The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. A fascinating and important open access paper has just been published in the journal Geology (Svennevig et al. 2023) that seeks to understand the generation of tsunami waves in high latitude fjord […]

The Winds of Change: Foehn Drive Intense Melt
Atmospheric rivers on the northwestern Greenland Ice Sheet are driving dry winds across northeastern Greenland, forcing extreme short-term melt.
Another Record-Breaking Year in the Arctic Amplifies Calls for More Data
A downward spiral of the Arctic’s ecological health and climatic conditions continued in 2023, causing problems for people, plants, and animals, according to a new NOAA report.
El estallido de burbujas acelera el deshielo de los glaciares
Tener en cuenta el efecto burbuja podría mejorar las estimaciones sobre el deshielo de los glaciares submarinos y prever mejor su contracción a medida que se calientan los océanos.
Popping Bubbles Make Glaciers Melt Faster
Accounting for the newfound bubble effect could improve estimates of how sea-terminating glaciers melt underwater—and better anticipate their shrinkage as oceans warm.
Melting Glaciers as a Source of Lead in Coastal Waters
New experiments show how lead circulates through glaciers, meltwater, and sediments in polar environments.
Marine Sediments Reveal Past Climate Responses to CO2 Changes
Climate records stored in marine sediments reveal different ice sheet and ocean responses to falling atmospheric CO2 concentrations from the warm Pliocene to the ice ages of the Pleistocene.
Greenland Was Much Greener 416,000 Years Ago
A fresh analysis of a historic ice core has revealed evidence of a much smaller ice cap.
Herbivore Diversity Helps Maintain Arctic Tundra Diversity
A long-term experiment in southwestern Greenland reveals that the presence of musk oxen and caribou helps stave off declines in Arctic tundra diversity brought on by climate change.
Going with the Flow: New Tool Improves Sea Level Projections
By bringing together multiple data sources a new statistical method aims to improve the accuracy with which we might predict future ice melt in Greenland.
