ABOUT

The Permafrost Carbon Network is part of the multi-million dollar Study of Environmental Arctic Change (SEARCH) project. The SEARCH project, headed by the University of Alaska Fairbanks as the lead institution and Northern Arizona University as one partner, is a system-scale, cross-disciplinary research program that seeks to connect the science of Arctic change to decision makers. The Permafrost Action Team, led by Ted Schuur will, in part, support activities developed by the Permafrost Carbon Network. The network has been successfully running since 2011 and includes more than 300 scientists from 88 research institutions located in 17 countries.

Approximately 1330-1580 Pg of soil carbon are estimated to be stored in soils and permafrost of high latitude ecosystems, which is almost twice as much carbon as is currently contained in the atmosphere. In a warmer world permafrost thawing and decomposition of previously frozen organic carbon is one of the more likely positive feedbacks from terrestrial ecosystems to the atmosphere. Although ground temperature increases in permafrost regions are well documented there is a knowledge gap in the response of permafrost carbon to climate change.

OBJECTIVES

The Permafrost Carbon Network started in 2011 and our main objectives are to synthesize existing research about permafrost carbon and climate ina format that can be assimilated by biospheric and climate models, and that will contribute to future assessments of the Intergovernmental Panel on Climate Change (IPCC).

Our activities include a series of meetings and working groups designed to synthesize ongoing permafrost carbon research which will produce new knowledge to quantify the role of permafrost carbon in driving climate change in the 21st century and beyond.
