This thesis explores multimodal rhetorical strategies utilised to communicate the problem of the climate crisis in the digital environment, specifically on the social media platform Instagram. To achieve this, the methodologies of Critical Discourse Analysis and Rhetorical Genre Studies are employed to analyse 24 Instagram posts from two climate activism focused Instagram accounts - 12 from each account throughout the year 2024. The research aims to illustrate the use of different digital genres, such as an Instagram carousel post or a meme, of which affordances aid in the use of particular rhetorical strategies. Additionally, the act of utilising pop-culture references as a rhetorical strategy is given an enhanced focus. These findings contribute to the understanding of how language shapes climate discourse in digital environments.
