The ~250 square km Petermann floating ice “island” has drifted into Nares St. The drift out of Petermann fjord has been slow, as tides wash in and out and the berg was jammed in the fjord 20-25 August. Prevailing winds blowing toward the south will push the berg in that direction. Petermann Ice Island drifts […]
By THOMAS HOMER-DIXON, Aboard the Louis S. St-LaurentAugust 22, 2010 STANDING on the deck of this floating laboratory for Arctic science, which is part of Canada’s Coast Guard fleet and one of the world’s most powerful icebreakers, I can see vivid evidence of climate change. Channels through the Canadian Arctic archipelago that were choked with […]
By Jason Box with assistance from David Decker The recent ice island detachment at Petermann glacier is part of a larger pattern of deglaciation observed at 31/34 glaciers (91%) in our survey. We just updated our survey to include year 2010. Retreat continues at the 110 km (68 mi) wide Humboldt glacier and at the […]
The Greenland ice sheet is melting at a record rate due to global warming, according to a British-led expedition currently taking measurements from the treacherous glaciers. By Louise Gray, Environment CorrespondentPublished: 7:00AM BST 13 Aug 2010 The University of St Andrews team said 106 square miles broke away from the Petermann Glacier at the beginning […]
Last updated: 11 August 2010 Several regions of the world are currently coping with severe weather-related events: flash floods and widespread flooding in large parts of Asia and parts of Central Europe while other regions are also affected: by heatwave and drought in Russian Federation, mudslides in China and severe droughts in sub-Saharan Africa. While […]
BBC6 August 2010 A giant sheet of ice measuring 260 sq km (100 sq miles) has broken off a glacier in Greenland, according to researchers at a US university. The block of ice separated from the Petermann Glacier, on the north-west coast of Greenland. It is the largest Arctic iceberg to calve since 1962, […]
Jakobshavn Glacier, 14 July 2001 Jakobshavn Glacier, 10 July 2010 For most of the past century, the Jakobshavn Glacier, or Jakobshavn Isbræ, along the west coast of Greenland has extended out into the ocean as a long, narrow ice tongue. The glacier drains a large portion of Greenland’s ice sheet, and consequently, the […]
NASA-funded researchers monitoring Greenland’s Jakobshavn Isbrae glacier report that a 7 square kilometer (2.7 square mile) section of the glacier broke up on July 6 and 7, as shown in the image above. The calving front – where the ice sheet meets the ocean – retreated nearly 1.5 kilometers (a mile) in one day and […]
Our 2009 area change survey of 34 of the widest Greenland marine-terminating glacier outlets from the inland ice sheet is complete. We find a net marine-terminating ice area loss of 109 sq km. The total net cumulative area change from year 2000 (when our survey begins) to 2009 is -990.2 sq. km, a loss equivalent […]
ScienceDaily (May 18, 2010) — Greenland is situated in the Atlantic Ocean to the northeast of Canada. It has stunning fjords on its rocky coast formed by moving glaciers, and a dense icecap up to 2 km thick that covers much of the island–pressing down the land beneath and lowering its elevation. Now, scientists […]
