$10 BILLION plan to save Manhattan from rising sea levels

New York City Mayor Bill de Blasio has revealed a plan to protect Lower Manhattan from rising sea levels by surrounding it with earthen berms and extending its shoreline by as much as 500 feet. And by 2100, it says this will rise to almost 50 percent. De Blasio’s new plan aims to combat an estimated six feet of sea level rise that’s expected to encroach upon the city by the end of the century.
