Geologists are well known for separating the geologic time scale into many time units. The most recent time division, the Holocene, has now lasted about 11,700 years, during which time the climate has been fairly stable.

The name given to this new, human-caused epoch is the Anthropocene. The Anthropocene was most recently discussed last week at a Geological Society conference in London .
