Here's what 25 feet of sea-level rise would do to the U.S. west coast

A few months ago, Pittsburgh artist Nickolay Lamm that revealed what 25 feet of sea level rise might look like at a variety of East Coast tourist destinations. Now, Lamm is back with more visions of America's watery future – but this time he's focused on the country's Pacific coastline.

Like his previous project, Lamm used maps and sea level projections from Climate Central (the same data The New York Times used to create this interactive sea-level-rise applet) to locate regions of the West Coast that models predict will be overtaken by water in the coming centuries:


Sea level rise that makes cities uninhabitable is not going to happen in our lifetime, but, it is going to happen sooner or later unless we cut carbon emissions. Our first sea level rise project covered only East Coast cities. I felt it would be fitting to bring attention to sea level rise on the West Coast as well.

Here's how the sea level is likely to change through time...

0 feet: Today's sea level

5 feet: 100 to 300 years

12 feet: Potential level in 2300

25 feet: Potential level in coming centuries

Lamm posted altered photographs of a series of West Coast landmarks under 5, 12 and 25 feet of water on his blog, which Popular Science again converted into hi-res GIFs. Check out Lamm's writeup for more photos, along with details on the process he used to illustrate the rising seas:
