This paper argues that, to tackle the issue of sustainability, we should pay more attention to the temporality of socioecological processes. Only thus can we better understand current subjective and institutional constraints, as well as envision new potential pathways for transformative change. Two main arguments are developed: (1) there is a uniqueness in the temporality of Earth system processes associated with planetary boundaries that deeply transforms our time horizon and the pace of change, and (2) this situation creates a disruption (...) of the temporality embodied in dominant sociopolitical conventions such as the institutional definition and operationalisation of sustainable development. New research avenues and time policies are suggested towards responding meaningfully to the alarming current socioenvironmental trends. (shrink)
