Most lakes are net sources of CO2; conventionally the CO2 in lake waters is attributed to in-lake oxidation of terrestrially-produced dissolved organic carbon. Now research indicates that CO2 in lakes may be delivered directly via inflowing streams. These findings suggest that future CO2 emissions from lakes will be strongly related to productivity in the lake catchment.
