A new documentary called "Chasing Coral" is now playing in select theaters across the country and will premiere on "Netflix" on July 14. The film tells the story of the effort to document in real time the destruction of the world's coral reefs by the sea temperature rise caused by climate change. NewsHour Weekend's Saskia de Melker talked to the film's director about the challenge of showing the public the unseen, underwater effects of global warming.
