Alaska’s Lakes and Ponds Reveal Effects of Permafrost Thaw
A new dataset provides a powerful method for easily tracking changes in permafrost.
Checking in on three earlier fatal landslides
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. My regular scans of reports of landslides around the world has highlighted interesting updates on three events of the last year or so. The 14 December 2024 Lions Bay Landslide The Vancouver […]
Wave-Modulated Electron Loss Affects GPS Location Determination
Earth’s magnetosphere controls ionospheric total electron content modulation via plasma wave-induced electron loss impacting GPS spatial location determination.
Alaska’s Mount Veniaminof Volcano Is Stealthy—Here’s Why
New research explains why Mount Veniaminof erupts without the usual warming signs.
Arctic Beavers Advance North and Accelerate Permafrost Thaw
As beavers build dams in new areas, they impound water, warming permafrost adjacent to their ponds.
The Delicate Balance of Permafrost in Arctic River Floodplains
To evaluate the vulnerability of permafrost in Arctic floodplain landscapes to warming, scientists explore dynamics of its loss and reformation.
Simulating Arctic Carbon Emissions in a Warming World
Not all climate models include carbon from thawing permafrost, and those that do often disagree. Scientists are working to better inform models and assess how these crucial materials are simulated.
The 7 August 2024 Pedersen Lagoon landslide and tsunami
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. At about 5 am local time on 7 August 2024, a large landslide occurred on the rock slopes above Pedersen Lagoon in Alaska, triggering a local tsunami. Whilst this major event is […]
Cloud Brightening Could Have Unintended Effects in a Warming World
New research shows that though marine cloud brightening holds potential to temporarily reduce heat stress regionally, the technique has unpredictable and far-reaching outcomes.
