Introduction
France has been preparing for climate-fueled heat waves for more than two decades. In 2003, more than 14,800 people died as summer temperatures hovered above 95°F for two weeks. The devastating event led French policymakers to build one of the world’s most comprehensive heat-resilience programs.
National Heat Plan
The following year, the French government unveiled a national heat plan that included a four-tiered alert system. When temperatures rise and trigger the highest alert level, authorities establish a crisis center to coordinate a national response. Local officials are required to implement their heat plans, which include providing access to cool spaces, ensuring access to water, and checking in on heat-vulnerable residents. France’s meteorological and health agencies jointly monitor weather forecasts and health risks, alerting residents when dangerous conditions arise.
Adaptation Measures
In the years since, France has taken additional measures to adapt to hotter summers: Cities have planted trees to reduce the urban heat island effect, built shaded walkways and biking paths, and converted public spaces into cooling centers that residents without air conditioning can use on the hottest days. (Only about 25% of French households have air conditioning.) In Paris, policymakers have conducted drills and tabletop exercises, rehearsing what it might be like to live in the future when temperatures are projected to hit 122°F.
Heat Consequences
Those strategies are now being put to one of their biggest tests. Over the past week, cities across Europe have experienced soaring temperatures, with many breaking all-time heat records. More than a dozen countries across Europe, including France, issued heat alerts over the past week, warning their residents to stay indoors during the hottest hours, keep homes cool by drawing shutters and curtains, and avoid strenuous physical activity. It’s the continent’s second heat wave in two months, both of which began even before the official start of summer. In Paris, temperatures topped 103°F, and average temperatures across France were at their highest level ever last week.
Lessons Learned
Researchers have found that as climate change drives warming, cities will increasingly have to grapple with longer summers and hotter temperatures. Europe, the world’s fastest-warming continent, is in many ways at the forefront of this challenge. For much of 2024, temperatures were 1.5°C (2.7°F) higher than preindustrial averages. On the current trajectory, temperatures in Europe are expected to rise by 5.6°F by the end of the century.
Conclusion
“Cities across the world — even the ones that are doing the best that they can — are still preparing for the heat that we’re experiencing today,” said Ladd Keith, an associate professor of planning and director of the Heat Resilience Initiative at the University of Arizona. “They’re not doing a great job of really aggressively planning for the heat that we’re going to experience tomorrow.”
