Management and Disaster
The National Oceanic and Atmospheric Administration (NOAA) reported that several areas of
Recovery
the United States experienced record heat during the summer of 2023. In August alone, 130

million Americans in 22 states were subject to heat alerts. Arizona and New Mexico also
experienced their hottest months on record, with temperatures exceeding previous highs by

nearly two degrees Fahrenheit. Previously, extreme heat during the summers and autumns of
2021 and 2022 had set heat records in multiple states. Government and academic experts generally expect these trends to
continue as the planet warms; the U.S. Global Change Research Program’s Fifth National Climate Assessment (2023)
reported that “it is very likely that heatwaves will increase in frequency, severity, and duration as warming continues.”
Meteorologically, extreme heat is assessed relative to each specific climate. The Centers for Disease Control and Prevention
(CDC) defines extreme heat as air temperature that is much hotter and/or humid than average for a particular time and place.
For the purposes of emergency preparedness, the Federal Emergency Management Agency defines extreme heat as a period
of temperatures above 90 degrees Fahrenheit and high humidity for at least two to three days. During these events, affected
communities frequently report excess deaths, overwhelmed health care systems and increased rates of hospitalization, and
power supply strains that may affect access to air-conditioning or other services. Socially vulnerable populations, including
individuals with medical conditions and disabilities, children, older adults, unhoused persons, agricultural and other outdoor
workers, lower-income persons, people of color, incarcerated persons, and persons without air-conditioning, may be at
particular risk of heat-related illness or death.
CDC and NOAA report that extreme heat is one of the leading weather-related causes of death in the United States. CDC
identified 10,527 heat-related deaths from 2004 to 2018 in the United States (averaging 702 deaths annually). Annual
fatalities in more recent years are higher: in 2022, the CDC reported that 3,066 heat-related deaths occurred between 2018
and 2020 (averaging 767 per year), and in 2023, the agency reported that 1,600 heat-related deaths occurred in 2021 alone.
Given actuarial challenges with attributing deaths to heat, researchers estimate that the actual number of heat-associated
deaths is higher, ranging from 1,300 to 5,000 annually in the United States in recent decades.
Given these impacts, state, local, tribal, and territorial governments (SLTTs) have taken an interest in responding to extreme
heat events. CDC and the Environmental Protection Agency have highlighted emergency response measures that
governments and communities may undertake to protect residents, including:
• developing heat health action plans;
• communicating risks to the public;
• cancelling outdoor events;
• expanding surveillance of health effects;
• increasing emergency medical staff;
• expanding services and distributing water to vulnerable populations;
• providing emergency energy assistance; and
• opening cooling centers.
Some SLTTs have taken additional measures, such as issuing rules or guidance requiring rest, water, and access to
climate-controlled environments for workers, students, and other people. Some SLTTs have also undertaken long-
term measures to reduce the risks that extreme heat poses to human health, including measures to reduce the effect
of urban “heat islands” – or areas where buildings, roads, and other built features absorb and intensify heat. Some
experts and stakeholders have raised concern that nonfederal measures do not provide sufficient protection to
affected populations.
The federal government has also taken action to manage risks associated with extreme heat, including (1) establishing the
National Integrated Heat Health Information System, an interagency information system providing data and tools to protect
the public from heat; (2) launching Heat.gov, a centralized webpage on federal resources to help the public understand, plan

for, and manage the risks of extreme heat; and (3) creating an Interagency Working Group on Extreme Heat, which is to
publish a National Heat Strategy. Congress has also introduced several bills authorizing assistance to nonfederal entities to
mitigate and/or respond to the health impacts of extreme heat events.
This report summarizes federal resources that may be available to facilitate emergency preparedness and response to
extreme heat, as well as considerations for Congress on the federal government’s past response to extreme heat and
challenges adapting existing federal relief programs to extreme heat episodes, among other topics.

Introduction
In recent years, parts of the United States have experienced record episodes of extreme heat. For
instance, in 2021, a historic “heat dome” set temperature records in multiple states,1 and became
the deadliest weather-related incident in recorded Washington state history.2 Extreme heat across
the United States during September 2022 broke nearly 1,000 heat records.3 In the wake of some
of these incidents, several governors (including those in Louisiana, Arizona, California,
Washington, and Oregon) declared emergencies for extreme heat.4 According to the National
Aeronautics and Space Administration (NASA), July 2023 was the globe’s hottest month in 174
years of records, and unusual heat continued to set records in the fall.5 NASA further reported that
the summer of 2023 was the hottest summer—and 2023 the hottest year—recorded to date (see
Figure 1).6 Government authorities and scientific organizations expect the United States to
experience extreme heat episodes of greater frequency, duration, and intensity due to climate
change, among other factors.7

Congress has recently taken action to respond to the threat that extreme heat poses to U.S. public
health. Several bills in the 118th Congress would authorize assistance to nonfederal entities to
mitigate and/or respond to the health impacts of extreme heat events (e.g., H.R. 4953/S. 2654;
H.R. 4733/ S. 2383; H.R. 4314; H.R. 3965; H.R. 2945/S. 1379; H.R. 565/S. 180). Others (e.g.,
H.R. 4256/S. 2081) would introduce heat-related requirements for federal program participants.8
The 118th Congress has further examined the threat extreme heat poses to communities and the
built environment through several hearings.9
The executive branch has also responded to extreme heat. Since 2015, the National Oceanic and
Atmospheric Administration (NOAA) and the Centers of Disease Control and Prevention (CDC)
have led the National Integrated Heat Health Information System (NIHHIS), an interagency
information system “to develop and provide actionable, science-based information to help protect
people from heat.”10 In 2022, the Administration of Joe Biden launched Heat.gov, where NIHHIS
shares tools and research to support planning, mitigation, and response to extreme heat.11 In 2021,

8 Other heat-related legislation concerns private business heat standards (e.g., H.R. 4897/S. 2501) or to provide
assistance to businesses with losses due to extreme heat, among other weather events (e.g., H.R. 662/S. 180).

