Expect to be surprised
Expect Relative to 1861-1899to be surprised

…it is prudent for security analysts to expect climate surprises in the coming decade, including

  • Single events that were once considered rare

  • Simultaneous or sequential conjunctions of events that stress response capacity

  • Shocks to globally integrated systems (e.g., food supply, strategic commodities, public health)

  • Impacts occurring far from triggering events

    The surprises are most likely to result from the interaction of climate events and social circumstances

    Troublesome interactions can be expected to become progressively more serious and more frequent over time, probably at an accelerating rate

Three areas of focus
Three areas of focus of security concern

  • Social and political stresses outside the USA

  • Events that exceed the capacity of affected countries or populations to cope and respond (i.e. disruptive events)

  • Risks that call for action in the coming decade

Some basic conclusions
Some of security concern basic conclusions

  • The overall risk of disruption is determined by the interplay of

    • event severity,

    • exposure of people or valued things, and

    • vulnerability of those people or things, including susceptibility to harm and the effectiveness of coping, response, and recovery

  • Exposure and vulnerability may pertain to the direct effects of a climate event or to effects mediated by globalized systems that support the well-being of the society

Need for stress testing
Need for of security concern stress testing

  • The intelligence community should establish a system of periodic “stress testing” for countries, regions, and critical global systems regarding their ability to manage potentially disruptive climate events of concern

  • Stress tests would focus on potentially disruptive conjunctions of climate events and socioeconomic and political conditions

Recommendations for monitoring
Recommendations for monitoring of security concern

Develop a systematic and enduring whole-of-government strategy for monitoring threats connected to climate change in order to inform choices about reducing vulnerability

  • Build the scientific basis for indicators of climate event risks, exposures, vulnerabilities, and factors linking these to societal and security outcomes

  • Develop and periodically update priorities for high-resolution monitoring

  • Integrate quantitative indicators with traditional analytical methods
