Figure 8.15: Observed (Parker/Jones)
and modelled global annual mean temperature anomalies (°C) from the 1901 to
1930 climatological average. The control and three independent simulations with
the same greenhouse gas plus aerosol forcing and slightly different initial conditions
are shown from CGCM1 (Boer et al., 2000). The greenhouse gas alone simulation
is labelled GHG. The three greenhouse gas plus aerosol simulations are labelled
GHG+Asol1, GHG+Asol2 and GHG+Asol3, respectively.
