How Phoenix handles the extreme weather could become a model for other cities, especially those that are less accustomed to high temperatures but are now roiled by heat waves fueled by drought and climate change.

Two years ago, the city of Phoenix opened a small office with an annual budget of about $1 million to oversee heat response and mitigation. Since then, it has planted more shade trees; designed cool, white roadways to deflect heat; and expanded shelters for homeless people who have accounted for half of Phoenix metro’s heat-associated deaths.

Arizona’s Maricopa County, home to Phoenix, reported this week that so far this year there have been 12 confirmed heat-associated deaths going back to April, half of them people who were homeless. Another 55 deaths are under investigation.

Fueling the current heat wave is the delayed arrival of this year’s monsoon rains. The season officially begins on June 15 and can bring powerful storms with bursts of precipitation.

Despite the extreme heat, Arizona’s largest county of 4.5 million people had the biggest gain in overall population of any U.S. county last year, with a jump to almost 57,000 new residents, mostly from people moving from other states.
