THURSDAY, July 8, 2021 (HealthDay News) – Climate change has already become deadly enough to cause an additional 5 million deaths worldwide each year, researchers report.
“This is the first study to gain a global snapshot of mortality from sub-optimal temperature conditions between 2000 and 2019, the hottest period since the pre-industrial era,” said Yuming Guo, co-head of the study, professor at Monash University in Australia.
The results are based on an analysis of global temperature and death data from 2000 to 2019. During this period, global temperatures increased by 0.26 degrees Celsius per decade.
The authors of the study found that 9.4% of deaths worldwide could be attributed to very cold and hot temperatures, which translated into 74 additional deaths per 100,000 people, with most of the deaths being caused by the exposure to cold.
By region, annual deaths from abnormal temperatures were: Asia, 2.6 million; Africa, 1.2 million; China, 1.04 million; Europe, 835,000; United States, 173,600; South America, 141,000; India, 74,000; United Kingdom, 52,000 and Australia, 16,500.
The researchers also found that cold-related deaths decreased 0.51% from 2000 to 2019, while heat-related deaths increased 0.21%.
Deaths from hot temperatures have increased in all regions, suggesting that global warming from climate change will lead to an increase in heat-related deaths in the future, according to the new study. It was published on July 7 in The Lancet’s planetary health newspaper.
“It is important to note that we used baseline data from 43 countries on five continents with different climates, socio-economic and demographic conditions and different levels of public health infrastructure and services, so that the The study had a large and varied sample size, unlike previous studies, ”Guo said in an academic press release.
Understanding the geographic patterns of temperature-related deaths is important for developing policies and strategies to adapt to and reduce the effects of climate change, and to protect people’s health, he said.
