How do we plan for disasters that have never occurred before? One million species are at risk of extinction in the near future from environmental changes. The frequency of historic tropical storms is increasing. The rapidly melting permafrost in the Arctic is placing unprecedented pressures on northern infrastructure. Given the overwhelming and unpredictable nature of new disaster risks, it is not clear what the appropriate responses should be. Our book, Disaster Security: Using Military and Intelligence Planning for Energy and Environmental Risks, addresses how to assess unique environmental hazards and disaster risks, based on tools used by the U.S. intelligence and military communities. The book draws on lessons learned from developing, applying, and translating scenarios and simulations (or wargames) to plan for future environmental security risks.
