New York to be wiped out of American map? How can great American city survive?

New York is facing its greatest challenge in guise of flooding and the rising sea level. New York's adaptation is a matter of survival. Climate experts have recommended several strategies. The city could increase its ability to absorb water, converting wide areas of asphalt and concrete to green space. It could fortify by building barriers along its shores, possibly even a gate around the harbor. Or it could retreat, relocating people out of the most hazardous regions, as per a report.

The city will most likely have to embrace all three approaches in some form. New York is experiencing extreme rainfall events with increasing frequency and intensity, according to a 2024 study in Nature, NYT News Service reported.

Since 1970, the city's stormwater system has been built to handle up to 1.75 inches of rain per hour. Hourly precipitation recorded by Central Park's rain gauge didn't exceed this limit until 1995. It's been eclipsed in three of the last five years.


One major problem is how little of that rainfall is absorbed or stored before reaching the stormwater system. A whole suite of solutions focuses on building and expanding the city's capacity to do so.

Understanding New York's historical environment is crucial to imagining a more resilient urban future, one based on the city's past topography, according to Eric Sanderson, a landscape ecologist and vice president for Urban Conservation Strategy at the New York Botanical Garden and the author of "Mannahatta: A Natural History of New York City."

Today, only about 30 per cent of the city's surface area is composed of absorbent surfaces. The rest is covered by impervious surfaces that replaced what were originally more porous landscapes, according to Sanderson's research.

Rain-based and tidal flooding risks were estimated with data from the New York City Stormwater Flood Map using the "Extreme Flood With 2080 Sea Level Rise" scenario. The sea level rise used for this scenario was the 2080s high estimate of plus-4.8 feet from current sea level. For rain-based risk, only areas that fell into the "Deep and Contiguous Flooding (one foot and greater)" category were included.

Additional flooding risk from storm surge was estimated with data from the New York City Flood Hazard Mapper using the "Future Floodplain of the 2080s" layer. Projections are based on 90th-percentile projections released by the New York City Panel on Climate Change in 2015.

Estimates of the population living in the areas at risk of future flooding were based on nighttime population estimates from LandScan USA 2021. Population density was visualized with data from the Facebook Connectivity Lab and Center for International Earth Science Information Network (CIESIN) Columbia University, accessed via Humanitarian Data Exchange.

The study on trends in hourly precipitation data in New York City was published in 2024 in Nature by Mossel et al, and the data was accessed via National Centers for Environmental Information. Impervious surface data is from NOAA's C-CAP High-Resolution Land Cover program. Maps/data on the historical ecological landscape of New York City are from Eric W. Sanderson's "Before New York: An Atlas and Gazetteer" (Abrams, 2026), courtesy of the New York Botanical Garden.

Data on storm surge risk for 2095, proposed infrastructure, and residual risk under various scenarios are from the U.S. Army Corps of Engineers "New York-New Jersey Harbor and Tributaries Focus Area Feasibility Study." Elevation data for New York City is from the 2017 New York City LiDAR Capture via the NYS GIS Clearinghouse.
