Figure 12: Annual mean surface temperature response of the BMRC (Bureau of Meteorology Research Center, Australia) GCM to a 1%/yr increase in CO2 averaged around the time of doubled CO2. The values are the increased CO2 run minus a control run. The BMRC GCM does not employ "flux corrections" to insure a stable climate in the control runs of the model (Houghton et al. 1996).
