CSER (The Centre for the Study of Existential Risk) is an interdisciplinary research centre within the University of Cambridge who study existential risks, develop collaborative strategies to reduce them, and foster a global community of academics, technologists and policy-makers working to safeguard humanity. Our research focuses on biological risks, environmental risks, risks from artificial intelligence, and how to manage extreme technological risk in general.

CSER’s work on nuclear weapons includes the global consequences of nuclear weapon use (such as climate impacts on human societies, cascade and social effects, etc). Drawing on the latest scientific modelling showing our best estimates of the climate consequences, we look at public awareness and the impact of this work on defence policies and on government resilience programmes. We also look at the management of uncertainty with regards to nuclear weapons, doubts around the stability of nuclear deterrence, and the impacts of emerging disruptive technologies.
