Study Links Climate Change to Altered Brain Development in Children Exposed to Extreme Weather In Utero
June 14, 2025
A recent study reveals that climate change impacts begin in the womb, significantly affecting children's brain development due to extreme weather events experienced during pregnancy.
Yoko Nomura, a researcher from Queens College, urges society to develop strategies to protect pregnant individuals from climate impacts, which have been associated with risks like preterm births.
Research led by Donato DeIngeniis found that children exposed to Superstorm Sandy in utero exhibited altered brain structures, particularly in the basal ganglia, a region crucial for motor skills and emotional regulation.
For seven children exposed to both Superstorm Sandy and extreme heat during pregnancy, the brain differences were even more pronounced, suggesting complex neurological implications.
The study's research team plans to conduct a larger study with approximately 80 participants to further explore these findings and raise public awareness of the issue.
Previous studies have indicated that stress from non-climate-related events can also affect fetal brain development, but this research uniquely focuses on the effects of natural disasters.
The findings suggest that climate-related stressors faced by pregnant individuals could negatively influence their offspring's neurodevelopment, highlighting the urgent need for better education on climate risks for expectant parents.
While the study evaluated a small sample of 34 children, experts like Burcin Ikiz emphasize its importance in understanding the cumulative effects of climate stressors on health.
Among the children studied, those whose parents were pregnant during Sandy showed a 6% increase in the size of the basal ganglia, indicating potential negative behavioral outcomes linked to conditions such as depression and autism.
Superstorm Sandy, which struck in October 2012, caused widespread destruction in New York and New Jersey, displacing over 23,000 people and resulting in numerous fatalities and extensive damages.
These findings underscore the vulnerability of contemporary coastal ecosystems to large-scale climatic changes, drawing parallels between ancient climate events and current environmental challenges.
Overall, this research highlights the critical intersection of climate change and health, particularly regarding its impact on the developing brains of children.
