Tell Me, About The End of Ice Age?

As the very name suggests and most people think that the ice Age is something that happened long ago and there is no sign of which left. In actuality, this is not the case. According to Geologists we are just reaching the end of the Ice Age. The living in Greenland, are actually living still in the Ice Age, as far they are concerned.

People living in central North America, as back as 25,000 years must have seen ice and snow year-round. A great wall of ice stretched from coast to coast. The ice extended to vast distances towards the north, of which no end was in sight. This was the latest Ice Age. Entire Canada, much of the United States and most parts of northwestern Europe were ice clad. The thickness of this sheet of ice was thousands of meters.

This did not mean that it was always icy cold. The temperature was only about 10 degrees lower than it is now in the Northern United States. What caused the Ice Age was that the summers were very cool. There is not adequate heat in summers to melt snow and ice of winters. The piling up of snow and ice continued until it covered the entire northern area.

The Ice Age actually extended over four periods. During every period ice formed successively and advanced, and then melted back towards the North Pole. It happened four times. The cold spells are called “glaciations” and the warm periods are called “interglacial” periods.

Believably, the first period of ice came in North America about 2,000,000 years ago, the second about 1,250,000 years ago, the third about 500,000 years ago, and the last about 100,000 years ago.

The last Ice Age did not melt everywhere uniformly. The ice that reached Wisconsin started melting about 40,000 years ago. The ice covering New England melted about 28,000 years ago. Minnesota was snow until about 15,000 years back.

In Europe, Germany got cleaved of ice about 17,000 years ago, while Sweden was under snow until about 13,000 years back.
