Evidence Mounting for Beginning of Anthropocene Epoch

Many scientists argue that the latest geological epoch of Earth’s history – coined the Anthropocene Epoch – has already begun thanks to the actions of humanity. While the claim is met with some controversy, new evidence is mounting that the new epoch has indeed begun, according to a new research report published by a group of international scientists.

The influence humanity has had on the planet in regards to the geological record is undeniable according to the scientists. The now widespread accumulation of nuclear fallout, fly ash, plastic, concrete and aluminum in the ground is indicative of the beginning of the Anthropocene and can be traced back to the middle of the twentieth century, the research results say. When combined with other persistent environmental changes brought about by man, such as higher greenhouse gas emissions, the scientists say that the 11,700-year Holocene Epoch – the geological era that began with the end of the last Ice Age – has now come to an end.

Humans have long been an influence on the environment around them, according to the British Geological Survey’s Dr. Colin Waters. However, unlike the gradual changes that characterized the Holocene, such as incremental domestication of the land to heighten food production and the slow but steady proliferation of urban settlement, the Anthropocene is differentiated by how rapidly new materials have begun to spread across the globe, the scientist remarked. Plastics, concrete, and other man-made materials have all begun to leave their mark in the sediment record, and study co-author Jan Zalasiewicz from the University of Leicester stated in a press release that all this, plus other evidence collected by the research team such as the radionuclides accumulating in the soil from the numerous international atomic bomb tests from 1945 through the 1980s, provides “an underlying reality” to the concept that the Anthropocene has not only begun but is in full swing.
