TL;DR: The data show independent associations between short-term exposure to PM10 and PM2.5 and daily all-cause, cardiovascular, and respiratory mortality in more than 600 cities across the globe, and reinforce the evidence of a link between mortality and PM concentration established in regional and local studies.

TL;DR: In this article, the authors show that climate change can directly affect human health by varying exposure to non-optimal outdoor temperature, however, evidence on this direct impact at a global scale is limited.

TL;DR: A comprehensive characterisation of future heatwave-related excess mortality across various regions and under alternative scenarios of greenhouse gas emissions, different assumptions of adaptation, and different scenarios of population change is provided to help decision makers in planning adaptation and mitigation strategies for climate change.

TL;DR: Several city indicators modify the effect of heat, with a higher mortality impact associated with increases in population density, fine particles, gross domestic product (GDP) and Gini index (a measure of income inequality), whereas higher levels of green spaces were linked with a decreased effect ofHeat.
