Where did the Little Ice Age occur?
Little Ice Age (LIA), climate interval that occurred from the early 14th century through the mid-19th century, when mountain glaciers expanded at several locations,
including the European Alps, New Zealand, Alaska, and the southern Andes

ice sheets melt
, and the ice age ends.

Striking during the time period known as the Pleistocene Epoch, this ice age started about 2.6 million years ago and lasted until roughly 11,000 years ago. Like all the others, the most recent ice age brought a series of glacial advances and retreats. In fact,
we are technically still in an ice age.
