Anthropocene Epoch Debate: Earth's Turning Point



  Mar 08, 2024

The Debate Over Declaring the Anthropocene Epoch



The proposal to declare the Anthropocene as an official geological epoch has sparked a significant dispute within the scientific community. This epoch is intended to recognize the profound and irreversible changes humans have made to the Earth, marking the end of the Holocene epoch, which lasted for 11,700 years of stable global environment crucial for human civilization’s development.

Key Points of Contention:

1. Start Date of the Anthropocene: The proposal pinpointed 1952 as the starting point of the Anthropocene, chosen due to the global fallout of plutonium from nuclear weapons tests. However, opponents argue that human impact on the planet started much earlier, with activities like farming, and cannot be limited to a specific date.

2. Geographical Marker: The proposal also required a specific location to symbolize this change, choosing sediments in a sinkhole lake in Canada. This aspect is a standard requirement for defining a new geological epoch.

3. Vote and Controversy: A vote by the Subcommission on Quaternary Stratigraphy (SQS) in February appeared to reject the proposal, with a 12 to 4 vote. However, this vote’s validity has been questioned, with claims it violated committee rules, leading to a call for an inquiry and possible annulment of the vote.

4. Future of the Anthropocene Proposal: Despite the current setbacks, the concept of the Anthropocene is already widely accepted to describe humanity’s impact on the planet. There’s an ongoing discussion on whether to classify the Anthropocene as a geological “event” instead, which does not require formal committee approval.

5. Scientific Backing: The Anthropocene Working Group, which developed the proposal, stands firmly behind their findings, emphasizing that the Earth system now clearly lies outside the stable conditions of the Holocene, citing evidence such as anthropogenic radionuclides, microplastics, fly ash, and pesticide residues.

This debate highlights the complexities of formally recognizing humanity’s impact on the Earth within the geological timescale. It underscores the significance of scientific processes and the need for consensus in making such determinations, reflecting the broader challenge of addressing human-induced environmental changes.
