Arctic ice shrinks as Antarctic ice expands
2014-10-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Australian Broadcasting Corporation: CHRIS UHLMANN: As Australians prepare for a long hot summer it's fair to say that not many of us are pondering the extent of sea ice in the Arctic. But scientists say we should be. The extent of the ice melt is both an important barometer and a cause of climate change. The latest satellite data shows the big melt has set in and that means big consequences for everything from walruses to the gases trapped by the permafrost. At the same time, ice closer to home in the Antarctic is growing but...

The truth about Arctic sea ice melt, and its inevitable denial
2014-10-07 20:49:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: First, the truth: After a summer of seasonal melting, on Sept. 17, 2014, Arctic sea-ice extent* likely hit its minimum for the year. The official word is that it was measured at 5.02 million square kilometers (1.94 million square miles). This is the sixth-lowest minimum since satellite records began in 1979. It also fits right in with the overall declining trend of Arctic sea ice: As you can see, back in the late 70s there used to be about 7.5 million square kilometers when ice hit its...

Antarctic Sea Ice Officially Hits New Record Maximum
2014-10-07 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: It's official: Antarctic sea ice hit its annual winter maximum on Sept. 22, reaching a record area of 7.76 million square miles, the National Snow and Ice Data Center (NSIDC) announced Tuesday. Antarctic sea ice extent for Sept. 22, 2014 was 7.76 million square miles. The orange line in the figure shows the 1981-2010 average extent for that day, and the black cross indicates the geographic South Pole. That maximum extent was 595,000 square miles above the 1981-2010 average extent, the NSIDC...
'Plumbing System' Slows Greenland Ice Sheet
2014-10-07 00:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: The subglacial "plumbing system" beneath Greenland is slowing the ice sheet's movement toward the sea as the summer progresses, according to new research. "Everyone wants to know what's happening under Greenland as it experiences more and more melt," study co-author Ginny Catania, a research scientist at the University of Texas at Austin's Institute for Geophysics, said in a statement. "This subglacial plumbing may or may not be critical for sea level rise in the next 100 years, but we don't really...

Melting ice leaves 35000 walrus stranded in Alaska - is climate change to blame?
2014-10-05 18:09:00| Climate Ark Climate Change & Global Warming Newsfeed
Mirror: This enormous gathering of walrus has been spotted off the coast of Alaska, sparking fears that climate change could be to blame. An estimated 35,000 walrus have been seen five miles north of Point Lay, according to the National Oceanic and Atmospheric Administration. It is thought the animals have been forced onto the beach because they cannot find any sea ice to rest on, due to rising temperatures. Margaret Williams managing director of WWFs Arctic programme, said: "The massive concentration...
