While the proposal to formally designate the Anthropocene as a distinct geological epoch has gained widespread interdisciplinary currency, stratigraphers remain sharply divided over its temporal boundaries and evidentiary criteria. Proponents of a mid-twentieth-century inception point—often termed the 'Great Acceleration'—argue that anthropogenic markers such as artificial radionuclides from thermonuclear testing and microplastic deposits provide an abrupt, globally synchronous signal requisite for establishing a Global Boundary Stratotype Section and Point (GSSP). However, this chronostratigraphic focus on a definitive mid-century horizon has drawn critique from environmental historians and archaeologists who contend that such criteria obscure millennia of cumulative human impact. Critics advocate instead for a diachronous framework, emphasizing that transformative processes—such as Neolithic agricultural land clearing and early industrialization—unfolded heterogeneously across geographic regions. Rather than viewing human influence through the lens of an instantaneous stratigraphic boundary, these scholars conceptualize the Anthropocene as an ongoing, trans-temporal modification of terrestrial systems. Consequently, the debate reflects a deeper epistemological tension within earth sciences: whether geological epochs must adhere strictly to synchronous physical markers in sediment cores, or whether they can accommodate complex, time-transgressive ecological transitions.
