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.
An ice age is a period of colder global temperatures that features recurring glacial expansion across the Earthâs surface. Capable of lasting hundreds of millions of years, these periods are interspersed with regular warmer interglacial intervals in which at least one major ice sheet is present.
