NYC Faces Dual Threat of Rising Oceans and Sinking Land, Study Finds

New research estimates that New York City is sinking at an average rate of 1 to 2 millimeters per year due to the weight of its buildings, homes, and infrastructure. The study warns that the city's subsidence, combined with rising sea levels, could lead to parts of the city being underwater in the future. While the process is slow, it could have destructive and deadly consequences, as demonstrated by Superstorm Sandy and Hurricane Ida. The findings could help inform policy makers as they draft ongoing plans to combat, or at least forestall, the rising tides.
