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.
There have been approximately 11 different ice ages that have occurred during the earthâs 4.6 billion years of existence. The last ice age was called âThe Great Ice Ageâ, and it occurred 11,000 years ago. During the âGreat Ice Ageâ over a third of the earth was covered in ice, and the air had less carbon dioxide in it.
