First Cargo Ship To Use The Northwest Passage

First Cargo Ship To Use The Northwest Passage
"How very ironic. Due to global warming, enough of the Arctic ice has melted that cargo ships can navigate the fabled Northwest Passage -- and the first vessel is carrying coal"

Exceptional 2012 Greenland Ice Melt Caused By Jet Stream Changes That May Be Driven By Global Warming

Exceptional 2012 Greenland Ice Melt Caused By Jet Stream Changes That May Be Driven By Global Warming: New research finds that “unusual changes in atmospheric jet stream circulation caused the exceptional surface melt of the Greenland Ice Sheet (GrIS) in summer 2012.” Prof. Jennifer Francis tells me these changes are consistent with those caused by warming-driven “Arctic Amplification.” And that means GrIS may melt faster than climate models have projected. Extent of [...]/p

Canada Vows Plunder in the Arctic | Common Dreams

Canada Vows Plunder in the Arctic | Common Dreams
"Shifting global temperatures and unprecedented melting in the polar region have "boosted international interest," AFP reports, "as melting ice opens up shipping routes and makes hitherto inaccessible mineral resources easier to exploit"."

On Top Of Sea Ice Death Spiral, Ocean Acidification Poised To Radically Alter Arctic

On Top Of Sea Ice Death Spiral, Ocean Acidification Poised To Radically Alter Arctic: The Arctic is the fastest changing place on earth. The most obvious and important change is the staggering loss of sea ice (see “CryoSat-2 Confirms Sea Ice Volume Has Collapsed“). In addition, “the Arctic marine waters are experiencing widespread and rapid ocean acidification,” a new study finds. This first-ever Arctic Ocean Acidification Assessment, commissioned by the Arctic Council’s Arctic Monitoring and Assessment [...]/p

'Off-Limits!': From North Pole, Greenpeace Youth Activists Demand Protection for Arctic | Common Dreams

'Off-Limits!': From North Pole, Greenpeace Youth Activists Demand Protection for Arctic | Common Dreams
"Fulfilling the goal of an ambitious polar adventure, a small Greenpeace team and a group of youth ambassadors have planted a flag on the seabed beneath the North Pole declaring the region "off limits" to exploitation by oil companies, governments, and commercial interests."

Unprecedented Warming in Antarctica Causes Worst Melting in 1,000 Years | Common Dreams

Unprecedented Warming in Antarctica Causes Worst Melting in 1,000 Years | Common Dreams
"Ice is melting at a faster rate in the Antarctic Peninsula than at any time in the past 1000 years, and ten times more than it was 600 years ago, according to a new study by the Australian National University and the British Antarctic Survey, published in Nature Geoscience."

Arctic Sea Ice: The Death Spiral Continues

Arctic Sea Ice: The Death Spiral Continues: The story of the decade is the collapse of Arctic sea ice and its impact on our extreme weather (see “CryoSat-2 Confirms Sea Ice Volume Has Collapsed“). That merits the latest monthly update of sea ice volume by creative tech guru Andy Lee Robinson showing that “death spiral” is the right visual metaphor: Many experts now [...]/p

Scientists Link Harsh Winters to Dramatic Decline in Arctic Ice | Common Dreams

Scientists Link Harsh Winters to Dramatic Decline in Arctic Ice | Common Dreams
"As the Eastern Seaboard of the United States bears the brunt of yet another late season snow storm, a growing body of research proves that the record decline in Arctic sea ice has played a "critical role" in the large and southerly snowfalls of recent years."

How Arctic Ice Loss Amplified Superstorm Sandy — Oceanography Journal

How Arctic Ice Loss Amplified Superstorm Sandy — Oceanography Journal: We’ve written extensively about how global warming worsened the impact of Superstorm Sandy. Now a new article, “Superstorm Sandy: A Series of Unfortunate Events?” (PDF here) connects the dots even more explicitly: Cornell and Rutgers researchers report in the March issue of Oceanography that the severe loss of summertime Arctic sea ice — attributed to [...]/p
