For years, the term “Anthropocene” has been used to informally describe the human era on Earth. But new evidence suggests there’s nothing informal about it. We’re a true force of nature — and there’s good reason to believe we’ve sparked a new and unprecedented geological epoch.
A team of international geoscientists say the time has come for us to formally recognize the Anthropocene as a new epoch, one as significant as previous geological eras like the Holocene and Pleistocene. According to the new study, which appears in the latest issue of Science, it began sometime around the midpoint of the 20th century, and is fueled by a number of unquestionably human influences — including elevated greenhouse gas levels and the global proliferation of invasive species, along with the spread of materials such as aluminium, concrete, fly ash, and even fallout from nuclear testing.
