Strange correlation between the strength of the Earth's magnetic field and the atmospheric oxygen content

Sabine Hossenfelder (see this) talked about the recently discover strong correlation between the strength of the Earth’s magnetic field and O₂ content the atmosphere (see this).

This is an extremely interesting finding from the TGD point of view. TGD is a theory of everything but unlike its competitors, it inspires a quantum theory of consciousness and of biology. The new view about magnetic fields differing from the Maxwellian view leads to the notion of field body/magnetic body accompanying any system, also the Earth. It predicts that the biosphere very probably behaves quantum coherently at the level of the magnetic body in the scale of Earth and even at very long scales.

In the TGD framework, space-time is identified as a 4-surface in H=M⁴× CP₂. This leads to a new view of classical, in particular electromagnetic fields differing in many respects from the Maxwellian view. One can assign a field body to a given physical system. Field bodies are carriers of phases of ordinary matter with non-standard value of effective Planck constant of h_eff, which can have very large values implying quantum coherence in even astrophysical scales. The field body is a key notion in the TGD based view of living matter.

The homology of CP₂ is non-trivial and this implies the existence of closed monopole flux tubes carrying monopole magnetic flux although no monopole charges are predicted. The monopole magnetic fields need no current as a source and are therefore stable unlike ordinary magnetic fields which disappear when the current generating them dissipates. This explains the stability of the Earth’s magnetic field (see this) and also the existence of magnetic fields in cosmological scales. The monopole magnetic fields are ideal from the point of view of biology (see this, this, this and this).

It is known that the changes in the magnetic field strength and its orientation have had strong effects on biology and consciousness. The local weakening of the magnetic field strength and Schumann resonance have been assigned also with disorders of societies by Callahan (see this and this). TGD suggests a model for the reversal of the magnetic field (see this and this).

About 500 million years ago, the Cambrian Explosion occurred and meant the mysterious appearance of highly evolved multicellular organisms. Where did they emerge from? In the TGD based view of cosmology (this and this), the cosmic expansion takes place as rapid jerks for astrophysical objects, including planets and the Earth. This suggests that this kind of rapid increase of the radius of the Earth by factor 2 took place about 500 million years ago and led to the burst of highly evolved multicellular life from the underground oceans to the surface. Oceans were formed and the photosynthesizing multicellular life forms oxygenated the oceans and also the atmosphere. There is indeed evidence for life in underground oceasn able to perform photosynthesis and TGD leads to an explanation for how this is possible (see for instance this and this).

As the figure 1 of the article (see this) about the correlation between magnetic field strength and O₂ percent of the atmosphere shows, both the oxygen percent in atmosphere and the strength of the magnetic field characterized by virtual geometric axial dipole moment started to grow about 500 My ago and is maximum about 300 My ago. TGD view of Cambrian Explosion suggests that the strengthening of the magnetic field, perhaps by the emergence of monopole flux tubes, implied a rapid evolution of the oxygen based life forms in the oceans created by the rapid expansion and caused oxygenation of the atmosphere.
