Sea Ice (Page 4)
Research yields better seasonal climate forecastsScienceDaily.com | 13 Feb 2012
Arctic sea ice is rapidly retreating. Within a few decades the North Pole could be completely ice-free in summer. How will that affect our weather? In the research project "Seasonal Predictability over the Arctic Region" (SPAR), scientists in Norway have made some discoveries that may lead to more reliable seasonal forecasts.
Canadian seal cull 'unnecessary due to climate change'Guardian Unlimited | 06 Jan 2012
Canada faced fresh calls to shut down its commercial seal hunt on Thursday, following new evidence that death rates among seal pups had dramatically increased due to thinning winter sea ice.
Arctic sea ice continues decline, hits second-lowest levelScienceDaily.com | 05 Oct 2011
Last month the extent of sea ice covering the Arctic Ocean declined to the second-lowest extent on record. Satellite data from NASA and the the National Snow and Ice Data Center showed that the summertime sea ice cover narrowly avoided a new record low. The near-record ice-melt followed higher-than-average summer temperatures, but without the unusual weather conditions that contributed to the extreme melt of 2007.
Melting ice is Earth's warning signal - and we cannot ignore itGuardian Unlimited | 24 Sep 2011
Ice is the white flag being waved by our planet, under fire from the atmospheric attack being mounted by humanity. From the frosted plains of the Arctic ice pack to the cool blue caverns of the mountain glaciers, the dripping away of frozen water is the most crystal clear of all the Earth's warning signals.
The reversibility of sea ice loss in a state-of-the-art climate modelAmerican Geophysical Union | 23 Sep 2011
Rapid Arctic sea ice retreat has fueled speculation about the possibility of threshold (or tipping point) behavior and irreversible loss of the sea ice cover. We test sea ice reversibility within a state-of-the-art atmosphere–ocean global climate model by increasing atmospheric carbon dioxide until the Arctic Ocean becomes ice-free throughout the year and subsequently decreasing it until the initial ice cover returns.
Summer Arctic sea ice melt at or near recordReuters | 13 Sep 2011
LONDON (Reuters) - Arctic sea ice this summer melted to a record low extent or will come a close second, two different research institutes said on Tuesday, confirming a trend which could yield an ice-free summer within a decade.
Arctic sea ice is melting at its fastest pace in almost 40 yearsGuardian Unlimited | 11 Sep 2011
The Northwest Passage was, again, free of ice this summer and the polar region could be unfrozen in just 30 years Arctic sea ice has melted to a level not recorded since satellite observations started in 1972 - and almost certainly not experienced for at least 8,000 years, say polar scientists.
Witness: Arctic ice breaks up as polar bears stalk shipReuters | 07 Sep 2011
500 MILES FROM THE NORTH POLE (Reuters) - Stepping onto an Arctic ice floe on Monday, an unusually mild, easterly breeze blew at the end of the annual summer melt. The footprints of two polar bears from the night before were disintegrating in a dusting of snow.
Experts drill Arctic ice to fathom speed of meltReuters | 07 Sep 2011
500 MILES OFF THE NORTH POLE (Reuters) - As polar bears stalked their ship, scientists drilled into the Arctic sea ice this week to try and figure out why it's disappearing so fast.
Total Arctic sea ice at record low in 2010: studyReuters | 05 Sep 2011
500 MILES FROM THE NORTH POLE (Reuters) - The minimum summertime volume of Arctic sea ice fell to a record low last year, researchers said in a study to be published shortly, suggesting that thinning of the ice had outweighed a recovery in area.
Rowers first to reach magnetic North PoleNew Zealand Herald | 28 Aug 2011
A six-man British crew have become the first to row to the magnetic North Pole, completing the 725km journey from northern Canada in under four weeks. Crew leader Jock Wishart undertook the expedition to highlight climate change in the Arctic region.
Pacific walruses studied as sea ice meltsScienceDaily.com | 25 Aug 2011
U.S. Geological Survey Alaska Science Center researchers, in cooperation with the Native Village of Point Lay, will attempt to attach 35 satellite radio-tags to walruses on the northwestern Alaska coast in August as part of their ongoing study of how the Pacific walrus are responding to reduced sea ice conditions in late summer and fall.
