Latest Retreat of glaciers since Stories

2012-07-30 13:49:09

After the fall of the Soviet Union twenty years ago, water distribution in Central Asia became a source of conflict. In areas where summer precipitation is low, glaciers play an important role when considering the quantity of available water. The Tien Shan region is a prime example; mountain glaciers in this region contribute significantly to the fresh water supply in the arid zones of Kyrgyzstan, Kazakhstan, Uzbekistan, Turkmenistan, and Northwestern China. Like Switzerland, Kyrgyzstan...

80-Year-Old Photos Aid In Greenland Ice Melt Study
2012-05-30 09:11:47

Researchers from Denmark´s University of Copenhagen have gained new insight into the loss of ice mass in Greenland´s glaciers thanks to a chance discovery of 80-year-old photo plates discovered in a Danish basement. It is often difficult for scientists to assess the scale and speed of Arctic ice melt, but the extremely rare photos provide them with a more accurate picture. Greenland´s ice was rapidly melting in the 1930s, followed by a cooling period in middle of the 20th...

Greenland Glacier Acceleration Levels Less Than Originally Feared
2012-05-04 06:55:11

Some of Greenland's glaciers are moving approximately 30% faster than they were a decade ago, contributing to the rising sea level but not reaching worst-case speed levels that experts once feared, a new study published in Friday's edition of the journal Science has discovered. According to Reuters reporter Deborah Zabarenko, researchers at the University of Washington (UW) and Ohio State University (OSU) studied satellite data from 2000 to 2011. They focused on more than 200 glaciers and...

State Of Himalayan Glaciers Less Alarming Than Feared
2012-04-20 08:21:58

Ever since the false prognoses of the Intergovernmental Panel on Climate Change (IPCC), the Himalayan glaciers have been a focus of public and scientific debate. The gaps in our knowledge of glaciers in the Himalayan region have hindered accurate statements and prognoses. An international team of researchers headed by glaciologists from the University of Zurich and with the involvement of scientists from Geneva now outlines the current state of knowledge of glaciers in the Himalayas in a...

Image 1 - West Antarctic Ice Shelves Tearing Apart at the Seams
2012-03-28 04:31:05

[ Watch the Video ] A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an already accelerating loss of ice to the sea. The most extensive record yet of the evolution of the floating ice shelves in the eastern Amundsen Sea Embayment in West Antarctica shows that their margins, where they grip onto rocky bay walls or...

The composition of land surface — such as vegetation type and land use — regulates the interaction of radiation, sensible heat and humidity between the land surface and the atmosphere and, thus, influences ground level climate directly. For the first time, the Innsbruck climate scientists quantitatively examined whether land-cover changes (LCC) may potentially affect glacier loss. "We used Kilimanjaro in East Africa as a test case, where a significant decrease of forests at...

Retreating glaciers threaten water supplies Glaciers are retreating at an unexpectedly fast rate according to research done in Peru's Cordillera Blanca by McGill doctoral student Michel Baraer. They are currently shrinking by about one per cent a year, and that percentage is increasing steadily, according to his calculations. But despite this accelerated glacial shrinking, for the first time, the volume of water draining from the glacier into the Rio Santa in Northern Peru has started...

French Alps Glaciers Have Decreased 26% In 40 Years
2011-12-08 06:18:02

A new study has found that the glaciers in the French Alps have lost a quarter of their area in the past 40 years. Marie Gardent, from the University of Savoie, and colleagues assessed about 600 glaciers in broad areas incorporating the Ecrins, Belledonne, Vanoise, Ubaye and Grande Rousse Arves massifs. The team used map archives, past satellite imagery and aerial photographs to assess the areas.  Manual inspection was used to ensure that the automatic delineation methods used in...

Findings from the most comprehensive assessment to date on climate change, snow and glacier melt in Asia's mountainous Hindu Kush-Himalayan (HKH) region -- site of Mount Everest and many of the world's tallest peaks -- highlight the region's extreme vulnerability to climate change, as rising temperatures disturb the balance of snow, ice and water, threatening millions of mountain people and 1.3 billion people living downstream in Asia's major river basins. The findings, published in three...

Researchers To Drill Beneath Massive Antarctic Ice Shelf
2011-11-10 04:49:24

[ Watch the Video ] An international team of researchers funded by NASA and the National Science Foundation (NSF) will travel next month to one of Antarctica's most active, remote and harsh spots to determine how changes in the waters circulating under an active ice sheet are causing a glacier to accelerate and drain into the sea. The science expedition will be the most extensive ever deployed to Pine Island Glacier. It is the area of the ice-covered continent that concerns scientists...
