The first Student Activity of the Climate Truth Crisis collaboration took place from 7 to 11 April 2025 at the Estonian Academy of Arts in Tallinn. It was organized in cooperation with the EKA Graphic Design Department and the Department of Semiotics of the University of Tartu. Students were supervised by semioticians, conspiracy theory and disinformation researchers Mari-Liis Madisson and Daniel Tamm, Laura Vilbiks from the Estonian Foundation for Nature (ELF), and graphic designers Laura Merendi, Ott Kagovere and Kert Viiart.

The event in Tallinn focused on language and framing, and specifically on developing a visual glossary. During day one of the five-day workshop students were introduced to the concept of semiotics and sense-making, while day two provided insights into the meaning-making processes within conspiracy theories. On day three, climate policy expert Laura Vilbiks elaborated on the impact of climate disinformation on public opinion and climate action.
