Radiative forcing meaning A change in average net radiation at the top of the troposphere (known as the tropopause) because of a change in either incoming solar or exiting infrared radiation. A positive radiative forcing tends on average to warm the earth’s surface; a negative radiative forcing on average tends to cool the earth’s surface. Greenhouse gases, when emitted into the atmosphere, trap infrared energy radiated from the earth’s surface and therefore tend to produce positive radiative forcing. Also see Greenhouse gases.
Radiative Forcing meaning in Science terminology / glossary / dictionary is: A measure of the influence of a particular factor (e.g. greenhouse gas (GHG), aerosol, or land use change) on the net change in the Earths energy balance.
