Nickolay Lamm has released simulated images of how parts of Washington, D.C., Miami, and New York City would look if sea levels rose by 25 additional feet - a level deemed possible in the next centuries if current trends continue.

Sea levels are probably rising faster now than they ever have in the past 3,000 years, say scientists, and the trend is expected to continue. 
In order to help people visual this problem, Nickolay Lamm with the website StorageFront.com created simulated images of how certain U.S. cities and landmarks would look with an additional 25 feet of sea level rise.
The area around the National Mall in Washington, D.C., which includes the Smithsonian and other national museums, would be submerged, as would the entire base of the Jefferson Memorial. 
Meanwhile, Miami’s South Beach would disappear almost completely, with the trunks of numerous palm trees under water.
