Inhomogeneous forcing and transient climate sensitivity

Understanding how sensitive the climate is to different forcings is essential for projecting change. Analysis of results from climate model intercomparison projects shows that the climate has a greater sensitivity to aerosols and ozone compared with CO2. This result means that the low-range projections of climate response to CO2, <1.3 C, are unlikely.
