Holocene facts for kids
The Holocene is the present geological epoch. It is the second epoch of the Quaternary and the seventh of the Cainozoic. It started around 11,000 years ago after the last ice age. We are currently going through a non-ice age warm stage in Earth's history.
Holocene climatic optimum
The Holocene climatic optimum (HCO) was a warm period from about 9,000 to 5,000 years BP. The interesting thing about this is, despite recent global warming, we are still below this warm period (see diagram).
This warm period was followed by a gradual decline until about two millennia ago.
The Holocene is also called the Recent epoch. It is the second stage in the Quaternary period.
At this time the Bering bridge connecting Russia and Alaska melted. Also the land bridge between China and Japan melted (starting the Jōmon period), as well as many land bridges between islands in Southeast Asia.