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

President Biden announced new initiatives in several federal agencies to respond to the health
impacts of extreme heat, including the establishment of the Interagency Working Group on
Extreme Heat and the Department of Health and Human Services (HHS) Office of Climate
Change and Health Equity.12 In July 2023, President Biden additionally announced that federal
partners were at work on a National Heat Strategy in consultation with local and tribal officials to
understand how the federal government could assist communities coping with extreme heat.13
This report provides an overview of the health effects of extreme heat on humans, existing federal
resources available to respond to such consequences, and measures some nonfederal governments
are taking in response to extreme heat.14 The final section offers considerations for Congress
regarding the past and present role of the federal government in response to episodes of extreme
heat, and challenges in adapting existing federal authorities to the threat of extreme heat.
Defining Extreme Heat
What constitutes “extreme” heat meteorological y is relative to each region’s climate.15 Federal agencies have
defined extreme heat in various ways.
For the purposes of helping communities prepare, the Federal Emergency Management Agency (FEMA) explains
that extreme heat may be general y defined as a period of temperatures above 90 degrees Fahrenheit and high
humidity for at least two to three days.16
For the purposes of understanding the impacts of extreme heat on human health, the Environmental Protection
Agency (EPA) defines an extreme heat event or a heat wave as “a period of two or more consecutive days when
the daily minimum apparent temperature (the actual temperature adjusted for humidity) in a particular city
exceeds the 85th percentile of historical July and August temperatures (1981–2010) for that city.”17 The EPA

analyzes historic trends in extreme heat by analyzing the frequency, duration, intensity, and season length of
extreme heat episodes.18
Separately, the National Oceanic and Atmospheric Administration (NOAA) has established a “heat index”—a
combined measure of temperature and relative humidity designed to capture how heat feels to the human body.19
NOAA generally issues excessive heat warnings, advising individuals to take protective actions, when the
maximum heat index is expected to exceed 105 degrees Fahrenheit for at least two days and night time air
temperatures are not expected to drop below 75 degrees Fahrenheit.20 However, the agency notes that “these
criteria vary across the country, especial y for areas not used to extreme heat conditions.”21
The CDC defines extreme heat as “summertime temperatures that are much hotter and/or humid than average,”
noting that extreme heat “depends on what’s considered average for a particular location at that time of year.”22
Extreme Heat: Snapshot of Health Effects on
Humans
Since 2021, U.S. communities affected by extreme heat events have experienced heat-related
deaths,23 spikes in heat-related emergency room visits that overwhelm health care systems,24 and
power supply strains,25 among other consequences. In some cases, insufficient cooling and/or

evacuations and compounded health risks.26 Some experts have found that extreme heat
additionally poses risks to student learning, food security, and other measures of social welfare.27
Socially vulnerable populations face particular risk of heat-related illness or death. Such
populations include individuals with medical conditions and disabilities, as well as children, older
adults, unhoused persons, agricultural and other outdoor workers, marginalized racial groups,
pregnant persons, lower-income persons, incarcerated persons, persons without air-conditioning
due to access or affordability, and athletes.28 Certain living situations—including living in urban
environments, living alone, or living on higher floors of buildings—have also been found to
increase risk of heat-related death.29
The CDC and the National Weather Service report that extreme heat is one of the leading
weather-related causes of death in the United States.30 CDC identified 10,527 heat-related deaths
from 2004 to 2018 in the United States based on information reported on death certificates
(averaging approximately 700 deaths annually).31 Annual fatalities in more recent years are
higher. In 2022, the CDC reported that 3,066 heat-related deaths occurred between 2018 and 2020
(averaging 767 per year), and in 2023, the agency reported that 1,600 heat-related deaths occurred
in 2021 alone.32 Other scholars and methods estimate that in recent decades, the United States has

experienced 1,300 to 5,000 heat-related deaths annually.33 Heat-related death counts, including
CDC figures, are generally understood to underestimate the true number of deaths linked to heat
events due to inconsistency in diagnosis and reporting on death certificates.34 The National
Climate Assessment anticipates that the number of heat-related fatalities in the United States will
increase unless greenhouse gas emissions decline and adaptation measures are implemented.35
Certain demographic trends (including population aging) may increase the risk of heat-related
illness and death.36
Managing Extreme Heat: Nonfederal Authorities and Efforts
The CDC37 and EPA38 highlight response measures that state, local, tribal, and territorial
governments (SLTTs) and communities may undertake to protect residents and manage episodes
of extreme heat, including:
• developing heat health action plans;39
• communicating risks to the public, including through “early warning” systems;40
• suspending outdoor events;
• expanding surveillance of health effects;
• increasing emergency medical staff;

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

• expanding services and distributing water to vulnerable populations;41
• providing emergency energy assistance;42 and
• opening cooling centers.43
Experts have found that some cities that executed such measures observed fewer casualties and
hospitalizations during extreme heat.44 Some affected state and local governments have taken
additional measures, including proposing and sometimes adopting emergency protocols or safety
measures for businesses,45 elementary and secondary schools,46 and other facilities47 to protect
health and safety in the workplace and greater public. Other state and local governments provide
transportation to cooling centers or other safe areas to individuals at risk,48 which may reduce
access barriers for some vulnerable populations.49 Several states require or advise utility
companies to suspend service disconnections during specified episodes of extreme heat.50 In the
past several years, a handful of cities have established offices and positions dedicated to the issue

of extreme heat—for example, the City of Phoenix’s Office of Heat Response and Mitigation.51 In
March 2024, the State of Arizona became the first to appoint a Chief Heat Officer.52
In addition to urgent response measures, some state and local agencies have also identified and
implemented long-term projects to reduce health risks posed by extreme heat, including:
• Providing shade cover (including tree canopy) for pedestrians, particularly in urban
areas;53
• Providing chilled drinking water access in schools and public places;54 and
• Increasing tree and vegetative cover over built surfaces (e.g., roofs and pavement).55
These strategies may particularly benefit urban “heat islands”56 where built surfaces absorb and
re-emit heat in the absence of cooling, shade-creating vegetation.57
Gaps in Nonfederal Authorities and Resources for Extreme Heat Response
Despite some of the recent initiatives discussed above, most states do not have specific laws,
standards, or plans addressing extreme heat.58 Identified gaps or disparities in relevant state and
local emergency procedures and authorities include:
• Lack of a clearly identified party responsible for extreme heat preparedness,
response, and mitigation;59

