Climate Autobiography Timeline: Adapting Timeline Research Methods to the Study of Climate Perceptions

Abstract Climate perception is a growing area of study in the social sciences, and one which has implications on the tools and strategies we use to communicate climate change risk information. However, the range of climate perception studies remains limited, focused primarily on perceptions of day-to-day weather, sudden-onset severe events, or long-term permanent change. Phenomena situated between these extremes (e.g., annual- to decadal-scale variability) is largely missing from social science of climate research. Whether this is due to limited perception by research participants, limited research attention, or is a reflection of the methods commonly applied to human dimensions of climate research, this gap precludes analysis of the full range of complex climate experiences and their influence on climate perception and understanding. In this paper, we offer a proof of concept for the Climate Autobiography Timeline (CAT), a visual timeline tool developed to assess climate perception while prompting an ordered consideration of time, with the goal of eliciting insights into complex and long-term climate experiences such as low-frequency climate variability. Results are based off a preliminary application of the CAT across focus groups conducted in Newfoundland and Labrador, a province subject to low-frequency climate variability and frequent high-impact weather. Results reveal three key findings 1) weather and climate narratives are commonly anchored to two time periods, potentially obscuring perceptions of variability; 2) narratives focus on socially important weather and climate phenomena; and 3) the social and visual co-construction of weather and climate narratives may yield more holistic representations of local climate knowledge.
