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.
Ice Ages. Our current climate regime -â a regime weâve had for the past ~2 million years â- is characterized by long periods of ice ages and shorter warm periods. The last ice age ended about 12,000 years ago, and since then weâve been in a warm period. Some argue that global warming is no concern, since the Earth will naturally switch back to an ice age. This is very likely to be true: an ice age is almost certainly in our planetâs future. But itâs a question of when. Our current concerns about climate change focus on the coming decades to the next century â- the time period relevant to our childrenâs and grandchildrenâs experience.
