" In order for ice masses to have been formed, increased precipitation must have
taken place. This requires an increased amount of water vapor in the atmosphere, which is
the result of increased evaporation from the surface of oceans; but this could be caused by
heat only. A number of scientists pointed out this fact, and even calculated that in order to
produce a sheet of ice as large as that of the Ice Age, the surface of all the oceans must have
evaporated to a depth of many feet. Such an evaporation of oceans followed by a quick
process of freezing, even in moderate latitudes, would have produced the ice ages. The
problem is: What could have caused the evaporation and immediately subsequent freezing?
As the cause of such quick alternation of heating and freezing of large parts of the globe is
not apparent, it is conceded that "at present the cause of excessive ice-making on the lands
remains a baffling mystery, a major question for the future reader of earth's riddles."
Not only are the causes of the appearance and later disappearance of the glacial sheet
unknown, but the geographical shape of the area covered by ice is also a problem. Why did
the glacial sheet, in the southern hemisphere, move from the tropical regions of Africa
toward the south polar region and not in the opposite direction, and, similarly, why, in the
northern hemisphere, did the ice move in India from the equator toward the Himalaya
mountains and the higher latitudes? Why did the glaciers of the Ice Age cover the greater
part of North America and Europe, while the north of Asia remained free? In America the
plateau of ice stretched up to latitude 40° and even passed across this line; in Europe it
reached latitude 50°; while northeastern Siberia, above the polar circle, even above latitude
75°, was not covered with this perennial ice. All hypotheses regarding increased and
diminished insolation due to solar alterations or the changing temperature of the cosmic
space, and other similar hypotheses, cannot avoid being confronted with this problem.
Glaciers are formed in the regions of eternal snow; for this reason they remain on the slopes
of the high mountains. The north of Siberia is the coldest place in the world. Why did not
the Ice Age touch this region, whereas it visited the basin of the Mississippi and all Africa
south of the equator? No satisfactory solution to this question has been proposed."
The extinction of the mammoths occurred simultaneously with the end of the last Ice Age.
