Jump to Main Text of Report

Summary

The National Oceanic and Atmospheric Administration (NOAA) reported that several areas of 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. 2645; H.R. 4733/ S. 2383; H.R. 4314; H.R. 3965; H.R. 2945/S. 1379; H.R. 662/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, 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 meteorologically 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 generally 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, especially 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 power outages in hospitals, nursing homes, and operating rooms have required emergency 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;
  • 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

For more information on federal assistance provided in past episodes of extreme heat, see Appendix B.

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

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

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

Department of Health and Human Services

Administration for Strategic Preparedness and Response (ASPR)

The Administration for Strategic Preparedness and Response (ASPR) administers a suite of programs that aim to bolster the ability of hospitals, health care facilities, and health care systems 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.

Public Health Emergency Preparedness (PHEP) Cooperative Agreement100

CRS Expert: Hassan Sheikh

  • The Public Health Emergency Preparedness (PHEP) Cooperative Agreement provides assistance to 62 state, local, and territorial public health departments101 to strengthen public health preparedness and response capacity. PHEP Cooperative Agreement recipients engage in activities that align with the Public Health Emergency Preparedness and Response Capabilities, which allow for an all-hazards approach to responding to public health emergencies and the public health consequences of traditional disasters.102 Recipients can use funds to prepare for and respond to extreme weather, including heat events.103

Climate-Ready States & Cities Initiative104

CRS Expert: Kavya Sekar

  • The Climate-Ready States & Cities Initiative funds grantees' efforts to identify local climate change effects, potential health effects, at-risk populations, and potential mitigating interventions. Funds may be used for climate-related health planning activities. Currently, the Initiative funds 11 jurisdictions, including state, county, and local governmental agencies.105 A separate but related Climate-Ready Tribes Program funds a similar grant for three American Indian and Alaska Native (AI/AN) tribes (administered by the National Indian Health Board and funded by CDC).106

Preventive Health and Health Services (PHHS) Block Grant107

CRS Expert: Kavya Sekar

  • The Preventive Health and Health Services (PHHS) Block Grant is a flexible block grant to 61 health jurisdictions that allows grantees to address the unique and emerging public health needs of their communities, which could include those related to extreme heat.108

Administration for Children and Families

Community Services Block Grant (CSBG)109

CRS Expert: Conor Boyle

  • The Community Services Block Grant (CSBG) provides flexible funding to states, territories, and tribes for distribution to local agencies to support community-based activities to reduce poverty.110 Funds may be used for emergency assistance, which may include cooling center operations.

Low Income Home Energy Assistance Program (LIHEAP)111

CRS Expert: Libby Perl

  • The Low Income Home Energy Assistance Program (LIHEAP) is a flexible block grant to states, tribes, and territories for operating home energy assistance programs for low-income households.112 Grantees113 may use funds to pay for heating and cooling costs, crisis assistance, weatherization assistance, and services to reduce the need for energy assistance. HHS has issued memoranda stating that grantees may use funds to establish and operate cooling centers and provide air-conditioning units to eligible households, among other activities to prevent heat stress.114 In addition, HHS has established a LIHEAP and Heat Stress Geographic Information System Dashboard, which includes historical temperature data, information on the effects of extreme heat on health, and ways in which LIHEAP can help.115 Several Presidents have used LIHEAP to deliver emergency assistance for extreme heat, as detailed in Appendix B.

Department of Housing and Urban Development

Community Development Block Grant Program (CDBG)116

CRS Expert: Joe Jaroscak

  • The Community Development Block Grant Program (CDBG) provides flexible federal funding to states and localities to support economic development, community development, and infrastructure.117 In some cases, CDBG grantees could target or reprogram funds to prepare for or respond to extreme heat events. In particular CDBG funds could support the development or rehabilitation of public facilities,118 or the provision of public services119 to meet specific 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 Agriculture

CRS Expert: Lisa Benson

  • USDA Rural Development may provide assistance for certain kinds of projects in qualifying rural areas.124 For example, USDA Community Facilities Programs (such as Community Facilities Direct Loans and Grants)125 assist with developing or improving essential public services and facilities; these funds might be used for efforts related to community emergency shelters and cooling centers.126 The USDA Disaster Resource Center also gives timely information on assistance to communities affected by severe weather events and other disasters and emergencies.127 (See Rural Development State Offices for contacts.128)

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: Appalachian Regional Commission (ARC);132 Delta Regional Authority (DRA);133 Denali Commission;134 Northern Border Regional Commission (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 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 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 emergencya 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.

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 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 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 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.

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).

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

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 within those states) experiencing extreme heat. He released an additional $55 million in August 1999 to nine other states and tribes.217

2000 Extreme Heat in Southern United States

A severe drought and prolonged heat wave affected south-central and southeastern states, which NOAA estimated contributed to 140 deaths nationwide.218 On July 25, 2000, President Clinton released $41.75 million in LIHEAP funds to nine states, most of which was directed to southern states experiencing extreme heat.219

2002 Extreme Heat

Following extreme summer heat, HHS released $100 million in LIHEAP contingency funds to 34 states based on the severity of extreme heat between June and August, as well as the number of households with incomes below 125% of the federal poverty level.220

2007 Extreme Heat

HHS released $50 million in LIHEAP funds to 12 states and tribes within those states that experienced hotter than average temperatures during the month of August.221

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.
