Note: Adapted from a University of Colorado Boulder news release by Yvaine Ye. More than 70 million years ago, the Arctic was a lively place for some of Earth’s ancient mammals. Today, their fossil teeth are offering clues about where they came from and how they outlived the dinosaurs. In a new study published […]
When rain falls on snow in the Arctic, ice layers can form on top of and within the snowpack. This increasingly common dynamic can influence the ability of animals, including caribou and muskoxen, to forage and move across the landscape. That, in turn, affects the people who rely on wildlife for subsistence, culture, wellbeing and income. Given the widespread impacts of rain-on-snow events, Colorado State University researchers are studying and modeling their effects in Arctic systems. The work is especially important considering the rapid rate of climate change across the region, said Stine […]
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 […]
