The carbon balance of peatlands is predicted to shift from a sink to a source this century.
However, peatland ecosystems are still omitted from the main Earth system models that are
used for future climate change projections, and they are not considered in integrated
assessment models that are used in impact and mitigation studies. By using evidence
synthesized from the literature and an expert elicitation, we define and quantify the leading
drivers of change that have impacted peatland carbon stocks during the Holocene and …
