As climate warms, Arctic rivers carry higher flows and flood earlier in the spring, causing underlying permafrost to thaw rapidly.

Small Seismic Signals Tell a Story of Iceberg Calving
Seismic signals detected hundreds of kilometers away from Greenland glaciers reveal the calving style and iceberg size.
The Permafrost Listeners
Geophysicists have discovered a way to monitor permafrost thaw by measuring seismic waves so gentle they don’t shake a thing.
Landslide Activity Ramps Up With Extreme Rainfall
An increase in activity of hundreds of slow-moving landslides during extreme wet conditions in California provides insights into the landscape response to ongoing climate change.
Arctic Glacial Retreat Alters Downstream Fjord Currents
High-resolution mapping efforts could improve predictions of coastal changes as glaciers shrink around the world.
Missing Lakes Under Antarctic Ice Sheets
New radio sounding study finds little evidence of lakes under Antarctica’s Recovery Glacier.
Enabling Dynamic, Regional-Scale Modelling of Outburst Floods
The GeoClaw model is used to simulate a landslide-dam outburst flood through rugged Himalayan topography.
Study of Alaskan Landslide Could Improve Tsunami Modeling
A rare submarine landslide provides researchers with a reference point for modeling the biggest tsunamis.
Subglacial Water Can Accelerate East Antarctic Glacier Flow
Airborne radar from the Recovery Glacier system demonstrates the importance of characterizing the underlying causes of ice flow speedup to understand how glacial discharge could change in the future.
