According to the Palo Alto School, reality constructed by communication is a second-order reality. However, such a reality is nevertheless real in the citizens’ awareness. It then follows that some unchecked or simply partial realities may have a real and full impact. This is the specific area where communication and mass media have a large influence. Therefore, it is from this perspective that we have to deal with the communication of climate change. This chapter analyzes the power of narratives to construct interpretative frameworks that legitimize the stories about climate change spread by interest groups. In this text, the importance of the narratives constructed around climate change are clarified as well as how these narratives influence the representation of real life. The agenda-setting theory, in its initial formulation and its later review, helps us to understand how the public discourses affect the citizens’ interpretation of reality. The control of narratives and interpretative frameworks, which help to make sense of events, is the communication battlefield. However, actually achieving talking about climate change in the first place is in itself a success that gives rise to hope for even greater achievements.
