Researchers find major West Antarctic glacier melting from geothermal sources
Thwaites Glacier, the large, rapidly changing outlet of the West Antarctic Ice Sheet, is not only being eroded by the ocean, it's being melted from below by geothermal heat, researchers at the Institute for ...
Krypton used to accurately date ancient Antarctic ice
A team of scientists has successfully identified the age of 120,000-year-old Antarctic ice using radiometric krypton dating – a new technique that may allow them to locate and date ice that is more than ...
Soot suspect in puzzling mid-1800s Alps glacier retreat
Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps.
Researchers find 400 year old Ice Age plants in Arctic able to grow anew as glaciers retreat
One-third of sea level rise comes from melting mountain glaciers, study reports
While 99 percent of Earth's land ice is locked up in the Greenland and Antarctic ice sheets, the remaining ice in the world's glaciers contributed just as much to sea rise as the two ice sheets combined from ...
Researchers analyzing hyrax urine layers to study climate change
How fast can glaciers respond to climate change?
A new Arctic study in the journal Science is helping to unravel an important mystery surrounding climate change: How quickly glaciers can melt and grow in response to shifts in temperature.
New satellite data on melting of Himalayan glaciers
Researchers say habitat loss and tropical cooling were to blame for mass extinction
(Phys.org) -- The second-largest mass extinction in Earth's history coincided with a short but intense ice age during which enormous glaciers grew and sea levels dropped. Although it has long been agreed that ...
Hearty bacteria help make case for life in the extreme
(PhysOrg.com) -- The bottom of a glacier is not the most hospitable place on Earth, but at least two types of bacteria happily live there, according to researchers.
Warming ocean layers will undermine polar ice sheets
Warming of the ocean's subsurface layers will melt underwater portions of the Greenland and Antarctic ice sheets faster than previously thought, according to new University of Arizona-led research. Such melting ...
Ocean currents speed melting of Antarctic ice
Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience. A grow ...
New map reveals giant fjords beneath East Antarctic ice sheet
Scientists from the U.S., U.K. and Australia have used ice-penetrating radar to create the first high- resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, ...
Melting ice on Arctic islands a major player in sea level rise
Melting glaciers and ice caps on Canadian Arctic islands play a much greater role in sea level rise than scientists previously thought, according to a new study led by a University of Michigan researcher.
