‘Sinking Cities’ shows how Earth’s large coastal cities prepare for future survival

As our planet warms, sea levels rise and super-storms become more frequent and intense, many major coastal cities could soon be under water.

“Sinking Cities” is a four-part miniseries coming to Arizona PBS Wednesdays at 9 p.m. The show chronicles how New York, London, Tokyo and Miami are preparing for the real-time impact of rising seas by devising colossal new construction projects and technological safety measures. These and other ground-breaking solutions are all aimed at securing their future from rising tides and future floods fueled by global warming.
