Like […]
Satellite data of Greenland reflectivity 1-22 June 2012 versus the same periods in previous Junes back to 2000. The blue colors indicate a decrease in reflectivity compared to previous Junes. In a new study, Box and a team of researchers describe the decline in ice sheet reflectivity and the reasons behind it, noting that if […]
By Andrew Freedman29 June 2012 The Greenland ice sheet is poised for another record melt this year, and is approaching a “tipping point” into a new and more dangerous melt regime in which the summer melt area covers the entire land mass, according to new findings from polar researchers. The ice sheet is the focus […]
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 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 […]
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 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 […]
SYDNEY, 13 April 2012 (AFP) – Sea levels in the southwest Pacific started rising drastically in the 1880s, with a notable peak in the 1990s thought to be linked to human-induced climate change, according to a new study. The research, which examined sediment core samples taken from salt marshes in southern Australia’s Tasmania island, used […]
By Michael Marshall, environment reporter9 February 2012 What on Earth is going on with the world’s glaciers? Reports today suggest that the Himalayan glaciers have not lost any [as much –Des] mass in the last decade [as previously thought –Des]. But while that comes as a real surprise, the global pattern remains basically the same. […]
