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.
During the present ice age, glaciers have advanced and retreated over 20 times, often blanketing North America with ice. Our climate today is actually a warm interval between these many periods of glaciation. The most recent period of glaciation, which many people think of as the Ice Age, was at its height approximately 20,000 years ago.
