Yes. An ice age is a period over tens of millions of years where
the Earth is cold enough to produce permanent ice sheets. Since
permanent ice sheets currently exist in Greenland and
Antarctica, it qualifies the current age to be an ice age. This
current ice age began 30 million years ago. Within an ice age
there are warm periods referred to as "interglacial" and cold
periods referred to as "glacial." We are in an interglacial
period right now. Factor such as changes in the Earth's axis and
orbit; tectonic plate shifting; volcanic matter explosions or
meteoric impacts; and an increase in carbon dioxide emission
from industrial pollution all contribute to changes in the
Earth's climate. How is an iceberg formed? Answered by Animal
