«Since the ocean component of the climate system has by far the biggest heat capacity», I've been wondering if the cool waters of the deep ocean could be used to mitigate the effects of global warming for a few centuries until we have really depleated our carbon reserves and the system can begin to recover on its own.
While the definition of a forcing may appear a little arbitrary, the reason why radiative forcing is used is because it (conveniently) gives quite good predictions of what happens in models to the global mean temperature once the climate system has fully responded to the change.
In the same way, a «greenhouse gas only» scenario can not be verified by observed data, because the real climate system has evolved under both greenhouse gas and aerosol forcing.
