Nuclear Escalation

The most probable pathway to the end of the modern world is a nuclear conflict triggered by geopolitical escalation or miscalculation. Unlike climate change, which unfolds over decades, or emerging technologies whose risks remain harder to quantify, nuclear weapons present an immediate, proven capacity to collapse civilization.

Global tensions among nuclear-armed states remain high, arms-control frameworks have weakened, and new technologies such as cyber operations, missile defenses, and AI-assisted command systems increase the risk of accidental or rapid escalation. Even a limited nuclear exchange could ignite firestorms, inject soot into the atmosphere, disrupt global agriculture, and cause mass famine. A full-scale war could effectively end industrial civilization.
