Recently, the world’s climate experts have reported that global sea level rise is speeding up much faster than they expected only a few years ago. Indeed, the rate has doubled in the past 15 years alone. Scientists estimate another rise of one to two meters before 2100. This would mean serious flooding in many sea level cities, including Washington DC, before 2050, reports Bill Blakemore at ABC News. The Jefferson Memorial (as well as other famous memorials) are on the famous Washington sea level Tidal Basin, so named because ocean tides rise and help fill it every day. It connects directly to the Potomac River and the Chesapeake Bay, an arm of the sea. Other major sea level cities, such as the Philippine capital Manila, are partly flooded frequently by ocean waters. Other cities, like St. Petersburg Russia, and some in Holland, already have extensive sea walls, which can, themselves, engender erosion. The other two adaptation strategies for city planners include elevating or redesigning structures, enhancing wetlands, or adding sand from elsewhere to beaches, or a planned retreat from the coastline.

Sea level rising toward Washington D.C., and other cities. How soon could ocean waters be lapping at Thomas Jefferson’s memorial on the edge of the Washington Mall? City planners in Washington, D.C. — and in most major coastal cities around the world — are asking such questions as sea level rise accelerates. ABC News
