Extreme heat waves in 2026 caused significant health risks, including heat-related illnesses and fatalities, with 40 deaths reported during the Fourth of July heat dome. Infrastructure was heavily impacted, with nearly one million people losing power and artificial turf temperatures reaching 157°F (69°C) during a football game in Nashville. Wildfire smoke further exacerbated air quality issues, affecting nearly one-third of the population. Vulnerable groups, such as children, the elderly, and low-income households, faced heightened risks due to inadequate cooling systems and rising energy costs. These events underscore the urgent need for resilience measures to mitigate the effects of extreme heat.
