The Ice Ages began 2.4 million years ago and lasted until 11,500 years ago. During this time, the earthâs climate repeatedly changed between very cold periods, during which glaciers covered large parts of the world (see map below), and very warm periods during which many of the glaciers melted.
Therefore, any of several dates ranging over 400 years may indicate the beginning of the Little Ice Age: 1  1250 for when Atlantic pack ice began to grow; cold period possibly triggered or enhanced by the massive eruption of Samalas volcano in 1257. 2  1275 to 1300 based on the radiocarbon dating of plants killed by glaciation.
