How Paris is using the Seine to try to keep cool in scorching heat

Paris uses a 75-mile district cooling network operated by Fraicheur de Paris to chill water from the Seine and supply air conditioning to buildings, reducing electricity use and emissions by 50% compared to standalone systems. The system faces strain during Europe's current heatwave, which has caused closures at landmarks like the Louvre and Eiffel Tower and disrupted transport and agriculture.
