When were the Ice Ages?
The Ice Ages ended about ten thousand years ago after lasting
about two millions years. At its greatest extent the ice covered nearly 30% of
the land surface of the world, compared with about 10% today. The great glaciers
reached as far south in America as present day Nebraska and Kansas an extended
over the whole of northern Europe down to align linking London and Berlin. But
there were a number of intervals when temperatures rose and the ice retreated
temporarily to its present limit during this warm periods, which totalled
several hundred years, the liberated areas where re-populated. The climate is
believed to have been warmer at times than it is today.
