Two papers landed the same day. An attribution analysis puts children aged 0–9 at roughly three times the added humid-heat exposure of people in their sixties; a German cohort counts the emergency visits.
An analysis of insurance claims from 2016 to 2023 found extreme heat consistently drove up emergency department use and cost across commercial, Medicaid, and Medicare Advantage plans.
A meta-analysis spanning two decades of research found extreme cold carried a higher relative risk of death than extreme heat or heatwaves — even as warming shifts public attention toward summer temperatures.
