Climate change economics is now four decades old. Much of what it has achieved as a field of academic enquiry can be linked back to issues of integrated assessment modelling. This paper shows that the standard approach is going through a major change in scope as of the last five years. The conventional focus on determining optimal mitigation paths based on modelling the social cost of carbon is being enlarged to embrace promising new waves of research. These are: (1) the economics of insurance against catastrophic risks; (2) the economics of trade and climate; and (3) the economics of climate change adaptation. The paper helps to bridge the gap between economics and climate policy by showing that the analytical toolkit of climate change economics has shifted towards more realistic representations of climatic policy.
