Alan Barreca in Time: How Rising Temperatures Due to Climate Change are Shortening Pregnancies

According to a new study published in Nature Climate Change, rising temperatures may have a direct impact on human gestational time, increasing the risk of early delivery.  To study this effect, Alan Barreca, an associate professor at UCLA’s Institute of Environmental Sustainability, and economist Jessamyn Schaller of Claremont McKenna College, analyzed daily temperature and county-by-county birth rates across the U.S. in a two-decade window from 1969 to 1988.
