The bill funds and coordinates a national heat-health information system that substantially improves warnings, planning, and data access to protect vulnerable people, while introducing modest federal costs, administrative complexity, and risks of uneven implementation and legal/definition gaps.
Seniors, people with disabilities, low-income people, children, and communities (urban and rural) will get better, more coordinated heat warnings and forecasts through a funded National Integrated Heat Health Information System, reducing heat-related illnesses and deaths.
State and local health agencies, hospitals, and researchers gain clearer federal leadership and a coordinated 5-year strategic plan with recurring briefings and improved data sharing to better target resources and align heat-health activities.
Clear, science-based definitions of 'extreme heat' (including humidity, solar exposure, and wind) enable more accurate risk assessments, early-warning systems, and multi-timescale mitigation planning by emergency managers and planners.
Rural and under-resourced communities and low-income populations may receive uneven benefits because local capacity to use new tools and data varies.
The program depends on agencies taking action and on short-term funding (FY2025–2029); if funding or agency follow-through is insufficient or not sustained beyond 2029, long-term effectiveness and stability are at risk.
Federal administrative and operational costs (about $25 million total over five years) create a modest taxpayer burden and could crowd out other priorities.
Based on analysis of 5 sections of legislative text.
Creates a NOAA-based National Integrated Heat Health Information System and interagency committee, requires a 5-year strategic plan, open data access, and authorizes $5M/year for FY2025–2029.
Official title: To reduce the health risks of heat by establishing the National Integrated Heat Health Information System within the National Oceanic and Atmospheric Administration and the National Integrated Heat Health Information System Interagency Committee to improve extreme heat preparedness, planning, and response, and for other purposes.
Introduced June 4, 2025 by Yassamin Ansari · Last progress June 4, 2025
Creates a federally coordinated system to reduce heat-related health risks by establishing a National Integrated Heat Health Information System (NIHHIS) at NOAA and an interagency committee to coordinate federal activities, plan research, share data openly, consult stakeholders, and improve forecasts, warnings, and tools. It directs NOAA to host and archive open heat data and requires a strategic plan; Congress is authorized $5 million per year for FY2025–2029 to support the system and committee operations.
