It has interfered with the hydrological cycle by reducing evaporation and may have reduced rainfall in some areas. Global dimming also creates a cooling effect that may have partially counteracted the effect of greenhouse gases on global warming. In basic terms, less sunlight is reaching the Earth because of visible air pollution, which is reflecting the light back into space.
