"ST. AUGUSTINE, Fla. — America's oldest city is slowly drowning. St. Augustine's centuries-old Spanish fortress sits feet from the encroaching Atlantic, whose waters already flood the city's narrow streets about 10 times a year — a problem worsening as sea levels rise. The city relies on tourism, but visitors might someday have to wear waders at high tide.

'If you want to benefit from the fact we've been here for 450 years, you have the responsibility to look forward to the next 450,' said Bill Hamilton, whose family has lived in the city since the 1950s. 'Is St. Augustine even going to be here? We owe it to the people coming after us to leave the city in good shape.'"
