Predicting the Next Big Frost Quake
Frost quakes occur in boreal regions when rapidly expanding ice underground causes frozen soils to fracture. A recent frost quake in Finland has given scientists a rare look into how they form.

Where Does the Carbon Go When Permafrost Coasts Erode?
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.

Permafrost Thaws Rapidly as Arctic River Flooding Increases
As climate warms, Arctic rivers carry higher flows and flood earlier in the spring, causing underlying permafrost to thaw rapidly.
