Exhaustion

Climate change and air pollution and their subsequent impacts on health remain an issue of concern (1). While there are numerous air-quality legislations in Europe, recent studies have shown that health impacts of air pollution are still a concern in Europe due to climate change. Changes in temperature levels in the future could imply an increase in chemical reaction rates that influence production and loss rates of gaseous pollutants and hence affect local and regional pollution levels.

The association between ambient air temperature and mortality has not been assessed in Norway. This study aimed to quantify for seven Norwegian cities (Oslo, Bergen, Stavanger, Drammen, Fredrikstad, Trondheim and Tromsø) the non-accidental, cardiovascular and respiratory diseases mortality burden due to non-optimal ambient temperatures.

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.

Older adults are generally among the most vulnerable to heat and cold. While temperature-related health impacts are projected to increase with global warming, the influence of population ageing on these trends remains unclear. Our findings indicate that population ageing constitutes a crucial driver for future heat- and cold-related deaths, with increasing mortality burden for both heat and cold due to the ageing population.

Ground-level ozone—a product of reactions between other atmospheric pollutants—can trigger coughing and shortness of breath, worsen asthma, and cause damage to airways. Short-term exposure to ground-level ozone can lead to respiratory and cardiovascular disease and has been linked to higher rates of premature death. Climate change and changes in the atmospheric concentrations of ozone precursor pollutants are projected to increase ground-level ozone in many parts of the world.

Heat stress in cities is projected to increase due to climate change strongly. The high population density in cities and the urban heat island effect will exacerbate the associated health risks. However, impacts are still uncertain, which is among other factors due to the existence of multiple metrics for quantifying ambient heat and the typically rather coarse spatial resolution of climate models. Here we investigate projections of ambient heat for 36 major European cities based on a recently produced ensemble of regional climate model simulations for Europe (EURO-CORDEX) at 0.11° spatial resolution (∼ 12.5 km).

Exposure to cold spells is associated with mortality. However, little is known about the global mortality burden of cold spells.

Heat stress in cities is projected to strongly increase due to climate change. The associated health risks will be exacerbated by the high population density in cities and the urban heat island effect. However, impacts are still uncertain, which is among other factors due to the existence of multiple metrics for quantifying ambient heat and the typically rather coarse spatial resolution of climate models. Our results emphasise the value of high-resolution climate model simulations for analysing climate extremes at the city level. At the same time, they highlight that improving the predominantly rather simple representations of urban areas in climate models would make their simulations even more valuable for planning adaptation measures in cities.

Climate change can directly impact temperature-related excess deaths and might subsequently change the seasonal variation in mortality. In this study, we aimed to provide a systematic and comprehensive assessment of potential future changes in the seasonal variation, or seasonality, of mortality across different climate zones.

In our study, we examined the possible modification of the heat effects on total and cause-specific mortality by air pollution at municipality level in the Attica region, Greece, during the warm period of the years 2000 to 2016. Our results support the evidence of elevated heat effects on mortality at higher levels of PM10 and 8 h max O3. Under climate change, any policy lowering air pollution levels will yield significant public health benefits.

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.

As the climate warms, increasing heat-related health risks are expected, and can be exacerbated by the urban heat island (UHI) effect. UHIs can also offer protection against cold weather, but a clear quantification of their impacts on human health across diverse cities and seasons is still being explored. Here we provide a 500 m resolution assessment of mortality risks associated with UHIs for 85 European cities in 2015-2017. The findings urge strategies aimed at designing healthier cities to consider the seasonality of UHI impacts and to account for social costs, their controlling factors, and intra-urban variability.

We used a risk matrix approach to develop heat-related hazard, impact, and risk maps.  We used satellite-derived land surface temperatures (MODIS LSTs) to cope with the need for a fine horizontal resolution for the climate index. We have defined the impact index as emergency (paramedic) interventions for daytime and nighttime, from the period June-August 2012-2017 (SMURD – Emergency Situation Inspectorate Bucuresti-Ilfov) and June-August 2018 (Service of Ambulance Bucuresti-Ilfov).

BACKGROUND AND AIM: In this study, we aim to gauge the impact of temperature fluctuations on productivity loss in Norway by examining the relationship between past temperature and sick leave. METHOD: We conducted our analysis using a panel dataset in the year 2018 for individual-location-specific daily temperatures and sick leave records from a national registry in Norway based on the Cohort of Norway (CONOR). RESULTS: Our findings suggest that temperature fluctuations had significant impacts on health and productivity, and these effects varied depending on the season and personal characteristics.

There is limited evidence of temporal changes in the association between air temperature and the risk of cause-specific cardiovascular [CVD] and respiratory [RD] mortality. We analysed a total of 3,159,292 non-accidental, 1,063,198 CVD and 183,027 RD deaths. We found evidence of rising population susceptibility to both heat- and cold-related CVD and RD mortality risk from 1993 to 2016. Climate change mitigation and targeted adaptation strategies might help to reduce the number of temperature-related deaths in the future.

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.
