Alan Barreca Study in Yahoo! Lifestyle: Could Climate Change Be Linked to Premature Birth?
Researchers examined 56 million births from 1969 to 1988 and correlated that data to weather data in the areas where the births occurred. They found a spike in deliveries on days where the mercury topped 90 degrees Fahrenheit. “That rise, then fall, indicates a forward shift or an acceleration of deliveries and ultimately a loss of up to two weeks gestation for those births,” said study author Alan Barreca, an associate professor in environmental economics at the University of California, Los Angeles.
