Short summary

While pristine, growing peatlands are often considered to be net sinks of carbon dioxide (CO2), fluxes vary considerably and these systems can be net sinks or sources of CO2. To explain part of this huge variation, here we present a phenomenon of peat moss (Sphagnum)-driven CO2 production. Due to the acid excreted by Sphagnum, bicarbonate in the surface water is transformed into CO2. Thus, while these systems have high CO2 fixation rates due to growing Sphagnum, they show a net emission of CO2.
