Climate Change arid Children's Health and Well-Being in the United States

Summary for Parents and Caregivers

Climate change is already affecting the health and well-being of
Americans. Children are uniquely vulnerable in part because they
are growing and developing. Children - especially younger
children - also have less control over their environment, less
knowledge about health effects from climate change, and are less
able to remove themselves from harm. Climate impacts can have
lifelong consequences stemming from effects on learning ability,
physical development, chronic disease, or other complications.

For more details, please see
the report, appendices, and
data linked below.

v>EPA

This factsheet summarizes findings from EPA's report Climate Change and Children's Health and
Weil-Being in the United States which quantifies future health risks to children for a sub-set of key
impacts, in addition to reviewing a broader set of pathways in which children are affected by climate
stressors. The analyses presented in this report are part of the EPA's Climate Change Impacts and
Risk Analysis (CIRA) project, a framework quantifying and monetizing the impacts of climate change
in the U.S. Some of the findings most relevant to parents and caregivers are summarized in the pages
that follow by climate stressor. The pages also identify the ways parents and caregivers can reduce
risks to children.

f| Extreme Heat

lOI Extreme heat, including sustained high temperatures and heat waves, can have a
variety of effects on children's physical and psychosocial health and cognitive
capabilities. Effects may include overheating, dehydration, and death, as well as premature birth or
low birth weight, clinical psychological impacts, and an inability to concentrate or learn.

WHAT DID THIS
REPORT FIND?

Heat experienced
during the school year
affects learning in
children. This report
projects a reduction in
annual academic
achievement per child
of 4% under a moderate
level of warming (2°C).

These losses can affect

potential losses across cohorts of graduating students
reaching billions of dollars annually, even under more
moderate warming scenarios. Installing air conditioning
(A/C) in schools is generally less costly, although this
action only partially mitigates these effects. Black,
Hispanic or Latino, and low-income students report the
lowest rates of current A/C in schools, and therefore are
likely to experience these impacts disproportionately.

WHAT EMERGING ISSUES
SHOULD PARENTS AND
CAREGIVERS BE AWARE OF?

The number of emergency
department visits among
children is expected to increase
between May and September
each year as summer
temperatures continue to rise,
up to tens of thousands of
additional visits annually.

HOW CAN CAREGIVERS HELP REDUCE RISKS TO CHILDREN?

•	Talk with children about limiting time outdoors in hot weather.

•	Educate yourselves and children on proper hydration in all
temperatures, how to recognize the early warning signs of
dehydration and overheating, including fatigue,
lightheadedness or dizziness, excessive sweating or lack of
sweating, and the risks associated with exposure to high heat.
Emphasize that dehydration can occur easily even in what
seems like lower temperatures.

•	Empower children to know how to advocate for safe practices
in outdoor activities, and destigmatize safety, especially in
sports.

Air Quality

Most health effects associated with poor air quality stem from climate-induced
changes in weather conditions that impact concentrations of particulate matter (PM)
and ozone, including wildfires and ground-level dust in the Southwest. Exposure to poor air quality
can result in the development and exacerbations of asthma, difficulty learning, and susceptibility to
bronchitis, cancers, and chronic obstructive pulmonary disease (COPD) in adulthood. Preterm birth,
low birth weight, and birth defects are associated with maternal exposures to poor air quality.

WHAT DID THIS REPORT FIND?

Rates of childhood respiratory diseases, such as asthma,
have been increasing steadily over the past decades, in
part due to changes in air quality and more children
being exposed to higher levels of air pollutants. New
asthma diagnoses across the U.S. are projected to
increase 4% due to climate change-induced effects on
air quality at 2°C of global warming. This rate rises to
11% under a higher level of warming. Low-income and
Black, Indigenous, people of color (BIPOC) children are
more likely to experience new asthma diagnoses
associated with climate-related exposure to PM2.5,

WHAT EMERGING ISSUES
SHOULD PARENTS AND
CAREGIVERS BE AWARE OF?

Emergency department (ED) visits
and hospital admissions from
respiratory conditions also are
expected to increase, because of
these effects, as are school days lost.
Further, the analysis projects an
increase in premature deaths among
newborns due to poor air quality
impacts on maternal health.

Wildfire smoke is comprised of
numerous other air pollutants that
pose significant human health
impacts, including adverse birth
outcomes. New research documents
the association between wildfire
smoke exposure and risk of preterm
birth, suggesting a dramatic potential
increase in these outcomes as
wildfire activity continues to increase.

HOW CAN CAREGIVERS HELP REDUCE RISKS TO CHILDREN?

•	Avoid letting children play outside on days with the poorest air quality (e.g.,
orange- or red-colored air quality alerts). You can check the Air Quality Index
forecast for your area.

•	Reduce exposure to wildfire smoke and ambient dust by closing windows and
vents in homes and vehicles and using high-efficiency furnace or HVAC filters
and/or portable air cleaners during smoke emergencies or poor air quality days.

•	Learn more on patient health related to ozone, particulate pollution, wildfire
smoke, and safeguarding indoor air qualit\ during wildfires.

