BACKGROUND: Climate change is expected to have adverse health effects, but the association between extreme ambient temperatures and stillbirth is unclear. OBJECTIVES: We investigated acute and chronic associations between extreme ambient temperatures and stillbirth risk, and estimated the attributable risk associated with local temperature extremes in the United States. METHODS: We linked 223,375 singleton births ≥23 weeks of gestation (2002–2008) from 12 U.S. sites to local temperature. Chronic exposure to hot (>90th percentile), cold (
