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).
