Bridging the scales: The Arctic methane and permafrost challenge 

The Arctic is warming between 4-8 times faster than the global average, making permafrost soil organic carbon susceptible to degradation. The quantity and timeline of methane emissions from this carbon entering the atmosphere is uncertain. Yet, the permafrost environment is changing rapidly, permafrost thaw is leading to increasingly significant changes in landscape and biodiversity. To predict the impacts of permafrost thaw on the landscape and methane emissions, international collaboration is necessitated. To this end, ESA and NASA have established the Arctic Methane Permafrost Challenge, a transatlantic initiative bringing together circumpolar studies across scales.

The aim of this session is to further enhance the understanding of all aspects of change in the permafrost environment leading to methane emissions across all scales in the circumpolar Arctic. This symposium will invite leading figures in the field in order to understand the current state of research, and how to further understanding. The session will focus on science synergies across biodiversity and landscape studies, carbon cycling, and integrated observing technologies across international partners to build on and enhance existing Arctic science.


This session is convened by Edward Malina and Co-conveners are Kimberley Miner, Dirk Schüttemeyer, Martijn Pallandt
