"So–called polar
wandering (in which the earth's axis actually remains fixed
in its direction in space while the earth's matter moves
around it – like a toffee-apple on a stick) may have
brought on the ice ages by reducing the earth's energy
intake: by changing dark, heat–absorbent areas of the land
into snow–covered, reflective areas. As long as the poles
were at sea in the Atlantic and Pacific, their ice–packs
must have been held in check by the moderating warmth and
dispersing currents of the ocean. But when Antarctica,
Canada, Siberia and Greenland turned frosty white, the
earth must have taken in less of the sun's heat every year,
and gradually the whole earth, including the heat reservoir
of the oceans, must have grown colder."
