Ho Plaza - New York City
The trees in Ho Plaza represent the estimated sea level rise in New York City between the years 2025 and 2250. The increases range from 9 inches in 2025 to 7.5 feet in 2250. Even slight sea level increases will increase the risk of storm related floods. A sea level rise of 3 feet would flood Lower Manhattan, including Wall Street, as well as flood subways, airports, and coastal areas.
