NPR is reporting that a two-year investigation, conducted with researchers from Boston University, has revealed a significantly higher number of heat-related deaths in the United States than official federal records indicate. It said the collaborative effort, which also involved NPR’s Investigations team, found that heat contributes to the deaths of approximately 9,000 Americans each year. This figure is roughly five times greater than what federal records currently state.
The investigation utilized sophisticated statistical modeling to arrive at its estimate. NPR highlighted that the impacts of heat are larger than previously suggested by official counts, a sentiment echoed by experts, doctors and epidemiologists who felt official numbers did not align with their experiences.
NPR noted that human-caused climate change is making summers hotter and more intense, exacerbating the problem. Quinn Adams, an epidemiologist at Boston University and a partner in the research, emphasized that "Every heat death is preventable," adding that understanding the scale of the problem is the crucial first step. NPR plans to continue its coverage over the coming months, sharing stories of individuals lost to heat and exploring solutions aimed at preventing future fatalities.
