00:01The ocean isn't creeping in anymore, it's moving fast, and for millions of Americans, the water's already at the door.
00:07These five U.S. coastal cities are on the front lines of rising seas.
00:11Number five, Virginia Beach, Virginia, one of the fastest sea level rise zones on the East Coast, with more than
00:1535,000 flood-prone homes.
00:18Number four, Galveston, Texas, a barrier island facing the open gulf.
00:22Even with a 17-foot seawall, higher seas let storm surge reach further inland.
00:27Number three, Charleston, South Carolina.
00:30Historic streets now flood more than 50 times a year from tides, rain, and storm surge.
00:35Number two, New Orleans, Louisiana.
00:37Half the city lies below sea level.
00:39Rising oceans increase pressure on levees, making major storms more dangerous.
00:44And number one, Miami Beach, Florida.
00:46Just feet above sea level, flooding now happens even on calm, sunny days.
00:50Sea levels could rise up to 17 inches by 2040.
