Summary

In this interview, Jean-Marc Jancovici discusses the accelerating climate crisis and the inevitable decline of fossil fuels. He argues that recent extreme weather events, such as heatwaves and wildfires, were predictable and are a sign of things to come. He emphasizes that France is not prepared for these changes, as its infrastructure, agriculture, and forests were designed for a stable climate. He also addresses geopolitical tensions over resources, the impossibility of true energy sovereignty, and the need for difficult choices between competing priorities. Jancovici criticizes political elites for their lack of awareness of material constraints and calls for a collective effort to organize a planned reduction in energy consumption. He discusses the role of technology, the challenges of financing adaptation, and the importance of social justice in implementing necessary measures.
