The project named "Warning!" has reached its sixth edition. "Warning!" was born in 2020 with the aim of developing interdisciplinary educational paths on the topics of major planetary dangers and environmental fragility. This project was conceived as a knowledge dissemination initiative with a specific focus on high-school students. "Warning!" has been repeated in the following years, proposing different themes for discussion, but maintaining the interdisciplinary approach and always underlining the centrality of the scientific method in facing complex problems. Each cycle was composed of four or five debates in which experts from different disciplines addressed the topic under discussion from different points of view. Physics was the "fil rouge" that accompanied the participants on this journey across many fields of science.
