Abstract

This study investigates the rhetorical and ideological functions of the "global boiling" metaphor in Greenpeace International’s climate crisis discourse during 2023–2024. Using Critical Metaphor Analysis (CMA) as the theoretical framework, the research examines 13 articles published under the "#Extreme Weather" category, identifying a total of 103 metaphorical expressions categorized into four conceptual metaphors: heat/boiling is climate danger, fossil fuel companies are arsonists, climate impact is violence, and temperature thresholds as points of no return. The findings reveal that Greenpeace strategically employs metaphors to shift public discourse: from abstraction to immediacy, from natural disaster to human culpability, and from passive awareness to moral obligation. These metaphors not only translate scientific data into tangible, emotional imagery but also frame fossil fuel companies as active perpetrators of climate harm, thereby mobilizing public support for climate justice. The study contributes to a deeper understanding of how metaphorical language functions as a tool for climate advocacy and ideological persuasion.
