View the paper “Accounting For Violent Conflict Risk In Planetary Defense Decisions”

Planetary defense is the defense of planet Earth against collisions with near-Earth objects (NEOs), which include asteroids, comets and meteoroids. A central objective of planetary defense is to reduce risks to Earth and its inhabitants. Whereas planetary defense is mainly focused on risks from NEO, this paper argues that planetary defense decisions should also account for other risks, especially risks from violent conflict. The paper is based on a talk I gave at the 2019 Planetary …

If an asteroid is found to be on collision course with Earth, it may be possible to deflect it away. One way of deflecting asteroids would be to use nuclear explosives. A nuclear deflection program may reduce the risk of an asteroid collision, but it might also inadvertently increase the risk of nuclear war or other violent conflict. This paper analyzes this potential tradeoff and evaluates its policy implications. The paper is published in …

View the paper “Uncertain Human Consequences in Asteroid Risk Analysis and the Global Catastrophe Threshold”

Asteroid collision is probably the most well-understood global catastrophic risk. This paper shows that it’s not so well understood after all, due to uncertainty in the human consequences. This finding matters both for asteroid risk and for the wider study of global catastrophic risk. If asteroid risk is not well understood, then neither are other risks such as nuclear war and pandemics.

In addition to our understanding of the risks, two other …
