Definition:
A change imposed upon the climate system which modifies the radiative
balance of that system. The causes of such a change may include changes in
the sun, clouds, ice, greenhouse gases, volcanic activity, and other
agents. Radiative forcing is often specified as the net change in energy
flux at the troposphere (watts per square meter). Radiative forcing may
sometimes be referred to as external forcing or perturbations of the
climate.
