Cryospheric science: Asia’s glacier changes
Nature Geoscience 10, 621 (2017). doi:10.1038/ngeo2995 Author: Daniel Farinotti Mass changes in High Mountain Asia’s glaciers have been under dispute for almost a decade. An analysis of satellite data archives provides an observation-based mass budget for every single glacier in … Continue reading

NASA has captured new mysterious crack on the Greenland’s largest glacier
An aerial view of a chasm running through an ice shelf. The first photographs of a new and ominous crack in Greenland’s enormous Petermann Glacier were captured by a NASA airborne mission Friday. NASA’s Operation IceBridge, which has been flying … Continue reading
Retreating Yukon glacier caused a river to disappear
A postmortem of the first known case of ‘river piracy’ in modern times outlines how a retreating glacier in the Yukon diverted water from one river to another, leading to many downstream effects. Geology News — ScienceDaily
Large hidden lakes found draining below Antarctic glacier
Part of the Thwaites Glacier on the edge of West Antarctica. Thwaites Glacier on the edge of West Antarctica is one of the planet’s fastest-moving glaciers. Research shows that it is sliding unstoppably into the ocean, mainly due to warmer … Continue reading

Geologic formation could hold clues to melting glacier floodwaters
Geologists investigating an unusual landform in the Wabash River Valley in southern Illinois expected to find seismic origins, but instead found the aftermath of rushing floodwaters from melting Midwestern glaciers after the last ice age. The finding could give clues … Continue reading
Ancient pollen reveals droughts between Sierra Nevada glacier surges
Hidden below the surface of California’s Central Valley are pollen grains from the Pleistocene that are providing scientists with clues to the severity of droughts that struck the region between glacial periods. Paleontology News — ScienceDaily
