more that may have heat-health implications. 
(5) HEAT-HEALTH.—The term ‘‘heat-health’’

SEC. 3. FINDINGS. 
Congress makes the following findings: 
(1) Extreme heat events have been the leading 
cause of weather-related death in the United States 
over the last 30 years, according to the Centers for 
Disease Control and Prevention and the National 
Weather Service. 
(2) The fourth National Climate Assessment, 
mandated by the Global Change Research Act of 
1990 (15 U.S.C. 2921 et seq.), finds that during the 
next few decades, annual average temperature over 
the contiguous United States is projected to increase 
by a further 2.2°F relative to current temperatures, 
regardless of future scenarios. The National Climate 
Assessment projects that the frequency and intensity 
of extreme heat events will increase in the future as 
global temperature increases. 
(3) Exposure to extreme heat can cause acute 
heat-related illnesses, such as heat stroke, which al-
ready result in more than 65,000 emergency room 
visits each year and exacerbate respiratory and car-
diovascular illnesses. 
(4) Heat poses the greatest health risks for 
adults older than 65 years of age, pregnant people, 
young children, low-income communities, urban com-
munities, communities with low air conditioning

prevalence, socially isolated individuals, people with 
mental or physical disabilities, people with under-
lying medical conditions, agricultural or other out-
door workers, workers without sufficient access to 
cooling, athletes, incarcerated individuals, people ex-
periencing homelessness, and military personnel. 
(5) Extreme heat is significantly associated 
with serious adverse pregnancy outcomes across the 
United States. Those adverse pregnancy outcomes 
disproportionately impact Black mothers. 
(6) Heat exposure is an issue of environmental 
justice, as people living in low-income communities, 
communities of color, and Tribal nations face a 
number of interacting factors that render them more 
vulnerable to extreme heat. 
(7) The impacts of heat on human health are 
more severe in urban areas where land surface prop-
erties create an urban heat island, particularly in 
neighborhoods with limited availability of or access 
to green spaces, shade, and tree cover, due to higher 
density of building structures and more vehicular 
traffic. 
(8) Limited availability of tree cover and higher 
temperatures are correlated with low-income neigh-
borhoods in urban areas. In Richmond, Virginia,

Baltimore, Maryland, and Washington, DC, re-
searchers found that risk of exposure to extreme 
heat is disproportionately distributed to communities 
of color in patterns associated with segregation and 
redlining. 
(9) Researchers have found that few commu-
nities in the United States have sufficient climate 
and health information, guidance, and resources for 
heat planning, preparedness, and response. 
(10) The risks associated with extreme heat 
have complex interactions and impacts, and the 
management 
of 
those 
risks 
requires 
a 
transdisciplinary approach. 
(11) Regions, communities, and populations 
that face the greatest health consequences of ex-
treme heat often may experience the lowest heat risk 
perceptions, have limited incentives, or have access 
to the fewest resources for responding to extreme 
heat, and as such, may be less likely to take pre-
cautions. 
(12) Research on the impacts of extreme heat 
on human health and the effectiveness of solutions 
under varying climate, social, and other contexts is 
stymied by a lack of access to reliable, timely health 
observations and surveillance due to proprietary data

rights, expense, privacy and security concerns, incon-
sistent reporting of health outcomes and contribu-
tory factors, poor data integration and interoper-
ability, few incentives and little systematic coordina-
tion to address those problems, and a lack of ade-
quate climate observation, modeling, and assessment 
in rural, urban, indoor, and occupational settings. 
(13) Integrated climate and health research and 
information, when developed in a collaborative, 
transdisciplinary manner, can inform long- and me-
dium-range scenario-based planning and decision 
making to protect communities with environmental 
justice concerns and other populations from extreme 
heat, reduce exposure to extreme heat, and address 
factors that increase vulnerability. 
(14) The Federal Government has developed, 
and should maintain, preserve, or reinstate, various 
science-informed heat-health tools for communities 
with environmental justice concerns, workers, em-
ployers, and the public to understand heat risk and 
resources, including the Centers for Disease Control 
and Prevention Heat and Health Tracker, the Office 
of Climate Change and Health Equity Climate and 
Health Outlook, the National Weather Service 
HeatRisk portal, the National Emergency Medical

Services Information System Heat-related Emer-

Dashboard, and the Low-Income Home Energy As-
sistance Program and Extreme Heat website. 
(15) Increased heat can have cascading and 
compounding impacts across and among sectors in-
cluding energy, food supply and quality, transpor-
tation, 
housing, 
infrastructure, 
hospital 
and 
healthcare delivery, and education, all of which af-
fect health and well-being. 
(16) Heat action plans and early warning sys-
tems can reduce heat-related morbidity and mor-
tality by clearly identifying roles and responsibilities 
as well as evidence-based actions and thresholds to 
enhance preparedness, and by promoting behavior 
changes and actions taken by local governments, 
communities, and individuals through awareness and 
increased risk perception among those most vulner-
able to the health impacts of heat.
