Ice Planet - Breathtaking Footage Of Earth’s Wintry Side

About the Glacial periods of our Earth.
Over the past 3 billion years, the Earth has undergone approximately 5 significant ice ages.
The first one - Cenozoic Ice Age began 34 million years ago. The latest one - the Quaternary glaciation, which is in progress since 2.5 million years ago. Within the major ice ages there are the periods of severe and mild glacial conditions known as the glacial and inter-glacial periods. The Earth is currently in such an inter-glacial period of the Quaternary glaciation - the Holocene epoch.
The most recent glacial period - Quaternary glaciation, have ended between about 120,000 and 11,700 years ago.

Interesting facts:
The most recent glacial period - Quaternary glaciation, have ended between about 120,000 and 11,700 years ago.
Humans developed significantly during the most recent glaciation period, emerging as the dominant 'land animal' afterward as such large species as the mammoth, giant ground sloths, the mastodons, saber-toothed cats etc. which reigned during the glacial period went extinct by its end.
Humans were able to adapt to the harsh climate by developing such tools as the bone needle to sew warm clothing.
By the start of the mild Holocene epoch, our ancestors were in position to take advantage of the warm conditions by developing domestication techniques and agricultural.
An Ice age causes changes to the Earth’s landscape. Glaciers reshaping the surface by displacing soil and rocks, by eroding hills during their unstoppable movement.
Humans have recorded about 5 large-scale ice ages throughout the Earth’s history:
The Huronian (approx. 2.4 billion years ago),
The Cryogenian (approx. 850 - 635 million years ago),
The Andean-Saharan (approx. 460 - 430 million years ago),
The Karoo (approx. 360 -260 million years ago),
The Quaternary (approx. 2.6 million years ago - present).
Roughly a dozen major Glaciations have occurred over the past 1 million years.
The largest Glaciation peaked approx. 650, 000 years ago and lasted for 50, 000 years.
The most recent Glaciation period, known as the 'Ice Age', reached its peak conditions some 18,000 years ago, before passing the baton to the Interglacial Holocene epoch 11,700 years ago.
