Is Charleston going underwater?

For the last hundred years, the sea level in Charleston Harbor has risen about an inch every decade. Now it's rising about an inch every two years.

Why is Charleston SC sinking?

Data from a NOAA gauge in Charleston shows that about 5 of the 12 inches of sea-level rise at the site over the past 100 years can be attributed to subsidence. It's not clear why the land is sinking. One theory: it has to do with soil compression caused by large buildings, highways and other increased development.
