Summary

Creates a NOAA-led National Integrated Heat Health Information System (NIHHIS) and an interagency committee to coordinate Federal efforts to reduce heat-related health risks. The law requires a public 5-year strategic plan (first due within two years), open sharing of NIHHIS data and tools, stewardship by NOAA’s National Centers for Environmental Information, and authorizes $5 million per year for FY2025–2029 to support the system and committee operations.

Key Points

• Creates a NOAA-hosted National Integrated Heat Health Information System (NIHHIS) to improve heat-health data, warnings, research, and tools.
• Establishes an interagency committee to coordinate Federal activities, consult stakeholders (including Tribal governments), and produce a public 5-year strategic plan.
• Requires the first strategic plan within 2 years of enactment and updates every 5 years thereafter.
• Mandates that NIHHIS data and metadata be made fully and openly available consistent with federal records and evidence rules.
• Assigns stewardship and staffing of NIHHIS to NOAA’s National Centers for Environmental Information and directs NOAA research support.
• Authorizes $5 million per year for FY2025–2029 to support NIHHIS operations and interagency coordination.
• Provides statutory definitions for terms like extreme heat, heat event, heat-health, planning, preparedness, and Tribal government to guide implementation.
• Focuses on coordination, data sharing, and science-based tools rather than imposing mandates on states or localities.
