Climate Disparities Begin Before Entering the Classroom: Disasters During Pregnancy May Influence Future Educational Attainment

Climate Disparities Begin Before Entering the Classroom: Disasters During Pregnancy May Influence Future Educational Attainment

The Heat Takes Away More Than Just the Class in Front of You

Hot winds blow in through the windows, and even with the fan on, the air in the classroom remains heavy. Children at their desks wipe away sweat as they try to listen to the teacher. Given the recurring heatwaves around the world in recent years, it's only natural to question, "Can learning continue in dangerous heat?"

However, the issues linking climate change and education extend beyond hot classrooms and school closures.

The impact may begin even before a child first steps into school, or even while still in the mother's womb. Research has accumulated showing that floods, droughts, and extreme heat experienced during pregnancy or early childhood can affect birth health and development, influencing school entry age, learning outcomes, and the number of years a child can continue attending school.

Climate change is not just an environmental issue. It is also a matter of health, poverty, education, and intergenerational inequality.


Climate Shocks During Fetal Development Lead to Later Developmental Impacts

Pregnancy is a period when the fetus's body and brain are rapidly forming. If food and income are lost during this time, preventing pregnant women from getting adequate nutrition or necessary medical care, the effects may linger after birth.

Disasters do not directly cause "educational loss" to the fetus. The issue is that disasters change living conditions, weakening the foundation of health and development as a result.

If drought leads to poor crop yields, agricultural income drops, and the quantity and quality of family meals decline. If floods cut off roads, accessing prenatal care and medical services during childbirth becomes difficult. Pregnant women may also have to work longer to make up for living expenses.

Even after birth, if household income declines or food shortages persist, infants may not receive adequate nutrition or care. These overlapping pathways can cause climate shocks to cascade into children's growth, cognitive abilities, language development, and school life.


Long-term Effects Confirmed by Floods in Ecuador

One example demonstrating this chain is research conducted in Ecuador.

In Ecuador, mothers who experienced large-scale floods associated with El Niño during pregnancy and their children were surveyed. The analysis confirmed that the more months they were exposed to floods, the lower the household income and food consumption the following year.

Children who experienced floods during the fetal period were more likely to have low birth weight and anemia, and tended to be shorter for their age. Furthermore, they scored lower on some cognitive and language development tests.

The important point here is that the impact of the flood does not end when the water recedes.

Damage to homes and farmland, reduced income, and poor meals affect the health of pregnant women and fetal development, further connecting to children's growth and readiness for learning. Even if a disaster is a temporary event, its aftereffects can last for a long time.


Drought May Increase "Working Children"

Research targeting rural areas in Burkina Faso, West Africa, also examined the relationship between insufficient rainfall during pregnancy and the future of children.

Children who experienced less rainfall than usual before birth tended to score lower on tests related to thinking and learning abilities. They were also reported to enter school later, have lower enrollment rates, and were more likely to engage in labor.

In regions highly dependent on agriculture, less rain is not just a change in weather. It affects harvests, meals, household budgets, medical expenses, school supplies, and the ability to send children to school.

If household finances worsen, even if tuition is free, families may not be able to afford uniforms, textbooks, or transportation. Moreover, if children are needed to help with chores, farming, or supporting the household income, continuing school attendance becomes difficult.

In other words, climate shocks change not only children's abilities but also the very "environment where they can go to school."


Do Children Who Experience High Temperatures Have Shorter Education Years?

A study using data from 29 tropical countries analyzed the relationship between climate conditions from pregnancy to early childhood and later educational attainment.

Children exposed to temperatures significantly above the regional average tended to have shorter final educational years. In Southeast Asia, it was estimated that children who experienced extreme heat had about 1.5 fewer years of schooling than those who experienced average temperatures.

Of course, education is not mechanically determined by temperature alone. Many factors, such as household income, regional healthcare, school quality, disaster support, gender, and dependence on agriculture, are involved.

Nonetheless, a difference of about 1.5 years is not small. Shortened education years can also affect future income, employment options, and access to health information.


Common Patterns Emerging from 254 Studies

A comprehensive review introduced in the original article examined 254 studies related to climate change and education, with 90 statistical studies used for core analysis.

Despite differences in phenomena and regions, such as floods, droughts, cyclones, and high temperatures, a common pattern emerged: climate shocks during pregnancy or early childhood can affect children's health, development, learning, and schooling duration.

However, the research results do not imply a deterministic view that experiencing a disaster once inevitably leads to learning failure.

The magnitude of the impact varies depending on the timing of the damage, the intensity of the disaster, the family's economic situation, and the available medical and public support. Even with the same scale of flooding, families with savings, insurance, and access to clinics and shelters have significantly different resilience compared to those struggling with daily food expenses.

What the research reveals is not that climate shocks harm all children equally, but the risk of expanding existing disparities.


The Issue is "Climate Inequality," Not Just "Climate Change"

Wealthy families might move to air-conditioned places on hot days, repair homes after flooding, and find alternative hospitals if transportation is halted. Even if children take a break from school, they might catch up with tutors or online materials.

On the other hand, in low-income families, a single crop failure can lead to reduced meal frequency, and interrupted medical visits due to flooding can affect maternal and child health. Children might have to work to support the household, leading to school dropouts.

Moreover, many low- and middle-income countries, which are more vulnerable to severe impacts, have contributed relatively little to historical greenhouse gas emissions. Children in regions that have emitted the least are paying a significant price in terms of education and future opportunities.

