Abstract
We analyze Nordhaus’ DICE model and show that the temperature and CO2 equations are needlessly complicated and can be simplified without loss of essence. In addition, we argue that the damage function can be altered in such a way that it lends itself to experiments involving extreme risk. We conclude that, within the philosophy of the DICE model, significant simplifications can be made which make the model more transparent, more robust, and easier to apply.

In this Appendix, we present two tables which together contain all variable and parameter definitions required to compute the optimum in DICE (the Nordhaus model) and S-DICE (our simplified version of DICE): the variables employed in S-DICE and DICE and their relationship, and the initial values of the six state variables of DICE (Table 4); and the parameters employed in S-DICE and DICE and their relationship (Table 5).
