Cities from Paris to Barcelona are staging elaborate drills to prepare for extreme heat waves made more likely by climate change. These exercises test emergency responses, infrastructure, and public awareness amid warnings of deadly temperatures ahead. Officials say the simulations reveal critical weaknesses before real crises hit.
In October 2023, Paris held a major simulation called Paris at 50 degrees Celsius, imagining temperatures reaching 122 degrees Fahrenheit (50 degrees Celsius). Around 70 children role-played heat-related illnesses in a cool underground tunnel, while firefighters, officials, and Red Cross workers managed simulated chaos from power outages and hospital overloads. The €200,000 exercise involved over 100 organizations and produced 50 recommendations now integrated into the city's 2024–2030 Climate Action Plan, including home insulation and tree planting, Pénélope Komitès, Paris deputy mayor for resilience, said. “It was very important for us to show people that heat waves are not just something we see on the TV, but something that can happen soon,” Komitès told Grist. The drill also led to the opening of a Campus of Resilience in March for public training sessions. Scientists warn such heat could become reality by 2100, with Paris's record at 108.68 degrees Fahrenheit in 2019. Modeling projects 1.6 billion people in nearly 1,000 cities facing perilous conditions within three decades. Barcelona is adapting Paris's model to test waste management and coordination at 40-50 degrees Celsius, Irma Ventayol, head of the city's climate change department, said. “Can we cope with waste management at 40 degrees C or 50 degrees C? Are the trucks prepared?” she asked. Taiwan plans a live simulation in July for a 104-degree Fahrenheit heat wave, following a tabletop exercise last year, Ken-Mu Chang of the Climate Change Administration noted. Experts like Dr. Satchit Balsari of Harvard Medical School emphasize simulations expose gaps in implementation and funding. Cassie Sunderland of C40 says they must pair with efforts to cool cities and cut emissions.
