Increase in global warming potential of atmospheric black carbon since 1750

Nature Geoscience, Published online: 08 September 2026; doi:10.1038/s41561-026-02085-z

The soot fraction of global black carbon emissions increased from 16% in 1750 to 35% in 2019, mainly driven by fossil fuel consumption, suggesting a higher warming potential per unit mass, according to an analysis of atmospheric measurements.
