“…Given constraints in computational resources and consistent with prior analyses, four months were selected in each modeled year, 2018 (baseline) and 2030 (future), to represent critical air pollution seasons: January (representing winter, December–February), May (representing summer/pre-monsoon, March–May), July (representing monsoon/rainy season, June–September), and October (representing post-monsoon/autumn, October–November). These seasonal period categorizations are consistent with those in prior published work by the Indian Institute of Tropical Meteorology, Indian Institute of Public Health-Gandhinagar, and the India Meteorological Department (Parthasarathy et al 1987 , Sanjay et al 2020 , Beig et al 2021 , Wei et al 2021 ). Based on that seasonal representation, we calculated a manually-weighted daily city average PM 2.5 level to characterize the annual concentration across the city.…”

Climate change-driven temperature increases worsen air quality in places where coal combustion powers electricity for air conditioning. Climate solutions that substitute clean and renewable energy in place of polluting coal and promote adaptation to warming through reflective cool roofs can reduce cooling energy demand in buildings, lower power sector carbon emissions, and improve air quality and health. We investigate the air quality and health co-benefits of climate solutions in Ahmedabad, India—a city with air pollution levels above national health-based standards--through an interdisciplinary modeling approach. Using a 2018 baseline, we quantify changes in fine particulate matter (PM2.5) pollution and all-cause mortality in 2030 from increasing renewable energy use (mitigation) and expanding Ahmedabad’s cool roofs heat resilience program to cover 20% of available building roof area (adaptation). We apply local demographic and health data and compare a 2030 mitigation and adaptation (M&A) scenario to a 2030 business-as-usual (BAU) scenario (without climate change response actions), each relative to 2018 pollution levels. We estimate that the 2030 BAU scenario results in an increase of PM2.5 pollution of 4.13 µg/m3 compared to a 0.11 µg/m3 decline under the 2030 M&A scenario. Reduced PM2.5 pollution under 2030 M&A results in 1,216-1,414 fewer premature all-cause deaths annually compared to 2030 BAU. Achievement of Indian Clean Air Programme, national standards, or World Health Organization annual PM2.5 targets in 2030 results in up to 6,510, 9,047, or 17,369 fewer annual deaths, respectively, relative to 2030 BAU. This comprehensive modeling method is adaptable to estimate local air quality and health co-benefits in other settings by integrating climate, energy, cooling, land cover, air pollution, and health data. Our findings demonstrate that city-level climate change response policies can achieve substantial air quality and health co-benefits. Such work can inform public discourse on the near-term health benefits of mitigation and adaptation.

As a place for the maintenance of high-speed trains, the current ventilation system in the train depot cannot meet comfort requirements according to the feedback from the inspection department. The poor thermal environment could seriously affect the physical health and work efficiency of staff. This study provides some basic data and design methods for improving the thermal environment in high-speed railway depots. Field studies were conducted in five different high-speed railway depots in hot summer regions of China, including the form and the operation of the ventilation system, the thermal and humid environment and the characteristics of the heat sources. According to the survey results, the maximum temperature in the depot can reach 41.2°C in summer. There is a clear vertical temperature stratification in the afternoon of the depot, and the maximum temperature difference between three working platforms can reach more than 4°C. The cooling effect of ventilation systems in depot was investigated and compared. The recommended ventilation mode is natural ventilation system + bottom mechanical air supply system + ceiling fan system, and it is recommended to combine the west window louvers with external sun shading to achieve the best cooling effect in high-speed railway depot.

Climate change and health in informal settlements: a narrative review of the health impacts of extreme weather events

In this paper, we present a narrative review of primary research on the health impacts of extreme weather events in urban informal settlements published between 1990 and June 2021. We include 54 studies and examine the health impacts of extreme weather events and how these were determined. We find that these events impact health directly by causing mortality, injury and disease and through indirect pathways by impacting livelihoods, access to healthcare, coping strategies and adaptive capacity. Drawing on the social determinants of health framework to frame our analysis, we find that health impacts are determined by multiple intersecting factors, relating to individual circumstances, material conditions, health status, and political and socio-economic context. Consequently, vulnerability varies between and within informal settlements. Overall, we show that responding to and minimising these health impacts requires an intersectional approach to understand and address these contextual root causes of vulnerability.
