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 […]
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 Pete Spotts, Staff writer 5 April 2012 Rising levels of carbon dioxide drove much of the global warming that thawed Earth at the end of the last ice age. That’s the conclusion a team of scientists has drawn in a new study examining the factors that closed the door on the last ice age, […]
By Wynne Parry, LiveScience5 April 2012 As a European satellite enters its second decade in orbit, it continues to observe the retreat of an Antarctic ice sheet, which has been dwindling due to warming. The satellite, Envisat, was launched by the European Space Agency (ESA) on March 1, 2002. One of its first observations was […]
By Michael Day in Milan 4 April 2012 With its four steep faces reflecting the compass points, the mighty Matterhorn has proven an irresistible and often deadly challenge to mountaineers. But now, the mountain – one of Europe’s tallest and most celebrated peaks – is falling to bits due to climate change, according to a […]
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. […]
By CAIN BURDEAU, The Associated Press7 February 2012 NEW ORLEANS – A scientific report [Recommendations for Anticipating Sea-Level Rise Impacts on Louisiana Coastal Resources during Project Planning and Design, pdf] issued by Gov. Bobby Jindal’s administration predicts that the Louisiana coast could see about 3 feet of sea level rise along the already low and […]
