We study the evolution of the discourse on Spanish TV news referred the topic of Climate Change (CC) in the context of the Climate Summits in Cancun (2010) and Durban (2011). The corpus consists of the entire universe of all the records on Spanish television channels whose agenda items relates to this topic. This analysis belongs to the research project I + D Ref CSO2010-16936COMU, entitled " The Hegemonic  Discourse of Media (Risk, Uncertainly and Conflict) on "Climate Change”, and experimental testing among young people with other models of alternative discourse", and includes not only the records of informative coverage of both summits, discussed here, but also the records on the subject of climate change appeared in the news for all channels during the time between both summits. The comparison between the production of informative discourses related to climate summit, offers the opportunity to rule on the analysis of its development, whether the development of the economic crisis, which also affects the media, influences the hegemonic discourse that occurs on Climate Change. This analysis used data from the content analysis of television news records, designed in the context of R & D research referred (Teso & Aguila 2011; Piñuel & Teso, 2012). We conclude that the economic crisis affects the conditions of production in that discourse in the source selection more than the choice of subjects in the story.
