The Center for Climate and Security (CCS), an initiative of the Council on Strategic Risks, has opened applications for the 2026–2027 Gordon R. Sullivan Climate and Ecological Security Fellowship. The professional development programme is designed for emerging professionals working at the intersection of climate change, environmental issues, and national or international security. Named in honour of General Gordon Sullivan, a former U.S. Army leader and early advocate for integrating climate and environmental considerations into national security planning, the fellowship seeks to cultivate the next generation of public servants and professionals working on climate-security challenges. The unpaid, part-time fellowship will run from October 2026 through July 2027, combining virtual learning, expert engagement, structured discussions, and independent work. About the Sullivan Fellowship The fellowship is a professional development programme that provides participants with an opportunity to deepen their understanding of the relationship between climate change, ecological challenges, and security. Fellows will participate in monthly two-hour virtual sessions featuring guest speakers, small-group activities, discussions, assigned readings, and other curriculum-based activities. The programme will examine a broad range of emerging climate-security issues, including: Food and water security Climate-related migration Climate adaptation and resilience The role of militaries and intelligence services Disinformation and democracy The global energy transition Technology and artificial intelligence Strategic competition Climate intervention and geoengineering Through these sessions, fellows will have opportunities to engage with experts and peers while developing knowledge relevant to careers in public service, climate policy, environmental security, and national or international security.
