More than a third of global warming deaths each year are directly related to global warming, according to a recent study of the cost of climate change.
But scientists say that this is just the tip of the iceberg – even more people are dying from some of the worst weather conditions developed by global warming such as hurricanes, floods and droughts – and tropical death rates will rise sharply with rising temperatures.
Many researchers looking at global warming in 732 cities around the world from 1991 to 2018 calculated that 37% were caused by high temperatures resulting from human-induced heat, according to a study that was done in the journal Nature Climate Change.
That amounts to about 9,700 people a year from the cities alone, but it is much higher than in the world, says the lead author of the study.
“This is heat-related death that can actually be prevented. It’s a very natural thing, ”said Ana Vicedo-Cabrera, a gynecologist at the Institute of Social and Preventative Medicine at the University of Bern in Switzerland.
The highest percentages of climate change caused by climate change were in cities in South America. Vicedo-Cabrera identified southern Europe and southern Asia as other tropical hotspots associated with climate change.
Sao Paulo, Brazil, has the highest death toll associated with climate change, estimated at 239 a year, researchers found.
About 35% of the deaths of tropical Americans in the United States are not suspected of climate change, the study found. That is more than 1,100 deaths a year in about 200 U.S. cities, 141 in New York. Honolulu has the highest share of climate change caused by climate change, 82%.
Scientists have used decades of mortality data in 732 cities to compile transcripts that explain how each city’s mortality rate changes with temperature and how the temperature ranges vary from city to city. Some cities are accustomed to warming better than others because of the climate, cultural and environmental conditions, Vicedo-Cabrera said.
Then the researchers took the observed temperatures and compared them with 10 computer models that mimic the earth’s immutable climate. The difference in human warming is due. By using that method that was scientifically accepted in 732 hours, the warmth resulting from climate change.
Dr. Jonathan Patz who is the director of the Global Health Institute of Wisconsin said that the people are constantly asking for evidence that climate change is affecting our health. This adjective study answers that question directly using pathological methods, and the amount of data the authors have collected for analysis is impressive.
Patz, who was not part of the study, said it was one of the first to clarify climate change related to climate change now, not in the future.
