(Phys.org)—A trio of researchers affiliated with multiple institutions in the U.S. has found evidence that suggests children exposed to high temperatures for even short periods can experience lower earnings as adults. In their paper published in Proceedings of the National Academy of Sciences, Adam Isen, Maya Rossin-Slater and Reed Walker describe comparing temperatures in the U.S. decades ago with earnings data for adults today to find patterns of changes in earnings due to heat exposure.
