A new report, released by the Union of Concerned Scientists late on Tuesday, forecasts that by 2030, at least 180 floods will strike during high tides every year in Annapolis, Md. In some cases, such flooding will occur twice in a single day, since tides come in and out about two times daily. By 2045, that’s also expected be the case in Washington, D.C., Atlantic City, N.J. and 14 other East Coast and Gulf Coast locations out of 52 analyzed by the Union of Concerned Scientists.
