The Last Ice Age

Posted by Kyle Brookings on Wednesday, January 4, 2017

The last Ice Age occurred from 110,000 to 12,000 years ago.

Over the past few million years the glacial-interglacial cycle has been "paced" by periodic variations in the Earth's orbit via Milankovitch cycles which are thus the "cause" of ice ages.

There were humans on Earth at that time however they were confined to Africa.

 Near the end of the event, humans spread into Eurasia and Australia. 

Canada was nearly completely covered by ice, as well as the northern part of the United States, both blanketed by the huge Laurentide ice sheet. Alaska remained mostly ice free due to arid climate conditions. 

The last glaciation centered on the huge ice sheets of North America and Eurasia. Considerable areas in the Alps, the Himalaya and the Andes were ice-covered, and Antarctica remained glaciated.

Around 11,700 years ago marked the beginning of the Holocene geological epoch, which includes the Holocene glacial retreat.
