“…At the same time, the exposure to cold days will substantially decrease. Because there is a negative relationship between in utero exposure to hot weather (especially in the second and third trimesters) and health at birth (Deschênes et al 2009;Sun et al 2019;Hajdu and Hajdu 2020b; Barreca and Schaller 2020;Chen et al 2020), the slight change in timing of conception could have a non-negligible impact. Further consequences are also possible, as temperature exposure during pregnancy influences adult outcomes too (Wilde et al 2017;Isen et al 2017;Fishman et al 2019;Hu and Li 2019).…”

In this paper, we examine the relationship between temperature and human conception rates and project the impacts of climate change by the mid-twenty-first century. Using complete administrative data on 6.8 million pregnancies between 1980 and 2015 in Hungary, we show that exposure to hot temperatures reduces the conception rate in the first few weeks following exposure, but a partial rebound is observed after that. We project that with absent adaptation, climate change will increase seasonal differences in conception rates and annual conception rates will decline. A change in the number of induced abortions and spontaneous fetal losses drives the decline in conception rates. The number of live births is unaffected. However, some newborns will experience a shift in the timing of conception that leads to changes in in utero temperature exposure and therefore might have further consequences.

“…Moreover, strong health indicators at birth have been linked to positive long‐term socioeconomic outcomes such as physical health in adulthood, educational achievements, and labor earnings (Almond & Mazumder, 2011; Baguet & Dumas, 2019; Behrman & Rosenzweig, 2004; Bharadwaj et al., 2018; Xie et al., 2017). Motivated by these findings, for the last decade economists have sought to understand the impact on birth outcomes of maternal exposure to a variety of external factors: violence and conflicts (Camacho, 2008; Koppensteiner & Manacorda, 2016; Mansour & Rees, 2012; Quintana‐Domeque & Ródenas‐Serrano, 2017), natural or environmental disasters (Carrillo et al., 2020; Currie & Rossin‐Slater, 2013; Menclova & Stillman, 2020; Simeonova, 2011; Torche, 2011), weather shocks (Andalón et al., 2016; Chen et al., 2020; Deschenes & Moretti, 2009), air pollution (Currie & Walker, 2011), water scarcity (Rocha & Soares, 2015), economic crisis (Bozzoli & Quintana‐Domeque, 2014) and fasting (Almond & Mazumder, 2011). All of these factors were found to have detrimental effects on newborn health as measured by weight, gestational length, or the presence of abnormal conditions at birth.…”

Mosquito‐borne disease and newborn health

While mosquito-borne diseases are currently most prevalent in mid-latitude countries, rising global temperatures are expanding their range. This paper investigates whether one such disease, dengue, harms newborns. Health at birth has been shown to impact economic outcomes throughout life. The empirical design exploits variation in lagged dengue rates in a town's closest neighbors and largest trading partner. The underlying source of exogeneity in this variation comes from two components: the uneven allocation, across municipalities, of funding to combat the mosquito vector and random weather patterns. Past disease rates in adjacent areas are used as instruments for the dengue rate in a newborn's municipality of residence. Using administrative individual data from birth records in Brazil, I find that a one standard deviation increase in the incidence of dengue in the third trimester of gestation reduces birth weight by 0.75 grams on average. The effect is more pronounced for baby girls and for children of more educated mothers. Moreover, there seems to exist a positive effect of dengue exposure during the early stages of gestation among children of mothers that do not receive scheduled prenatal care. The likely channel is that these women access pregnancy resources as a consequence of seeking medical treatment for dengue.

“…In the short-term, higher ambient temperatures are associated with immediate increases in mortality for populations (Medina-Ramon et al, 2006), although the strength of this relationship has declined over the 20 th century in the U.S. as electricity and air conditioning became more widespread (Barreca et al, 2016). Prior findings have also documented how ambient temperatures in utero and during the early developmental period of life are associated with increased risk of stillbirths, decreased birth weight, and shorter aggregate lifespan for birth cohorts (Catalano et al, 2008;Catalano et al, 2011;Chen et al, 2020;Strand et al, 2011). Research examining adjacent, nondemographic outcomes of ambient temperature during gestation and early life have similarly found laterlife associations in the domains of education, employment, and earnings (Barron et al, 2018;Isen et al, 2017).…”

The Intergenerational Consequences of Climate Change on Later Life Mortality: Evidence from Individual-Level U.S. Death Records

Global climate change can impact populations rapidly through the increased occurrence of natural disasters and climate extremes, but also through long-term, gradual changes that alter environmental conditions and impair biological processes. Here, I investigate whether ambient temperatures in utero and during the early years of life are associated with reductions in life expectancy. I combine monthly, state-level climatological data from the National Oceanic and Atmospheric Administration with high-resolution, individual-level mortality data from the CenSoc Project, which consists of cleaned and harmonized Social Security Administration death records from 1988-2005. Results indicate that exposure to higher ambient temperatures during gestation and the first four years of life are associated with increased mortality risk in later life for white men from low socioeconomic status backgrounds, but not other groups. It is likely that the effect of climate variability on later life mortality for non-white men is overshadowed by structural systems of racism that impact health stratification. Overall, the results emphasize how climate change has already begun to imprint itself onto demographic processes.
