What is the Holocene era?
The Holocene is the name given to the last 11,700 years* of the Earth’s history — the time since the end of the last major glacial epoch, or “ice age.” Since then, there have been small-scale climate shifts — notably the “Little Ice Age” between about 1200 and 1700 A.D. — but in general, the Holocene has been a …

Are we in the Holocene period?
According to the International Union of Geological Sciences (IUGS), the professional organization in charge of defining Earth’s time scale, we are officially in the Holocene (“entirely recent”) epoch, which began 11,700 years ago after the last major ice age.

Some would assign it to the start of agriculture 11,000 years ago, while others tie it to the advent of the nuclear era in 1945, but most recognise the Anthropocene as beginning with the industrial revolution (1780s-1830s).
