Scientists studying the massive August 2025 landslide and tsunami in Southeast Alaska warn that the likelihood of similar large-scale events has increased substantially across the North as glaciers retreat and permafrost degrades. The study of the Tracy Arm event revealed the rapid retreat of a supporting glacier and localized seismic signals that began days […]
Early in the morning of August 10th, 2025, a large landslide triggered a massive tsunami in the Tracy Arm Fjord in Alaska – a place frequented by tour boats and commercial cruise ships. In a new analysis, researchers show how this event unfolded and highlight both the growing hazard from similar events and the […]
Tiny particles bubbling up from the tops of melting sea ice into the Arctic sky may be a key, understudied element of cloud formation in that climate-sensitive region. Researchers from Colorado State University have published findings in Geophysical Research Letters that highlight how these airborne “ice-nucleating particles” from biological sources, such as bacteria, provide a platform […]
Weasels are small carnivores with a long body and short legs. They also have a stout skull and sharp teeth. These creatures, along with ferrets and minks, make up the Mustelinae subfamily. Until now, researchers believed that the oldest fossils from this family were from Poland and Germany, dating back to about 3.5 million […]
