radiative forcing

[‚rād·ē‚ād·iv ′fȯrs·iŋ]
(meteorology)
The relative effectiveness of greenhouse gases to restrict long-wave radiation from escaping back into space. For a particular greenhouse gas, radiative forcing is measured as the change in average net radiation (in watts per square meter) at the top of the troposphere, and depends on the wavelength at which the gas absorbs the radiation, the strength of absorption per molecule, and the concentration of the gas.

For their analysis, Professor Berntsen and his colleagues entered all the factors contributing to human-induced climate forcings since 1750 into their model.

The three scenarios (see figure, opposite page) were intended to bracket the range of likely future climate forcings (changes imposed on the Earth's energy balance that tend to alter global temperature either way).
In contrast, the added greenhouse gas climate forcings ranged from about +1.
He took the above sentence out of context from a paragraph in which I was being gently critical of a tendency of Intergovernmental Panel on Climate Change climate simulations to emphasize only cases with very large increases of climate forcings.
They will play crucial roles in refining our knowledge of climate forcings and Earth's response processes," he added.
These possible causes of climate change, whether natural or human-induced, are referred to as climate forcings.
