If the skyscrapers of New York point upwards, scientists are beginning to be more interested in what is happening below, in the foundations. Worried about the pressure exerted by these towers on the city’s soil. They even calculated their number. There are a total of 1,068,954 buildings, with a total weight of 762 million tons. They concluded that New York is sinking on average by one to two millimeters per year, up to five millimeters in the most threatened neighborhoods. It is not easy to show this subsidence concretely, except with the tower that we see in the images. It leans eight centimeters towards its north side. It’s imperceptible to the naked eye, but that’s, in part, because of these foundation problems. This subsidence constitutes a problem that is all the more serious as it is combined with another worrying phenomenon, rising water levels. As a result of climate change, the city is experiencing more and more extreme weather episodes. As with the deadly hurricanes Sandy in 2012, or Ida in 2021. New York was flooded each time.
