119th (2025–2027)
H.R. 3704
This bill establishes a coordinated federal system to address extreme heat and its health impacts on Americans. It creates two main structures: the National Integrated Heat Health Information System (NIHHIS) within the National Oceanic and Atmospheric Administration to improve heat forecasts, warnings, and data sharing, and an interagency committee led by representatives from 16+ federal agencies—including NOAA, the Centers for Disease Control and Prevention, FEMA, and the Department of Defense—to align federal heat preparedness and response efforts. The bill requires the committee to develop a 5-year strategic plan within two years outlining how agencies will improve data collection on heat-related illnesses, coordinate research, and provide actionable information to the public and state and local governments. The legislation authorizes $5 million annually from 2025 through 2029 for NIHHIS operations and committee activities, with all collected data made publicly available to support the system's goals of reducing heat-related health risks and economic impacts.
