Climate change causes 37% of heat-related deaths, according to a new study conducted on nearly 1,000 cities worldwide.
I climate changes are responsible for 37% of deaths due to excessive temperatures. This is what a new study published in the scientific journal reveals Nature Climate Change, conducted by researchers from the University of Bern.
A figure that could even be underestimated compared to the actual damage that climate change is causing on human health, both in terms of overheating and the emission of harmful gases.
Climate change and heat deaths
The researchers wanted to analyze the data relating to deaths in 732 cities around the world, verifying the causes of deaths between 1991 and 2018. Of all the cases analyzed, 9,700 are linked to the arising temperatures due to climate change. A figure that is equal to 37% of all deaths related to increasingly arid climates.
The city where the weight of climate change is most felt is St. Paul, in Brazil, where about 239 deaths a year are linked to changes in temperatures and climate. This is followed by the United States, where the death rate from these factors is close to 35% every single year. New York City records 141 deaths a year, out of a total US of 1,100 deaths. But Honolulu is where the proportion is highest, where 82% of deaths are linked to climate change.
Ana Vicedo-Cabrera, epidemiologist at the Institute of Social and Preventative Medicine at the University of Bern, commented on the research results:
These heat-related deaths represent a drama that could be prevented. It is something of which we ourselves are the direct cause.
The sudden rise in temperatures is connected to many health problems, starting with an increased risk of cardiovascular disorders and respirators. These consequences not only due to the increased heat, but also and above all due to the greater presence in the atmosphere of carbon dioxide and other pollutants. The researchers also point out that the study demonstrates how current the effects of global warming.
