Technically, that New York City flood was “mild”
If we want to understand the full picture of climate-fueled flood risk to New York City, we can’t just look at rainfall.

Scientists who study coastal flooding actually consider NYS’s flood to be “mild.” That’s because, while the rainfall itself was record-breaking—more than 8.65 inches fell at JFK airport—the coastal flood level was only two feet above high tide.
