Anthropocene

Pieces of plastic waste fouling a beach in Hawaii, USA. The profound impact that the activities of human beings are having on the environment have led to the word Anthropocene being used to describe the current age.

Portmanteau of anthropo- (“prefix meaning ‘man’”) + words like Holocene, Pleistocene, etc.;[1] supposedly coined in the 1980s by American biologist Eugene F. Stoermer (1934–2012) and popularized by Dutch atmospheric chemist Paul J. Crutzen (born 1933) in 2000,[2] but already in use in the 1960s, possibly with a different meaning: see the quotations.

   Coordinate term: Holocene (current epoch)

   Hypernym: Quaternary (current period)

     The tempo of evolution in South American hamsters was very rapid – in the course of the Pliocene and Anthropocene 40 genera were formed here, at which time a series of them attained the level of tribe and subtribe (Oxymycteri, Phyllotiini, Ichthyomyini).

     The above palynologic data indicate that the evolutionary history of vegetation in the upper reaches of the Indigirka during the Holocene was much more complex than has been thought and than is reflected in the existing stratigraphic maps of the Anthropocene of the Northeast USSR […].

     Considering these and many other major and still growing impacts of human activities on earth and atmosphere, and at all, including global, scales, it seems to us more than appropriate to emphasize the central role of mankind in geology and ecology by proposing to use the term "anthropocene" for the current geological epoch.

     Phoenix [in Arizona] and Lubbock [in Texas] are both caught in severe drought, and it is going to get much worse. We may see many such [dust] storms in the decades ahead, along with species extinctions, radical disturbance of ecosystems, and intensified social conflict over land and water. Welcome to the Anthropocene, the epoch when humans have become a major geological and climatic force.

     Plastics are energy-rich substances, which is why many of them burn so readily. Any organism that could unlock and use that energy would do well in the Anthropocene. Terrestrial bacteria and fungi which can manage this trick are already familiar to experts in the field.

     People are changing Earth so much, warming and polluting it, that many scientists are turning to a new way to describe the time we live in. They're calling it the Anthropocene — the age of humans. Though most non-experts don't realize it, science calls the past 12,000 years the Holocene, Greek for "entirely recent." But the way humans and their industries are altering the planet, especially its climate, has caused an increasing number of scientists to use the word Anthropocene to better describe when and where we are.

As of June 2019, the term has not been adopted in the official geological nomenclature.
