Rising Sea level


TIME GRAPHIC EXHIBIT E: Rising Sea Levels

Cape Hatteras Lighthouse was 1,500 ft. from the North Carolina shoreline when it was built in 1870. By the late 1980s the ocean had crept to within 160 ft., and the lighthouse had to be moved to avoid collapse.

Japanese fortifications were built on Kosrae Island in the southwest Pacific Ocean during World War II to guard against U.S. Marines' invading the beach. Today the fortifications are awash at high tide.

Florida farmland up to 1,000 ft. inland from Biscayne Bay is being infiltrated by salt water, rendering the land too toxic for crops. Salt water is also nibbling at the edges of farms on Maryland¹s Eastern Shore.

Brazilian shoreline in the region of Recife receded more than 6 ft. a year from 1915 to 1950 and more than 8 ft. a year from 1985 to 1995.
