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

New York faces its biggest challenges, including flooding and rising sea levels. New York’s adaptation is a matter of survival. Climate experts have suggested various strategies. The city can increase its ability to absorb water by converting large areas of asphalt and concrete into green space. It could fortify it by building barriers along its coasts, possibly even a gate around the harbour. Or it could retreat and move people away from the most dangerous areas, according to one report.

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

Since 1970, the city’s stormwater system has been built to withstand 1.75 inches of rain per hour. The hourly rainfall recorded by Central Park’s rain gauge did not exceed this limit until 1995. There has been an eclipse in three of the last five years.
One major issue is how little of the precipitation is absorbed or stored before it reaches the stormwater system. A number of solutions focus on building and expanding the city’s capacity to do this.

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

Today, only 30 percent of the city’s surface area consists of absorbent surfaces. The rest, Sanderson’s research shows, is covered with impermeable surfaces that have replaced what were originally more porous landscapes.
Rainfall and tidal flood risks were estimated with data from the New York City Stormwater Flood Map using the “Extreme Flooding with 2080 Sea Level Rise” scenario. The sea level rise used for this scenario was 4.8 feet above current sea level plus the highest estimate for the 2080s. For rainfall-based risk, only areas falling into the “Deep and Contiguous Flood (one foot and greater)” category were included. Additional flood risk from storm surge was estimated with data from the New York City Flood Hazard Mapper using the “2080s Future Floodplain” layer. The projections are based on 90 percentile estimates published by the New York City Climate Change Panel in 2015.

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

The study of trends in hourly precipitation data in New York City was published by Mossel and colleagues in the journal Nature in 2024, and the data was accessed through the National Centers for Environmental Information. Impervious surface data are from NOAA’s C-CAP High Resolution Land Cover program. Maps/data on the historic 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 2095 storm surge risk, proposed infrastructure, and residual risk under various scenarios were obtained from the U.S. Army Corps of Engineers’ “New York-New Jersey Port and Tributaries Focus Area Feasibility Study.” Elevation data for New York City is from the 2017 New York City LiDAR Capture via NYS GIS Clearinghouse.
