WebRadiative Forcing. Radiative forcing is the change in the net, downward minus upward, radiative flux (expressed in Watts per square metre; W m-2) at the tropopause or top of atmosphere due to a change in an external driver of climate change, such as, for example, a change in the concentration of carbon dioxide (CO 2) or the output of the Sun.

Further, if the climate system is naturally sensitive to a range of different influences, how does that make artificially doubling a (naturally occurring) atmospheric constituent a consequence free action?

We examine the climate response to solar irradiance changes between the late 17th-century Maunder Minimum and the late 18th century. Global average temperature changes are small (about 0.3° to 0.4°C) in both a climate model and empirical reconstructions. However, regional temperature changes are quite large.