• Lack of insurance or other financial means to cover costs incurred by
governments or community healthcare systems for emergency response during an
episode of extreme heat;60
• Insufficient focus on heat safety and a patchwork of relevant standards;61 and
• Energy disconnection policies that vary widely across state and local
governments, posing risks that individuals may face disconnection—and lack of
access to climate control—during an episode of extreme heat.62
Federal Financial Assistance by Agency
The next section identifies select federal assistance potentially available through the Department
of Homeland Security (DHS), HHS, the Department of Housing and Urban Development (HUD),
the Department of Agriculture (USDA), the Department of Commerce, and other authorities for
certain extreme heat response and mitigation costs incurred by SLTTs, eligible community
organizations (e.g., nonprofit hospitals), and individuals. However, none of the federal assistance
programs listed below were specifically designed to provide assistance for extreme heat. Given
evolving and flexible program and grant guidelines, the information provided in this report may
not be comprehensive. Program applicability to each applicant or incident may vary.
Federal assistance for other costs related to extreme heat (e.g., infrastructure improvements,
assistance to individual survivors) may be available from other programs and agencies. Selected
programs through the Department of Energy to assist with electricity reliability and efficiency
that may reduce risks related to extreme heat events are summarized in Appendix A.63 Technical
assistance may also be available to communities for the purposes of extreme heat emergency
response, such as that provided by the EPA to develop cooling centers in public school facilities.64
Department of Homeland Security—FEMA
FEMA’s response, recovery, and Hazard Mitigation Assistance (HMA) programs could provide
funding to address risks from extreme heat.65
FEMA may provide assistance for heat-related response costs if the President issues an
emergency or major disaster declaration for extreme heat under the Robert T. Stafford Disaster

Relief and Emergency Assistance Act (the Stafford Act; P.L. 93-288, as amended).66 However,
past Presidents have denied all requests for Stafford Act declarations for extreme heat:67
• In 1980, Governor Joseph Teasdale of Missouri requested two major disaster declarations
for extreme heat and drought. A FEMA representative reported that the initial request was
denied because “‘the severity and magnitude of the situation did not warrant a declaration
under the Disaster Relief Act’ and explained that the severity must be beyond the ability
of state government to handle before the federal government [would] step in.”68
• In 1995, Governor Jim Edgar requested a major disaster declaration for a
Chicago heat wave that had directly caused over 500 deaths (scholars have since
put the number above 700).69 FEMA, state, and local officials conducted a
preliminary damage assessment that tallied costs incurred due to the fatalities and
emergency response costs, as well as some structural damage to O’Hare
International Airport.70 President Clinton denied the request; FEMA’s then-
Administrator explained that the event was “not of a severity and magnitude”
required of a major disaster.71
Additionally, governors have requested Stafford Act declarations for incidents caused or
exacerbated by extreme heat. For example, in October 2022, Governor Gavin Newsom requested
a major disaster declaration for the 2022 heat dome and resulting wildfires.72 FEMA denied the
request, 73 and subsequent appeal,74 finding that “the damage from this event was not of such
severity and magnitude” to warrant a major disaster declaration.75 FEMA further reported to CRS
that the agency does not consider the request to be for the heat dome, as the wildfires caused the
damage for which the state sought assistance and “FEMA precedent is to evaluate discrete events
and impacts, not seasonal or general atmospheric conditions.”76

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

Despite this history, past Presidents and recent FEMA officials have affirmed the potential
relevance of the Stafford Act to extreme heat. President George W. Bush did declare emergencies
for several states for power outages in August 2003 following supply strains attributed, in part, to
air-conditioning use during extreme heat.77 In September 2023, FEMA Administrator Deanne
Criswell testified before Congress that the Stafford Act could be activated to provide assistance
for extreme heat if warranted, after being asked whether the statue required amending for this
purpose:
The Stafford Act does not need to be amended to include extreme heat. We base our
decisions on a number of factors, mostly on what—does it exceed the capacity of the state
and local jurisdictions. If the response to an extreme heat incident exceeds the capacity of
a state and local jurisdiction, they are very open to submit a disaster declaration request.
And we will consider that based on whether or not it exceeds their capacity.78
Five FEMA programs could offer assistance for costs associated with extreme heat response, if
authorized.
Public Assistance (PA)79
CRS Expert: Erica Lee
• FEMA’s Public Assistance program provides financial and direct assistance (e.g.,
materials, operational support, personnel) to SLTTs and eligible nonprofits when
authorized by the President through a Stafford Act declaration.80 Subject to
agency discretion, FEMA may provide reimbursement or direct assistance for
emergency protective measures, including “sheltering,” which could potentially
include cooling centers, as well as emergency food, water, or medical care, and
risk communication.81

