Protecting the United States Against Extreme Heat

Extreme heat is swiftly 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 and productivity, including U.S. global competitiveness. Americans recognize the problem. The negative health, social, and economic effects of extreme heat have become a common, lived experience of broad sectors of the American public, cutting across income, racial, ideological, and geographic lines. Americans expect action and know there are solutions. As extreme heat events have become far more politically salient across the United States, they have raised popular expectations and prompted state, municipal, and local leaders, working in partnership with universities, civil society organizations, businesses, and philanthropies, to seek pragmatic solutions that draw support across the partisan divide. Debates are now unfolding on which interventions are the most impactful and cost effective, and how best to expedite their implementation.

The CSIS Bipartisan Alliance for Global Health Security’s Working Group on Climate and Health will convene on extreme heat and health on Wednesday, November 5, 2025, from 3:00 to 5:00pm ET. The occasion will launch the Alliance Working Group’s report Three Steps to Protect the United States Against Extreme Heat. In its report, the Working Group lays out three recommendations: the launch of a high-level bipartisan panel, the establishment of a data consortium, and the strengthening of essential core federal functions.

This event is made possible by the generous support of GSK and the Wellcome Trust.
