Influence of anthropogenic aerosol deposition on the relationship between oceanic productivity and warming
Satellite data and models suggest oceanic productivity is reduced in response to less nutrient supply under warming. In contrast, anthropogenic aerosols provide nutrients and exert a fertilizing effect, but its contribution to evolution of oceanic productivity is unknown. We simulate the response of...
