Peatlands are the most efficient terrestrial ecosystems in storing carbon, which contain approximately one third of the world’s soil carbon pool and play an important role in global carbon cycling. During the last two decades, increases in dissolved organic carbon (DOC) concentrations have been observed in freshwaters across large areas of Northern Hemisphere. It is generally considered to be related to large scale DOC releasing from Northern Peatlands. Then, the authors proposed that the combining forces of temperature and hydrological processes under global change possibly are the main dominant drivers of DOC change, though multiple mechanisms for rising DOC exist.
