What is Anthropocene epoch?
- Anthropocene epoch proposes a present geological interval marked by radical ecosystem changes due to human impact.
- Stormer and Crutzen coined “Anthropocene” in 2000, blending Greek roots for “man” and “new,” signifying a new epoch shaped by human influence on Earth’s systems.
- Phenomena linked to the proposed Anthropocene Epoch include global warming, sea-level rise, soil erosion, and environmental degradation.
Anthropocene Working Group (AWG)
- The Anthropocene Working Group (AWG) is an interdisciplinary research group dedicated to the study of the Anthropocene as a geological time unit.
- Established in 2009, the Anthropocene Working Group operates under the International Commission on Stratigraphy’s Subcommission on Quaternary Stratigraphy.
- The group determined in 2016 that the Anthropocene epoch began around 1950 — the start of the era of nuclear weapons tests, the geochemical traces of which can be found around the world.
- Researchers have evaluated 12 sites for crucial evidence supporting the proposal of the Anthropocene Epoch.
- The current warm period, identified as the Holocene, corresponds with the rapid proliferation, growth, and impacts of the human species worldwide.

Earth’s geological time scale
- The geologic time scale is the “calendar” for events in Earth history.
- Subdivision: It subdivides all time into named units of abstract time called—in descending order of duration— eons, eras, periods, epochs, and ages.
- Methodology: The enumeration of those geologic time units is based on stratigraphy, which is the correlation and classification of rock strata.
- Fossil markers:The fossil forms that occur in the rocks, however, provide the chief means of establishing a geologic time scale, with the timing of the emergence and disappearance of widespread species from the fossil record.
