The Earth's Shifting Crust by Charles Hapgood - wire of information

Ill : ANCIENT
CLIMATES
In the last chapter it was argued that the ice ages can be
explained only by the assumption of frequent displacements
of the earth's crust. The ice ages, however, represent only one
side of the problem. If they are instances of extremely cold
climates distributed in an unexplained manner on the earth's
surface, there were also warm climates whose distribution is
equally unexplained.
In connection with these warm climates in the present
polar regions, there arises a contradiction of an especially
character. On the one hand there is evidence that the
glaring
distribution of plants and animals in the past did not, as a
rule, follow the present arrangements of the climatic zones.
On the other hand, the trend of the new evidence is to show
that climatic zones have always been about as clearly dis-
tinguished by temperature differences as they are today. This
is in flat contradiction to the assumption, still widely held,
that the earth, during most of geological history,
did not
possess clearly demarcated climatic zones. We are forced to
conclude that, since many ancient plants and animals were
not distributed according to the present climatic zones, the
zones themselves have changed position on the earth's surface.
This requires, as we have seen, that the surface shall have
changed position relative to the axis of rotation. We shall
now examine the evidence that supports this conclusion.
/. Ages of Bloom in Antarctica

10,000 years ago, a large part of Antarctica may have been
ice-free. If this interpretation of the marine cores from the
Ross Sea is questioned by the conservative-minded, there
