Code Red for Humanity: Multimodal Metaphor and Metonymy in Noncommercial Advertisements on Environmental Awareness and Activism

Abstract

Concern for global warming, climate change and pollution has grown in recent years, with countries across the world facing natural disasters on unprecedented scales. The communication of environmental protection is therefore a necessary area of enquiry, especially from a Conceptual Metaphor Theory perspective. The present article explores (1) how the themes of global warming, climate change, pollution and activism are conceptualized in a corpus of 51 noncommercial advertisements, (2) the interaction of metonymy with metaphor, (3) the distribution across verbal and visual modes of metaphoric source and target domains, and (4) how value is evoked. Findings show that half of the corpus frames environmental themes through source domains such as weapons, predators and natural disasters. The other half triggers incongruous mappings, such as between concrete entities, and relies on metonymic processes of inference to access the main rhetorical message. Among the most frequent metonymies, CAUSE-EFFECT and CATEGORY FOR SALIENT PROPERTY highlight the negative effects of the represented phenomena. Multimodality usually occurs within source and/or target domains rather than across the metaphoric mapping. Most of the campaigns project mixed value, where a negative evaluation of a theme is accompanied by a positive message, inviting the audience to take action.
