Modeling permafrost stability in peatlands with climate change and disturbance
Boreal and arctic regions are predicted to warm faster and more severely than temperate latitudes. They contain large stocks of below- ground soil carbon in peatlands and frozen soil, and the flux of the soil C to the atmosphere may be a strong feedback to climate change. Increases in air temperatur...

| Summary: | Boreal and arctic regions are predicted to warm faster and more severely than temperate latitudes. They contain large stocks of below- ground soil carbon in peatlands and frozen soil, and the flux of the soil C to the atmosphere may be a strong feedback to climate change. Increases in air temperature due to climate change will increase surface soil temperatures, soil temperatures at depth, active layer depths, and growing season length, but not degrade permafrost by 2100 at this site. Both wildfire and climate change increase active layer depths by 25 cm, but effects of wildfire diminish following vegetation recovery. |
