Global warming has caused one-third of high-temperature-related deaths

A new article in "Nature Climate Change" states that between 1991 and 2018, more than one-third of all high-temperature-related deaths can be attributed to human-induced global warming

This research is the largest of its kind and is led by the London School of Hygiene and Tropical Medicine (LSHTM) and the University of Bern in the Multi-Country and Multi-City Cooperative Research Network (MCC)

Overall, estimates indicate that 37% of all heat-related deaths in the recent summer can be attributed to global warming caused by human activities

Estimates also show the number of deaths caused by man-made climate change in specific cities; 136 new deaths per year are in Santiago, Chile (44.

The lead author of the study, Dr.

Global warming is affecting our health in many ways, from direct effects related to wildfires and extreme weather, to changes in the spread of vector-borne diseases, and so on

This new research uses "detection and attribution" research to identify and attribute observed phenomena to climate and weather changes, focusing on man-made global warming

Although on average more than one-third of high-temperature-related deaths are caused by human-induced climate change, the impact varies greatly from region to region

In the UK, 35% of high-temperature-related deaths can be attributed to man-made climate change.

Professor Antonio Gasparini of the London School of Tropical Medicine, the senior author of the study and the coordinator of the MCC network, said: "This is the largest detection and classification study of the current health risks of climate change.

The authors acknowledge the limitations of the study, including the inability to include locations in all regions of the world due to lack of empirical data—for example, most of Africa and South Asia
