Study links polar vortex chills to sea ice
2014-09-03 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: Remember the polar vortex, the huge mass of Arctic air that can plunge much of the U.S. into the deep freeze? You might have to get used to it. A new study says that as the world gets warmer, parts of North America, Europe and Asia could see more frequent and stronger visits of that cold air. Researchers say that's because of shrinking ice in the seas off Russia. Normally, the polar vortex is penned in the Arctic. But at times it escapes and wanders south, bringing with it a bit of Arctic super...

Time for a wake-up call on polar bears
2014-08-15 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Arctic Journal: What happens when natures sea bear is forced ashore? That question is being looked into by Colorado State University scientists as they seek to identify the effects of global warming on polar bears, whose Latin name Ursus marinus indicates that they spend much of their time at sea hunting seals. Arctic sea ice, however, is in a period of rapid decline and that is increasingly pushing polar bears onto dry land. Some studies have shown that they are adaptable to life on land; if a lack of...
