New Orleans and the Gulf Coast - Sea Level Rise Map



Use the window in the top left of the map frame to change the amount of sea level rise.





The map above shows areas of the Texas, Louisiana, Mississippi and Alabama coastlines that would be flooded at various stages of sea level rise. You can select a value of sea level rise using the dropdown box in the upper left corner of the map. The navigation buttons can be used to zoom in/out and pan across the map.

The map clearly shows that a sea level rise of only a few meters would inundate thousands of acres of highly developed land, beach communities and habitat along the Gulf Coast. If you zoom in on New Orleans, Morgan City, Lake Charles, Port Arthur, Mobile, Galveston, Freeport or other areas you can see communities, railroads, ports, factories, refineries and other types of land use that will be under water. The United States Gulf coast will be one of the hardest areas hit if sea level rise associated with global warming continues.

This map is not a carefully surveyed and extremely accurate presentation. It is intended to provide a visual impression of which geographic areas might be flooded if global warming and climate change continue unabated.

Elevations in urban areas shown on the map may be higher than actual values due to radar reflections from the tops of buildings and other structures. This would result in flooding being more severe than shown on this map. For an interesting presentation of how sea level rise might impact important cities, see U.S. Cities We Could Lose to the Sea at Climate Central.org.

This sea level rise map was created by Alex Tingle of firetree.net using the Google Maps API, NASA data and lots of programming savvy. He explains how the map was created, the sea level data and issues about map accuracy here. He also provides an impressive, full-monitor, global sea-level rise map on his website. We thank Alex for allowing us to share this map on Geology.com. Also thanks to Google and NASA for providing the resources needed to make this map.
