Figure 9.19: (a) AOGCM stabilisation
simulations. Upper panel: 1%/yr simulations to stabilisation at and near 2xand
3xCO2. Lower panel: stabilisation experiments starting with historical greenhouse
gas forcing up to present day, then going up to 2xor 3xCO2 concentrations following
the IS92a scenario, then stabilising in the years 2050 and 2100. (b) Post-stabilisation
temperature evolution. Upper panel: Rate of change of the temperature. Lower panel:
Temperature evolution after the stabilisation of the greenhouse gas concentration.
