Natural tilts in earth's axis cause ice ages......
The idea that slight shifts in Earth's axis might have been enough to trigger the ice ages is a century old.

But a Harvard earth sciences Professor Peter Huybers has finally proved it, using computer models to test competing ideas - and finding that earth's tilting axis is the only one that works.

The finding could have profound implications for our understanding of our planet's climate - and could, its author says, be crucial to 'predicting long-term changes in future climate.'

Two 'cycles' in the way Earth's axis spins have an effect on the cycle - one lasting 10,000 years and one lasting roughly 40,000 years.

When they align correctly, ice melts. At the other extreme, glaciers advance.

More likely the Earths orbit goes from a circular orbit to an elliptical orbit.
