ScienceDaily (Feb. 12, 2010) — Depicting a cause-and-effect scenario that spans thousands of miles, a scientist at Scripps Institution of Oceanography at UC San Diego and his collaborators discovered that ocean waves originating along the Pacific coasts of North and South America impact Antarctic ice shelves and could play a role in their catastrophic collapse. […]
By Staff WritersParis (AFP) Feb 7, 2010 A drought that has gripped the southwestern corner of Australia since the 1970s is linked with higher snowfall in East Antarctica, a phenomenon that may be rooted in global warming, scientists reported on Sunday. Researchers Tas van Ommen and Vin Morgan of the Australian Antarctic Division said that […]
By Keith Farnish and Dmitry Orlov …In Part I of this series, just a couple of months ago, we cheerfully wrote: “The East Antarctic Ice Sheet (that’s the big blob that surrounds the South Pole just off-centre) seems to be quite stable, and should remain that way for the next few centuries.” That would have […]
The continent of Antarctica has been losing more than 100 cubic kilometers (24 cubic miles) of ice per year since 2002. Measurements from the Grace satellites confirm that Antarctica is losing mass 11. Isabella Velicogna of JPL and the University of California, Irvine, uses Grace data to weigh the Antarctic ice sheet from space. Her […]
Seas were nearly 10 metres higher than now in previous interglacial period. By Richard A. Lovett With climate talks stalling in Copenhagen, a study suggests that one problem, sea level rise, may be even more urgent than previously thought. Robert Kopp, a palaeoclimatologist at Princeton University in New Jersey, and his colleagues examined sea level […]
A review of climate change in Antarctica forecasts that by 2100 the world’s seas will have risen to levels previously considered too extreme to be realistic. The review, Antarctic Climate Change and the Environment [pdf], was compiled by 100 scientists associated with the international Scientific Committee on Antarctic Research. Using 20 of the most […]
East Antarctic sheet shedding 57bn tonnes of ice a year and contributing to sea level rises, according to NASA aerial survey By Ian Sample, science correspondentwww.guardian.co.uk, Sunday 22 November 2009 18.00 GMT The world’s largest ice sheet has started to melt along its coastal fringes, raising fears that global sea levels will rise faster than […]
Sea levels could rise by up to six metres if the world fails to get pollution under control according to the latest study in the Antarctic. By Louise Gray, Environment CorrespondentPublished: 1:56PM GMT 18 Nov 2009 The British Antarctic Survey found that during past periods of high carbon dioxide, temperatures in Antarctica were up […]
By ANDREW DARBYNovember 7, 2009 HOBART: The Rudd Government has pulled plans to publicise the discovery of massive illegal fishing nets in the Antarctic while the ship that found them, Oceanic Viking, is under a different spotlight. Bottom-set gillnets are presenting a new crisis in Australia’s regional waters. Laid by foreign fishers, they form a […]
Change measurements are median filtered (10-km radius), spatially averaged (5-km radius) and gridded to 3 km, from intervals (Dt) of at least 365 d, over the period 2003–2007 (mean Dt is 728 d for Antarctica and 746 d for Greenland). East Antarctic data cropped to 2,500-m altitude. White dashed line (at 81.5° S) shows southern […]
