optimal policy balance in the context of catastrophic climate risk. The analysis uses the WITCH integrated assessment model … with a module that models the endogenous risk of experiencing an economic catastrophe if temperature increases above a … certain threshold. We find that the risk of a catastrophic outcome would encourage countries to reduce emissions even in the …

responsiveness of mitigation to changes in adaptation decreases. Compared to a world without climate catastrophes, risk reduces the … balance in the context of climate catastrophic risk. The investigation enriches an integrated assessment model introducing the … caused by GHG emissions, and ultimately abatement choices. Results indicate that the presence of catastrophic risk induces …

This study moves beyond recent catastrophe or tipping point studies with arbitrary risk … introduced here informs risk management strategies that balance uncertain future climate change impacts with the costs of …

We show that an optimal response to uncertainty substantially reduces the risk premium. …
