  • Peatlands represent a vast store of global carbon. Observations of rapidly rising dissolved organic carbon concentrations in rivers draining peatlands have created concerns that those stores are beginning to destabilize. Three main factors have been put forward as potential causal mechanisms, but it appears that two alternatives—warming and increased river discharge—cannot offer satisfactory explanations. Here we show that the third proposed mechanism, namely shifting trends in the proportion… CONTINUE READING
