(DAILY MAIL) — 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.’
