In this documentary Luc Jacquet discusses the scientific discoveries of Claude Lorius who left in 1957 to study the Antarctic ice.
In 1965 he was the first to be concerned by global warming and its consequences for the planet. Today, aged 82, he continues to look at the future with hope:
"I believe that men will still up.
My language is cinema. In different times, I would have made other films. But I make fierce cinema, political cinema, cinema that has no choice."
