Boreal-permafrost systems are still resilient against wildfires, but continuous and long-term monitoring is needed to control the impact of climate change.

Arctic Rivers Trade Inorganic Nitrogen for Organic
Climate change is shifting the makeup of a key nutrient in rivers across Russia, Alaska, and Canada, with the potential for ecosystem-wide impacts.
Cave Deposits Reveal a Permafrost-Free Arctic
Mineral cave deposits from northern Siberia show that the region was permafrost free during the late Miocene period, when Earth was warmer than today.
Water Tracks: The Veins of Thawing Landscapes
Tracing and tracking change in permafrost flowpaths could reveal the dynamics of warming poles.
Rock Glacier Velocity: Monitoring Permafrost Amid Climate Change
The movement of unique landforms called “rock glaciers” give insight into how climate change is impacting permafrost in mountainous regions.
Beyond Up and Down: How Arctic Ponds Stir Sideways
Contrary to common assumptions, Arctic ponds mix in more than one direction. A new study finds that nighttime sideways flows, not vertical mixing, renew bottom waters.
Los lagos y estanques de Alaska revelan los efectos del derretimiento del permafrost
Un nuevo conjunto de datos proporciona un método poderoso para rastrear fácilmente los cambios en el permafrost.
Alaska’s Lakes and Ponds Reveal Effects of Permafrost Thaw
A new dataset provides a powerful method for easily tracking changes in permafrost.
The timing of landslides in areas of permafrost thawing
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. There is a no scientific doubt that human activity is driving rapid warming of the terrestrial climate, and that this is amplified in high latitude and high mountain environments. An inevitable, and […]
Filling the Gaps: Context and Design of Arctic Carbon Flux Measurement Networks
Large scale observational networks are necessary for understanding the impact of a warming climate in the Arctic, but critical tools are crucial to how those networks are designed.
