Humanity faces two existential threats: nuclear annihilation and catastrophic climate change. Both have human origins, and both are linked to the use of nuclear energy. Inherent in the use of atomic fission is the risk that the technology and materials can be diverted to terrorists or hostile nations and used to make nuclear weapons. The key question is whether we can use nuclear energy to reduce the threat of climate change without increasing the risk that nuclear weapons will be used. In Double Jeopardy, Daniel Poneman argues that the world needs an "all-of-the-above" energy policy, one that advances the goal of decarbonizing the environment through all available means - including nuclear power. Poneman makes a persuasive case that we can enhance the ability of nuclear power to combat climate change even as we reduce the risks of nuclear terror.
