New evidence reveals that prenatal exposure to extreme weather events, including Superstorm Sandy and combined extreme heat, leads to alterations in fetal brain structures associated with emotional regulation. The findings stem from neuroimaging studies of children exposed in utero, showing enlarged basal ganglia and other region changes potentially impacting long-term emotional health. This research highlights an underappreciated impact of climate change on neurodevelopmental outcomes, underscoring the need for further investigation into early-life environmental stressors.
