Thawing permafrost causing the 'browning' of northern lakes

The organic carbon found in permafrost is being released as the ice melts after ages of confinement in the soil, and making its way into Arctic and subarctic lakes and ponds, modifying their composition. These are the findings ...

Why thawing permafrost matters

In Bethel, Alaska, walls are splitting, houses are collapsing, and the main road looks like a kiddy rollercoaster. In the coastal town of Kongiganak, sinking cemeteries prevent Alaskans from burying their dead in the ground. ...

Tundra loses carbon with rapid permafrost thaw

Frozen in permafrost soil, northern latitudes store almost twice as much carbon as is currently in the atmosphere. Rapid Arctic warming is expected to expose previously frozen soil carbon to microbial decomposition and increase ...

Study measures methane release from Arctic permafrost

A University of Alaska Fairbanks-led research project has provided the first modern evidence of a landscape-level permafrost carbon feedback, in which thawing permafrost releases ancient carbon as climate-warming greenhouse ...
