How is the digital platform society changing our perception of climate change — and who is shaping public knowledge about it today? This dissertation examines how visual communication practices, new groups of actors, and the use of generative AI are transforming climate communication on TikTok, Instagram, and YouTube. It shows how visibility, authority, and trust (…)

This dissertation project uses sociological discourse analysis to examine how the RKK draws organizational boundaries, communicates these both internally and externally, and what consequences this has for the institution’s relationship with its members. The focus is on the public communicative positioning of actors within the RKK who operate at various organizational levels.

Machine learning is increasingly being used in communication studies, especially for tasks that previously could only (…)
