Lessons from the Cambridge Conference on Catastrophic Risk 2026

This post reflects on the 2026 Cambridge Conference on Catastrophic Risk, examining governance challenges across nuclear war, AI and the information ecosystem, pandemics, and climate change. It argues that the field is increasingly shifting its attention from human extinction toward potentially severe global catastrophes and that prevention alone is insufficient, particularly given persistent failures to address well-recognised risks. Drawing on conference discussions, the author highlights weakening nuclear governance, degradation of the information environment, climate tipping points, institutional shortcomings, and inadequate preparedness, while identifying important gaps around food, energy, material constraints, and accountability for catastrophic-risk governance. The post calls for anticipatory governance that combines prevention with resilience, acts at scales where cooperation is feasible, changes what systems reward, establishes clear national accountability for catastrophic-risk governance, and organises around interconnected systems such as food, energy, materials, and information as well as hazards.
