Document Summary
Eon era period epoch age. Period in time that starts with a geological even big changes. Changes in biodiversity, fossils, climate, etc changes last a long time. Holocene the 12,000 years of stable climate since the last ice age during which all human civilisation developed. It"s the transition from the last glacial phase into an interval of warming accompanied by sea level rise. More carbon dioxide and oxygen in the atmosphere. The holocene represents the most recent interglacial interval of the quaternary period. The holocene epoch is divided into three component sub-epochs, using climatic changes to guide the position of their bases: The beginning of the anthropocene is not clearly defined. The anthropocene could be said to have started in the late eighteenth century, when analyses of air trapped in polar ice showed the beginning of growing global concentrations of carbon dioxide and methane.