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

Individual Assistance (IA)
CRS Expert: Elizabeth Webster
• When the Individual Assistance program is authorized by the President pursuant
a Stafford Act declaration, FEMA may provide financial assistance for housing
and/or other needs (referred to as Other Needs Assistance or ONA) to disaster
survivors through the Individuals and Households Program (IHP). In certain
cases, FEMA may be able to provide Assistance for Miscellaneous Items, a form
of IHP-ONA, to eligible individuals to reimburse the costs of purchasing new AC
units and/or electrical fans to assist their disaster recovery. Other forms of IHP
assistance only permit FEMA to provide funding to repair or replace an HVAC,
air conditioning (AC) units, and/or electric fans that were owned prior to, and
were damaged by, the declared emergency or major disaster, including through
Home Repair Assistance and Personal Property Assistance.82
Hazard Mitigation Grant Program (HMGP)83
CRS Expert: Diane Horn
• Following a declaration of any Stafford Act major disaster84 or Fire Management
Assistance Grant (FMAG),85 HMGP is awarded as a formula grant to states based
on estimated federal assistance per declaration or FMAG, subject to a sliding
scale.86 Funds may be used for eligible activities irrespective of the hazard or
area for which the grant was awarded. For example, while one county may use
funding allocated following a flooding incident in one county, another county
could use funding for eligible mitigation measures of extreme heat.87 FEMA has
clarified that HMGP can be used for mitigation planning and projects that reduce
risk of extreme heat.88

82 For more information on assistance FEMA may provide to individuals and households through the Individuals and
Households Program (IHP) that may help address the threat of extreme heat, see CRS Insight IN11988, FEMA IHP
Assistance for Extreme Heat: Considerations and Limitations, by Elizabeth M. Webster. For specific assistance
requirements, including related to IHP program eligibility and limitations, see FEMA’s Individual Assistance Program

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

Building Resilient Infrastructure and Communities (BRIC)89
CRS Expert: Diane Horn
• The Building Resilient Infrastructure and Communities (BRIC) program provides
financial and direct assistance (e.g., personnel) to SLTTs undertaking risk
mitigation activities to reduce the threat of future disaster-related losses of life
and property. BRIC is a pre-disaster mitigation grant and, as such, does not
require a declaration. It is awarded competitively to communities on an annual
basis. FEMA guidance notes that BRIC funds may be available to cover the cost
of plans to mitigate the effects of extreme heat, providing emergency power to
cooling centers, and implementing long-term building projects to reduce the risk
of extreme heat (e.g., providing shade in public places).90
Emergency Management Performance Grant (EMPG)91
CRS Expert: Shawn Reese
• Emergency Management Performance Grant (EMPG) funds are available on a
formula basis to all states, territories, and the District of Columbia, and do not
require a Stafford Act declaration.92 EMPG provides federal funds to states to
assist SLTTs in preparing for all hazards in accordance with the National
Preparedness System.93 FEMA says the EMPG program for FY2023 will support
the agency’s focus on preparedness for all hazards, including evolving threats and
risks associated with climate change.94 As in 2022, the 2023 EMPG Notice of
Funding Opportunity states that “emergency managers must learn to manage and
support climate-related emergencies such as drought and extreme heat.”95

to prepare for and respond to public health emergencies.96 In addition to providing technical
assistance and education, ASPR also provides funds through grants and cooperative agreements.
While these funds are generally designed to bolster the preparedness and response capacities of
recipients, they can sometimes be used to respond to emergencies. Specifically, certain ASPR
programs may cover emergency response costs associated with extreme heat.
Hospital Preparedness Program97
CRS Expert: Hassan Sheikh
• The Hospital Preparedness Program (HPP) provides assistance to all 50 states, eight
territories and freely associated states, three metropolitan areas and the District of
Columbia. Recipients are to use these funds to support health care preparedness
capabilities for disasters and the development and enhancement of health care coalitions
within their jurisdictions. These funds can be used to support preparedness efforts for
extreme weather events, including extreme heat.98 In certain instances, these funds can
also be used to support emergency response efforts.99
Centers for Disease Control and Prevention (CDC)
Recipients of certain CDC grants may use some funds to prepare for or respond to extreme heat.
These funds are generally designed to increase public health planning or preparedness capacity.
However, in certain circumstances, funds can be used for response costs. Depending on the grant,
funded activities can include emergency planning, health communication, data surveillance and
analysis, and efforts to identify and assist at-risk individuals. The following provides an overview
of selected relevant CDC grant programs.

community needs related to heat events, if compliant with one of the program’s
three national objectives and all relevant requirements.120
CDBG—Disaster Recovery (CDBG-DR)121
CRS Expert: Joe Jaroscak
• Congress has provided for supplemental appropriations using CDBG authorities
for disaster recovery (CDBG-DR), or in response to other emergency events.
Emergencies may potentially include extreme heat. In February 2018, Congress
dedicated funds to mitigate against future disaster risk (CDBG-MIT) following
some incidents; this could serve as a model for extreme heat mitigation
resilience.122
The Indian Community Development Block Grant (ICDBG)123
CRS Expert: Joe Jaroscak
• The Indian Community Development Block Grant (ICDBG) provides economic
development and urgent needs funding to federally recognized tribal nations and
Alaska Native villages. ICDBG funding is awarded in two categories: (1)
competitive community and economic development grants allow for a variety of
uses, including potentially extreme heat mitigation; and (2) noncompetitive
imminent threat grants address issues posing an urgent threat to the public health
or safety of tribal residents, which could also respond to extreme heat incidents
or their aftermath.

