- Comparison of weather station and climate reanalysis data for modelling temperature-related mortalityPublication . Mistry, Malcolm N.; Schneider, Rochelle; Masselot, Pierre; Royé, Dominic; Armstrong, Ben; Kyselý, Jan; Orru, Hans; Sera, Francesco; Tong, Shilu; Lavigne, Éric; Urban, Aleš; Madureira, Joana; García-León, David; Ibarreta, Dolores; Ciscar, Juan-Carlos; Feyen, Luc; de Schrijver, Evan; de Sousa Zanotti Stagliorio Coelho, Micheline; Pascal, Mathilde; Tobias, Aurelio; Alahmad, Barrak; Abrutzky, Rosana; Saldiva, Paulo Hilario Nascimento; Correa, Patricia Matus; Orteg, Nicolás Valdés; Kan, Haidong; Osorio, Samuel; Indermitte, Ene; Jaakkola, Jouni J.K.; Ryti, Niilo; Schneider, Alexandra; Huber, Veronika; Katsouyanni, Klea; Analitis, Antonis; Entezari, Alireza; Mayvaneh, Fatemeh; Michelozzi, Paola; de’Donato, Francesca; Hashizume, Masahiro; Kim, Yoonhee; Diaz, Magali Hurtado; De la Cruz Valencia, César; Overcenco, Ala; Houthuijs, Danny; Ameling, Caroline; Rao, Shilpa; Seposo, Xerxes; Nunes, Baltazar; Holobaca, Iulian-Horia; Kim, Ho; Lee, Whanhee; Íñiguez, Carmen; Forsberg, Bertil; Åström, Christofer; Ragettli, Martina S.; Guo, Yue-Liang Leon; Chen, Bing-Yu; Colistro, Valentina; Zanobetti, Antonella; Schwartz, Joel; Dang, Tran Ngoc; Van Dung, Do; Guo, Yuming; Vicedo-Cabrera, Ana M.; Gasparrini, AntonioEpidemiological analyses of health risks associated with non-optimal temperature are traditionally based on ground observations from weather stations that offer limited spatial and temporal coverage. Climate reanalysis represents an alternative option that provide complete spatio-temporal exposure coverage, and yet are to be systematically explored for their suitability in assessing temperature-related health risks at a global scale. Here we provide the first comprehensive analysis over multiple regions to assess the suitability of the most recent generation of reanalysis datasets for health impact assessments and evaluate their comparative performance against traditional station-based data. Our findings show that reanalysis temperature from the last ERA5 products generally compare well to station observations, with similar non-optimal temperature-related risk estimates. However, the analysis offers some indication of lower performance in tropical regions, with a likely underestimation of heat-related excess mortality. Reanalysis data represent a valid alternative source of exposure variables in epidemiological analyses of temperature-related risk.
- Impact of population aging on future temperature-related mortality at different global warming levelsPublication . Chen, Kai; de Schrijver, Evan; Sivaraj, Sidharth; Sera, Francesco; Scovronick, Noah; Jiang, Leiwen; Roye, Dominic; Lavigne, Eric; Kyselý, Jan; Urban, Aleš; Schneider, Alexandra; Huber, Veronika; Madureira, Joana; Mistry, Malcolm N; Cvijanovic, Ivana; MCC Collaborative Research Network; Gasparrini, Antonio; Vicedo-Cabrera, Ana MOlder adults are generally amongst the most vulnerable to heat and cold. While temperature-related health impacts are projected to increase with global warming, the influence of population aging on these trends remains unclear. Here we show that at 1.5 °C, 2 °C, and 3 °C of global warming, heat-related mortality in 800 locations across 50 countries/areas will increase by 0.5%, 1.0%, and 2.5%, respectively; among which 1 in 5 to 1 in 4 heat-related deaths can be attributed to population aging. Despite a projected decrease in cold-related mortality due to progressive warming alone, population aging will mostly counteract this trend, leading to a net increase in cold-related mortality by 0.1%-0.4% at 1.5-3 °C global warming. Our findings indicate that population aging constitutes a crucial driver for future heat- and cold-related deaths, with increasing mortality burden for both heat and cold due to the aging population.
