Anthropocene Epoch Proposal
In August 2016, the Anthropocene Working Group recommended officially designating the Anthropocene as a new geological epoch defined by human impact on Earth’s geology and ecosystems—marking the moment Homo sapiens became a planetary-scale geological force rivaling ice ages and asteroid impacts.
The proposal suggested the Anthropocene began around 1950, marked by radioactive isotopes from nuclear testing, plastic pollution layers, concrete ubiquity, chicken bones in strata (domesticated chickens now outnumber wild birds 10:1), and CO2 concentrations unprecedented in 800,000 years. These markers would persist in geological records for millions of years.
The announcement generated intense academic and popular debate. Geologists questioned whether human impacts meet formal criteria for epoch designation (requiring global synchronous markers in rock records). Historians argued the Anthropocene should begin with agriculture (10,000 BC), colonialism (1492), or the Industrial Revolution (1760s) rather than mid-20th century.
The term, coined by ecologist Eugene Stoermer and popularized by Nobel laureate Paul Crutzen in 2000, gained mainstream recognition through the 2016 proposal. It generated 35+ million social media impressions as environmentalists embraced it as framing for climate action, while critics noted it obscured unequal responsibility (wealthy nations/corporations driving impacts more than subsistence farmers).
By 2023, the International Commission on Stratigraphy continued debating formal ratification. Regardless of official status, “Anthropocene” entered common usage describing humanity’s planetary dominance—mass extinctions, altered nitrogen and carbon cycles, microplastic contamination, and climate disruption that will define Earth’s geological record long after human civilization ends.
