23. Luke Kemp on defining, evaluating and managing catastrophic climate risk

Challenging Climate

Dr Luke Kemp is a Research Associate at the Centre for the Study of Existential Risk, University of Cambridge. He has a PhD in international relations from the ANU and previous experience as a senior economist at Vivid Economics. In this episode, Luke sheds light on a surprisingly understudied and overlooked topic – catastrophic climate risk. This episode explores catastrophic and extinction risk, why the topic is understudied, and how we can weigh out the catastrophic risks of climate change and solar geo-engineering.
