I was thinking the same thing. The Mayans had an incredible knowledge of astronomy as evidenced by numerous engineered wonders aligned with solar movement. The disinformation spread about the 12/21/2012 "end times" was just a distraction to discredit them. The obliquity of the ecliptic or processional code is encoded in ancient megaliths around the globe. It has to do with a wobble in the earths rotation (much like a top) and results in a shift or movement from our point of view. Every 72 years the stars will shift 1 degree over 2160 years and a constellation is replaced now moving into the age of Aquarius.
Thanks for this update but I must say without having viewed his previous videos showing historical records backing his theory I would say the climate has a lot of anomalies.
Facts related to the ancients knowledge of the Earths very complex movement is astonishing and tremendously under appreciated and largely unknown . The knowledge and skill goes against the main stream view that has been taught of ancient man abilities.

Birkeland currents connect the stars to each other. It looks kind of random but also looks like a neural network, much like in our brain, connections to nerves, etc.
