During the research, the scientists were Between 2015 and 2018, the number of deaths from high temperature in 732 cities around the world was analyzed. The death rate and temperature change in each city were investigated, as well as the relationship between the death rate and temperature change in different cities, and the high temperature death curve of these cities was drawn through a computer model.
The results found that, in general, countries with higher temperatures have a higher proportion of deaths, and the number of deaths from high temperatures will increase exponentially as the temperature rises. On average, 37% of deaths from high temperatures are caused by man-made climate warming.
Researchers said that in 732 cities, about 9,700 people die each year due to high temperature, but this is only a small part of the death toll caused by climate change, and more people die from global warming And other extreme weather brought by it, such as storms, floods and droughts.
The study also pointed out that the highest proportion of high-temperature deaths caused by climate change is in South American cities, and Honolulu has the highest proportion of high-temperature deaths caused by climate change, reaching 82%. Sao Paulo, Brazil, has the highest number of deaths due to climate-related high temperatures, with an average of 239 deaths per year.
In the United States, about 35% of high-temperature deaths can be attributed to climate change. In about 200 cities in the United States, more than 1,100 people die each year, and in New York, it is as high as 141.
Researchers said that the study shows that climate warming has seriously affected people’s health, which will also sound the alarm for mankind again, and the control of climate change is imminent.
