IN mid-2016 the River Seine in central Paris burst its banks. It rose to 6.1 metres, briefly closed the Louvre and Musée d’Orsay, disrupted trains and affected businesses and homes. The cause: intense rainfall in much of western Europe, which led to the worst flooding in the city for 34 years. Now the waters are back.
