New York City is sinking due to the weight of its kyscrapers according to a study published in the journal 'Earth's Future.' The study compared satellite data to the geology beneath Manhattan and it showed that the city is collapsing into the earth. NYC is sinking at a rate of 1-2 millimeters per year due to the weight of its highrise buildings. Although this may not seem like an alarming rate, some parts of the city are subsiding significantly faster than others. This is on par with the fastest understood rates at which tectonic plates rebound when glaciers melt. Study authors say the issue is encouraging the development of mitigation strategies to avoid flooding and rising sea levels. The cumulative mass of more than 1 million buildings in NYC works out to be 1.68 trillion pounds. This only includes the mass of the buildings and their contents, not roads, sidewalks, or railways. "New York is emblematic of growing coastal cities all over the world that are observed to be subsiding, meaning there is a shared global challenge of mitigation against a growing inundation hazard", Study Authors.
