The Meghalayan Age represents a recent geological chapter identified by the International Union of Geological Sciences (IUGS) in July 2018. Initiated 4,250 years ago, this age persists today, characterized by a mega-drought that led to the downfall of numerous civilizations around 2,250 years BCE.
The Anthropocene Epoch is a suggested geological stage recognizing the substantial human impact on Earth. Over recent years, a growing number of scientists have embraced the notion that we have entered this entirely new geological era.
While the Meghalayan Age delineates the "late Holocene" extending to the current era, it does not account for human influence on the environment. Conversely, the Anthropocene Epoch distinctly acknowledges such human impact as defining a new geological phase.
The discussion between these two geological phases stems from varying views on human environmental impact. Some scientists argue that human influence is profound enough to justify a new phase, the Anthropocene Epoch, while others maintain that we still reside in the Holocene Epoch, specifically within the Meghalayan Age.
Determining a new geological age or epoch holds considerable influence, especially amid escalating environmental changes and degradation. Such definitions can impact philosophical, social, economic, and political landscapes, shaping humanity's narrative and understanding of its environmental role.
To address the ongoing debate, a rational and comprehensive examination of geological time divisions is proposed. Establishing a new, multi-disciplinary IUGS commission dedicated to classifying and defining the current geological era could encourage consensus across scientific disciplines.
