- Rising sea levels threaten to submerge entire cities by 2100.
- The cities most vulnerable to flooding in the US are low-lying coastal areas.
- If the worst projections of sea-level rise wind up being correct, cities like Miami and New Orleans could find themselves underwater.
No city is immune to the effects of a warming world, but a few are more vulnerable than the rest.
As sea levels continue to rise, low-lying coastal cities can expect more devastating floods that ruin buildings, destroy infrastructure, and claim lives.
By conservative estimates, cities around the world could witness more than 6 feet of flooding by the year 2100. The National Oceanic and Atmospheric Administration (NOAA) has predicted that sea levels could rise by 10 to 12 feet if global emissions continue unabated.
But these numbers are averages, which means some areas would see higher levels, while others would be less affected. Under the worst-case climate scenario, some cities might even disappear underwater.
Though it’s possible for cities to install new infrastructure and artificial barriers to protect themselves from climate change, time is running out. Here are the 7 cities in the US most likely to disappear underwater by 2100.

New Orleans still hasn’t fully recovered from the catastrophic damage of Hurricane Katrina in 2005.
The city’s location on a river delta makes it vulnerable to flooding and sea-level rise. Some areas lie 15 feet below sea level. Though wetlands have shielded New Orleans from storm surges in the past, that buffer has gradually been destroyed by human activity.
Much of the city’s land is already sinking. A 2016 NASA study found that certain parts of New Orleans are sinking at a rate of 2 inches per year, putting them on track to be underwater by 2100.