When climate change measures are discussed solely in terms of emissions and energy, this inequality becomes less visible. Climate policy needs to integrate perspectives on maternal and child health, nutritional support, education, and poverty alleviation.


Three Reactions Seen on Social Media

The specified article is newly published, and a sufficient number of posts directly related to the article were not confirmed in public searches. Therefore, representative reactions from public posts on the same theme of "climate change and children's future" are organized here.

 

The first is the strong anxiety of parents concerned about their children's future.

On the overseas forum Reddit, a first-time mother questioned whether there is hope for her daughter's future in the face of advancing climate change. The post received not only pessimistic opinions but also reactions blaming the act of having children, leaving the poster bewildered.

This reaction reflects the impact of the climate crisis on the psychology of the parenting generation, rather than an evaluation of research results. It is perceived not as a distant future environmental issue but as a pressing concern about "what kind of world one's child will live in."

The second voice emphasizes understanding risks accurately and taking action, rather than concluding a catastrophic future.

In the same discussion, a mother claiming to research agriculture and climate change replied, urging calmness by stating that "not all children are immediately at risk of survival." However, she also pointed out that regions with limited technology, resources, and political influence face greater dangers, and progress in emission reductions and adaptation strategies is insufficient.

Excessive pessimism leads to a sense of helplessness. However, ignoring disparities to provide reassurance is also inappropriate. The important thing is to see who is at risk and to what extent, rather than relying on an average world view.

The third appeal is to place children's perspectives at the center of climate policy.

UNICEF posted on X, stating that climate change is fundamentally altering children's breathing, thinking, and dreams. This expression succinctly indicates that the impact of climate change includes not only injuries and evacuations during disasters but also health, education, and hope for the future.

What these social media reactions have in common is the perception of the issue as something related to the choices of currently living children and parents, rather than an abstract future prediction. However, individual posts are not opinion polls and do not represent the views of society as a whole. They should be read as examples of problem awareness that have appeared in the public space.


Cash Transfers Can Mitigate Educational Losses

A child's future after experiencing climate shocks is not necessarily fixed. Research indicates that with appropriate support, recovery is possible.

One countermeasure is cash transfers through social security systems. This mechanism provides funds to households whose income has decreased due to disasters or poor harvests, allowing them to maintain food, medical care, and schooling. Some systems make school attendance and health check-ups conditions for receiving benefits.

Of the six studies dealing with cash transfers during droughts, floods, and cyclones, four confirmed positive educational effects. However, the effects vary depending on the child's age, the amount of the transfer, and the scale of the disaster.

In a study in rural Mexico, children who experienced unfavorable rainfall conditions before and after birth completed fewer grades and were less likely to continue learning after secondary education. However, children from families receiving benefits from the social assistance program "Progresa" experienced relatively smaller educational losses.

Cash transfers do not stop floods or rebuild damaged schools. They are not a substitute for greenhouse gas emission reductions. Nonetheless, they can serve as a "breakwater" to maintain meals, medical care, and schooling when household finances deteriorate rapidly, preventing children from leaving school.


Air Conditioning in Classrooms Alone Won't Solve the Problem

To address heatwaves, improving school insulation, shading, ventilation, air conditioning, and water supply is essential. Classes should not continue under dangerous heat.

However, merely renovating school facilities is not enough to fully prevent impacts that begin during pregnancy or early childhood.

What is needed is to consider nutritional support for pregnant women, access to medical care before and after childbirth, infant health check-ups, school meals, cash transfers during disasters, agricultural insurance, and securing transportation and communication as a continuous support system.

Especially after climate disasters, it is necessary to quickly identify changes such as whether pregnant women are receiving medical care, whether infants' meal quantities are not decreasing, and whether children have started working, in addition to visible building damage.

Delays in starting support can turn short-term living difficulties into long-term educational disparities.


Do Not Pit Mitigation Against Adaptation

In responding to climate change, "mitigation" to reduce greenhouse gases and "adaptation" to prepare for changes already occurring are sometimes discussed as opposing strategies.

However, from the perspective of children's education, focusing on only one is insufficient.

If emission reductions do not progress, the risks of extreme heat and heavy rain will continue to expand. On the other hand, even if emissions are reduced immediately, the impacts of already ongoing climate change cannot be completely avoided. To protect women currently pregnant and children growing up now, investments in social security, healthcare, and disaster-resilient schools must be pursued simultaneously.

Investment in climate adaptation in the education sector is not merely a cost for school building repairs. It is also an investment in human capital that protects individuals from birth to future employment.


The Question is Whether We Can Return to a "Post-Disaster Society"

Once the floodwaters recede, roads reopen, and schools resume, society may seem to have returned to normal. However, the time for pregnant women who reduced meals, infants who missed check-ups, and children who started working to support the household cannot be easily reversed.

The true damage of climate disasters cannot be measured solely by the number of deaths or collapsed buildings. It may manifest over a long period in terms of when children entered school, how many years they continued, and what jobs they could choose.

Therefore, the criteria for recovery must also change.

It's not just about restoring buildings but also confirming whether children have returned to the path of health and learning. Instead of separating pregnancy, birth, early childhood, and school age into different policy areas, they should be connected as the growth of a single child. This perspective is key to preventing temporary shocks from climate change from turning into lifelong disparities.

What the heat threatens to take away is not just today's focus in class. It is the learning time and future choices of the next generation, including children not yet born.
