There is growing realization of the strong interactions between degradation of near-surface permafrost on the dynamics of ecosystems, and that these interactions together influence local and global environmental, economic, and social systems.
Degradation of near-surface permafrost (perennially frozen ground) caused by modern climate change is adversely affecting human infrastructure, altering Arctic ecosystem structure and function, changing the surface energy balance, and has the potential to dramatically impact Arctic hydrological processes and increase greenhouse gas emissions.
The Study of Environmental Change (SEARCH) (https://www.arcus.org/search-program) Permafrost Action Team is developing new knowledge about permafrost change impacts on the ecosystem services critical to local residents of the permafrost zone through research synthesis. This framework of synthesis builds on activities of the Permafrost Carbon Network (PCN) (www.permafrostcarbon.org), an international scientific effort that links biological carbon cycle research with networks in the physical sciences focused on the thermal state of permafrost.
This presentation will discuss the use of synthesis science by both the SEARCH Permafrost Action Team and Permafrost Carbon Network to identify and understand the widespread implications of changing permafrost at both regional and global scales.
