Large Fractures Spotted in Vulnerable Arctic Sea Ice
2013-03-13 21:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Following more than two decades of Arctic sea ice thinning and melting, an unusual event just weeks before the start of the spring melt season is providing visual proof of how vulnerable the ice pack really is. During the end of February and continuing into early March, large fractures in the sea ice were observed off the north coast of Alaska and Canada, from near Ellesmere Island in the Canadian Arctic to Barrow, Ala., the northernmost city in the U.S. The rapid climate change in the Arctic...

Norway's Arctic idyll shivers at oil plans
2013-03-13 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Oil companies seeking new Arctic areas for exploration face a battle with environmentalists, fishermen and hotel owners over Norwegian islands where jagged snow-capped peaks rise sheer from the sea. With oil production falling to a 25-year low this year and the state depending on oil revenues, Norway's ruling Labour Party is warming to drilling in Lofoten's pristine waters, setting up the issue as the year's biggest political fight ahead of elections in September. "We've already got the winning...

Preventing an Arctic cold war
2013-03-13 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: JUST a quarter-century ago, and for millenniums before that, the Arctic Ocean was covered year-round by ice, creating an impregnable wilderness that humans rarely negotiated. Today, as the effects of global warming are amplified in the high north, most of the ocean is open water during the summer and covered by ice only in the winter. This unexpected transformation has radically altered the stakes for the Arctic, especially for the eight nations and indigenous peoples that surround it. But while...

2013-03-12 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: A Chinese shipping firm is planning the country's first commercial voyage through a shortcut across the Arctic Ocean to the United States and Europe in 2013, a leading Chinese scientist said on Tuesday. Huigen Yang, director general of the Polar Research Institute of China, told Reuters that the trip he led last year on the icebreaker Xuelong, or Snowdragon, to explore the route had "greatly encouraged" Chinese shipping companies. "One commercial voyage by a Chinese shipping company may take...

Causes of 2011 Arctic ozone hole determined http://t.co/AmI06Pl8vS
2013-03-11 23:49:00| Climate Ark Climate Change & Global Warming Newsfeed
Science Daily: A combination of extreme cold temperatures, human-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds. Even when both poles of the planet undergo ozone losses during the winter, the Arctic's ozone depletion tends to be milder and shorter-lived than the Antarctic's. This is because the three key ingredients needed for ozone-destroying chemical reactions -- chlorine from human-made chlorofluorocarbons (CFCs), frigid temperatures...
