Figure 26: Simple model
results: Projected global mean temperature changes when the concentration of CO2
is stabilised following the WRE profiles (see Chapter 9Section 9.3.3). For comparison, results based on the
S profiles in the SAR are also shown in green (S1000 not available). The results
are the average produced by a simple climate model tuned to seven AOGCMs. The
baseline scenario is scenario A1B, this is specified
only to 2100. After 2100, the emissions of gases other than CO2 are
assumed to remain constant at their A1B 2100 values.
The projections are labelled according to the level of CO2 stabilisation.
The broken lines after 2100 indicate increased uncertainty in the simple climate
model results beyond 2100. The black dots indicate the time of CO2
stabilisation. The stabilisation year for the WRE1000 profile is 2375. [Based
on Figure 9.16]
