Enhanced vegetation productivity driven primarily by rate not duration of carbon uptake

Nature Climate Change, Published online: 10 April 2025; doi:10.1038/s41558-025-02311-3

Using satellite and carbon-flux data, the authors show that enhanced gross primary productivity in recent decades is driven primarily by increases in the rate, rather than the duration, of carbon uptake. They highlight asymmetric changes in productivity across seasons, which may worsen under climate change.
