Phoenix Cuts Heat Deaths 37% With Free AC and Cool Centers

When summer temperatures routinely hit 115 degrees in Phoenix, Arizona, dying from heat isn't a distant threat. It's a reality officials have fought for years to change.

Their efforts are paying off in ways that could help the entire world. After heat-related deaths in Maricopa County reached 645 in 2023, they dropped to 405 in 2024, a 37% decline that experts credit to targeted policy changes.

The county focused on the people most vulnerable to extreme heat: those with low incomes and people experiencing homelessness. Many deaths occurred among residents who couldn't afford air conditioning or had nowhere cool to go during the hottest hours.

So officials expanded access to cooling centers, keeping some open 24 hours to get people off scorching streets. They launched a program offering free repairs or replacements for broken air conditioning systems. Phoenix even became the first city in the world to hire a dedicated heat officer in 2021.

"We've had the relative benefit of knowing that this is going to be a problem every year," Maricopa County's chief medical officer Nicholas Staab told the BBC. That experience put Phoenix ahead of communities now facing deadly heat for the first time.

This summer has brought record temperatures across the US and Europe. France reported over 2,000 excess deaths during late June's heatwave. England and Wales saw an estimated 2,700 heat-related deaths since May.

The problem goes beyond health. Roads buckle in extreme heat. Flights get delayed. Entire economies suffer when temperatures soar beyond what infrastructure was designed to handle.

What makes heat particularly dangerous is that nighttime temperatures no longer cool off enough for bodies to recover. "People don't realize this is not the same heat that we were experiencing 10 years ago," Yale University researcher Jennifer Marlon explained.

The Ripple Effect

Phoenix's success story is already inspiring action elsewhere. Cities across the country are appointing their own heat officers and exploring cooling center programs.

"The world has a lot to learn from Maricopa County," Marlon says. The key is making someone specifically responsible for heat preparedness, because when it's nobody's job, nobody addresses it.

Experts stress that communities must plan for future heat, not past conditions. Records will continue to break year after year as the planet warms. Cities need to think of heat as not just a health crisis but an infrastructure and economic challenge requiring coordinated solutions.

The challenge hasn't disappeared in Phoenix either. As of mid-July this year, the county had recorded 23 confirmed heat deaths with 282 more under investigation. Keeping the downward trend going will require sustained effort and resources.

But the message from America's hottest big city is clear: deadly heat can be fought with practical solutions that put vulnerable people first.
