Europe is warming more than twice as fast as the global average—a terrifying statistic made all too apparent this summer as heat wave followed heat wave. European cities were never designed for these temperatures, and public health, infrastructure, and tourism are all under strain. Eric Klinenberg arrives in Milan just as “Europe’s third heat wave of the summer entered its fiercest stretch” and sweats his way across the continent to see how trees, shade, water, and other measures are being deployed to adapt urban centers. But with this crisis set to deepen can these experiments really keep pace?

Of all the problems that heat poses for Barcelona, losing some of the hundred and sixty thousand tourists who typically visit each day ranks low on the priority lists of most officials and residents. Some locals have staged protests, chanting “Tourists go home” while targeting visitors with water guns. But tourism employs more than a hundred and sixty thousand people in Barcelona and accounts for around thirteen per cent of its economic output, which explains why, despite concerns that the city gets too many visitors, more than seventy per cent of residents consider tourism beneficial. At midday, when I arrived on La Rambla, the city’s most heavily visited and photographed corridor, the street had little shade and surprisingly few people. At La Boqueria market, normally jam-packed at lunchtime, I found my way to a famously busy bar counter and took one of several open seats.
