“Our climate trajectory is likely going to make talik formation an important driver of permafrost degradation in the discontinuous permafrost zone and eventually, as temperatures continue to warm, in ...

Permafrost, the ground below the freezing point of water 0 º for two or more years, is an element of the cryosphere which has not been as much studied as other soils like glaciers or marine ice, ...

When I was a girl of 5, my father left me alone on the summit of a mountain in the Alps while he fetched my mother and infant brother from the trailhead below. All around me was ice, snow and sky. The ...

Landslides triggered by permafrost thaw, floodwaters gushing from melting glaciers and smokier air from bigger and more frequent wildfires are among the problems that a warming climate is expected to ...

Permafrost thaw lakes occur in high abundance across the subarctic landscape but little is known about their limnological dynamics. This study was undertaken to evaluate the hourly, seasonal, and ...

More areas of year-round unfrozen ground have begun dotting Interior and Northwest Alaska and will continue to increase in extent due to climate change, according to new research. More areas of ...
