Hall said that the traditional explanation — and short answer — for why ice ages begin and end is a series of eccentricities and wobbles in the planet's orbit known as the Milankovitch cycles. Named after Serbian scientist Milutin Milankovitch, these cycles describe patterns in Earth's orbit and axial tilt. Over time, our planet's orbit around the sun alternates from being more circular to more egg-shaped. At the same time, our planet's axis tends to both tilt and wobble.
Milankovitch found that these factors combine at regular intervals to cause land at 65 degrees north latitude (a parallel that runs through Canada, Alaska and parts of Eurasia) to become warmer than normal and theorized that this warming and then subsequent cooling of the Northern Hemisphere explained the planet's cycle of ice ages — or glacials — and warmer periods — or interglacials.
"Quite simply, we can say that ice ages line up with these Milankovitch oscillations," Hall said. "But we don't know exactly why."
