Over the past 170 years or so, the odds that storm water would crash over Manhattan’s 5.74-foot-high Battery Park seawall lept 20-fold. In the mid-1800s the seawall would be overtopped roughly once every 100 to 400 years; between climate change and a re-engineered New York Harbor, Battery Park now faces inundation every four to five years.
New York is not the only coastal American city that faces a future of rampant flooding. And even within New York, not every part of the city is protected by a seawall. According to Climate Central, reporting on a new study, the damp future of climate change-enhanced flooding will be here for large parts of the country far sooner than scientists previously thought.
