Climate Change 2001: The Scientific Basis

Figure 26: Simple model results: Projected global mean temperature changes when the concentration of CO₂ is stabilised following the WRE profiles (see Chapter 9 Section 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]
