Association of mortality and combined oxidative capacity of ozone and nitrogen dioxide
Improved global air quality health index reveals ozone and nitrogen dioxide as main drivers of air-pollution-related acute mortality
Priority climate and health modelling needs
Climate and health modelling is necessary for improving understanding of the current and future distribution and timing of climate-related health risks. However, underinvestment in this area has limited the understanding required to inform policies that enable multisectoral interventions to safeguard health. We synthesised insights from a survey of 65 global climate and health modelling experts and 36 participants in a hybrid meeting to identify …
Associations of ambient exposure to benzene, toluene, ethylbenzene, and xylene with daily mortality
The overlooked health impacts of extreme rainfall exposure in 30 East Asian cities
Total economic costs of climate change at different discount rates for market and non-market values
What will be the aggregated cost of climate change in achieving the Paris Agreement, including mitigation, adaptation, and residual impacts? Several studies estimated the aggregated cost but did not always consider the critical issues. Some do not address non-market values such as biodiversity and human health, and most do not address differentiating discount rates. In this study, we estimate the aggregated cost of climate change using an integra…

METHODS: In this modelling study, we collected time-series data on mortality and ambient temperatures from 750 locations in 43 countries and five meta-predictors at a grid size of 0·5° × 0·5° across the globe. A three-stage analysis strategy…
Hot weather and heat extremes
Reducing the health effects of hot weather and heat extremes
The burden of heat-related mortality attributable to recent human-induced climate change
Climate change affects human health; however, there have been no large-scale, systematic efforts to quantify the heat-related human health impacts that have already occurred due to climate change. Here, we use empirical data from 732 locations in 43 countries to estimate the mortality burdens associated with the additional heat exposure that has resulted from recent human-induced warming, during the period 1991-2018. Across all study countries, w…
Energy transitions, air quality and health
The way we produce and use energy is transforming. Policy in this area intersects decisions that affect climate change, air quality, and the economy. The exponential increase in use of fossil fuel and nuclear energy has now essentially replaced human and animal energy (McKinney 2019 Curr. Pollut. Rep. 5 394–406; Solomon and Krishna 2011 Energy Policy 39 7422–31). These transitions have contributed to notable gains, such as improvements in mortali…

However, evidence on this direct impact at a global scale is limited, mainly due to issues in modelling and projecting complex and highly heterogeneous epidemiological relationships across different populations and climates. METHODS: We collected observed daily time series of mean temperature and mortality counts for all causes or n…
Exploring the effects of high temperature on mortality in four cities in the Philippines using various heat wave definitions in different mortality subgroups
BACKGROUND: Sustained high temperatures, specifically heat waves (HW), increase the risk of dying, especially among risk populations, which are highly vulnerable to its additional effect. In developing countries, there are only a few studies which focused on the magnitude of the risks attributed to HWs. OBJECTIVES: This study explored the HW effects using 15 HW definitions through the combination of duration (> 2, > 4, and > 7 consecutive days) a…
Cost of preventing workplace heat-related illness through worker breaks and the benefit of climate-change mitigation
The exposure of workers to hot environments is expected to increase as a result of climate change. In order to prevent heat-related illness, it is recommended that workers take breaks during working hours. However, this would lead to reductions in worktime and labor productivity. In this study, we estimate the economic cost of heat-related illness prevention through worker breaks associated with climate change under a wide range of climatic and s…
How Does Ambient Air Temperature Affect Diabetes Mortality in Tropical Cities
Diabetes is well-known as one of the many chronic diseases that affect different age groups. Currently, most studies that evaluated the effects of temperature on diabetes mortality focused on temperate and subtropical settings, but no study has been conducted to assess the relationship in a tropical setting. We conducted the first multi-city study carried out in tropical cities, which evaluated the temperature-diabetes relationship. We collected …

OBJECTIVES: Our goal was to investigate the relationship between temperature and mortality in Hue, a subtropical city in Viet Nam. DESIGN: We collected daily mortality data from the Vietnamese A6 mortality reporting system for 6,214 decease…
Effect modification in the temperature extremes by mortality subgroups among the tropical cities of the Philippines
BACKGROUND: Temperature-mortality relationships have been extensively probed with varying temperature range but with relatively similar patterns and in some instances are being modified by specific mortality groups such as causes of mortality, sex, and age. OBJECTIVE: This study aimed to determine the risk attributions in the extreme temperatures and also identified the risks associated with the various mortality subgroups. DESIGN: We used the 20…
The Role of Influenza in the Delay between Low Temperature and Ischemic Heart Disease
Many studies have found that cardiovascular deaths mostly occur within a few days of exposure to heat, whereas cold-related deaths can occur up to 30 days after exposure. We investigated whether influenza infection could explain the delayed cold effects on ischemic heart diseases (IHD) as they can trigger IHD. We hypothesized two pathways between cold exposure and IHD: a direct pathway and an indirect pathway through influenza infection. We creat…

Issues in health risk assessment of current and future heat extremes
BACKGROUND: In assessing health risks relating to current and future heat extremes, it is important to include developing countries, because these countries are considered to be vulnerable to the impact of climate change due to inadequate public health infrastructure, nutritional status and so forth. However, it is usually difficult to obtain relevant information from these countries, also because of insufficient public health infrastructure. OBJ…
Global Variation in the Effects of Ambient Temperature on Mortality
BACKGROUND: Studies have examined the effects of temperature on mortality in a single city, country, or region. However, less evidence is available on the variation in the associations between temperature and mortality in multiple countries, analyzed simultaneously. METHODS: We obtained daily data on temperature and mortality in 306 communities from 12 countries/regions (Australia, Brazil, Thailand, China, Taiwan, Korea, Japan, Italy, Spain, Unit…
Flood risk and climate change
A holistic perspective on changing rainfall-driven flood risk is provided for the late 20th and early 21st centuries. Economic losses from floods have greatly increased, principally driven by the expanding exposure of assets at risk. It has not been possible to attribute rain-generated peak streamflow trends to anthropogenic climate change over the past several decades. Projected increases in the frequency and intensity of heavy rainfall, based o…
Global-scale projection and its sensitivity analysis of the health burden attributable to childhood undernutrition under the latest scenario framework for climate change research
This study assessed the health burden attributable to childhood underweight through 2050 focusing on disability-adjusted life years (DALYs), by considering the latest scenarios for climate change studies (representative concentration pathways and shared socioeconomic pathways (SSPs)) and conducting sensitivity analysis. A regression model for estimating DALYs attributable to childhood underweight (DAtU) was developed using the relationship betwee…
Mortality risk attributable to high and low ambient temperature
BACKGROUND: Although studies have provided estimates of premature deaths attributable to either heat or cold in selected countries, none has so far offered a systematic assessment across the whole temperature range in populations exposed to different climates. We aimed to quantify the total mortality burden attributable to non-optimum ambient temperature, and the relative contributions from heat and cold and from moderate and extreme temperatures…
Temporal Variation in Heat–Mortality Associations
BACKGROUND: Recent investigations have reported a decline in the heat-related mortality risk during the last decades. However, these studies are frequently based on modeling approaches that do not fully characterize the complex temperature-mortality relationship, and are limited to single cities or countries. OBJECTIVES: We assessed the temporal variation in heat-mortality associations in a multi-country data set using flexible modelling techniqu…
