B41J:
Vulnerability of Permafrost Carbon to Climate Change II


Session ID#: 8594

Session Description:
Permafrost zone soils contain between 1330-1580 Pg of carbon. Permafrost degradation can change ecosystem carbon storage by enhancing microbial activity and ecosystem respiration, but can also stimulate plant growth and increase carbon stored in vegetation and surface soil. While increased permafrost carbon emissions in a warming climate are more likely to be gradual and sustained we need a better understanding of the magnitude and timing of greenhouse gas emissions from these remote regions to fully estimate the potential feedback from permafrost carbon to climate change.

This session invites papers that examine factors causing losses and gains in ecosystem carbon storage relating to the magnitude, timing and form of carbon release from permafrost. Papers may address any aspect of this topic from microbial communities to the global scale, using a range of measurements or modeling to detect and forecast permafrost thaw and the influence on the carbon cycle and future climate.
