Warming Revives Dream of Sea Route in Russian Arctic

The New York Times, October 17, 2011

ARKHANGELSK, Russia — Rounding the northernmost tip of Russia in his oceangoing tugboat this summer, Capt. Vladimir V. Bozanov saw plenty of walruses, some pods of beluga whales and in the distance a few icebergs. With an icebreaker leading the way, the Vladimir Tikhonov, carrying gas condensate, passed Cape Dezhnev in late August.
One thing Captain Bozanov did not encounter while towing an industrial barge 2,300 miles across the Arctic Ocean was solid ice blocking his path anywhere along the route. Ten years ago, he said, an ice-free passage, even at the peak of summer, was exceptionally rare.But environmental scientists say there is now no doubt that global warming is shrinking the Arctic ice pack, opening new sea lanes and making the few previously navigable routes near shore accessible more months of the year. And whatever the grim environmental repercussions of greenhouse gas, companies in Russia and other countries around the Arctic Ocean are mining that dark cloud’s silver lining by finding new opportunities for commerce and trade.Read more...

News at the North Pole Ozone Layer

ENN, March 16, 2011

Unusually low temperatures in the Arctic ozone layer have recently initiated massive ozone depletion. The Arctic appears to be heading for a record loss of this trace gas that protects the Earth's surface against ultraviolet radiation from the sun. This result has been found by measurements carried out by an international network of over 30 ozone sounding stations spread all over the Arctic and Subarctic and coordinated by the Potsdam Research Unit of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association in Germany.

Arctic Roamers: The Move of Southern Species into Far North

Yale 360, February 14, 2011


Grizzly bears mating with polar bears. Red foxes out-competing Arctic foxes. Exotic diseases making their way into once-isolated polar realms. These are just some of the worrisome phenomena now occurring as Arctic temperatures soar and the Arctic Ocean, a once-impermeable barrier, melts. Read more...

Environment pushes EU to become Arctic player


EuraActiv, November 24, 2008

The European Union on 20 November announced its intention to become an important stakeholder in the Arctic, mainly by promoting an environmental agenda. The European Commission also indicated that Arctic multilateral governance "could be upgraded and adjusted" to changing realities.
The Commission has decided to apply for observer status in the Arctic Council, an intergovernmental forum for countries and peoples, including the Arctic indigenous communities. Read more...

Arctic summers ice-free 'by 2013'


BBC News, December 12, 2007
By Jonathan Amos Science reporter, BBC News, San Francisco

Scientists in the US have presented one of the most dramatic forecasts yet for the disappearance of Arctic sea ice. Their latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years.
Professor Wieslaw Maslowski told an American Geophysical Union meeting that previous projections had underestimated the processes now driving ice loss. Summer melting this year reduced the ice cover to 4.13 million sq km, the smallest ever extent in modern times. Read more...
