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...

Explorers begin epic Arctic trek


BBC News, March 01, 2009

A British team has begun a gruelling trek to the North Pole to discover how quickly the Arctic sea-ice is melting.
Renowned Arctic explorer Pen Hadow and two companions were dropped onto the ice by plane some 1,700km (670 miles) north of Canada on Saturday night. During their 1,000km journey they plan to take measurements of the thickness of the ice. It will be the most detailed survey of its kind this season, and should be completed in late May.

Slab of Antarctic ice shelf collapses amid warming


ENN, March 26, 2008


WASHINGTON (Reuters) - Satellite images show that a large hunk of Antarctica's Wilkins Ice Shelf has started to collapse in a fast-warming region of the continent, scientists said on Tuesday.
The area of collapse measured about 160 square miles of the Wilkins Ice Shelf, according to satellite imagery from the University of Colorado's National Snow and Ice Data Center. Read more...
