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.

We’ll delve into the science of solar cycles, how solar radiation affects the atmosphere, and why this theory challenges the traditional Milankovitch explanation.

The Milankovitch cycles are the driving force behind ice ages, climate shifts and habitability of planets.

The Milankovitch Cycles consider the wobble of Earth's axis and change in orbit shape in relation to climate change both past and present.

This posting discusses the role of the Milankovitch Cycles in initating glaical/interglacial periods. It also discusses the role of sunspots in short term climate change.

Milankovitch cycles and solar inertial motion can't explain modern global warming Milankovitch cycles are long-term changes in the orbit and orientation of the Earth as it moves around the sun.

For Baez, any serious study of global climate change has to take the Milankovitch cycles into account along with anthropogenic causes of warming.
