Climate Change 2007: The Physical Basis

Figure 2.20: Global mean radiative forcings from the agents and mechanisms grouped by agent type. Anthropogenic radiative forcings and the natural direct solar radiative forcing are shown. Columns indicate other characteristics of the radiative forcing; efficacies are not used to modify the radiative forcings shown. Time scales represent the length of time that a given radiative forcing term would persist in the atmosphere after the associated emissions and changes ceased. No CO2 time scale is given, as its removal from the atmosphere involves a range of processes that can span long time scales, and thus cannot be expressed accurately with a narrow range of lifetime values.
