Shrinking snowpack, thawing permafrost, and shifting precipitation patterns have widespread consequences. Can new technologies—and public policies—help communities adapt?
With infrastructure, experience, and a slice of the world’s largest snow biomes, Alaska is an essential research destination for NASA’s multiyear SnowEx campaign.
An ongoing project in northern Alaska is using pulses of laser light to monitor anthropogenic activity, ice quakes, and marine wildlife.
Long an anomaly among glaciers, advancing while most others shrank, Taku Glacier is starting to succumb to climate change, offering an unprecedented look at the onset of tidewater glacier retreat.
Muestras de campo provenientes de Alaska muestran cómo la luz solar y el hierro convierten el carbono del permafrost en dióxido de carbono. Los modelos climáticos ignoran este proceso.
Fieldwork is revealing a history of landscape evolution over the past 5 million years that links climate change and river capture to critical mineral resources across the Alaska-Yukon border.
Field samples from Alaska show how sunlight and iron convert permafrost carbon to carbon dioxide. Climate models ignore this process.
Using autonomous kayaks, researchers carried out measurements of water properties near the terminus of LeConte Glacier and showed that ice/ocean interactions are more complex than thought.
Scientists examine how best to use science to help communities respond to rapid climate change in the Arctic.
Scientists find links between delayed freezing of Alaskan soils and higher atmospheric methane concentrations during the cold season.
