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.
A new resource makes it easier for researchers to explore predictions of how melting permafrost might affect carbon release, wetlands, and river deltas as they evolve and other interacting effects.
Physical parameters may help scientists extrapolate Arctic carbon soil losses from the local to the regional scale, according to the results of a yearlong incubation experiment.
New findings highlight the need to account for large amounts of ground ice contained in frozen soil when assessing Arctic carbon cycling.
Climate change could spur greenhouse gas release from the Arctic. A new project will synthesize existing data to improve uncertain predictions.
Do water levels in high-latitude Canadian lakes fluctuate as one body or as separate entities? The answer could reveal clues to how melting permafrost influences the environment.
