This article centres around the creation of the ‘Climate Stories Map’ (CSM), a participatory cartographic archive strategically designed to convey the urgent reality of climate change through the lens of local narratives. Developed in collaboration with Google Berlin and built on the company’s ‘Google Maps Platform’, the project explores the potential of participatory and qualitative approaches for climate advocacy. The CSM successfully aggregates 200+ individual accounts of environmental destruction in Berlin-Brandenburg. Through its intuitive design and minimal barriers to contribution, the CSM democratises climate discourse, empowering diverse individuals to share first-hand experiences with climate change. Trialling the use of anecdotal evidence to increase engagement with the climate crisis, the CSM aims to inspire pro-environmental behaviour by emotionally connecting users with the topic and linking to local sustainability initiatives. This project fills a vital research gap and contemplates new ways to understand, communicate, and act on climate change.
