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.
How Do You Make Earth into an Icehouse?
A new model accurately reconstructs Earth’s past icehouses and indicates there’s no one driver behind them.
Tiny Icequakes Ripple Through Greenland’s Largest Ice Stream
Seismologists made an accidental discovery on the Northeast Greenland Ice Stream, changing the way glaciologists understand how ice moves.
The Pulsed Pace of Glacial Erosion
New data from Lago Argentino, Patagonia reveal that glacial erosion occurs in discrete pulses, which challenges previous ideas that erosion rates have increased over time due to climate change.
Ice boost! Why Rock Avalanches Containing Ice Travel So Far
Researchers identify a new mechanism that allows avalanches containing a mixture of rock and ice to travel very long distances.
