New York’s Slow Sink: The Rising Threat of Coastal Cities Being Submerged by Climate Deregulation

The researchers then modeled the settling caused by the pressure of these buildings depending on the nature of the soils that support them. “We estimate settlement for surface conditions ranging from bedrock to soft soils to account for uncertainties in local geology and foundation styles”, specify the authors of the work.

Presented in the form of satellite images, the data shows a continued slump in New York, about 1 to 2 mm per year on average.

“New York is emblematic of expanding coastal cities around the world that are being watched subsiding, meaning there is a common global disaster mitigation challenge. increasing flood risk“, conclude the researchers. The issue is all the more crucial as the Big Apple, which has more than eight million inhabitants, is threatened with disappear due to the rising waters and the amplification of hurricanes and storms under the effect of climate deregulation.

But it is unfortunately not the only city that risks being swallowed up by the waters. According to the World Economic Forum, several cities around the world could be partially or totally submerged by 2050-2100: Jakarta (Indonesia), Dhaka (Bangladesh), Venice (Italy) or London (England). IPCC experts come to a similar conclusion in the first part of their sixth report, published in August 2021. According to experts, no less than 570 cities of the world would face this threat. Among them, Calcutta (India), New Orleans (United States), Alexandria (Egypt) and Bordeaux (France).
