Study: Alpine glaciers may nearly vanish

Apr 04 ,Space & Earth science


The World Glacier Monitoring Service is warning Europe's Alps might lose three-quarters of its glaciers to global warming during the coming century.

Scientists at the Zurich-based service say they base their conclusion on forecasts of temperature and precipitation changes in a new computer model of Alpine glaciation, the BBC reported Tuesday.

The Consultative Body on Climate Changes, a national Swiss scientific organization based in Berne, reportedly says summers are likely to become warmer by about 3C before the end of the century, and precipitation is likely to increase by about 10 percent.

Across the Alps, that would mean a loss of approximately 75 percent in the glaciated area, researchers told the BBC.

Scientists note glaciers are crucial in providing fresh drinking water, as well as important for tourism, irrigation and hydro-power.

Global warming is causing major shifts in the range of small mammals in Yosemite National Park, one of the nation's treasures that was set aside as a public trust 144 years ago, according to a new study by University of California, Berkeley, biologists.
Patagonian glacier yields clues for improved understanding of global climate change
Although ice cores obtained from Antarctica have now provided more than 800 000 years’ worth of climate records, analysis of them alone is insufficient for understanding the history of climatic interactions between the diverse regions of the world. Boreholes drilled during the 1990s on six glaciers in the tropical zone of the Andean Cordillera gave rise to a substantial collection of data on the changes and developments of the tropical climate of the Southern Hemisphere.

Cave records provide clues to climate change
When Georgia Tech Assistant Professor Kim Cobb and graduate student Jud Partin wanted to understand the mechanisms that drove the abrupt climate change events that occurred thousands of years ago, they didn't drill for ice cores from the glaciers of Greenland or the icy plains of Antarctica, as is customary for paleoclimatolgists. Instead, they went underground.

The "snows" of Africa's Mount Kilimanjaro inspired the title of an iconic American short story, but now its dwindling icecap is being cited as proof for human-induced global warming.
Permanent ice fields are resisting global warming
The small ice caps of Mont Blanc and the Dôme du Goûter are not melting, or at least, not yet. This is what CNRS researchers have announced in the Journal of Geophysical Research. At very high altitudes (above 4200 meters), the accumulation of snow and ice has varied very little since the beginning of the 20th century. But if summer temperatures increase by a few degrees during the 21st century, the melt could become more marked, and could affect the "permanent" ice fields.
Climate predictions grim, but no surprise
Climate change will wipe out 20 to 30 per cent of all life forms and flood hundreds of millions of people from their homes, according to early reports from a new study by the UN's Intergovernmental Panel on Climate Change.
Gravity Measurements Help Melt Ice Mysteries
Greenland is cold and hot. It's a deep freezer storing 10 percent of Earth's ice and a subject of fevered debate. If something should melt all that ice, global sea level could rise as much as 7 meters (23 feet). Greenland and Antarctica - Earth's two biggest icehouses - are important indicators of climate change and a high priority for research, as highlighted by the newly inaugurated International Polar Year.
