The impact of permafrost thawing on the carbon dynamics of tundra
International audience There is debate on the potential release of the tundra's immense carbon stocks into the atmosphere in response to global warming. We present here results obtained with a model of CO 2 exchanges, coupled to a model of the soil thermal and hydrological regime in the tundra....

International audience There is debate on the potential release of the tundra's immense carbon stocks into the atmosphere in response to global warming. We present here results obtained with a model of CO 2 exchanges, coupled to a model of the soil thermal and hydrological regime in the tundra. We show that, because of the partial thawing of permafrost and subsequent increase in nutrient availability, the ecosystem's response to warming may be a long-lasting increase in C accumulation, following a temporary increase in CO 2 emissions.
