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
