The researchers calculated the mass of the 1,084,954 buildings that existed across the five boroughs of New York City at the time, reaching the conclusion that they weighed about 1.68 trillion pounds (762 billion kilograms) - equivalent to roughly 1.9 million fully loaded Boeing 747-400s. The paper, published in the journal Earth’s Future, aims to show how high-rise buildings in coastal, riverfront or lakefront areas could contribute to future flood risk and that measures should be taken to mitigate the potentially hazardous impacts. “But we’ve had a couple of major hurricane events with Sandy and Ida in New York where heavy rainfall caused inundation in the city, and some of the effects of urbanization have allowed water to come in.” “We’re a ways off from the ocean simply moving in,” said lead study author Tom Parsons, a research geophysicist at the US Geological Survey. What’s more, scientists expect more frequent and extreme rainfall events such as nor’easters and hurricanes due to the human-fueled climate crisis. This gradual process could spell trouble for a city around which the sea level has been rising more than twice as fast as the global rate - and is projected to rise between 8 inches and 30 inches by 2050. New York City is sinking under the collective weight of all of its buildings, a new study has found.
