New York City is sinking under the weight of massive buildings and skyscrapers, scientists warn.
As the " New York Post " newspaper reports, citing American geologists, over a million buildings and skyscrapers have been built in the territory of the "Big Apple".
A group of scientists from the US Geological Survey (USGS) and the University of Rhode Island found that the weight of skyscrapers favors the sinking of New York's five main boroughs by one to two thousand per year. But there are also some areas that sink faster.
The head of the study, USGS geologist Tom Parsons, warns that every year that New York sinks even a millimeter, it becomes extremely vulnerable to natural disasters as climate change raises ocean levels.
If the calculations from the study are true, then it turns out that this city is sinking at a rate of about one to two millimeters per year.
That doesn't sound like much, but it should be noted that this is an average and some parts are sinking much faster, so much faster, that they are equivalent to the rates of recovery of the Earth's crust from glacial melting.
Based on the survey results, Manhattan is mostly at risk, while there is a serious concern for the boroughs of Brooklyn and Queen.
"New York faces significant challenges from the risk of flooding. The threat of sea level rise is three to four times higher than the global average along the Atlantic coast of North America…”
Changes to the foundations of the city, home to more than eight million people, could pose a threat to its low-lying areas. Therefore, the researchers emphasize that it is essential to invest in the development of mitigation strategies to address the increasing risk of flooding and sea level rise.
However, building massive seawalls may not be the best solution.
"The purpose of the paper is to raise awareness that any additional, high-rise buildings constructed in coastal, riverine, or lake environments may contribute to future flood risk," wrote geologist Tom Parsons of the US Geological Survey and his colleagues at University of Rhode Island.
