This loop is called permafrost–carbon feedback, and as this effect is strengthening itself, it is [...] ked a large amount of carbon. To assess the concern of a permafrost carbon feedback and to develop a better understanding of future permafrost-carbon dynamics, the PETA-CARB project aims at quantifying

deep permafrost soil carbon pools to rapid thaw and resulting impacts. The three research topics were: (1) Systematic measurement of rapid permafrost thaw, (2) Characterization of deep permafrost SOC stocks [...] PETA-CARB wordle (Graphic: Alfred Wegener Institut) What is Permafrost? Carbon in Permafrost Arctic landscapes, especially those underlain by permafrost, are threatened by climate warming and may degrade in [...] Wegener Institut) Arctic permafrost deposits are estimated to freeze-lock as much carbon in the atmosphere, allowing a potentially significant climate warming feedback loop when permafrost thaws and carbon is
