The US Government (USG) is hard at work identifying the range of climate security risks and opportunities so that US policymakers can best take action to protect our national security in a changing world. Congressionally mandated activities, such as the Climate Security Advisory Council—which brings together the US Intelligence Community and US Federal Science Agencies—and the National Academies Climate Security Roundtable—which leverages non-government experts—continue to explore both the physical and transition security risks of climate change. To help advance the work of policymakers and position the US at the forefront of knowledge, foundational research at the intersection of climate science and security analysis is needed, e.g., how climate risks influence environmental, infrastructure, and human impacts around the world. The complex and multi-dimensional nature of this challenge requires greater cross-disciplinary work that leverages the unique expertise from different research fields and embraces the systems-level approach required to respond to climate security risks. This agency update will provide an overview of observational, modeling, and analytic capabilities that are needed by the USG to support climate security analyses, how to combine output from these models with use cases and historical data and experience.
