New research from a team at Northern Arizona University suggests that subsidence, gradually sinking terrain caused by the loss of ice and soil mass in permafrost, is causing deeper thaw than previously thought and making ...

The thawing permafrost soils in the Arctic regions might contribute to the greenhouse effect in two respects: On the one hand, rising temperatures lead to higher microbial methane production close to the surface. On the other ...
