Our current epoch, the Holocene, began roughly 11,700 years ago, following the Pleistocene which started 2.6 million years ago. Together they form the Quaternary period, marked by dramatic glacial-interglacial swings. The Eemian (~116,000-129,000 years ago) was even warmer than today with seas 20+ feet higher.
Pleistocene began 2.6 million years ago; Holocene started ~11,600 years ago
