Excerpt:
More Americans died from heat in 2023 than any year in over two decades of records, according to the findings published Monday. Last year was also the globe’s hottest year on record, the latest grim milestone in a warming trend fueled by climate change.
The study, published in the American Medical Association journal JAMA, found that 2,325 people died from heat in 2023. Researchers admit that number is likely an undercount. The research adjusted for a growing and aging U.S. population, and found the death toll was still staggering.
….
Howard – along with researchers from the Uniformed Services University of the Health Sciences, in Maryland, and Pennsylvania State University – examined death certificate data between 1999 and 2023. Deaths were counted if heat was listed as an underlying or contributing cause of death.
Reported deaths remained relatively flat until around 2016, when the number of people dying began increasing, in what Howard, who studies health effects from extreme weather, calls a “hockey stick.” The hockey stick analogy has been used to describe warming global temperatures caused by climate change, where temperatures have swooped upward at alarming rates in recent years.
Howard’s study suggests the human toll follows the same outline. An important indicator is age-adjusted deaths per 100,000 people. That heat-related death rate has increased dramatically compared to the early 2000s, regardless of age or population size.
The upward trajectory appears to be sharpening recently. In 2022, 1,722 people died at an adjusted rate of 0.47. But 2023 saw 603 more deaths than the previous year, with an adjusted rate of 0.63, the highest on record.
Deaths weren’t evenly spread nationally. In an interview, Howard said deaths were overwhelmingly concentrated in traditionally hot regions: Arizona, California, Nevada and Texas.
The study is limited in how local governments classify heat-related deaths, which could mean the actual number of deaths is an undercount. It’s also potentially skewed as more people become aware of the fatal risks of heat. The study didn’t break down vulnerable groups. For example, people without air conditioning, those who live or work outdoors, and people with underlying health conditions, are all at greater risk of serious illness or death from heat.
