Climate change-fueled heat waves are making air-conditioning a matter of life or death, especially in mobile homes. Mexican farm worker Avelino Vazquez Navarro didn’t have air conditioning in the motor home where he died last month in Washington state as temperatures surged into the triple digits.For the last dozen years, the 61-year-old spent much of the year working near Pasco, Washington, sending money to his wife and daughters in the Pacific coast state of Nayarit, Mexico, and traveling back every Christmas.Now, the family is raising money to bring his remains home.“If this motor home would have had AC and it was running, then it most likely would have helped,” said Franklin County Coroner Curtis McGary, who determined Vazquez Navarro’s death was heat-related, with alcohol intoxication as a contributing cause.Most heat-related deaths involve homeless people living outdoors.
