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.  Links: Luke Kemp’s profile Check out Luke’s paper, Climate Endgame: Exploring catastrophic climate change scenariosLuke's paper on the risky perspective shift in temperature rises: Focus of the IPCC Assessment Reports has shifted to lower temperatures  Cambridge release, Climate change: potential to end humanity is “dangerously underexplored”  Additional reading: Catastrophic climate risks should be neither understated nor overstated (Burgess et al., 2022)Support the show
