ABC: New York City is among the most densely populated coastal communities in the world preparing for an inevitable rise in sea levels, which scientists said will amplify flooding crises from events such as thunderstorms, high tides and hurricanes.

Sea levels in New York City are expected to rise between 8 inches and 30 inches by the 2050s and as much as 15 inches to 75 inches by the end of the century, according to The NYC Panel on Climate Change.

About 1.3 million residents of New York City live within or directly adjacent to the floodplain, according to Rebuild by Design, a climate research and development group. As sea levels continue to rise, that number could increase to 2.2 million New Yorkers.

The consequences of sea level rise were displayed in 2012, when Superstorm Sandy, a Category 3 storm at its peak intensity, hit New York City as a tropical storm. The system, coupled with high tide, sent a storm surge from the East River into lower Manhattan — more than 9 feet above normal tide levels in Battery Park, while the depth of floodwaters measured at 14 feet in Staten Island, according to a report by the city.
