Researchers used satellite data to trace ground subsidence in a permafrost-rich region in eastern Siberia following a wildfire.
In comparing soils from two tundra wetland landscape positions, landscape position is found to matter, and toeslopes are associated with higher greenhouse gas production.
Field samples from Alaska show how sunlight and iron convert permafrost carbon to carbon dioxide. Climate models ignore this process.
Arctic infrastructure is under threat from thawing permafrost.
New research examines how shifts in aboveground ecology influence belowground hydrology in the Arctic.
Thick, fluffy snow traps summer’s heat in the top layers of Arctic permafrost even as winter chills the air above. Grazing animals stomp that snow flat.
Arctic coastlines have not been considered carefully in carbon cycles for long, but new research suggests that eroding permafrost may emit more greenhouse gases than previously thought.
As climate warms, Arctic rivers carry higher flows and flood earlier in the spring, causing underlying permafrost to thaw rapidly.
Geophysicists have discovered a way to monitor permafrost thaw by measuring seismic waves so gentle they don’t shake a thing.
Nitrogen released into the soil from thawing permafrost in the Arctic could accelerate soil carbon decomposition and alter carbon dynamics, with global implications.
