Bummer: Trace amounts of CO2 may cause DC sea levels to rise "more than 16 feet by 2150"

Sea-level rise may swamp Washington D.C

Washington D.C. rose from swampy river banks and thanks the Global Warming, the good ol' days may be set to return. Sea-level rise may swamp some Washington D.C. monuments by 2150, a study suggests, unless levees surround the nation's capital.

Depending on the amount of greenhouse gases pumped into the atmosphere by burning fossil fuels, the atmosphere will warm enough to trigger anywhere from a four-inch sea level rise by 2043, on the low end, to more than 16 feet by 2150, on the high end.

"Even using a modest (sea-level rise) of 0.1 m (4 inches), the analysis of the data layers shows a relatively negative impact on the city. A total of 103 properties will be flooded," at a cost of $2.1 billion, says the study. "Above these levels, the numbers become staggering," it says next.
