Rising Seas to Destroy U.S. Beaches

Breaking Earth News

A new study of the potential sand losses to North Carolina beaches reports that a 1-foot rise in sea level in the next 25 to 75 years (which is at the lower end of the range predicted by the Intergovernmental Panel on Climate Change) would cause the coast to move inland by 2,000 to 10,000 feet and could cost an estimated $223 million in lost recreational value by 2080 to beach-goers in that state alone.
Predicting exactly how much beaches will shrink is impossible because beach erosion rates are highly variable, even between points that are only a few miles apart. The make-up of each beach's sand, the absence or presence of jetties and other man-made structures meant to retain sand, and offshore topography (which influences wave formation), all affect erosion rates.
But even with all the uncertainty, scientists say the future of our beloved sandy havens doesn’t look good.
