[Interview] ‘I cannot be optimistic,’ says climatologist Jean Jouzel

Jean Jouzel, a French climatologist, expresses concern over the insufficient global efforts to combat climate change, despite some progress. He emphasizes the need for a robust strategy to achieve carbon neutrality by 2040 to stabilize the climate. Jouzel highlights the importance of transitioning to sustainable economic systems, particularly through electric vehicles and energy efficiency in buildings. He notes that misinformation about climate change is prevalent, complicating public understanding and action.
