A pioneering glaciologist, Claude Lorius had already warned the world about climate change in the 60s. While these issues are now being discussed at the Paris Climate Conference, a new film explores his life.
Leaders negotiating the future of the planet at the 2015 Paris Climate Conference should watch "Ice and the Sky," a documentary which demonstrates without a doubt our role in global warming.
The film tells the story of the climatologist Claude Lorius, now in his 80s, who demonstrated long ago the connection between climate change and CO2 emissions through his research on glaciers.
Filmmaker Luc Jacquet, who received an Oscar for "March of the Penguins," returned to the Antartic to direct this documentary, which aims to challenge everyone who still denies global warming.
The film concludes with a direct question: "Now that you know, what are you going to do about it?"
