Study of available geological evidence indicates that it is
more common for our planet to be in an ice age than it is to
be in it's present state. The duration of a common ice age
is approximately one hundred thousand years, while
intermittent periods, such as that of our own time, tend to
last about fifteen thousand years. What causes an ice age?
During cool summers in the northern hemisphere, snow at high
altitudes fails to melt. This build up forms thick layers of
ice. Because these layers of ice reflect the suns rays,
subsequent summers will be colder as the ice build continues.
