Radiative Forcing Functions
A number of different inputs can give rise to radiative forcing. In addition to the downwelling radiation due to the greenhouse effect, the IPCC First Scientific Assessment Report listed solar radiation variability due to orbital changes, variability due to changes in solar irradiance, direct aerosol effects (e.g., changes in albedo due to cloud cover), indirect aerosol effects, and surface characteristics.

Famous quotes containing the words forcing and/or functions:
“Already determined dawn began to lay
In place across a cloud the slender ray
For prying beneath and forcing the lids of sight,
And loosing the pent-up music of overnight.”
—Robert Frost (1874–1963)
“Those things which now most engage the attention of men, as politics and the daily routine, are, it is true, vital functions of human society, but should be unconsciously performed, like the corresponding functions of the physical body.”
—Henry David Thoreau (1817–1862)
