Table 2 shows summary results for equilibrium climate responses to external
forcing produced by changing CO 2 -concentrations or aerosol emissions. Rows 1-3
concern the effect of aerosol changes from pre-industrial times; rows 4-5 the
effect of increasing CO 2 by 63%, rows 6 and 7 the effect of CO 2 -doubling, and
row 8 the effect of a combined 63% increase in CO 2 and an aersol change from PI
to PD. In Fig. 1 more details are shown for the results in rows 5 and 8.
Fig. 1. Equilibrium climate response to two sets of external forcing shown for zonal average
daily precipitation, mm d − 1 (a); Cloud liquid water mass mixing ratio, ppm (b, c); SO 4 mass
mixing ratio, ppb (d, e). Continuous curve in (a) and plots to the left (b, d) show effects of a 63%
CO 2 increase with present-day aerosol emissions (PD); Dashed curve in (a) and plots to the right
(c, e) show effects of a combined 63% CO 2 increase and aerosol emissions change from PI to PD
