Rivers and lakes at high latitudes are considered to be major sources for greenhouse gas emissions to the atmosphere, but these losses are poorly constrained. In a study published in
Nature Communications, Umeå University researchers and collaborators quantify carbon emissions from rivers and lakes across Western Siberia, finding that emission are high and exceed carbon export to the Arctic Ocean.
High latitude regions play a key role in the global carbon cycle and climate system. An important question is the degree of mobilization and atmospheric release of vast soil carbon stocks, partly stored in permafrost, with amplified warming of these regions. A fraction of this carbon is exported to inland waters and emitted to the atmosphere, yet these losses are poorly constrained and seldom accounted for in assessments of high latitude carbon balances. This is particularly relevant for Western Siberia, with its extensive peatland carbon stocks that are expecte
