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 , and mean annual temperatures across the Northern Hemisphere declined by 0.6 °C ( ...
Did humans survive the last ice age?
During the past 200,000 years, homo sapiens have survived two ice ages. ... While this fact shows humans have withstood extreme temperature changes in the past, humans have never seen anything like what is occurring now.

What caused the last ice age to end?
When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age. When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt , and the ice age ends.

Are we in the ice age?
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.
