Glaciers rapidly shrinking and disappearing: 50 years of glacier change in Montana
The warming climate has dramatically reduced the size of 39 glaciers in Montana since 1966, some by as much as 85 percent, according to data released by the U.S. Geological Survey and Portland State University. On average, the glaciers have reduced by 39 percent and only 26 glaciers are now larger than 25 acres, which is used as a guideline for deciding if bodies of ice are large enough to be considered glaciers.

Quirky glacial behavior explained
In August 2012, the Jakobshavn Glacier was flowing and breaking off into the sea at record speeds, three times faster than in previous years. As the glacier flowed faster, it became thinner and more unstable and in a twist, a pileup of thick ice replenished the glacier's terminus, slowing it down again. New work explaining the fast-then-slow movement of Jakobshavn may help scientists better predict how tidewater glaciers contribute to sea level rise. (2018-11-29)

Scientists pioneer method to track water flowing through glaciers
Researchers for the first time have used seismic sensors to track meltwater flowing through glaciers and into the ocean, a critical step to understanding glaciers as climate changes. Meltwater moving through a glacier can increase melting and destabilize the glacier. It can speed the glacier's flow downhill. It can move boulders and other sediments toward the terminus of the glacier. And it can churn warm ocean water and bring it in contact with the glacier. (2015-08-10)

A glacier's life
Ecole Polytechnique Federale de Lausanne researchers have developed a numerical model that can re-create the state of Switzerland's Rhône Glacier as it was in 1874 and predict its evolution until the year 2100. This is the longest period of time ever modeled in the life of a glacier, involving complex data analysis and mathematical techniques. The work will serve as a benchmark study for those interested in the state of glaciers and their relation to climate change. (2008-10-29)

Antarctic ice loss
Professor Jonathan Bamber at the University of Bristol and colleagues estimated the flux of ice from the ice sheet into the ocean from satellite data that cover 85 percent of Antarctica's coastline. They arrived at a best estimate of a loss of 132 billion tons of ice in 2006 from West Antarctica -- up from about 83 billion tons in 1996 -- and a loss of about 60 billion tons in 2006 from the Antarctic Peninsula. (2008-01-13)

Global glacier melt continues
Glaciers around the globe continue to melt at high rates. Tentative figures for the year 2007, of the World Glacier Monitoring Service at the University of Zurich, Switzerland, indicate a further loss of average ice thickness of roughly 0.67 meter water equivalent (m w.e.). Some glaciers in the European Alps lost up to 2.5 m w.e. (2009-01-29)

With supercooling and the right geometry, 'warm' glaciers can trap and transport silt
A riddle that has long baffled geologists -- how some glaciers trap and transport silt -- is explained by a team of geologists in the Aug. 14 issue of Nature magazine. Led by Edward B. Evenson of Lehigh University, the geologists conducted a 12-year study of the Matanuska Glacier in Alaska, where they found that supercooled water re-freezes onto the bottom of the glacier, forming tiny crystals of ice that act like filters. (2003-08-14)

Shrinking of Greenland's glaciers began accelerating in 2000, research finds
Satellite data has given scientists clues about how, when and why Greenland's glaciers are shrinking -- and shows a sharp increase in glacial retreat beginning about 2000, according to new research presented this week. (2019-12-11)

Glaciers melt faster than ever
Glacier decline in the first decade of the 21st century has reached a historical record, since the onset of direct observations.
