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.
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.”
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.
An international group of early-career scientists has developed its own network to virtually moor connections within the peatlands community.
Extending ice records and standardizing sampling protocols are among recommendations to help researchers better predict how changing ice cover will affect aquatic ecosystems.
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.
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.
Rising temperatures and thawing permafrost will change nutrient concentrations in Arctic waterways, which will influence the growth of biogeochemically important biofilms.
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.
A new study compares the accuracy of three observation-based methods of calculating snow water equivalent, a key component in water management.