Department of Commerce
Economic Development Administration (EDA)—Disaster Recovery129
CRS Expert: Julie Lawhorn
• In response to some major disasters and emergencies, Congress has provided
supplemental funding for long-term disaster recovery for selected incidents under
the Economic Development Administration’s (EDA’s) economic adjustment
assistance (EAA) program. The EAA program supports a variety of activities,
including expenses related to disaster relief, the restoration of infrastructure,
flood mitigation, and other forms of assistance for specific areas. EDA directs
prospective applicants to demonstrate how projects may facilitate resilience to
future disruptions including extreme heat. For instance, funding could be used for
the development and construction of resilient infrastructure and buildings to
mitigate future risk and vulnerability, including from impacts of climate
change.130
Federal Regional Commissions and Authorities131
CRS Expert: Julie Lawhorn
• Congress authorized eight federal regional commissions and authorities to
address instances of major economic distress in certain defined socioeconomic
regions. Of the eight authorized federal regional commissions and authorities,
five could be considered active and functioning as of the date of publication:

(NBRC);135 and Southeast Crescent Regional Commission (SCRC).136 As
chartered federal-state partnerships, the federal regional commissions receive
appropriated funds, which they sub-allocate for community and economic
development purposes in their respective service areas. These funds are generally
flexible, and can be used to address a variety of community and economic
development purposes, including pre- and post-disaster hazard mitigation uses
related to extreme heat or other climate-related issues. Previously, grant funding
has been used to respond to natural disasters and the COVID-19 pandemic.
Defense Production Act of 1950 (DPA)137
CRS Experts: Luke Nicastro, Alex Neenan, and Adam Levin
• The Defense Production Act of 1950 (DPA) provides the President with the
authority to mobilize the domestic economy in service of the national defense,
broadly defined, which may include emergency management and disaster
recovery purposes. The DPA generally does not provide direct financial
assistance to SLTTs. However, it does allow the federal government to intervene
in the civilian economy to facilitate the provision, movement, and expanded
production of critical goods, materials, and services. During an extreme heat
event, DPA authorities could be used to procure and distribute supplies, or
provide resources to SLTTs to mitigate adverse effects.
Congressional Considerations
As the United States faces another projected season of extreme heat, Congress may consider the
following policy issues, among others.
Clarifying the Federal Role in Managing Extreme Heat
“Who is in charge of extreme heat?” is an ongoing question asked by emergency managers,
government officials, and members of the public.138 At least one recent study found that SLTT
public health entities like hospitals, health departments, and emergency services often end up
bearing the greatest responsibility for managing extreme heat response, planning, and costs.139
However, most jurisdictions do not designate a branch or official specifically responsible for

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

extreme heat response and/or mitigation.140 No federal agency claims responsibility for managing
emergency preparedness and response to extreme heat, raising additional concern.141
According to a range of experts and advocates, this “governance gap” has confused response
efforts and increased risk to workers, students, and other members of the public.142 It may also
inhibit the design of new authorities, funds, or insurance policies to assist governments at all
levels in covering the costs associated with heatwaves.
Since at least the early 1980s, experts and some Members of Congress have called on the federal
government to assume a larger role in a national response program for extreme heat and
establishing standards to determine a heat-related death.143 The establishment of NIHHIS in 2015
cohered federal existing efforts to provide information on risks associated with extreme heat. Yet
some experts raise concern that the federal government’s role in extreme heat response remains
unclear.144 For example, in fall 2023, the Federation of American Scientists (FAS) launched a call
for policy ideas to support a coordinated federal role in managing risks from extreme heat; FAS
held a summit among participants in March 2024 that has put forth new ideas for Congress to
monitor.145
Amid these debates, Congress may clarify what—if any—role the federal government should
take in extreme heat events. Should Congress affirm the federal government’s role in assisting
with extreme heat response, it may seek to clearly delineate a lead agency, key authorities, and
relevant funding mechanisms to avoid confusion seen around federal interventions in other public
health incidents, including the COVID-19 pandemic.146 However, some may argue that scarce
federal resources may become overburdened should the federal government assume a larger role
in such incidents—both due to the expected frequency of extreme heat events, and because
federal emergency response funding and personnel have been strained in recent years.147

For more information on federal assistance that has been provided for past episodes of extreme
heat, see Appendix B.
Adapting Existing Grant Programs to Extreme Heat Response
None of the federal assistance programs summarized in this report were specifically designed to
provide assistance for the impacts of extreme heat events.148 Further, previous uses of the above
programs for extreme heat response that CRS could identify were relatively limited in scope and
frequency. For example, while the LIHEAP statute authorizes “emergency contingency funds” for
distribution to one or more grantees in cases of “natural disaster and other emergency”149 (a
natural disaster includes “a weather event (relating to hot or cold weather)”),150 Congress has not
appropriated emergency contingency funds since FY2011, and FY2007 was the last year in which
funds were awarded to grantees (two states and tribes within those states) due to extreme heat.151
For more information on federal assistance that has been provided for past episodes of extreme
heat, see Appendix B.
Despite the relatively limited known use of federal assistance for extreme heat response, some
agencies appear to be directing existing programs more deliberately towards extreme heat
emergencies by modifying policies, guidance documents, and grantee communications. For
example, HUD released new guidance on the use of CDBG funds to assist during the Pacific
Northwest 2021 episode of extreme heat,152 and in late 2022 FEMA released guidance on how
communities could use existing mitigation funds to support resilience to extreme heat.153 In fall
2023, FEMA also launched a series of events publicizing potential mitigation resources for
extreme heat.154
These adaptations may enhance nonfederal capacity to respond to extreme heat. However, some
raise concerns that such actions divert resources away from the efforts for which these programs
were originally designed, or introduce undesirable competition for scarce funds.155 Some grant
programs may also be difficult for certain jurisdictions to access. For example, some local health

