Holocene



:)

from Wikipedia:
The Holocene (pronunciation: /ˈhɒləˌsiːn, ˈhoʊ-/) is the geological epoch that began after the Pleistocene at approximately 9,700 BCE and continues to the present. The term "Recent" (usually capitalised) has often been used as an exact synonym of "Holocene", although this usage is discouraged in 21st-century work. The Holocene is part of the Quaternary period. Its name comes from the Greek words ὅλος (holos, whole or entire) and καινός (kainos, new), meaning "entirely recent". It has been identified with the current warm period, known as MIS 1, and can be considered an interglacial in the current ice age based on that evidence.

The Holocene also encompasses the growth and impacts of the human species worldwide, including all its written history, development of major civilizations, and overall significant transition toward urban living in the present. Human impacts on modern-era Earth and its ecosystems may be considered of global significance for future evolution of living species, including approximately synchronous lithospheric evidence, or more recently atmospheric evidence of human impacts. Given these, a new term, Anthropocene, is specifically proposed and used informally only for the very latest part of modern history involving significant human impact.
