As far as I can tell, the entire premise of this article is based on a model, not any empirical measurement of Manhattan actually sinking. The article then tries to distract us from examining its thin thesis too critically by connecting it to the effects of climate change. Besides, isn’t lower Manhattan made of bedrock, not sand? Nothing to see here, move on. |

As usual, ignore the article and go straight to the actual paper.[0]
"Geodetic measurements show a mean subsidence rate of 1–2 mm/year across the city that is consistent with regional post-glacial deformation, though we find some areas of significantly greater subsidence rates."
"Much of lower Manhattan lies between 1 and 2 m in elevation above sea level, and measured subsidence from Global Positioning System (GPS) there is 2.1 mm/year (Boretti, 2021)."
