You can of course add radiative forcing "linearly". (What other kind of addition is there?)
An important question is whether climate response to the sum of radiative forcings is the same as the sum of the climate responses to individual radiative forcings. The answer to this question depends on the size of the perturbation and your tolerance for approximation. Recall the maxim: "*To first order, everything is linear !!"* ( More strictly speaking, "*To first order, differentiable functions are linear.*" ) On Wed, Dec 31, 2008 at 11:13 AM, Stuart Strand <[email protected]>wrote: > > Is radiative forcing additive linearly? > > = Stuart = > > Stuart E.
