Contact: Janet Lathrop, 413-545-044421 June 2012 AMHERST, Massachusetts – First analyses of the longest sediment core ever collected on land in the terrestrial Arctic, published this week in Science, provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years. (“2.8 Million Years of Arctic Climate Change […]
By James Astill16 June 2012 STANDING ON THE Greenland ice cap, it is obvious why restless modern man so reveres wild places. Everywhere you look, ice draws the eye, squeezed and chiselled by a unique coincidence of forces. Gormenghastian ice ridges, silver and lapis blue, ice mounds and other frozen contortions are minutely observable in […]
By Roberto Cortijo 4 June 2012 Peru needs a permanent monitoring system to gauge Andean mountain glacier shrinkage caused by global warming and its effect on people who depend on the ice for water, UN experts warned. “We have spoken with Peruvian government institutions, and there is no sufficient monitoring system to tell us the […]
[But see What makes sea-level rise?] By Damian Carrington, www.guardian.co.uk 20 May 2012 Humanity’s unquenchable thirst for fresh water is driving up sea levels even faster than melting glaciers, according to new research. The massive impact of the global population’s growing need for water on rising sea levels is revealed in a comprehensive assessment of […]
By Richard Black, Environment correspondent, BBC News20 May 2012 Scientists have identified thousands of sites in the Arctic where methane that has been stored for many millennia is bubbling into the atmosphere. The methane has been trapped by ice, but is able to escape as the ice melts. Writing in the journal Nature Geoscience, the […]
By Chris Wickham; Editing by Janet Lawrence9 May 2012 LONDON (Reuters) – Scientists are predicting the disappearance of another vast ice shelf in Antarctica by the end of the century that will accelerate rising sea levels. The Filchner-Ronne Ice Shelf fringing the Weddell Sea on the eastern side of Antarctica has so far not seen […]
Outlet glacier categories and rates of velocity change (percentage change from beginning of 5-year period). Black-outlined images show 2000 to 2005 results, and red-outlined images are 2005 to 2010 results. The background velocity map for both periods is a 2007 to 2010 composite, with the five ice-sheet regions indicated: north (N), northwest (NW), southwest (SW), […]
By Tamera Jones4 May 2012 Scientists have long been concerned that the massive West Antarctic Ice Sheet could collapse if global temperatures keep climbing. If it did, sea levels are predicted to rise by as much as five metres. Now, genetic evidence from an Antarctic octopus reveals that this may have happened at some point […]
By Damian Carrington, www.guardian.co.uk 3 May 2012 Sea-level rises are unlikely to be as high as worst-case scenarios have forecasted, suggests new research which shows that Greenland‘s glaciers are slipping into the sea more slowly than was previously thought. But the scientists warned that ice loss still sped up by 30% and is driving rises […]
By Jonathan Bamber, www.guardian.co.uk 15 April 2012 Glaciers are one of the natural environments most often used to illustrate the impacts of climate change. It is fairly indisputable that in a warming world, glaciers melt faster. Yet two recent studies published in top scientific journals (more here and here) suggest that in the Himalayas the […]
