Old carbon routed from land to the atmosphere by global river systems
Nature, Published online: 04 June 2025; doi:10.1038/s41586-025-09023-wUsing a global database of the radiocarbon content of rivers combining new and published measurements, isotopic mass balance suggests that about 60% of river CO2 emissions are derived from millennial or older carbon sources.
