#NewYorkCity May Be Sinking Under the Weight of Its #Skyscrapers
A scientific journal suggests that the city’s 1.68 trillion pounds of buildings are causing the city to descend, in some neighborhoods faster than others.

Excerpt: "The scholars first estimated the cumulative weight of New York’s buildings to be 1.68 trillion pounds, and then calculated the downward pressure these buildings exert on the mixture of clay, sand, and slit that make up most of the ground beneath the city’s streets.
"Based on their model, New York experiences a '#subsidence rate' (the technical term for sinking) of about one to two millimeters per year on average, though Lower Manhattan, as well as particular areas of Brooklyn and Queens, show a propensity for greater subsidence risk. As the authors note in their paper, much of lower Manhattan is currently no more than one to two meters above sea level, possibly exacerbating the effects of climate change in turn.
"While one to two millimeters per year may not seem that much, the study’s authors warn that this amount is more than enough to cause major coastal cities serious problems in the future. 'The combination of tectonic and anthropogenic subsidence, #SeaLevelRise, and increasing hurricane intensity imply an accelerating problem along coastal and riverfront areas,' the paper states. 'Repeated exposure of building foundations to salt water can corrode reinforcing steel and chemically weaken concrete, causing structural weakening.'
"As the study’s authors further point out, this level of annual collapse could potentially exacerbate the impact of #ExtremeWeather events like #HurricaneSandy, which saw sea water pour into New York."
