Amplification of the direct solar forcing is conceivable, e.g., through effects on ozone or atmospheric condensation nuclei, but empirical data place a factor of two upper limit on the amplification, with the most likely forcing in the range 100 — 120 % of the directly measured solar irradiance change [64].

This increases the sensitivity to solar irradiance changes just as it increases the sensitivity to longwave (i.e., greenhouse) radiative forcing. (realclimate.org)
