Smaller rockfalls have reduced the risk of a major rock slope collapse above Blatten, but attention has shifted to the Birch Glacier, which is now moving at 10 metres per day. The Landslide Blog is written by Dave Petley, who is widely recognised as a world leader in the study and management of landslides. Over […]

Newly Discovered Algae May Speed Melting of Antarctic Ice
Purple pigmentation in a diverse array of algae absorbs heat and creates a feedback loop responsible for 2% of total daily melting.
NOAA Halts Maintenance of Key Arctic Data at National Snow and Ice Data Center
The National Snow and Ice Data Center (NSIDC) may no longer actively maintain or update some of its snow and ice data products after losing support from NOAA’s National Centers for Environmental Information, according to a 6 May announcement.
Images of the source of the 28 April 2025 landslide / GLOF at Vallunaraju in Peru
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. A few days ago I highlighted the severe landslide and GLOF that occurred on the flanks of Vallunaraju in Peru, on 28 April 2025, which caused substantial damage and at least two […]
Organic Radiocarbon Reveals its Inorganic Ancestry in Lake Geneva
Organic and inorganic radiocarbon ages resolve the origin and dynamics of carbon in the largest natural lake of Western Europe.
The 28 April 2025 Glacial Outburst Flood (GLOF) / landslide at Vallunaraju in Peru
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. On 28 April 2025, a major debris flow travelled down a channel from a major mountain, Vallunaraju, striking the communities lower down the slope. At least 100 houses were destroyed and two […]
Glaciers Offer Clues into the Path of Fossil Fuel Pollution
New research traces the origin of carbon deposited from the atmosphere onto glaciers.
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.
