Permafrost thaw, and carbon released via the microbial decomposition of previously frozen soil organic matter, is considered one of the most likely positive feedbacks from terrestrial ecosystems to the atmosphere in a warmer world. The rate and form of permafrost carbon release is highly uncertain but crucial for predicting the strength and timing of this carbon cycle feedback during this century and beyond. The main objective of the Permafrost Carbon Network is to use data synthesis and modeling to link biological carbon cycle research with well-developed networks in the physical sciences focused on the thermal state of permafrost.
