forcing” due to the perturbation in question; and, “climate
sensitivity,” characterizing the response of the climate per
unit change in radiative forcing. Climate response is then the
product of radiative forcing and climate sensitivity. This
distinction is useful because of two approximations: radiative
forcing often can be thought of as independent of the resulting
climate response, and climate sensitivity can often be thought
of as independent of the
