From June 20-21, the Center for Climate and Security (CCS) gathered its 2023-2024 Climate Security Fellows in Washington, DC as a culmination of their ten-month program. During this first-ever Climate Security Fellowship Summit, attendees reflected on the program experience and had a chance to engage with distinguished panelists from Department of Defense (DoD) National Security Council (NSC), and State Department backgrounds, and heard career advice from former fellows and CCS staff who now occupy key diplomatic, defense, and peacebuilding roles. Fellows also had a chance to learn more about the Council on Strategic Risk’s other ecological, nuclear, and biological risk fellowships and socialize with the broader fellowship community.

The Fellows represent backgrounds including security cooperation, water diplomacy, climate adaptation and resilience, public health, data science and international relations. From September 2023 through June 2024, participants worked through a curated climate security curriculum covering food and water security, conflict and instability, migration and justice, the energy transition, health, finance, military and intelligence services, strategic competition, and science communication. Fellows then participated in interdisciplinary seminars on each theme with CCS staff and distinguished experts, whose experiences span development, defense, diplomacy, intelligence analysis, climate science, academia, and the private sector (see below).
The Climate Security Fellowship supports a key element of CCS’s theory of change–cultivating a climate-strong national security workforce. As they conclude their fellowship, participants are better equipped to ask and answer the vexing, interdisciplinary questions posed by climate change for peace and security. Looking ahead, CCS aims to continue expanding and strengthening its fellowship programs and alumni community.
