The mathematical formulation of the damage function in En-ROADS is different from the ones used in the literature, yet the En-ROADS function can be calibrated to those as described in detail in Section 9.5 of the En-ROADS Reference Guide. This calibration, however, still leaves some gaps between the En-ROADS and the literature damage estimates, especially for the damage function of Burke et al. which has a steep increase in damage as the temperature increases from 1 to 2°C. This is because the logistic (S-shaped) damage function of En-ROADS assumes a gradual increase from today (1.1°C) onward and does not rapidly increase as the Burke et al. function does.
