An ensemble assessment to improve estimates of land-to-ocean carbon fluxes

A re-evaluation of global land-to-ocean carbon exports using a multi-model ensemble and a database of observations reveals that the export of carbon by rivers is 20% higher than that reported in the 2021 Intergovernmental Panel on Climate Change (IPCC) assessment. These findings underscore the important contribution of riverine carbon to the carbon budget.
