In 2020, the U.S. Congress created an interagency Climate Security Advisory Council (CSAC) to deepen collaboration and bridge organizational boundaries between federal agencies on climate security issues. The CSAC is chaired by the Office of the Director of National Intelligence (ODNI) and convenes senior officials from intelligence agencies and federal science agencies to better understand and anticipate the ways climate change affects U.S. national security interests.
The following year, in 2021, Congress directed ODNI and the National Academies of Sciences, Engineering, and Medicine to work together to establish a Climate Security Roundtable (CSRT or Roundtable) as a platform for federal officials to engage a much larger community of climate experts outside of government (see Box A-1). The Roundtable convenes volunteer members drawn from academia, the private sector, and civil society to support the U.S. Intelligence Community in leveraging expertise and capabilities outside of the federal government and to better inform national security assessments. The Roundtable also includes the CSAC officials as members ex officio. At the direction of Congress, the National Academies hosts quarterly Roundtable meetings and organizes at least two workshops each year focusing on priority topics identified by its members.
