AGU session: B069. Vulnerability of Permafrost Carbon to Climate Change

Christina Schädel
Dear Colleagues: Please consider submitting your AGU abstract to the following permafrost/carbon Biogeoscience session:

B069. Vulnerability of Permafrost Carbon to Climate Change
Permafrost zone soils contain 1670 Pg of carbon (C). Permafrost degradation can change ecosystem C storage by enhancing microbial activity and ecosystem respiration, but can also stimulate plant growth and increase C stored in vegetation and surface soil. This session invites papers that examine factors causing losses and gains in ecosystem C storage that relate to the question: What is the magnitude, timing and form of C release from permafrost zone ecosystems to the atmosphere in a changing climate? 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 C cycle and future climate.
