Planning for Catastrophic Climate Risk
Catastrophic climate scenarios are dangerously understudied. There are no standard, accessible ways to assess global catastrophic risk in general. We know the least about the scenarios that matter most. This project will remedy the problem by developing robust, transparent, low-cost, and easily updated tools to assess catastrophic risk and the frameworks to make emergency decisions, even under deep uncertainty. The project will create “integrated catastrophe assessments,” which explore how catastrophic scenarios could unfold, and provide frameworks to identify mitigation options and make emergency decisions. The current potential tools include an updatable database on extreme risks, an AI assistant trained on the extreme risk database, a set of expert maps, and a framework for decision-making based on comparing the worst-case risks of different policy options.

Luke researches the history and future of extreme global risk. He is a Research Affiliate at the Centre for the Study of Existential Risk (CSER) at the University of Cambridge, and a Visiting Fellow with the Cascade Institute. He has advised and led foresight studies for multiple international institutions, including the WHO and Convention on Biological Diversity. His work has been covered by media outlets such as the BBC, the New York Times, and the New Yorker. He holds both a Doctorate in International Relations and a Bachelor of Interdisciplinary Studies with first class honours from the Australian National University (ANU). His first book, Goliath’s Curse: The History and Future of Societal Collapse, will be published with Penguin in July 2025.
