Miami Beach could be underwater this century. The sea level around the tourist paradise has risen steadily in recent decades and flooding in the streets has become more frequent and severe. Most of the city sits just four to five feet above sea level, and on a foundation of porous limestone—making it especially susceptible to tidal flooding and surging oceans.
As experts predict the sea level to rise significantly in the coming years, the city of Miami Beach must decide how to keep itself afloat. This documentary examines how the city has taken unprecedented steps to save itself from the sea.
