how can the precession of the Earth’s axial spin (“precession of the equinox”) drive the Earth’s climate into a state of major glaciation, or drive it out of that state into the warmer climate of the interglacial.
The earth's axis is tilted so that we experience winter when our hemisphere is tiled away from the sun, and summer when tilted towards the sun. But I don't think the axis had to do with the ice age...it was more of a cyclicle phenomenon of our clima
I think the reason certain Christians and Jews believed the Mayan Doomsday date would be the End of the World is because one of the few actual prophecies the Mayans wrote about 12-21-2012 was that a “God-Man will return to Earth. “God-Man” was obviously interpreted by Jews and Christians to mean......

The moon's axial tilt from the ecliptic is 1.5424 degrees, causing a circle ~ 46.7 km radius at the pole to be in shadow for the lunar winter, and in light for the lunar summer.. analogous to seasons on the earth. Like...

it talks about the elliptical orbit. I'm confused by it, the length of it really and the term. Here's the quote from the
These are all variations in the shape, eccentricity and orientation of the Earth's orbit, as well as the tilt of the Earth's axis. Various combinations of the different periods of these variations have been proposed as the driving force behind climate
