Fig. 3: The magnitude and sign of the emergent temperature sensitivities varies between sites, short-term and long-term warming, and depth.

The figure shows the modeled depth-resolved emergent temperature sensitivity (ν) of soil organic carbon at each a Utqiaġvik, b Toolik, c Eight Mile Lake, and d Delta Junction, under short-term and the two long-term (i.e., RCP8.5-T and RCP8.5-FF) scenarios across two time periods (2045–2055 and 2090–2100). A positive ν value denotes a period where the ecosystem is acting as a sink for carbon, while a negative value indicates the ecosystem is losing carbon. Asterisk denotes periods where permafrost was simulated to occur at that depth, and therefore no change in soil organic carbon stock occurred.
