Extended Data Fig. 5: Uncertainty in estimates of HD-CO2, FD-CO2, and SC-CO2, accounting for both econometric and climate uncertainty.
From: Quantifying climate loss and damage consistent with a social cost of carbon
a,b As in Fig. 2a,b, showing total global per ton damages from 1Gt pulse of CO2 emitted in different years, beginning in 1990, cumulated using a 2% discount rate. Confidence bands account for both econometric uncertainty (regression uncertainty in estimated temperature-GDP relationship) and climate uncertainty (including uncertainty in the response of global temperature to emissions, and uncertainty in how global temperature change translates to local temperature change). c. Influence of different estimation components on uncertainty in estimates of SC-CO2, fixing other components at their median. Estimates are based on 5-lag temperature-growth relationship, assuming no growth impacts after 2100.
