Response of the climate system to anthropogenic aerosols

In general, aerosols influence the climate directly by scattering and absorbing the solar radiation and indirectly by acting as cloud condensation nuclei and ice nuclei, which modify the radiative properties of clouds. To estimate the effects of anthropogenic aerosols on the climate in future, we used earth system model simulations. The emission of anthropogenic aerosols can be decreased by controlling air pollution. If the emission of anthropogenic aerosol drops to zero abruptly, the surface temperature will rise in a short span of time. However, the surface temperature will decrease if the emission of anthropogenic aerosols is doubled suddenly. These results indicate that aerosols have immediate effects on climate change.
