US-WEATHER-CLIMATE-HEALTH-HOMELESSNESS

A person protects their head from the sun while walking past a row of tents in "The Zone," a vast homeless encampment where hundreds of people reside, during a record heat wave in Phoenix, Arizona, on July 18, 2023. Phoenix, like much of the US southwest, is surrounded by desert and its 1.6 million residents are used to brutal summer temperatures. But this year's heat wave is unprecedented in its length: it has already surpassed the previous record of 18 straight days at or above 110 degrees Fahrenheit (43 degrees Celsius), with similar highs forecasted into next week. On a sidewalk in Arizona's capital Phoenix, where a record-setting heat wave has prompted warnings to limit time outside, Dana Page struggles to stay hydrated in her tarpaulin shelter. The 49-year-old, surrounded by bottles of water, knows full well the dangers heat poses to the homeless population. (Photo by Patrick T. Fallon / AFP) (Photo by PATRICK T. FALLON/AFP via Getty Images)
