Extreme heat-related mortality avoided under Paris Agreement goals

In key European cities, stabilizing climate warming at 1.5 °C would decrease extreme heat-related mortality by 15–22% per summer compared with stabilization at 2 °C.

There remains a paucity of studies into how risks differ between a 1.5 °C and a 2 °C world1, and the question this policy aspiration2 poses to the scientific community is what are the impacts avoided by stabilizing climate at 1.5 °C instead of 2 °C? Research has started to emerge for global changes in some specific sectors to address this question, such as the crop and water sectors3, but very little has emerged for regional impacts, especially from the health sector.