148 Given the lack of readily available data, it is unclear how the other listed programs have been consistently utilized
for extreme heat, despite their potential relevance. The absence of reporting and tracking requirements for some grants
hinder efforts to measure federal assistance historically provided for extreme heat response. For example, Community
Service Block Grant funds may fund subgrants to local organizations that do not require consistent reporting. For more

jurisdictions may lack the workforce capacity and subject matter expertise to contend with an
increased focus on heat emergencies amid other public health threats.156
Congress may consider monitoring agency modifications to existing funding sources to
communicate such changes to nonfederal partners and potential grant recipients. Congress may
also consider appropriating new funds to support the expanded scope of existing programs.
Alternatively, Congress could discourage agencies from adapting existing grant programs given
the risk of resource competition, and instead address extreme heat through other means.
Stafford Act Declarations for Extreme Heat
Presidents have denied past requests for Stafford Act declarations for extreme heat (for further
discussion see “Department of Homeland Security—FEMA”). These denials align with historical
trends: Presidents generally have issued Stafford Act declarations for sudden-onset hazards that
caused structural damage (e.g., hurricanes and tornadoes).157 This pattern may be attributable to
regulatory authorities that primarily rely upon the costs of structural damages as thresholds for
particular forms of federal assistance,158 the applicability of assistance available under the
Stafford Act for extreme heat, and existing interpretations of events that qualify as major disasters
under the Stafford Act.159
Some recent declarations suggest these trends—and understandings of the scope of the Stafford
Act—are changing. For example, prior to 2020, the Stafford Act was rarely invoked for public
health incidents.160 In such instances, the President declared an emergency—a broadly defined
event eligible for less assistance than a major disaster.161 In 2020, President Donald J. Trump
issued 59 major disaster declarations for the COVID-19 pandemic, the first major disasters
declared for a public health incident under current law.162 Since then, President Biden has issued
Stafford Act emergency declarations for an influx of sargassum in the U.S. Virgin Islands,163 the
Mississippi water crisis,164 an intrusion of seawater into freshwater sources in Louisiana,165 and
lead and copper contamination of the water supply of the U.S. Virgin Islands,166 all which are
fairly novel declarations for ongoing incidents without extraordinary physical damage.

158 See CRS Insight IN11534, Will FEMA Recommend Public Assistance Following a Disaster? Proposed Rulemaking,
by Erica A. Lee. While FEMA’s Individual Assistance program does not use set damage “thresholds” that must be met
in order for assistance to become available, consideration is given to the uninsured and underinsured home and personal
property losses resulting from the incident that are eligible for certain forms of assistance, as well as certain measures
of the affected state or territory’s capacity and resources to manage the incident. See CRS Report R46014, FEMA

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

The relevance of Stafford Act declaration for extreme heat has also attracted new attention. In
September 2023, FEMA Administrator Deanne Criswell affirmed that extreme heat was eligible
for Stafford Act assistance if an incident exceeded state and local capacity to respond and
recover.167 If Congress determines that the Stafford Act should be more clearly available for
extreme heat response, Congress could consider directing FEMA to give greater consideration to
casualties and other nonstructural losses when evaluating the need for Stafford Act declarations
and associated financial assistance for emergency response for hazards like extreme heat.168
Congress could also consider legislation introduced in the 118th Congress amending the definition
of a major disaster to explicitly include extreme heat events.169
Members of Congress concerned about how Stafford Act declarations for extreme heat could
strain FEMA’s existing response and recovery capacity and funding may consider other ways that
FEMA does and could reduce risks related to extreme heat.170
For example, FEMA could further incorporate extreme heat into hazard mitigation assistance and
requirements. In 2022, FEMA clarified that mitigation assistance available outside of a specific
incident or declaration could support heat-related preparedness and adaptation measures (e.g.,
development of heat emergency communications and response plans,171 installation of cool roofs
and shade structures)172 into existing requirements for governments applying for federal
assistance.173 This may encourage more nonfederal governments to prepare for and reduce future
costs and casualties associated with extreme heat. FEMA could take additional actions, for
example, requiring jurisdictions to incorporate heat health action plans into mitigation plans
required to be in place to access certain forms of Public Assistance and Hazard Mitigation
Assistance.174 Such a requirement could reorient attention towards the threat of extreme heat,
which most state hazard mitigation plans do not sufficiently consider.175 Similarly, Congress
could encourage FEMA to expand the forms of reasonable hazard mitigation measures it will

fund through the Individuals and Households Program to include assistance for eligible extreme
heat measures (e.g., installing an air-conditioner in a disaster survivor’s home).176
Designing Federal Assistance for Emergency Response to Extreme Heat
An increase in heat-related deaths is among the first dangers to human health discussed in the
U.S. Global Change Research Program’s Fifth National Climate Assessment.177 Further, experts
project that extreme heat events are likely to become more frequent, severe, and longer in
duration, placing particular stress on populations living in urban areas.178
Extreme heat may also compound or increase risks of other hazards. For example, federal
officials have recently warned that extreme heat episodes may strain certain power supply
systems in the United States, leading to rolling blackouts or power losses.179 This could
precipitate additional threats to human health and safety as people lose access to air-conditioning
and critical electricity-dependent medical equipment.180 Some experts have underscored the
particular vulnerability of low-income residents who experience extreme heat as they may forgo
air-conditioning to avoid high energy costs, or experience electricity disconnection due to
nonpayment of electricity costs.181 These compound hazards are not easily incorporated into
federal incident management procedures designed to evaluate and manage discrete incidents.182
For these reasons, Congress may consider revising existing statutory authorities providing federal
assistance available for emergency response, or creating new authorities, to explicitly provide
assistance for emergency response to extreme heat. Under current law and practice, requests for
federal assistance for extreme heat response may compete with demands for emergency
assistance or preparedness for hazards that more commonly receive federal attention and
assistance; for example, hurricanes, terrorist attacks, or infectious disease incidents.
Congress could clarify the applicability of existing authorities to ensure the availability of federal
assistance for extreme heat. It could, for example, incorporate specific language directing or

176 Currently FEMA’s IHP Home Repair Assistance includes eligible hazard mitigation measures to withstand high
winds and prevent water infiltration and flood damage, as well as mitigation for individuals affected by wildfire
damage. In June 2021, FEMA announced initial mitigation measures that are eligible for Home Repair Assistance, and
in July 2022, FEMA announced additional eligible wildfire mitigation measures (FEMA, “Hazard Mitigation Under the

