What if Earth tilted?

Imagine that Earth tilted to a significant extent. This is not impossible. It is also not improbable. It can happen. After all, it is only a small rock with a molten interior and a somewhat hard but thin surface. It rockets along its trajectory around the sun, the life-giver for the puny humans camped a little precariously on its surface, and who are accompanied by the life-support systems provided by Nature. It spins, wobbles, and (possibly) responds to the powerful forces buffeting it in space. These could range from solar winds and all manner of radiation, as well as objects tiny to huge.

So, did Earth tilt significantly about 13,000 years ago? Did it tilt enough to tip some of the then occupants into space? If they had been dislodged, would that have occurred suddenly? Would the involuntary exiles then have joined the almighty swarm of debris in nearby space as unwieldy clumps of soon-to-be-deconstructed stardust? This is, of course, not a probable scenario; our occupancy of Earth is probably comparable to the occupancy by bacteria of the human body – not even noticeable, but potentially totally destructive!

The recent slight tilt of Earth, which I detected by watching the sun rise over the sea, and continue to experience, does not seem to have been noticed by the media. Why? Is periodic tilting not worth mentioning? Or are the horses not to be frightened? As I observed, the sun began to rise further and further south progressively for a few years. There is no evidence of a further, or reverse, shift. Is the tilting I observed responsible for the melting of the Arctic? It was in the right direction. The North Pole is now closer to the sun.

As it wobbles through space, the sun can obviously tilt this way or that, or glide closer to, or further from, the sun in the manner of a gliding ballroom dancer (but not a flamenco dancer). Yet, something spoiled this dance 13,000 years ago – so say many, many folk memories, and many scientific researchers.

What happened, and what was the cause?
