Climate change impacts security in myriad ways and on multiple scales, from local infrastructure to international geopolitics. At the Center for Climate and Security, that has been reflected in a range of analysis covering these multiple types and levels of security risk, including a report on sea level rise and its impact on U.S. military infrastructure, and another on the connections between climate change and the Arab Spring.

Most recently, we conducted a pioneering look at the intersection of climate, security and nuclear affairs (including nuclear security and proliferation), bringing together experts from both fields to produce a roadmap for how these risks might be understood and managed together, rather than separately.
