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.

"PFTBA is extremely long-lived in the atmosphere and it has a very high
radiative efficiency. The result of this is a very high global warming potential.
