Radiative forcing / Greenhouse effect

[random39a]

How does radiative forcing relate to the greenhouse effect? Is radiative forcing part of the greenhouse effect? Or does radiative forcing cause it? I'm confused. Clear explanation needed. Thanks

The Greenhouse effect is an example of radiative forcing as a concept. RF can also refer to an actual measure of the strength of the effect.
