Heat-Related Deaths Surge in Maricopa County Amid Record Temperatures

Maricopa County, home to Phoenix, has reported 27 confirmed heat-related deaths this year, with an additional 396 deaths suspected to be linked to extreme heat, according to data released on Tuesday. This alarming trend follows last year’s record of 645 heat-related fatalities, marking the deadliest year since tracking began in 2006. Notably, nearly half of last year’s deaths occurred during a severe heatwave from July 10 to July 25, a period that saw fewer investigations than the current year. The recent spike in suspected heat deaths coincides with soaring temperatures, particularly during the week of July 7 to 13, when Phoenix recorded highs of 118 degrees. Experts attribute this increase to the dangerous conditions expected in a warming world, exacerbated by fossil fuel pollution. Nick Staab, assistant medical director of Maricopa County public health, emphasized the established correlation between rising temperatures and increased heat-related illnesses and fatalities. This June was hotter than the previous year, and July is on track to match last July, which was the hottest month recorded in any U.S. city. Researchers have noted that mortality records often overlook other heat-related causes, such as heart attacks. In response, Maricopa County has revised its investigation methods to allow for multiple contributing factors in heat-related deaths, addressing previous undercounts. As summer continues, officials warn that the high number of suspected heat-related deaths could rise further, indicating that the most dangerous months are still ahead.