Changing Seasons

Increasing temperatures and changing rainfall patterns are extending the growing
season, resulting in longer and more intense pollen and allergy seasons. Seasonal
allergic rhinitis is a major contributor in the U.S. to the development of respiratory conditions,
including asthma.

WHAT DID THIS REPORT FIND?

Due to climate-driven increases in some pollen types,
rates of annual asthma-related ED visits are projected
to increase by 17- 30%, under more moderate to higher
levels of warming, 2°C to 4°C, respectively. Less severe
outcomes, like visits to healthcare facilities for allergies
and prescriptions filled for allergy medications for
children, may increase by the tens to hundreds of
thousands annually at higher levels of warming (4°C or
greater). Limited English-speaking or BIP0C children,
and children without health insurance are more likely to
experience these impacts stemming from oak pollen
exposure specifically.

WHAT EMERGING ISSUES
SHOULD PARENTS AND
CAREGIVERS BE AWARE OF?

Overall, new evidence suggests that
lengthening warm seasons are
expected to result in more time
spent on outdoor recreation,
especially boating and water sports.
On the other hand,
the number of
trips associated
with some
recreation
types, like
winter

recreation and
cold-water
fishing, are
projected to decrease under climate
change. These changes are likely to
have both positive and negative
effects, in terms of physical health,
mental well-being, and injury risks.

HOW CAN CAREGIVERS HELP REDUCE RISKS TO CHILDREN?

•	Talk with your child's doctor about potential risk factors associated
with allergen exposure.

•	Talk with your child's doctor about how to recognize symptoms of
seasonal allergies, allergy testing, and appropriate medication.
Maintain awareness of your area's air quality, and limit your child's
time outdoors on days with high pollution levels, including high
pollen concentrations (check local Air Quality Index forecast).

Flooding

Coastal and inland flooding can result in exposures to waterborne diseases, housing
uncertainty, and psychological trauma. The frequency of flooding events due to
storm surge and sea level rise will continue to worsen as the climate changes, affecting homes of
children living in coastal zones.



WHAT DID THIS REPORT FIND?

If no additional adaptation actions are taken, more than
1 million children are estimated to experience
temporary home displacement or complete home loss
from coastal flooding, at even moderate levels of global
mean sea level rise. Under greater levels of sea level rise,
the report anticipates that more than 2 million children
will be affected due to increases in coastal flooding.
Children in overburdened households will experience
these impacts disproportionately. Well-timed adaptation
measures, including building sea walls, could avoid or
delay many of these impacts, but are themselves costly
to implement and maintain.

WHAT EMERGING ISSUES
SHOULD PARENTS AND
CAREGIVERS BE AWARE OF?

Inland flooding, also known as
riverine flooding, could increase in
the future due to climate change,
leading to home damage and loss.

HOW CAN CAREGIVERS HELP REDUCE RISKS TO CHILDREN?

•	Work with your family to identify evacuation routes and
strategies to follow at times of flooding and severe weather.

•	If your family has experienced home damage or loss, consider
seeking psychological treatment for your children. Learn more
about caring for children after disasters.

•	Children and pregnant people should not take part in flood
cleanup work. Be aware of the risks of mold and Information on
how to cleanup mold.

Infectious Diseases

The range of vector-borne diseases from mosquitoes and ticks, and the duration of
favorable weather conditions for the vectors, are expected to increase in a changing
climate, Lyme disease is one of the most common and best-known tick-borne diseases in the U.S. If
left untreated, or if treatment is delayed, children may develop a range of severe health effects,
including juvenile arthritis and Lyme carditis (inflammation in the heart).

WHAT DID THIS REPORT FIND?

This report projects a
significant increase in
new cases of Lyme
disease (Lyme
borreliosis) among
children in the
Eastern U.S. even at
lower levels of global
warming (2°C), with
an expected 31%
increase in cases. At
higher levels of global
warming (4°C), the overall number of new cases
increase 272% above present levels. States in the
northernmost areas of the Northeast and Midwest
regions are expected to see most of new cases among
children. Some research demonstrates that Lyme
disease may be underdiagnosed, misdiagnosed, and
undertreated among some overburdened
populations, particularly BIPOC children, increasing
the likelihood of more severe outcomes in these
communities.

WHAT EMERGING ISSUES
SHOULD PARENTS AND
CAREGIVERS BE AWARE OF?

West Nile Virus (WNV), a mosquito-
borne virus, is likely to see a change in
new cases as temperatures increase,
including among children. While this
disease often does not cause severe
illness in children, it can have serious
health effects in children with pre-
existing conditions. Additionally,
changes in case counts could be
indicative of increasing risks of other
mosquito-borne illnesses, such as
Zika, that can have severe health
implications for children.

HOW CAN CAREGIVERS HELP REDUCE RISKS TO CHILDREN?

•	Teach your children about appropriate measures for avoiding
exposures to ticks and mosquitos, including wearing long-sleeves
and long pants, or proper application and use of insect repellants.

•	Be aware of and teach older children about how to identify early
symptoms of illness, including the Lyme disease "bullseye" rash
and other characteristics.

•	Remain current on tick bite treatment protocols and localized
disease rates.
