Why the Southern Alps Turned Red During the Summer of 2019-2020
Snow on the Southern Alps turned from white to red in 2019-2020. New geochemical evidence points to the color change resulting from red Australian desert dust carried across the Tasman Sea.
First Global Comparison of Glacier Mass Change: They’re All Melting, and Fast
By systematically assessing data gathered by different methods, researchers refined estimates of global glacier melt and its contribution to sea level rise.
When Ice Ages End, Ocean Circulation Fine-Tunes Ocean Heat
New Antarctic ice core data bolster model predictions of ocean heat content during glacials and interglacials.
Nonlinear Dynamics May Lead to Faster Retreat of Antarctic Ice
The Antarctic ice sheet behaves like a non-Newtonian fluid and may be more nonlinear than previously thought. This impacts its future stability and requires revisions to predictions of sea level rise.
A New 3D Map Shows Precipitous Decline of Ugandan Glaciers
A team of dozens spent weeks in the Rwenzori Mountains capturing drone photography, GPS coordinates, and ground-penetrating radar data to document glacial retreat.
Thriving Antarctic Ecosystem Revealed by a Departing Iceberg
A quick-calving iceberg gave scientists a rare glimpse into what hides beneath Antarctic ice.
Subglacial Hydrology Under the Antarctic Ice Sheet
Using simulations of subglacial hydrology, a new study shows the volume and movement of meltwater underneath the Antarctic Ice Sheet.
The Complex Evolution of Debris-Covered Glacier Surfaces
A first look at how the surfaces of debris-covered glaciers evolve over time from six years of drone surveys in the Nepal Himalaya.
Crevasses on the Greenland Ice Sheet Are Growing
High-resolution 3D maps show crevasse volume is increasing across most of the Greenland Ice Sheet as it accelerates toward the ocean, which could affect future ice loss and sea level rise.
