Washington, Baltimore and Philadelphia - Sea Level Rise Map
The map below shows areas near Washington, D.C., Baltimore, Philadelphia and Chesapeake Bay that will be
inundated with various levels 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 five meters will inundate thousands of acres in Maryland, Delaware, New Jersey and Virginia.
The coastal areas of Chesapeake Bay and Delaware Bay will lose a lot of valuable real estate. If you zoom in on Baltimore,
Washington, D.C., Philadelphia, Atlantic City, Ocean City, or Annapolis you will see that important portions of these cities will also be lost.
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.
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.
