Across a wide swath of the U.S. from Texas to Nevada, a major heat wave that is threatening to break temperature records continued to bake parts of the South and Southwest on Wednesday, sending people scrambling for relief and adding to what has become a series of weather extremes that researchers say fit the pattern of a warming environment.
Temperatures well into the triple digits are expected this weekend from California to Texas to Florida, with parts of Nevada forecast to reach 116 degrees Fahrenheit and cities in Arizona expected to hit a staggering 118 F.
“Today is Day 12 of 110-plus, and the exclamation on this event is yet to come,” said David Hondula, who directs the Phoenix Office of Heat Response and Mitigation, which was gearing up for a weekend spike in temperatures.
Last month was the warmest June globally since at least 1850, when record-keeping began, according to a new report by Berkeley Earth, a nonprofit research organization that focuses on climate data analysis. The report found that June 2023 broke the previous record, set last year, by a “large margin,” putting the planet on track for one of the warmest years on record — if not the warmest.
The report comes as long stretches of oppressively high heat and humidity grip much of the U.S., with those across the entire southern portion of the country bearing the brunt of extreme temperatures. And there’s no end in sight.
Hondula said his primary concern was the city’s population of people experiencing homelessness.
“We know there will be hundreds of people living on the street during this heat event and at much, much higher risk than everybody else,” Hondula said.
Last year, heat played a role in 425 deaths in Maricopa County, where Phoenix is, according to a report released this June. About 56% of the heat deaths involved people experiencing homelessness.
