Too Hot to Learn: Climate Shocks in Pregnancy and Early Life Shape Education

Overview

The Conversation summarizes evidence that climate shocks experienced during pregnancy and early childhood are linked to health and education outcomes for children. Across 254 studies, including 90 statistical analyses core to the review, exposure to floods, droughts and unusually high temperatures is associated with lower birthweight, poorer childhood development, later school entry, reduced enrollment and fewer years of education. Impacts are often more severe in low and middle income countries where families have fewer resources to cope with food loss, income shocks and limited access to healthcare. The article also discusses possible supports such as social protection programs, cash transfers and targeted services for pregnant women and young children. The author highlights that protection can cushion some of the long term effects of early climate shocks.

Introduction

Climate change is increasingly shaping opportunities for children before they even enter a classroom. The piece discusses how exposure to extreme weather during pregnancy and early childhood—floods, droughts and heat—can influence birth outcomes and long term educational trajectories. It draws on a wider review of 254 studies, with 90 core statistical studies, to identify patterns in health, learning and education access that emerge across different settings and income levels.

Evidence Across Contexts

In Ecuador, for example, researchers looked at mothers who experienced severe flooding during pregnancy and found that every additional month of flood exposure was associated with lower household income and food consumption in the following year. Exposed children tended to have low birthweight and anaemia, and performed worse on tests of thinking and language development. In rural Burkina Faso, prenatal exposure to unusually low rainfall correlated with lower scores on cognitive tests and a tendency to start school later, with decreased enrollment and higher likelihood of child labor.

A broader study linking climate conditions during pregnancy and early childhood to later educational attainment found that in South East Asia, temperatures well above local norms predicted about 1.5 fewer years of schooling on average. These findings underscore how timing and severity of climate shocks, combined with family circumstances, shape outcomes.

Unequal Risks

The evidence comes from a wider review that included 254 studies, with 90 statistical analyses forming a core. A consistent pattern emerged: climate shocks during pregnancy and early childhood can affect health, learning, and eventual years of schooling. Importantly, the consequences are not evenly distributed. Families with savings, insurance or robust public services have more resilience and faster recovery, while those without such buffers experience more severe cuts to nutrition, healthcare access and schooling when shocks hit.

Another key insight is the distribution of risk—children in countries that have contributed relatively little to greenhouse gas emissions often bear the greatest burden, highlighting climate justice dimensions of the issue.

Policy Responses: Social Protection and Cash Transfers

The review examined interventions and found that among six studies assessing cash transfers during droughts, floods or cyclones, four reported positive effects on education. The impact varied by age, the size of payments, and the shock's severity. Mexico's Progresa cash-transfer program offers a concrete example: children born in adverse rainfall years showed larger educational losses, but those whose families received cash transfers experienced smaller losses, illustrating how cash support can cushion adverse effects even when the shock persists.

Cash transfers cannot eliminate the disaster or replace broader climate action, but they can stabilize household food security, healthcare access and schooling during income shocks. With international development budgets under pressure, the article notes that protecting support for pregnant women and young children remains essential to prevent long term losses in education and life chances.

Implications and Takeaways

Climate shocks during the earliest stages of life can influence learning and education long after a flood recedes, reinforcing the case for targeted social protection and maternal-child health support as part of climate adaptation strategies. The Conversation argues for prioritizing policies that protect pregnant women and young children to promote better educational outcomes and longer term opportunities, even as broader emissions reductions and adaptation efforts continue.
