Predictions of Arctic summer ice melt come with lots of uncertainty
2014-08-02 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Alaska Dispatch: Every year, as Arctic sea ice thins, scatters and melts, scientists ask: How low will it go? While the long-term trend of less summer Arctic ice is clear, the short-term outlook for total melt in any given year is far murkier, thanks to the many and sometimes highly volatile factors that drive the final outcome. Still, scientists are attempting to predict how much Arctic sea ice will remain at the end of this years melt, expected in mid to late September. The latest round of expert predictions,...
No record, but Arctic sea ice will be among 10 lowest

Climate Central: The extent of sea ice covering the Arctic Ocean at the end of the summer season likely won't surpass the record low of 2012, but 2014 will still likely rank as one of the lowest minimum extents (or areas) in the record books. Arctic sea ice extent for July 15, 2014 was 3.22 million square miles. The orange line shows the 1981 to 2010 average extent for that month. That's according to Julienne Stroeve, a scientist at the National Snow and Ice Data Center in Boulder, Colo. "It's likely that it...
Error identified in satellite record may have overestimated Antarctic sea ice expansion

Guardian: There has been a lot of attention on ice at the southern pole of the Earth. To be clear, the Earths climate is changing and the Earth is getting warmer. This means that the oceans are warming, the atmosphere is warming, sea levels are rising, and ice is melting. In fact, the Earths ice is melting almost everywhere. In the Arctic, sea ice is in a long-term retreat, the Greenland ice sheet is melting, so is the Antarctic ice sheet as are the worlds glaciers. But, there is a perplexing anomaly. The...

16-foot Waves Measured Arctic Ocean Where Once Only Ice
2014-07-31 00:02:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: Sixteen-foot waves are buffeting an area of the Arctic Ocean that until recently was permanently covered in sea ice-another sign of a warming climate, scientists say. Because wave action breaks up sea ice, allowing more sunlight to warm the ocean, it can trigger a cycle that leads to even less ice, more wind, and higher waves. (See "Shrinking Arctic Ice Prompts Drastic Change in National Geographic Atlas.") Scientists had never measured waves in the Beaufort Sea, an area north of Alaska, until...

Scientists begin hi-tech quest for Arctic sea ice answers
2014-07-27 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: An international team of scientists plan to spend months watching ice melt. But although it will take longer and cost a lot more than watching paint dry, it will be much more interesting and rewarding. A sophisticated array of automatic sensors will allow scientists to conduct the longest ever monitoring program to determine the precise physics of summer sea ice melt in the Arctic. They plan to discover just how the Arctic ice retreats, the rate at which it melts, and the oceanographic processes...
