In recent years, we have faced a series of events that have forced us to take a stand, and this challenge continues to affect our daily lives. Some individuals have unquestioningly accepted ideas proposed and sometimes imposed by scientists and political leaders. Others tried to maintain a more balanced stance, trying to inform themselves as best they could, recognizing the need to combat the epidemic of fake news and the phenomenon of inauthentic "experts."  Meanwhile, some have joined the denialist movement, which has chosen, often ostentatiously, to openly contradict the conclusions of experts. Regardless of the stance each of us takes, some facts are undeniable today. We live in an era in which we are increasingly faced with extreme weather conditions, including extremely severe weather events and temperatures that some parts of the world have never experienced. In the face of this reality, there is only one response: act. (Matteo Paolini)
