The Ten Across Resilience Network convened in Jacksonville, Florida, in April to share strategies from their communities—the hottest in the nation—for mitigating the mortality and economic loss caused by extreme heat, and to identify common obstacles to both long-term planning and immediate response. Representatives from the Federation of American Scientists (FAS) joined the exercise to discuss and document the findings.  

With co-author Dr. Melissa Guardaro, Senior Global Futures Scientist for ASU’s Global Futures Lab, FAS’s Grace Wickerson has drafted a set of policy recommendations for all levels of government and non-governmental actors, “Framework for a Heat-Ready Nation.” This document draws heavily upon the recommendations, challenges and successes raised by Ten Across participants and outlines a series of steps that can be taken to protect people and their livelihoods from rising temperatures nationwide.  

In this episode, Grace walks us through the five high-priority measures defined in the report;  how these points were determined and what it will take to see them carried out. A scientist recognized for their policy advocacy work by last month’s 2025 Grist 50 list, Grace discusses the importance of decisions based on sound science, and how to move forward even as most federal climate policy is rolled back.
