More than 37% of deaths worldwide due to heat waves are directly related to global warming, according to a study published in the journal Natural climate change Monday, March 31st. According to researchers, this is a direct cause of climate change, combining heat with 100,000 deaths a year. These figures can be underestimated because some parts of the world are not particularly affected by heat waves such as Central Africa or South Asia.
To conduct this study on the cause of the effects of global warming on public health, 70 international researchers compiled data from 732 sites in 43 countries between 1991 and 2018. They then used a complex method to calculate from health data. , Temperature measurements and climate samples, the difference in the number of recorded heat-related deaths with expected deaths without warming.
In developed countries, the death toll from global warming varies from 35% to 39% in the United States, Australia, France, Great Britain, or Spain, but in countries such as Mexico, South Africa, Thailand, and Vietnam the average is more than 40%, or in Chile. In some countries, such as Brazil, Peru, Colombia, the Philippines, Kuwait or Guatemala, it is over 60%.
These results show it “Climate change is not something that comes from the distant future”, Explains Antonio Casparini, lead author of the study and professor of the London School of Hygiene and Tropical Medicine. “In addition to the already known environmental and environmental impacts, we can measure the negative impacts on health.”.
Scientists warn that heat waves will continue to increase under the impact of climate change, as it killed 70,000 people in Europe in 2003.
