Information manipulation is increasingly recognized as a contributor to climate risks. 2025 saw landmark academic assessments on the topic, as well as the first action on climate information integrity at a UN climate summit. Meanwhile, bad actors take advantage of opportunities to propagandize, sow confusion, and undermine trust as the impacts of climate change intensify and the stakes of policy action grow. These mutually reinforcing challenges jeopardize security and democracy, especially amid volatile geopolitics, rapid change in the technology and media landscape, and US federal reversals on climate policy and information integrity. 

This raises questions for a range of US actors amid intensifying extreme weather. How can state and local officials build resilience and respond to emergencies when facing an unsupportive federal government and global, minimally regulated information threats? What are the implications for US military disaster relief and readiness when information manipulation threatens political cohesion and civilian communities? How can journalism or tech policy serve climate security by mitigating mis/disinformation? And how can academia, civil society, and community groups better collaborate to exchange information and expertise? 

The Center for Climate and Security (CCS) recently completed a foresight exercise in Florida to explore these questions. Co-hosted by the University of Miami’s Climate Resilience Institute, the event brought together a diverse mix of expertise, including local resilience and emergency management, national security and foreign policy, communications and information integrity, social and natural sciences, and local climate education and activism. Participants heard from senior homeland security and defense speakers, then engaged in a facilitated scenario exercise exploring a plausible extreme weather, information, and national security crisis in Florida. The discussion highlighted several key themes.
