Exhaustion

Chronic exposure to air pollution (ambient PM2.5) is the largest environmental health risk in Europe. We used a chemical transport model and recent exposure response functions to simulate ambient PM2.5, contribution from fires and related health impacts over Europe from 1990 to 2019. Our estimation indicates that the excess death burden from exposure to ambient PM2.5 declined across Europe at a rate of 10,000 deaths per year. Excess deaths from fires increased by more than 100% during the same period.

Climate change could lead to high economic burden for individuals (i.e. low income and high prices). While economic conditions are important determinants of climate change vulnerability, environmental epidemiological studies focus primarily on the direct impact of temperature on morbidity and mortality without accounting for climate-induced impacts on the economy. More integrated approaches are needed to provide comprehensive assessments of climate-induced direct and indirect impacts on health.

Background: The epidemiological evidence on the interaction between heat and ambient air pollution on mortality is still inconsistent.

This article investigates the interaction between heat and ambient air pollution on daily mortality in a large dataset of 620 cities from 36 countries.

Background: Heat effects on respiratory mortality are known, mostly from time-series studies of city-wide data. A limited number of studies have been conducted at the national level or covering non-urban areas. Effect modification by area-level factors has not been extensively investigated. Our study assessed the heat effects on respiratory mortality at a small administrative area level in Norway, Germany, and England and Wales, in the warm period (May-September) within 1996-2018. Also, we examined possible effect modification by several area-level characteristics in the framework of the EU-Horizon2020 EXHAUSTION project.

Background: Short-term associations between heat and cardiovascular disease (CVD) mortality have been examined mostly in large cities. However, different vulnerability and exposure levels may contribute to spatial heterogeneity. This study assessed heat effects on CVD mortality and potential vulnerability factors using data from three European countries, including urban and rural settings.

Climate change can substantially affect temperature-related mortality and morbidity, especially under high greenhouse gas emission pathways. Achieving the Paris Agreement goals require not only drastic reductions in fossil fuel-based emissions but also land-use and land-cover changes (LULCC), such as reforestation and afforestation. LULCC has been mainly analysed in the context of land-based mitigation and food security. However, growing scientific evidence shows that LULCC can also substantially alter climate through biogeophysical effects.

Ambient air pollution is a major global public health risk factor. There is now broad consensus that exposure to air pollution causes an array of adverse health effects based on evidence from a large scientific literature that has grown exponentially since the mid-1990s. Air pollution damages most organ systems and is linked to many debilitating diseases, such as asthma, cardiovascular diseases, chronic obstructive pulmonary disease, pneumonia, stroke, diabetes, lung cancer, and dementia.

• Heat effect modification by air pollution on cardiovascular and respiratory mortality was investigated across 482 cities.
• Heat effect was seen to be significantly modified by air pollutants PM10, PM2.5, O3, and NO2.
• This study is the most extensive research to date investigating the heat effect modification on cardiovascular and respiratory mortality.
• This is the first-ever study to deeply investigate effect modifications by air pollutants such as PM2.5 and NO2.

Heat and cold are established environmental risk factors for human health. However, mapping the related health burden is a difficult task due to the complexity of the associations and the differences in vulnerability and demographic distributions. In this study, we did a comprehensive mortality impact assessment due to heat and cold in European urban areas, considering geographical differences and age-specific risks.

• Present and future global PM2.5 and O3-related premature mortality is estimated.
• The present day global premature mortality is estimated to be 5.4 million.
• Bias correction increases global PM2.5-related premature mortality to 7.7 million.
• Emission reductions alone decreases premature mortality by up to 57% in 2050.
• Aging population increases premature mortality by up to a factor of 2.

Feedbacks between air pollutants and meteorology play a crucial role in the direction of the response of future climate and air pollution. These feedbacks are important to understand and quantify the potential impact of adaptation and mitigation policies setup for protecting the population against air pollution and heat stress.

This study provides a comprehensive assessment of excess mortality related to non-optimal outdoor temperature, with several risk indicators reported by age and multiple geographical levels. The analysis provides detailed risk maps that are useful for designing effective public health and climate policies at both local and national levels.

High air temperatures and heat extremes are associated with a large burden of cardiovascular disease, especially among the elderly and people with pre-existing health conditions. Under the influence of global warming as well as population growth and ageing, the heat-related impact on health is expected to increase in the upcoming decades. Therefore, the implementation of heat-health action plans is urgently needed to protect the public.

In this Review, we aim to provide an overview of the consequences of climate change on cardiovascular health, which result from direct exposure pathways, such as shifts in ambient temperature, air pollution, forest fires, desert (dust and sand) storms and extreme weather events. We also describe the populations that are most susceptible to the health effects caused by climate change and propose potential mitigation strategies, with an emphasis on collaboration at the scientific, governmental and policy levels.

Globally, a substantial mortality burden was associated with temperature variability, showing geographical heterogeneity and a slightly increasing temporal trend. Our findings could assist in raising public awareness and improving the understanding of the health impacts of temperature variability.

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.

We investigate the novel use of summer temperature-mortality associations established by these models for monitoring heat-related deaths in regions in England in near real time. For four summers in the period 2011–2020, we find that coupling these associations with observed daily mean temperatures results in England-wide heatwave mortality estimates that are consistent with the excess deaths estimated by UK Health Security Agency. However, our results for 2013, 2018 and 2020 highlight that the lagged effects of heat and characteristics of individual summers contribute to disagreement between the two methods.

The report “Effects of air Temperature on Cardiopulmonary Mortality and Morbidity in Europe” was prepared as a milestone of the EU Project EXHAUSTION. It summarizes the evidence on the effects of different levels and changes in ambient air temperature on cardiopulmonary (CPD) mortality and morbidity across Europe and puts a spotlight on the vulnerable and susceptible population. It can help stakeholders and policymakers to plan adaptation measures to protect the vulnerable and susceptible population and increase European resilience towards climate change and extreme weather events.
