Ladd Keith, who leads the Heat Resilience Initiative at the University of Arizona, explained to the BBC that cities worldwide could follow Phoenix’s example by designating a heat officer – an official tasked with coordinating heat-related initiatives and facilitating communication across government departments.
“Assigning clear responsibility for heat management is crucial,” he emphasized. “When no one is specifically accountable, action on heat risks tends to fall through the cracks.”
“Through effective coordination and communication, cities can establish cooling centers even in regions unaccustomed to extreme heat,” noted Marlon. “Such facilities are vital for protecting vulnerable populations during heatwaves.”
“However, implementing such measures requires broad recognition that extreme heat poses a serious, ongoing threat — not a fleeting problem,” experts caution. “Without this understanding, efforts to build heat resilience will lack the necessary support.”
Human-driven climate change has intensified heatwaves, making them more frequent, severe, and prolonged. Global temperatures have already risen by over 1.1°C since pre-industrial times, and this warming trend will persist for decades even if nations implement aggressive emission reduction strategies.
Experts stress that municipal leaders must recognize heat as a multifaceted challenge extending beyond public health — it significantly impacts urban infrastructure and economic stability as well.
“We can expect ongoing damage to infrastructure, such as buckled roads and flight disruptions, as extreme heat events become more common,” warned Marlon.
“Above all,” Keith emphasized, “it is essential that the public recognizes these extreme heat conditions are not temporary but will persist and intensify.”
“Our planning must evolve beyond historical heat patterns,” he stated. “We need to prepare for the heightened temperatures projected over the coming five to ten years.”
“If current heat levels feel severe, brace for worse: temperatures will climb higher and extreme heat will last longer. Breaking annual heat records is likely to become a global norm,” he added.
