We use perturbation methods to derive a rule for the optimal risk-adjusted social cost of carbon (SCC) that … different aversions to risk and intertemporal fluctuations, convex damages, uncertainties in economic growth, atmospheric carbon …-run climate feedbacks. Our non-certainty-equivalent rule for the SCC incorporates precaution, risk insurance, and climate …
