NEW YORK UNDER THREAT

New York, the American symbol of power, is being threatened. As a mosaic of islands surrounded by a bay along the Atlantic Ocean, the city is barely above the sea level. But global warming has put the city at risk of devastating floods, and by the end of the century, cataclysmic hurricanes could strike.  

Today, the danger is real: 400,000 New Yorkers live in flood zones. To save the city, engineers are dreaming up amazing technologies: a giant deployable wall that folds out around Manhattan, oysterbeds in the bay, or waterproof skyscrapers.    

Discover the extraordinary adventure of a remarkable city that could soon be destroyed at the hand of what created it: water.
