The Anthropocene has yet to be defined in a way that is functional both to the international geological commu- nity and to the broader fields of environmental and social sciences. Formally defining the Anthropocene as a chro- nostratigraphical series and geochronological epoch with a precise global start date would drastically reduce the Anthropocene’s utility across disciplines. Instead, we propose the Anthropocene be defined as a geological event, thereby facilitating a robust geological definition linked with a scholarly framework more useful to and congruent with the many disciplines engaging with human-environment interactions. Unlike formal epochal definitions, geologi- cal events can recognize the spatial and temporal hetero- geneity and diverse social and environmental processes that interact to produce anthropogenic global environ- mental changes. Consequently, an Anthropocene Event would incorporate a far broader range of transformative human cultural practices and would be more readily applicable across academic fields than an Anthropocene Epoch, while still enabling a robust stratigraphic characterization.
