Deadly ‘Wet-Bulb’ Temperatures Are Smothering the Eastern U.S.

The article discusses the increasing prevalence of deadly "wet-bulb" temperatures in the eastern United States. Wet-bulb temperature is a measure of heat and humidity that can be life-threatening to humans. As climate change progresses, these extreme heat conditions are becoming more common, posing serious risks to public health. The article cites recent heatwaves that have led to numerous heat-related illnesses and deaths in the region. It explains that when wet-bulb temperatures exceed 95°F, the human body can no longer effectively cool itself through sweating, leading to potentially fatal outcomes. The article highlights the disproportionate impact on vulnerable populations, such as the elderly, outdoor workers, and those without access to air conditioning. It also notes the broader societal and economic consequences of these extreme heat events, including strain on infrastructure and public services. The article emphasizes the urgent need for strategies to mitigate and adapt to the growing threat of wet-bulb temperatures, including improving infrastructure, expanding access to cooling, and addressing the underlying causes of climate change.
