The hotspots of sinking land referenced by Ohenen include "significant areas of critical infrastructure in New York, including JFK and LaGuardia airports and its runways, along with the railway systems," he said, adding that they're sinking by a rate of more than 2 mm a year.
Receding around these hotspots could bring damage to infrastructure and make the land more vulnerable to flooding.
“Even if that is just a few millimeters per year, you can potentially cause cracks along structures,” Ohenhen said.
In New York City, five million people and 1.8 million properties are at risk, according to the study.
