Anthropoceneとは 意味・読み方・使い方

語源

From a combination of anthropo- +‎ -cene modeled on Holocene, Pleistocene, and similar. First attested in the 1960s in the translations of Russian-language scientific articles, possibly with a different meaning. Supposedly coined independently in the 1980s by American biologist Eugene Stoermer and later popularized by Dutch atmospheric chemist Paul J. Crutzen in 2000.

固有名詞

the Anthropocene

1. (geology, formal, strictly) A proposed but rejected geological epoch, in which the effect of human activities on the global environment has disrupted the natural variability of the Holocene, ending the Holocene. (It was rejected as formal scientific nomenclature in 2024 owing to not meeting a bar for how a geological epoch is formally defined.) [from 1960s]

   Holonyms: Quaternary (current period), Age of Man (dated)

   Coordinate term: Holocene (as separate epoch)

     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.

   • 2020 April 9, Richard Horton, “Coronavirus is the greatest global science policy failure in a generation”, in The Guardian‎:

     We’re supposed to be living through the Anthropocene, an era where human activity has become the dominant influence on the environment. The idea of the Anthropocene conjures notions of human omnipotence.

   • 2024 March 22, Damian Carrington, “Geologists reject declaration of Anthropocene epoch”, in The Guardian‎, →ISSN:

     The guardians of the world’s official geological timescale have firmly rejected a proposal to declare an Anthropocene epoch, after an epic academic row.

2. (loosely, informal) The era of human impact on the environment, irrespective of its nomenclatural status as a geological event or epoch; especially, the era of large impact (i.e., on industrial and postindustrial scale).

   Holonyms: Holocene (current epoch) < Quaternary (current period), Age of Man (dated)

   Meronym: assholocene (informal)

使用する際の注意点

• The term has not been adopted in the official geological nomenclature. Defining the time of human impact on the environment as a geological event within the Holocene (rather than a separate epoch) has also been proposed. It is widely acknowledged that a loose and informal sense of the term lives on in popular usage, irrespective of nomenclatural status as a geological event or epoch.
