Climate risk should be priced. The pricing of non-diversifiable risks implies that the price is a function of expected damages plus a risk premium. When we fail to include climate as a risk, we ignore the potential effects of "tail events" that could be catastrophic. The appropriate government policy today is to price climate related emissions to change human behavior in a short period of time.
