Planetary rotation, geomagnetic poles & global warming
SDAI-Tech1 — (archived)

Yes, I know it's all pretty much WAG speculation.

I've read about the finding for seasonal variations in the fossilized records of Earth's history. Most is fairly convincing, but leaves the door wide open for more data and research techniques regarding the intensities of the seasons, and their timetables in the long, long ago.

In my mind, for the top analogy, I was envisioning the Earth's magnetosphere shifting and interacting differently with the solar fields and "wind". Conventionally, there is obviously no "friction" as there would be on Earth, but perhaps friction's "equivalent" could be found in a less efficient Earth-Sol field relationship.

I was thinking that if the magnetic poles had started their constant shifting, as the result of some event, that this shift in the planet's magnetosphere as it is oriented towards the sun creates a slight wobbling of the magnetosphere, exposing more or less of the field to the solar wind. I tried to envision what happens as more of the solar wind interfaces with the magnetosphere and visualize variations causing ever so miniscule longterm variations in rotation speed. Subtle field balances and factors, that remain undiscovered, may still dictate or influence the timetables of planetary rotation or orbit mechanics.

Take a look at the path the geomagnetic north pole has traveled since its discovery:

With such a FAST adjusting planetary magnetic field, it is almost unfathomable to assume that it's shifting has NOT influenced regional temperatures and climate conditions. In the global warming research I have encountered - I have yet to see ANY white paper that takes into account or addresses this key integral even in those that give passing reference to solar variation.

Combine these elements, along with solar variation, into the global warming issue and I think warming and cooling cycles are far, far more complex than anyone realizes.

Just more food for thought, and another variable to be addressed in the great global warming debacle.
