"Geologists Challenge the Notion of an 'Age of Humans'"

Geologists have rejected a proposal to define a new epoch, the Anthropocene, marking the start of the "Age of Humans" in the mid-20th century, citing concerns about rigidly defining human impacts within a specific timeframe. The working group behind the proposal, which emerged from 15 years of research, plans to continue advocating for the Anthropocene despite the rejection. While the debate over the Anthropocene's geologic definition continues, some geologists suggest defining it as a geologic event rather than an epoch, acknowledging the significant impact of human activities on Earth's history.

"Geologists Reject Anthropocene Epoch Declaration"

A panel of scientists has voted against officially declaring the start of the Anthropocene, a proposed new epoch of geologic time defined by humanity's impact on the planet. The decision means that, according to current geologic timelines, the Earth remains in the Holocene, which began 11,700 years ago. The proposed declaration would have significant implications for scientific terminology and understanding of human-induced changes to the planet for generations to come.

"Defining the Anthropocene: Crawford Lake and Nuclear Fallout as Markers of Human Impact on Earth"

A panel of scientists has chosen Crawford Lake in Ontario, Canada, to represent the start of the Anthropocene epoch, a proposed new chapter in Earth's history that marks significant human-induced changes to the planet. The lake was selected for its clear evidence of humankind's influence on the global geologic record, including changes in plutonium and radiocarbon from nuclear detonations, and fly ash from burning fossil fuels. The final ruling on the Anthropocene will determine the nomenclature used in academic studies and shape humanity's understanding of its impact on Earth. However, the process of ratification by geologists is still ongoing, and some members have resigned due to disagreements over the panel's approach.
