In this episode, journalist Yolaine de la Bigne meets Jean Jouzel. This tireless climatologist and glaciologist, Nobel Peace Prize winner for his work at the IPCC in 2007, has been educating policymakers, industrialists and public opinion on the urgency of the ecological situation for over thirty years. Together they talk about the Sixth Extinction, the countdown to save the world, climate change sceptics, and progress as a possible solution. Jean Jouzel gives us his view of climate transition and tomorrow’s world.
