Discourses around climate change in Brazilian newspapers: 2003-2013.

Given the crucial role of the mass media in influencing public discourse, this study examines the discourses around climate change within the Brazilian press, covering the time period of 2003-2013. Survey evidence has shown that Brazilians' degree of concern about climate change is higher than almost anywhere else, with nine out of 10 Brazilians considering climate change a serious problem. The primary purpose of this study is to investigate how the press engendered Brazilians' striking level of climate change concern, with special attention to how the discourse developed over time. To this end, I undertake a corpus-assisted discourse analysis to examine the most dominant linguistic patterns in the discourse, presenting evidence on an unprecedented scale and with considerable depth. The corpus consists of 19,686 newspaper texts (11.4 million words) published by 12 Brazilian broadsheet papers. The results are interpreted in the light of available opinion polls on the public's perception of climate change as well as Brazil's national context and environmental governance.
