Labels also have special number codes, which represent the following: 1  0 = means minimal hazard. 2  1 = means slight hazard. 3  2 = means moderate hazard. 4  3 = means serious hazard. 5  4 = means severe hazard.
A good way to summarize the paper by Snelling and Matthews is by presenting the timeline given in the article and accompanying poster: AiG Ice Age Timeline. 1  2350 B.C.âNoahs flood. 2  2350 to 2250 B.C.âAntarctica becomes covered by forests, then gets covered by its ice cap.  2250 to 2000 B.C.âIce age on the rest of Earth.
The last Ice Age, known as the Pleistocene Epoch, began almost 1.8 million years ago and lasted until approximately 11,700 years ago. During this time, massive glaciers covered most of the surface of the Earth. There have been four known Ice Ages on Earth in the 4.6 billion years that the planet has existed. It is very possible that there were many more that occurred that are undocumented from before the advent of mankind, about 2.3 million years ago.
