Radiative forcing has a huge impact on water systems. Water vapour, being a GHG, contributes to the increase in warming. It has a positive feedback effect on the climate.
Let us see how.
Radiative forcing, thus affects earthâ€™s energy balance. This, in turn, affects the surface heat and moisture balance, thus altering the hydrological cycle.
Some forcing agents like aerosols impact precipitation by serving as nuclei for cloud formation, along with other aspects of the hydrological cycle.
