Permafrost peatlands contain globally important amounts of soil organic carbon, owing to
cold conditions which suppress anaerobic decomposition. However, climate warming and
permafrost thaw threaten the stability of this carbon store. The ultimate fate of permafrost
peatlands and their carbon stores is unclear because of complex feedbacks between peat
accumulation, hydrology and vegetation. Field monitoring campaigns only span the last few
decades and therefore provide an incomplete picture of permafrost peatland response to …
