Eight Heat Waves That Forced Cities to Redesign Infrastructure

A Quartz article examines eight historic heat waves that compelled cities to overhaul building codes, emergency systems, and urban planning. The 1987 Athens heat wave (41.9°C, 1,300–1,500 deaths) led to widespread air conditioning adoption and Greece's text alert system. Chicago's 1995 disaster (739 deaths) produced the city's Extreme Weather Operations Plan and green roof initiatives. France's 2003 heat wave (14,802 deaths) created the Plan Canicule, mandating cool rooms in nursing homes. Melbourne's 2009 heat wave (374 excess deaths) spurred the Excess Heat Factor index and catastrophic fire danger ratings. Ahmedabad's 2010 heat wave (1,344 deaths) resulted in South Asia's first Heat Action Plan and Cool Roofs Program. Moscow's 2010 heat wave (11,000 excess deaths) prompted cooling centers and peatland restoration. The 2021 Pacific Northwest heat dome (619 deaths in British Columbia) led Oregon to mandate landlord permission for portable AC units and upgrade building codes. The UK's 2022 heat wave (40.3°C) exposed gaps in Part O building regulations, which now require passive cooling in new homes.
