Holocene

The Holocene is the present geological epoch. It started around 11,000 years ago after the last ice age. We are now in a relatively warm climate in Earth's history.
This is the second epoch of the Quaternary and the seventh of the Cainozoic.
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). 
The warm period was followed by a gradual decline until about two millennia ago.
More details.
The Holocene is also called the Recent epoch. It is the second stage in the Quaternary period.
The Holocene marks the end of the previous series of ice ages in the Pleistocene. About 11,700 years ago the temperatures rose quickly from the previous level.
During the early Holocene, there were many extinctions amongst larger mammals. This is because of human hunting and climate change.
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.
