OOPS!!!

Natural tilts in earth’s axis cause ice ages, says Harvard geophysicist
By Robert


“The idea that slight shifts in Earth’s axis might have been enough to trigger the ice ages is a century old,” says this article in the Daily Mail.

“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.”

In a paper published in the journal Nature, Huybers points out that the way in which the Earth’s axis of rotation spins controls our climate. The process involves two cycles, one lasting about 10,000 years, the other roughly 40,000 years.

When the two cycles align ‘correctly’, the glaciers retreat rapidly, says Huybers. At the other extreme, glaciers advance...
