Penguin director gives climate warning

The French director who charmed the world and won an Oscar with his 2005 documentary March of the Penguins will close the Cannes festival on a sombre note with a film about global warming that says not only the penguins should be worried.

Luc Jacquet’s La Glace et le Ciel (The Ice and the Sky), is not in competition but will be screened after the Palme d’Or winner is announced on Sunday night.

The film is a portrait of the octogenarian French glaciologist Claude Lorius who, from the age of 23, made more than 20 polar expeditions, most of them to Antarctica.
