Global Warming Could Rob Liquors of Their Flavor
A new study examines the impact of glacial extinction on biodiversity in alpine regions.
Development and Climate Change Contribute to a Himalayan Tragedy
Infrastructure projects like roads and dams destabilize slopes and compound the effects of glacial floods and avalanches, scientists say.
The Imminent Calving Retreat of Taku Glacier
Long an anomaly among glaciers, advancing while most others shrank, Taku Glacier is starting to succumb to climate change, offering an unprecedented look at the onset of tidewater glacier retreat.
Overturning in the Pacific May Have Enabled a “Standstill” in Beringia
During the last glacial period, a vanished ocean current may have made the land bridge between Asia and the Americas into a place where humans could wait out the ice.
Cape Cod: Shipwrecks, Dune Shacks, and Shifting Sands
Living in Geologic Time: How long will the cape keep its fist raised against the waves?
Dust from Receding Glaciers May Have Major Atmospheric Impacts
New research is helping scientists understand how Arctic dust created by receding glaciers affects local air quality and global climate.
Tracing the Moisture That Nourishes the World’s Highest Glacier
Using data from weather stations on and around Mount Everest, scientists find that the Khumbu Glacier receives most of its moisture from the Bay of Bengal.
An Ice Probe on Earth Could Help Us Find Life in Space
An instrument called WATSON can help find biosignatures on icy ocean worlds.
Gravity Data Reveal Unexpected Antarctic Ice Variations
A new analysis of long-term satellite records shows the East Antarctic Ice Sheet is unexpectedly dependent on fluctuations in weather. This study may improve models of how much sea levels will rise.
