The Huffington Post is showcasing a new film from Oscar-winner Charles Ferguson, entitled: "Time to Choose."
Ferguson's documentary examines the climate-change crisis, offering some stark realities of rising global temperatures. If the Greenland ice sheets melt, the film notes, sea levels will rise 23-feet, threatening New York, Shanghai, Mumbai, Istanbul and every other coastal city on the planet.
"I don't think most citizens in the world have really grasped what is happening -- and what these risks are," says Dr. Steven Chu, former US Secretary of Energy, in a clip from the documentary. "Many of our major cities will be submerged."
The film, which debuted in September at the Telluride Film Festival, will be screened at two special events in Paris during the UN climate-change conference.
