Extreme heat is becoming an urgent priority in the United States and beyond. The threat posed by extreme heat has become a matter of national security, impacting U.S. military readiness, while threatening economic growth, productivity, and global competitiveness. The negative health, social, and economic effects of extreme heat have become a common, lived experience among broad sectors of the American public, cutting across income, racial, ideological, and geographic lines. As extreme heat events have become more politically salient, they have raised popular expectations and prompted state, municipal, and local leaders, working in partnership with universities, community groups, businesses, and philanthropies, to seek pragmatic solutions that draw support across the partisan divide. In the fall of 2024, the CSIS Bipartisan Alliance for Global Health Security launched a working group to develop policy recommendations for addressing climate-related health challenges that have implications for national security. The working group argues that three actions lay the foundation of a strategy to better protect Americans, strengthen preparedness, and protect U.S. national interests: the launch of a high-level bipartisan panel, the establishment of a data consortium, and the strengthening of essential core federal functions. In combination, these measures will make the United States stronger, more secure, and more prosperous.
