Short summary
Tropical peatlands store ancient carbon and have been identified as both being vulnerable to future climate change and taking a long time to recover after a disturbance. It is unknown if these gases are produced from decomposition of 1000-year-old peat. Radiocarbon dating shows emitted gases are young, indicating that surface carbon (rather than old peat) drives emissions. Preserving these ecosystems can trap old carbon, mitigating climate change.
