Paragraph 2
The scientists said melting
in the North and South Poles will push back the
ice age. Lead researcher Professor Stephen Barker studied what caused
ice ages to happen. His team looked at
one million years of climate data. They found that there was a
between changes in the Earth's
, global temperatures, and the size of Antarctica and the Arctic. When the
of ice on the continental ice sheets was stable, ice ages happened at regular
. However, Professor Barker said less ice means a longer gap between ice ages. He added: "Earth's climate is an interconnected
of complex processes, all acting together to produce the
we observe."
