Short summary
We apply a global Earth system model to quantify the direct impacts of anthropogenic aerosols on gross primary productivity (GPP) and isoprene emission. On the global scale, GPP and isoprene emission are not sensitive to pollution aerosols, while at the regional scale they show a robust but opposite sensitivity to pollution aerosols. We posit that anthropogenic aerosols affect land carbon fluxes (GPP and isoprene emission) via radiative and thermal mechanisms that vary across regions.
