It is estimated that peatlands accumulate and hold more than one-quarter of the planet’s soil carbon, with northern peatlands accounting for upwards of 85% of this global stock. Despite their importance as a global carbon sink, the vulnerability of peatlands to climate warming is uncertain due to a lack of observational data and incomplete understanding of peat carbon dynamics. Using a process‐based biogeochemistry peatland model, researchers quantified carbon accumulation rates and carbon stocks within North America peatlands over the last 12,000 years in a first step toward more detailed modeling of peatland dynamics.
