The Ice Ages began 2.4 million years ago and lasted until 11,500 years ago. During this time, the earth's 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.
Are we currently in an 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.
What happens during an ice age?
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet.
What was living during the ice age?
What Types of Mammals Lived during the Ice Ages? During the Ice Ages, there were mammals that are very familiar to us like deer, pack rats, and ground squirrels. But there were also unusual mammals, most of them very large, that are now extinct.
What is the ice age period called?
The Pleistocene Epoch is typically defined as the time period that began about 2.6 million years ago and lasted until about 11,700 years ago, according to Britannica. The most recent Ice Age occurred then, as glaciers covered huge parts of the planet Earth.

What triggers an ice age?
The variation of sunlight reaching Earth is one cause of ice ages. ... 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.
What would happen if Antarctica melted?
If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. ... Ice actually flows down valleys like rivers of water .
How did humans survive the last ice age?
Fagan says there's strong evidence that ice age humans made extensive modifications to weatherproof their rock shelters. They draped large hides from the overhangs to protect themselves from piercing winds, and built internal tent-like structures made of wooden poles covered with sewn hides.
