole Oceanographic Institution (WHOI)...
Melting of Antarctic Ice Shelves Could Double by 2050, Dramatically Increasing Sea Level Rise
2015-10-13 17:00:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: If countries act fast to reduce global greenhouse gas emissions, according to new research, there is still time to curtail the most cataclysmic Antarctic ice melt. However, according to a study published Monday in the journal Nature Geoscience, if fossil fuel consumption maintains its current rate, Antarctica may experience a widespread collapse of its ice shelves, which could spur significant sea level rise. Researchers employed a combination of satellite observations of ice surface melting and...

Melting of Antarctic ice shelves set intensify
2015-10-12 21:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: New research published today projects a doubling of surface melting of Antarctic ice shelves by 2050 and that by 2100 melting may surpass intensities associated with ice shelf collapse, if greenhouse gas emissions from fossil fuel consumption continue at the present rate. Ice shelves are the floating extensions of the continent's massive land-based ice sheets. While the melting or breakup of floating ice shelves does not directly raise sea level, ice shelves do have a "door stop" effect: They...
