A recent study published in Nature Cities reveals that New York City is experiencing significant land subsidence, primarily due to climate change, groundwater depletion, and urban weight. With an overwhelming 98% of its land subsiding, some areas like LaGuardia Airport are sinking over 5mm annually. This poses grave risks for flood zones, infrastructure, and the vast population residing in vulnerable areas. Without intervention, the city's defenses against rising sea levels weaken, leading to greater flooding risks and potential damage to critical infrastructure in the future.
The intersection of land sinking and rising sea levels means storm surges will push further inland, creating a significant risk for low-lying areas.
A new study reveals that NYC's subsiding land places the entire city—and much of its infrastructure—at heightened risk of flooding due to climate change.
Researchers warn that 98-percent of NYC's land is subsiding, posing increased risks of flood damage as sea levels rise alongside the city's sinking land.
The combination of urban weight and climate factors has led to parts of NYC sinking at alarming rates, with LaGuardia Airport seeing more than 5mm of subsidence.
