'Within decade, Arctic Ocean will be ice-free each summer'October 15th, 2009 LONDON - The ice cover over the Arctic Ocean is continuing to get thinner, according to new data released here Thursday, which supports the theory that due to global warming the ocean will be largely ice-free in summer within a decade. The Catlin Arctic Survey, completed earlier this year, provides the latest ice thickness record.
Arctic could be ice-free in as little as ten years' timeOctober 15th, 2009 LONDON - A top Polar specialist has warned that the Arctic Ocean could be largely ice-free and open to shipping during the summer in as little as ten years' time. "It's like man is taking the lid off the northern part of the planet," Professor Peter Wadhams, from the University of Cambridge, told BBC News.
Extent of Arctic Sea ice is third lowest on recordOctober 7th, 2009 WASHINGTON - The extent of the Arctic Sea ice this year or the area covered by floating ice was the third lowest since satellite measurements were first made in 1979. The ice area at minimum was an increase from the past two years, but still well below the average for the past 30 years.
Arctic ice to last until 2030 to 2040September 22nd, 2009 WASHINGTON - New findings by scientists indicate that that Arctic ice would last decades longer than thought, and the region won't experience ice-free summers until 2030 or 2040. Some models had previously predicted that the Arctic could be ice free in summer by as soon as 2013, due to rising temperatures from global warming.
Arctic sea ice cover reaches minimum extent for 2009September 18th, 2009 WASHINGTON - A new study has found that the Arctic sea ice cover appears to have reached its minimum extent for this year, the third-lowest recorded since satellites began measuring sea ice extent in 1979. The study was carried out by researchers from to the University of Colorado at Boulder's National Snow and Ice Data Center.
Sea ice melting in Arctic remains far worse than normal, but only ranks No. 3 in record booksSeptember 17th, 2009 Arctic sea ice melt still heavy, but no recordWASHINGTON — The summer melt of Arctic sea ice wasn't quite as bad this year as the last two years. But it still ranked as the third biggest melt on record.
Petition advances to list walrus as endangered due to warming, loss of sea iceSeptember 8th, 2009 Federal agency advances walrus listing petitionANCHORAGE, Alaska — A second Arctic marine mammal moved closer to an Endangered Species listing due to global warming Tuesday with a petition to grant the Pacific walrus protection passing its first review. The U.S. Fish and Wildlife Service announced that a petition presented by the Center for Biological Diversity provided substantial information that listing the walrus as threatened or endangered was warranted.
NASA spacecraft reveals dramatic thinning of Arctic sea iceJuly 8th, 2009 WASHINGTON - Data from a NASA Earth-orbiting spacecraft has revealed a dramatic thinning of Arctic sea ice between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record. The new results provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover.
Scientists see dramatic increase in amount of fresh water in Arctic OceanJuly 5th, 2009 WASHINGTON - A new study by scientists has shown a dramatic increase in the amount of fresh water in the Arctic Ocean. Fresh water flowing into or out of the Arctic Ocean plays an important role in ocean circulation and may be a factor in the response of the world ocean to climate change.
The Arctic was an enclosed freshwater lake until about 38 million years agoJuly 5th, 2009 WASHINGTON - An analysis by scientists has suggested that the Arctic was an enclosed freshwater lake until about 38 million years ago, when tectonic activity caused it to undergo a transition to an ocean. Recent studies have suggested that beginning about 44 million years ago the Arctic underwent a transition from lake to ocean conditions.
Environmentalists plan to sue feds to force decision on listing Arctic seals as endangeredJune 4th, 2009 Environmentalists plan suit to protect ice sealsANCHORAGE, Alaska — An environmental group plans to sue the federal government to force a decision on additional protections for Arctic seals. The Center for Biological Diversity said in a notice of intent to sue sent this week to the National Oceanic and Atmospheric Administration that it missed a deadline required by law for an endangered species listing decision on ringed, bearded and spotted seals.
Mercury levels in Arctic seals may be linked to global warmingMay 4th, 2009 WASHINGTON - In a new study, researchers in Canada are reporting for the first time that high mercury levels in certain Arctic seals appear to be linked to vanishing sea ice caused by global warming. The study, by scientist Gary Stern and his colleagues, provides a new insight into the impact of climate change on Arctic marine life.
Latest satellite imagery shows Arctic teetering on thin iceApril 7th, 2009 WASHINGTON - Latest satellite imagery shows that the Arctic is virtually teetering on a layer of thin ice, not to speak of its shrinking ice area over the decade. Researchers from NASA and University of Colorado-Boulder (CUB), who have been tracking Arctic sea ice cover with satellites since 1979, found that the winter of 2008-09 was the fifth lowest maximum ice extent on record.
Arctic literally on thin ice, points out new evidenceApril 7th, 2009 WASHINGTON - New evidence from NASA and satellite observations has shown that the decade-long trend of shrinking sea ice cover in the Arctic is continuing, with the ice cap thinning as well. In recent years, Arctic sea ice has been declining at a surprising rate.
This February was the Earth's ninth warmest since 1880March 17th, 2009 WASHINGTON - The combined land and ocean surface average temperature for February was the ninth warmest since records began in 1880, according to an analysis by National Oceanic and Atmospheric Administration (NOAA). The analysis in NOAA's National Climatic Data Centre (NCDC) global reports are based on preliminary data, which are subject to revision.
