"Fast and slow climate system responses to solar geoengineering"

Factors that affect the radiative forcing of climate rapidly alter the atmosphere before substantial change in ocean temperatures occur (fast climate response). Later, the climate system responds to changes in ocean temperature (slow climate response). Numerical simulations indicate that the fast climate response can differ markedly across radiative forcing agents but their slow responses are similar. Solar geoengineering largely 'works' because solar geoengineering is good at offsetting the slow climate response to greenhouse gas forcing. In contrast, most of the mismatches between solar geoengineering and greenhouse-gas induced warming is due to the differing characteristics of the fast response to different radiative forcing agents.
