Exhaustion

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.

The 2022 report of the Lancet Countdown is published as the world confronts profound and concurrent systemic shocks. Countries and health systems continue to contend with the health, social, and economic impacts of the COVID-19 pandemic. At the same time, Russia's invasion of Ukraine and persistent fossil fuel overdependence have pushed the world into global energy and cost-of-living crises. As these crises unfold, climate change escalates unabated. Its worsening impacts are increasingly affecting the foundations of human health and well-being, exacerbating the vulnerability of the world's populations to concurrent health threats.

Urban areas continue to be the center of action for many countries due to their contribution to economic development. Many urban areas, through the urbanization process, have become vulnerable to climate risk, thereby making risk mitigation and adaptation essential components in urban planning. The study assessed the impacts of IPCC Assessment Reports (ARs) on academic research on risk mitigation and adaptation concerns in urban areas. The study systematically reviewed literature through searches of the Web of Science and Scopus databases; 852 papers were retrieved and 370 were deemed eligible.

The report “Interactive Effects of High Temperature and Air Pollution in Europe” was prepared as a milestone by researchers in the EU Project EXHAUSTION*. This report summarises the evidence on the interactive effects of high temperature and various air pollutants on heart- and lung-related deaths and diseases (cardiopulmonary (CPD) mortality and morbidity) across Europe. The study was conducted at the city, small-area (e.g. suburban areas or municipalities), and individual level. The findings highlight the urgency in improving air quality across Europe, and alert stakeholders and policymakers that climate change adaptation measures need to be also taken into account to protect vulnerable subgroups and thereby increase European resilience towards climate change.
