Paragraph 2
The scientists said
ice in the North and South Poles will push back the ice age. Researcher Professor Stephen Barker studied how
ice ages happened. He looked at one million years of climate
. He found relationships between
in the Earth's
, global temperatures, and the
of Antarctica and the Arctic. When the
of ice was stable, ice ages happened at
intervals. However, Professor Barker said less ice means a longer
between ice ages. He said Earth's climate is "an interconnected
of complex processes".
