The Union of Concerned Scientists have produced this extensive report on the probably impact of rising seas on many of our nation’s coastal communities including Charleston. To see the section specifically about Charleston go to page 29 of the full report.
Here is an excerpt:
“By 2045, under the same mid-range scenario, Charleston would see more than 180 tidal floods a year. And because sea levels will be higher, flooding would be more extensive and persist for about 400 hours a year. Under rising seas, an average high tide could inundate the historic district and flood low-lying neighborhoods as often as every other day.”