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

incentivizing recipients to undertake measures for heat response, preparedness, and mitigation
into appropriations for HHS’s PHEP Cooperative Agreement. Alternatively, Congress could
provide new financial or operational assistance programs specifically designed to enhance the
ability of jurisdictions to respond to the threat of extreme heat and reduce the future risks to
public health and safety to avoid creating competition for resources in existing programs. For
example, Congress could authorize and appropriate an emergency fund deployed to provide
advance assistance for extreme heat incidents that meet a pre-determined severity or duration,
thereby eliminating the delays of assistance programs which depend upon damage assessments
and/or reimbursements. Alternatively, Congress could authorize a program providing direct
federal assistance (e.g., personnel, expertise) for nonfederal jurisdictions launching their own
extreme heat operations.
Congress may also weigh the potential fiscal demands of such new or clarified authorities to
provide assistance for extreme heat and the potential burdens placed on federal, state, and local
emergency response offices to execute such authorities. Some may prefer to retain existing
flexibilities so as to allow nonfederal governments and public health authorities to determine the
best use of existing grant funds.
Communicating and Increasing Public Understanding of Health Risks of
Extreme Heat
State and local governments’ preparedness and response to extreme heat has sometimes garnered
criticism, with some researchers finding that governments do not adequately plan, neglect plans
and previous experiences, and thus begin “from ‘scratch’” in each new incident.183 This may
result, in part, from officials’ lack of understanding of the human experience of and vulnerability
to heat,184 which many individuals lack as well.185 Without such understanding, individuals and
communities may fail to recognize and respond to the dangers of extreme heat until it is too late.
As a result, some stakeholders have called upon the federal government to enhance risk
awareness and “heat literacy” at the local level:
[E]ducation is a really important role that the Federal Government can play in supporting
resilience efforts at the local scale for heat or other hazards…. [A]gencies like NOAA, like
the CDC and others can be very helpful in building heat literacy at the local level,
understanding the design vocabulary, the specifications. What is the difference between air
temperature and surface temperature, for example? These are critical concepts that our
local leaders need to have ... to help our residents.186
Heat.gov aims to address this need by providing a central repository of tools and information on
heat health risks to vulnerable communities intended, in part, for emergency managers. Congress

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

may evaluate how affected communities use the resource, particularly during the 2024 summer
months.
Congress may consider whether, and how, federal agencies and experts could play additional
roles in ensuring members of the public are aware of their risk—for example, by establishing a
national information campaign about the risks of extreme heat, prioritizing heat-related projects
in competitive grant programs, providing training to nonfederal government officials, or
supporting mutual aid or other heat information-sharing mechanisms across local governments.
The federal government could, separately, establish a measure of extreme heat around which
emergency managers and governments may construct their own authorities or guidelines to
protect public health, or which could help individuals understand their own risk. Some recent
research suggests that extreme heat is a rising concern among many state and local jurisdictions
in the United States,187 perhaps precluding a more robust need for risk communication from the
federal government.
Insurance for Extreme Heat
Despite the costs they may incur due to extreme heat, state and local governments have few
relevant insurance policy options.188 For this reason, governments (and public and nonprofit
hospitals and other medical services) generally pay related costs on their own (e.g., uninsured
patient care, energy costs, structural damages, mortuary operations), particularly given the lack of
federal assistance generally available for extreme heat. The resulting costs could become
unmanageable in the face of more intense and frequent hot days.189
Insuring a government against extreme heat presents several difficulties, according to insurers
and policymakers.190 First, there is not always a clear party responsible for the effects of extreme
heat, as noted above.191 Second, exactly what is being insured in a government’s policy for
extreme heat is not as clearly defined as it may be for other hazards. While a city insures real
property against the risk of damages from hurricanes or tornados, how could it insure the welfare
and health of local residents against extreme heat?192
Amid these difficulties, insurers are exploring different ways for governments to protect
themselves against certain risks associated with extreme heat. For example, some have considered

of heat action plans, see Ladd Keith et al., “Planning for Extreme Heat: A Review,” Journal of Extreme Events, vol. 6,

covering activities covered in a jurisdiction’s heat action plan (e.g., the cost of operating cooling
center during a heatwave).193 Others have conceived of policies wherein payments are triggered
during certain well-defined heatwaves, without the need to make a claim (known as parametric
insurance).194 Some insurance experts have called upon industry stakeholders to model policies
that could insure governments against certain losses incurred during extreme heat for costs
including emergency communications, transportation, cooling centers, and increased electricity
use; other proposals include pooling risks among cities in a given state, or issuing supplemental
coverage to public hospitals for the operational costs of extreme heat response.195
Congress may monitor developments in private insurance that may help nonfederal governments
manage the risks and costs of extreme heat. New policies could help Congress to understand how
the private sector may help jurisdictions cope during widespread or persistent heat emergencies.
At the same time, Congress may note that nonfederal governments are particularly likely to be
bearing the costs of extreme heat incidents on their own.196 This could make future extreme heat
events particularly burdensome for certain communities that may be coping with high casualties
and high costs without many resources to draw upon.
Conclusion
The 118th Congress has experienced the hottest year in U.S. history. As the United States enters
the summer months of 2024, Congress may consider how American communities will cope, how
the federal government may be called upon to assist, and whether and how Congress seeks such
help to be provided.

