Andean glaciers melting at 'unprecedented' rates

2013-01-23 12:16:00| Climate Ark Climate Change & Global Warming Newsfeed

Reuters: Climate change has shrunk Andean glaciers between 30 and 50% since the 1970s and could melt many of them away altogether in coming years, according to a study published on Tuesday in the journal Cryosphere. Andean glaciers, a vital source of fresh water for tens of millions of South Americans, are retreating at their fastest rates in more than 300 years, according to the most comprehensive review of Andean ice loss so far. The study included data on about half of all Andean glaciers in South...

Unprecedented Glacial Melting In Andes Blamed On Global Warming

2013-01-22 22:18:00| Climate Ark Climate Change & Global Warming Newsfeed

RedOrbit: Only four months ago and a continent away, researchers were looking into the varying degrees of ice accumulation and ablation within the Himalayan glacial system. In that report, published by the National Research Council (NRC), the team concluded that glacial melt could pose significant issues for the native populations that depend on the water runoff from these glaciers for their day-to-day lives. An international team of scientists from Europe, South America and the U.S. has turned its focus...

Climate change melting glaciers in the Andes

Mongabay: Glaciers are melting faster than ever in the tropical Andes, warns a new study published in The Cryosphere, which puts the blame for vanishing glaciers squarely on climate change. The study - the most comprehensive to date - found that since the 1970s glacier melt in the region has been speeding up, threatening freshwater supplies in Peru and Bolivia. "The ongoing recession of Andean glaciers will become increasingly problematic for regions depending on water resources supplied by glacierised...

[NEWS] Contact: Barbara Ferreira media@egu.eu 49-892-180-6703 European Geosciences Union Glaciers in the tropical Andes have been retreating at increasing rate since the 1970s, scientists write in the most comprehensive review to date of Andean glacier observations. The researchers blame the melting on rising temperatures as the region has warmed about 0.7&#17…

Future sea level rise from melting ice sheets may be substantially greater than IPCC estimates

2013-01-06 21:46:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: Future sea level rise due to the melting of the Greenland and Antarctic ice sheets could be substantially larger than estimated in Climate Change 2007, the Fourth Assessment Report of the IPCC, according to new research from the University of Bristol. The study, published January 6 in Nature Climate Change, is the first of its kind on ice sheet melting to use structured expert elicitation (EE) together with an approach which mathematically pools experts' opinions. EE is already used in a number...
