In Himalayas rocks buffer retreat of glaciers

Ever since the Intergovernmental Panel on Climate Change erroneously reported that the Himalaya mountains would be glacier-free by 2035, the actual fate of the world’s highest range has been questioned. An accurate picture has been hard to develop because of differences in retreat rates and a lack of basic data on the glaciers. One study published this week in the journal Nature Geoscience sheds some new light on mountaintop glacial dynamics in the Himalayas. Lead author Dirk Scherler from... [Read more]

Frigid mountain glaciers prevent erosion

Glaciers are well known shapers of the landscape as they advance and recede through the ice ages. In the U.S. we even have Glacier National Park named after the work of glaciers, which carved out huge valleys and lakes and sculpted the dramatic mountains, which have exposed the finest fossilized examples of extremely early life found anywhere on Earth. As we all know, glaciers are in trouble. At the Montana Park, only 25 glaciers remain in 2010 of an estimated 150 that existed in the mid 1800s, and... [Read more]

Where ice meets sea

How fast can a glacier melt? Usually the answer is attributed to the amount of warming or CO2 level rise. But researchers are also looking into the actual mechanics of glacier melt to get a handle on what’s causing ice to wear away. In a paper published recently in Nature Geoscience, Adrian Jenkins of the British Antarctic Survey and colleagues examined Pine Island Glacier, one of the two main contributors of ice loss in West Antarctica.
