Rethinking the Anthropocene: Not a time-transgressive event but a sudden rupture on the geologic time scale
The recent decision by the International Commission on Stratigraphy to reject the Anthropocene as an Epoch has reignited the debate on its definition. Some scholars have argued for interpreting the Anthropocene as an Event with no specific point of onset, but this argument has its shortcomings, including the fact that the term event has multiple connotations. This Viewpoint adds important insight to the ongoing debate by positing that (i) deliberations on the Anthropocene’s definition should not be confined to geological and historical viewpoints and must include ecological insights, and (ii) there is widespread evidence of anthropogenic reconfiguration of the planetary biosphere which translates to an accelerating sixth mass extinction as well as a conspicuous rise in the Human Appropriation of Net Primary Productivity (HANPP) at an unprecedented rate during the past few decades. When considered together with rapid anthropogenic climate change, these trends mark a major departure from previous trends on the geologic timescale, and they clearly show that the planetary biosphere has recently undergone a sudden and abrupt shift into a novel state, which cannot be adequately described by a temporally diffuse, gradual event; and must be conceptualized as a rupture—a geologically sudden major departure from prevalent trends; which in turn justifies the conceptualization of the Anthropocene as a separate chronostratigraphic unit. Understanding the catastrophic nature of the recent anthropogenic impact on the planetary biosphere is crucial for interpreting the Anthropocene and geologists must be cautious not to dilute its magnitude.

期刊介绍:
Anthropocene is an interdisciplinary journal that publishes peer-reviewed works addressing the nature, scale, and extent of interactions that people have with Earth processes and systems. The scope of the journal includes the significance of human activities in altering Earth’s landscapes, oceans, the atmosphere, cryosphere, and ecosystems over a range of time and space scales - from global phenomena over geologic eras to single isolated events - including the linkages, couplings, and feedbacks among physical, chemical, and biological components of Earth systems. The journal also addresses how such alterations can have profound effects on, and implications for, human society. As the scale and pace of human interactions with Earth systems have intensified in recent decades, understanding human-induced alterations in the past and present is critical to our ability to anticipate, mitigate, and adapt to changes in the future. The journal aims to provide a venue to focus research findings, discussions, and debates toward advancing predictive understanding of human interactions with Earth systems - one of the grand challenges of our time.
