(FILES) A nurse cools down elderly persons with a water sprayer in a room of a geriatric hospital as temperatures in France were expected to hit a peak today, according to the Meteo France weather agency, with some areas expected to soar beyond 40 degrees Celsius (104 degrees Fahrenheit), in Lyon on July 1, 2025. Global warming will expose the elderly to a rise in temperatures even more dangerous than anticipated over the coming decades, according to a study published on August 18, 2026 in The Lancet Planetary Health.
