Antarctica Melted in the Past, and As the Climate Warms, It's Poised to Melt Again
2013-07-24 11:47:00| Climate Ark Climate Change & Global Warming Newsfeed
Time: When it comes to polar melting, the Arctic hogs all the attention. And not without reason--last summer Arctic sea ice melted to its smallest extent on record, 49% below the 1979-2000 average. During the first two weeks of July, sea ice declined 61% faster than the 1981-2000 average, according to the National Snow and Ice Data Center. As sea ice melted, Arctic shipping set a record, with trips quadrupling in 2013 from the year before. The Arctic permafrost--the frozen soil that covers much of the...

How stable is the East Antarctica ice sheet?
2013-07-22 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Summit Voice: The biggest ice sheet in the world may be more susceptible to a warming climate than previously believed. New evidence garnered from mud deposits suggests that the East Antarctica Ice Sheet may have experiences significant melting about 5 million years ago enough to raise sea level by about 60 feet worldwide, according to researchers from Imperial College London. The study, published last week in the journal Nature Geoscience, shows that there was repeated melting between five and three million...
Oceans around Antarctica could become massive protected sanctuary
2013-07-15 20:46:00| Climate Ark Climate Change & Global Warming Newsfeed
Mother Nature Network: Millions of square miles of ocean off the coast of Antarctica could potentially become a marine sanctuary protecting thousands of species from exploitation unless Russia and China object, that is. The possible ocean sanctuary which would be the world's largest will be discussed next week by the member nations of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which will meet in Germany beginning on July 21. Two separate proposals are on the table to protect...

Massive Iceberg Breaks off Pine Island Glacier in Antarctica
2013-07-10 21:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: An enormous slab of ice, about a quarter the size of Rhode Island and some 200 feet thick, has broken away from Antarctica, according to German researchers. The event, which was recorded by radar aboard Germany's orbiting TerraSAR-X satellite, was not unexpected. In 2011, a NASA satellite noted that a huge crack had appeared in the ice shelf at the outlet of the frozen continent's Pine Island Glacier. "At some point, it had to happen,' said Angelika Humbert, a glaciologist at the Alfred Wegener...

Iceberg size of Chicago breaks off Antarctica glacier
2013-07-10 19:51:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: A massive iceberg, larger than the city of Chicago, broke off of Antarctica's Pine Island Glacier on Monday, July 8, and is now floating freely in the Amundsen Sea, according to a team of German scientists. The newborn iceberg measures about 278 square miles (720 square kilometers), and was seen by TerraSAR-X, an earth-observing satellite operated by the German Space Agency (DLR). Scientists with NASA's Operation IceBridgefirst discovered a giant crack in the Pine Island Glacier in October 2011,...