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

Appendix A. Department of Energy Assistance for
Energy Access Relevant to Extreme Heat Events
The following programs offer assistance for energy access that could promote community or
individual resilience to extreme heat.
Energy Efficiency and Conservation Block Grant Program
DOE’s Energy Efficiency and Conservation Block Grant (EECBG) program provides funding to
local governments, states, territories, and tribes to reduce energy use and carbon emissions and to
increase energy efficiency at the local and regional level.197 An eligible entity may use the
funding to carry out 14 types of activities including strategy development, energy efficiency
building retrofits, and clean energy deployment, among others. In addition to the identified
activities, the Secretary of Energy in consultation with the Administrator of the EPA, the
Secretary of Transportation, and the Secretary of Housing and Urban Development also may
approve any other appropriate activity. Eligibility requirements include payment of prevailing
wage rates, submission of a strategic plan, and sharing of information.
Weatherization Assistance Program
DOE’s Weatherization Assistance Program (WAP) provides funding to states, tribes, and
territories to enable low-income families to permanently reduce their energy consumption by
making their households more energy efficient. DOE program guidelines specify that a variety of
energy efficiency measures are eligible for support under the program. The measures include
insulation, space-heating equipment, energy-efficient windows, water heaters, and efficient air-
conditioners. The Energy Act of 2020 (Division Z, P.L. 116-260) amended the program, included
a clarification that renewable energy technologies and other advanced technologies are considered
to be weatherization materials, and authorized DOE to account for the non-energy benefits of
weatherization improvements—such as improvements to health and safety—when determining
appropriate standards and procedures for WAP.198
State Energy Program
DOE’s State Energy Program (SEP) provides funding and technical assistance to states, the
District of Columbia, and territories to promote the efficient use of energy and reduce the rate of
growth of energy demand through the development and implementation of specific state energy
programs. In order to be eligible for financial assistance through the SEP, grantees are required to
develop energy plans with mandatory and optional features. Grantees may use the funds to
support a range of activities including energy efficiency upgrades and retrofits of public facilities,
piloting of innovative energy projects, installation of renewable energy systems, and
implementation of energy security, resiliency, and emergency preparedness plans.199

Home Energy Rebates Programs
DOE’s Home Energy Performance-Based, Whole-House Rebates, also known as a HOMES
(Home Owner Managing Energy Savings), authorizes state energy offices (SEOs) to provide
rebates for energy efficiency upgrades that improve the overall energy performance of a single-
family home (SFH) or multi-family building (MFB). The types of eligible upgrades are not
specified but could include efficient windows, doors, and insulation materials.200 DOE’s High-
Efficiency Electric Home Rebate (HEEHR) Program authorizes SEOs to provide point-of-sale
rebates to eligible entities for qualified electrification projects. This can include rebates for
purchase and installation of space heating/cooling equipment of up to $8,000 for households that
satisfy income means-testing requirements. Both programs were authorized and funded through
P.L. 117-169, commonly known as the Inflation Reduction Act of 2022 (IRA).

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

Appendix B. Selected Past Federal Assistance for
Emergency Response to Extreme Heat
The federal government has never responded to an extreme heat event through the Stafford Act.
However, federal assistance for emergency response has been provided through other federal
relief programs for certain heatwaves; selected examples are provided below. This list may not be
comprehensive.
1980 Extreme Heat in Multiple States
In 1980, drought conditions exacerbated the effects of an episode of extreme heat in parts of the
Central and Southern Plains region of the United States.201 NOAA scientists estimated that
extreme heat directly caused up to 1,300 deaths and $16 billion in economic losses in the most
severe episode of extreme heat in the United States since 1954, according to the agency.202
Governor Joseph Teasdale of Missouri requested a major disaster declaration under the Stafford
Act for extreme heat early in the summer of 1980, and submitted a second request for extreme
heat and drought later that year.203 President Jimmy Carter denied both requests; however, he
directed then-FEMA Administrator John Macy “to coordinate the Federal response to this
situation,” in conjunction with state governments of affected areas.204
Congress passed P.L. 96-321, authorizing the transfer of funds to support assistance for the
incident.205 The President directed the then-Community Services Administration (CSA) to
provide approximately $6.7 million to six states to assist low-income individuals and senior
populations at risk, for measures including transportation to cooling centers, acquisition of air-
conditioning units, payment of utility bills, and other services.206 Additionally, the President
directed both CSA and HHS to reprogram up to $21 million of existing Energy Crisis Assistance
Program funds to assist affected areas. Several affected hospitals lacking air-conditioning
requested emergency assistance from the U.S. Air Force and Army reserve to secure portable
units, and the mayor of St. Louis testified that the National Guard flew in air-conditioners from
New York.207

Emergency Response to Extreme Heat: Federal Financial Assistance and Considerations

1995 Extreme Heat in Illinois and Midwest
In July 1995, several states in the Midwest experienced extreme heat; the CDC and certain
medical scholars estimated that the incident caused at least 700 excess deaths in Chicago.208
President William J. Clinton denied Governor Edgar’s request for a major disaster declaration for
the 1995 Chicago heat wave. However, he announced the provision of $100 million through the
Low Income Home Energy Assistance Program (LIHEAP) to assist with low-income residents
electricity bills in 19 states, including tribes within the states. 209 Awards were based on
temperatures during the July heat wave and the amount of low-income housing in the state, with
Illinois receiving the most funding ($15.7 million).210 The Department of Health and Human
Services also provided technical assistance to local governments in Illinois coping with the
effects of the heat wave in Cook County and Chicago, according to FEMA’s Administrator James
Lee Witt.211
1998 Extreme Heat in South and Southwestern United States
Abnormally hot temperatures affected Texas and several states in the southern and southwestern
United States during the summer months of 1998.212 President Clinton released $150 million in
emergency LIHEAP funds to the 11 southern and southwestern states that were hit hardest by the
heat wave, including tribes within those states,213 explaining that “those who cannot afford air-
conditioning are at real peril of further health risks as the heat wave goes on.”214
1999 Extreme Heat in Multiple States
In July 1999, several weeks of extreme heat affected multiple states across the country and
ultimately resulted in several hundred heat-related deaths.215 Officials in Chicago, one of the
hardest-hit localities, estimated that the heat wave cost the city approximately $100,000 a day,
and media reported that the Governor of Illinois requested emergency assistance to assist low-
income individuals and elderly residents with electricity costs.216 On July 12, 1999, President
Clinton released $100 million in emergency funds through LIHEAP for 17 states (and tribes
