Temperature

The temperature model computes the evolution of atmospheric and ocean temperature following change in CO2 concentration. It contains three equations, one for the radiative forcing and two equations for the climate system, all extracted from DICE model with no modification. It is completed by an Etminan model for CH4 and NO2 emissions impact (improved version of the Myhre model especially for methane impact). A transfer coefficient is then applied to estimate ocean temperature change and deep ocean temperature change.

Damages

The Damage model estimate damage on economy, feeds macro-economy model for damage to productivity, and feeds population model for damage to population (heat, increased pandemic diseases...). It combines classical DICE damages, with a Weitzman tipping point model (some discussion on tipping point controversy and value tuning is included in damage model documentation)
