OP, the things I have studied and read have led me to the same conclusion that you put so concisely in your post. I like how you referred to a "cover story". It is also a very lucrative cover story for a lot of people.
I lean toward the theory that the earth's magnetic field governs tectonic activity, and that changes in the magnetism affect underwater vulcanism; heat from volcanoes on the sea floor is the engine that drives climate change.
I read a lot of stuff about the ancients and the precession of the equinoxes before I read Robert Felix's "Not by Fire but by Ice" [

I think you put things very nicely in your original post.
thank you, I merely draw on the spirit which hears the earths voice to make all things known to us. Any credible geologist will tell you that the Valley of Giza where the great pyramids are located was inundated with water as little as 11,000 years ago. This indicates that once we have passed the galactic plane it may take somewhere around 2000 years before the earth starts correcting itself causing the waters to recede.
One ice-age does not make a pattern.
heading into another one 13,000 years later does
