Modeling Pan‐Arctic Peatland Carbon Dynamics Under Alternative Warming Scenarios

Peatlands store large amounts of carbon in terrestrial ecosystems and they are vulnerable to recent warming. The ongoing warming may change their sink capacity could reduce potential sequester carbon. In this study, we simulated peatland dynamics distinct future climate conditions using the peatland-vegetation model (LPJ-GUESS). study examined whether less pronounced further enhance buffer effects change. It also determined which trajectory balance would follow, what main drivers were, one dominate future. We found that peatlands will largely retain under scenario RCP2.6 RCP6.0. They projected shift from a carbon-neutral (5–10 gC m−2 yr−1) RCP8.5. Higher respiration rates net productivity warmer world leading reduction capacity.
