There’s been a bit of dire news regarding global warming floating about recently. We realize that there are competing views on whether global warming is an actual threat, but with icebergs the size of Texas and Arizona breaking away from the Arctic icepack (jeopardizing the journey to the North Pole via the Polar Express) and National Geographic saying that by the end of the century global coastlines could be significantly inundated (book your travel to the Maldives and Kiribati now), it’s interesting to ask some What Ifs regarding the nation’s capital, which is lovingly called Swamp City by some. Even during minor hurricanes that sweep through the Chesapeake Bay area, like Hurricane Isabel of last year, low-lying areas in Georgetown and Alexandria can easily flood, but most of Washington is high and out of reach from the clutches of tidal surges. But that doesn’t include the monumental core, which was reclaimed from tidal flats early last century.
