Radiative Forcing

In climate science, radiative forcing is generally defined as the change in net irradiance between different layers of the atmosphere. Typically, radiative forcing is quantified at the tropopause in units of watts per square meter. A positive forcing (more incoming energy) tends to warm the system, while a negative forcing (more outgoing energy) tends to cool it. Sources of radiative forcing include changes in insolation (incident solar radiation) and in concentrations of radiatively active gases and aerosols.

Famous quotes containing the word forcing:

    no arranged terror: no forcing of image, plan,
    or thought:
    no propaganda, no humbling of reality to precept:
    terror pervades but is not arranged, all possibilities
    of escape open: no route shut,
