Fig. 3 Results from a coupled climate-economy model that was originally developed by economists at Yale University. The upper figure (a) shows, year by year, the reduction in CO2 emissions that the model prescribes for optimum economic benefit. The lower figure (b) gives the resulting atmospheric concentrations of CO2. Results are shown for two different time preference discount rates: 3%/yr in black, and 0 in blue. As in Figure 2, dashed and solid lines distinguish the carbon cycle model that was employed: results from the more rudimentary model in dashed lines, and from a more advanced model as solid lines.
