This paper explores how do actors cope with their routines in the face of rhythms unpredictability. This question takes place within the context of climate change where previous taken-for-granted ecosystem rhythms are not anymore and interrogated the routines associated. To explore this question, we mobilize the concept of routine dynamics that we cross with the Lefebvre Rhythmanalysis. The we draw on a singular but representative case: the local forest planning renewing routine in a French state forest, facing current and future but still largely unknown consequences of climate change. We show that foresters are facing situation of arrhythmia, meaning situations where rhythms are not in sync and might lead the routine to collapse. To overcome those risks, the local actors are redesigning the routine in a more agile way, not to solve the rhythms’ unpredictability, but acknowledging it and coping with arrhythmia.
