“…A burgeoning literature has identified adverse short-term impacts of extreme temperatures on several population outcomes, including elderly mortality (Deschênes and Moretti, 2009;Deschênes and Greenstone, 2011), emergency department visits and hospitalizations (Green et al, 2010;White, 2017), and cognitive performance (Cho, 2017;Garg et al, 2018;Goodman et al, 2018;Graff Zivin, Hsiang, and Neidell, 2018). Further, two recent studies have shown that in utero heat exposure has lasting negative effects on long-term cognitive ability (Hu and Li, 2019) and adult earnings (Isen, Rossin-Slater, and Walker, 2017), highlighting the sensitivity of the prenatal period to extreme heat.…”
