The Anthropocene: From Global Change to Planetary Stewardship
The Anthropocene is a reminder that the Holocene, during which complex human societies have developed, has been a stable, accommodating environment and is the only state of the Earth System that the authors know for sure can support contemporary society.
The Anthropocene is functionally and stratigraphically distinct from the Holocene
C climatic, biological, and geochemical signatures of human activity in sediments and ice cores, Combined with deposits of new materials and radionuclides, as well as human-caused modification of sedimentary processes, the Anthropocene stands alone stratigraphically as a new epoch beginning sometime in the mid–20th century.

The Pliocene Epoch, 5.33–2.58 million years ago (Ma), was a generally warmer and wetter interval with atmospheric CO2-concentrations at or slightly above modern levels. This paper provides an…
Are we now living in the Anthropocene
The term Anthropocene, proposed and increasingly employed to denote the current interval of anthropogenic global environmental change, may be discussed on stratigraphic grounds. A case can be made…

The Anthropocene, an informal term used to signal the impact of collective human activity on biological, physical and chemical processes on the Earth system, is assessed using stratigraphic criteria and includes geologically novel aspects and geologically will have permanent effects.
The geological cycle of plastics and their use as a stratigraphic indicator of the Anthropocene
The rise of plastics since the mid-20th century, both as a material element of modern life and as a growing environmental pollutant, has been widely described. Their distribution in both the…
When did the Anthropocene begin? A mid-twentieth century boundary level is stratigraphically optimal
Abstract We evaluate the boundary of the Anthropocene geological time interval as an epoch, since it is useful to have a consistent temporal definition for this increasingly used unit, whether the…
