The geomagnetic field is believed to be generated by an internal dynamo mechanism and usually represented graphically by a bar magnet. Except that when we want to magnetise something, say a lump of ferrite to make an audio loudspeaker magnet, we place the ferrite inside a coil of copper wire and attach a large battery to the coil to generate a massive transient electric current that induces a magnetic field, or dipole, in the ferrite which then becomes magnetic. It’s the only way known to make magnets and thus magnetic fields.
- The Earth has an overall negative electric charge at its surface. Fact.
- It has an outer shell of positive electric charge that is the ionosphere. Fact.
- Further out into space there are two co-rotating Van Allen Belts, an inside one with positive charge, and an outer one with negative charge. Fact.
- Moving electric charges are called electric currents. Fact.
- Co-rotating electrical torii produce magnetic dipoles. Fact.
The Earth’s resultant geomagnetic field is thus the sum of at least 4 dynamic, co-rotating shells of electric charges, resulting in its quadrature nature. The outer Van Allen belt and earth surface rotating negative electric charges form the normal component of the geomagnetic field. The co-rotating positive charges, the inner Van Allen belt and ionosphere, form the inverse magnetic field. Together they form the dynamic composite geomagnetic field that is modulated by space weather. Polar wander occurs when either the normal or inverse magnetic fields change in strength. (There is a belief that the subsurface MOHO might represent another positive electric charge from thermionic emission but this cannot be tested in situ and hence not included in the model proposed here).
At present the resultant geomagnetic field is normal but as the solar magnetic field decreases in strength, (current drop) indicated by sunspot activity, the Earth’s normal field starts to weaken and allows an increase in the atmospheric positive electric charges to occur, thereby further strengthening the inverse field component. The relative changes in the normal and inverse magnetic fields then results in apparent magnetic polar wander. Physically the Earth remains rotating around its present axis and does not move.
The magnetic polar wandering isn’t caused by some unknown changes in some fictitious internal dynamo either, but from the logical outcome of the changing electric charge of the two major rotating charge shells that the Earth is centred in, the surface-ionosphere plasma double layer and the Van Allen Belts. The internal dynamo model was appropriate 100 years ago when no one knew of the solar wind, solar plasma and the Van Allen Belts. Today the facts have changed but the scientific problem is that we didn’t change our dynamo theory in the light of the new data or facts. As the famous British economist John Maynard Keynes put it, when the facts change, he changes his mind; what do we do? It’s called psychological habituation, or scientific stasis might be a better description. It should also be realised that the polar wander inferred from the paleo-geophysical data does not mean the continents moved. The present crustal motion from GPS data seems more due to thermal relaxation and shrinkage than to the horizontal motion from plate tectonics.
An increase in atmospheric positive electric charge, generally an increase in protons, from whatever source, will also cause additional physical disruption of the atmosphere caused by the catastrophic motion of large volumes of positive electric charges driven by various horizontal surface electric fields. Increase in atmospheric positive electric charge thus causes large changes in the weather systems as presently observed. And accompanying those changes in weather are the wandering poles. (Wandering who?)
Earthquakes, volcanic eruptions and massive atmospheric storms are probably caused by changes in the earth’s internal and external electric charge states, modulated by changes in the solar system dynamics, or space weather, which are then driven or forced by variations in the galaxy’s dynamics. And like the proverbial flea on the end of the elephant’s tail, we can’t do anything about it.
The geological record is thus replete with extinct life forms, preserved in the various sediments as the remnants of previous catastrophes as controversially documented in the biblical Old Testament, for example. Are these changes cyclic? Probably. Will they occur in the future? Maybe, if the past is a key. But who knows? The future is, after all, unpredictable, and the past cannot really tell us what the future holds.
The fact is the Earth is undergoing continual geological change as it degasses and reacts to the waning compressive forces, the plasma z-pinches, that formed it. The Earth’s biosphere is thus continuously adapting and changing in response to these changing environmental states. The newborn initially appears compatible with the physical environment it is born into, but behavioural habits start to build up as the life-form matures, to then become progressively incompatible with the changing environment; this process is biological ageing and hence biological evolution via procreation. Physical ageing is our response to climate change while paranoia and fear our psychological response to the same climate changes our ancestors experienced and which we dimly sense as a traumatic species collective subconscious memory we seem unable to free ourselves from and which has morphed into religion.
Biological species adapt to population culling catastrophes by population explosions so enough will survive to continue the process of evolution once the latest catastrophe wanes into the collective memory. Most life forms forget the past except humans who seem unable to free themselves from that past. (This memory is not Sheldrakian memory, by the way). We do this by becoming habituated to some specific pattern of thinking. Thinking is the continuous retrieval and repetition of memories until the process becomes automatic. Psychological addiction as it might be described, and no different to being addicted to chemical drugs. Constant thinking also causes us to isolate ourselves from reality by retreating either into our platonic mind caves and focussing our attention internally, or like young people isolating themselves from reality with ear-pods and music players.
The Earth’s climate is changing because the Earth is geologically changing, and there’s nothing we can do about it.
We are not causing climate change but it is changing us. And we will become as extinct as our ancestors who, and not extra-terrestrial aliens, built the megalithic structures, pyramids and polygonal stone works that litter the surface of the Earth and which continue mystifying us. We are them, as they say, except we don’t realise it because our cultural creation myths, based in fear, and assuaged by our metaphysical beliefs, led to the framing of the geological uniformitarian meme or paradigm during the 19th century. This has resulted in a completely disconnected, nonsensical geological framework devoid of catastrophe that has become the Western World’s cultural creation myth.
Species extinctions are normal and the means by which Life adapts to macro climate changes. Climate change is thus evolutionary. However, our metaphysical beliefs in the existence of abstract souls, egos, me, I, Id, are delusionary. But we believe them in order to escape the collective traumatic memories our species acquired from our ancestors during their catastrophic past. Our primary fear is losing our minds, souls or egos, not realising that those abstractions were the very means by which we initially used to cope with the Bronze Age catastrophes in the first place.
Gould and Eldridge were right, biological evolution is indeed punctuated. But to cope with all this depends on how quickly one can lose one’s religion, and the primal ancestral fear of climate change.
Update: I have purposefully ignored telluric currents as contributing to the geomagnetic field because these need to be aligned along the Earth’ equator and there doesn’t appear to be any evidence for this. Plate boundaries might be the locus of telluric currents however. And my apologies if the model here is too simplistic.
