The Imminent Calving Retreat of Taku Glacier
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.
Arctic Report Card Founder Discusses the Fate of the Pole
Researcher Jackie Richter-Menge has reported on the status of the melting Arctic for the past 15 years. Her observations tell a story of “mind-blowing change.”
Experimentos Revelan Cómo el Carbono del Permafrost se Convierte en Dióxido de Carbono
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.
Building an Early-Career Researcher Community from the Ground Up
An international group of early-career scientists has developed its own network to virtually moor connections within the peatlands community.
Lake Ice—and Ecosystems—in a Warming World
Extending ice records and standardizing sampling protocols are among recommendations to help researchers better predict how changing ice cover will affect aquatic ecosystems.
Glacial Contributions to 21st Century Sea Level Rise
Researchers identify the main sources of uncertainty in projections of global glacier mass change, which is expected to add about 8–16 centimeters to sea level, through this century.
Big Questions, Few Answers About What Happens Under Lake Ice
Scientists long eschewed studying lakes in winter, expecting that cold temperatures and ice cover limited activity below the surface. Recent findings to the contrary are changing limnologists’ views.
How Will Climate Change Affect Arctic Stream Slime?
Rising temperatures and thawing permafrost will change nutrient concentrations in Arctic waterways, which will influence the growth of biogeochemically important biofilms.
Organic Matter in Arctic River Shows Permafrost Thaw
Samples from two waterways in northern Siberia—the main stem of the Kolyma River and a headwater stream in the river’s watershed—indicate the differing sources and ages of carbon they contain.
