Consequences of the next geomagnetic field collapse, concomitant with a magnetic polarity reversal or excursion, have been greatly underestimated as based upon a widely-accepted, but physically-impossible geoscience paradigm. The underlying causes of geomagnetic field collapse are inexplicable in that flawed paradigm wherein geomagnetic field production is assumed to be produced in the Earth’s fluid core. Here I review the causes and consequences of geomagnetic field collapse in terms of a new geoscience paradigm, called Whole-Earth Decompression Dynamics, specifically focusing on nuclear fission georeactor generation of the geomagnetic field and the intimate connection between its energy production and the much greater stored energy of protoplanetary compression. The nuclear georeactor is subject to a staggering range and variety of potential instabilities. Yet, its natural self-control mechanism allows stable operation without geomagnetic reversals for times longer than 20 million years. Geomagnetic reversals and excursions occur when georeactor sub-shell convection is disrupted. Disrupted sub-shell convection can occur due to (1) major trauma to Earth such as an asteroid collision or (2) change in the charge particle flux from the sun or change in the ring current either of which can induce electrical current into the georeactor via the geomagnetic field causing ohmic-heating that can potentially disrupt sub-shell convection. Further, humans could deliberately or unintentionally disrupt sub-shell convection by disrupting the charge-particle environment across portions of the geomagnetic field by nuclear detonations or by heating the ionosphere with focused electromagnetic radiation. The use of electromagnetic pulse weapons is potentially far more devastating to humanity than previously imagined, and should be prohibited. During the next polarity reversal or excursion, increased volcanic activity may be expected in areas fed by georeactor heat, such as the East African Rift System, Hawaii, Iceland, and Yellowstone in the USA. One potentially great risk is triggering the eruption of the Yellowstone super-volcano.

“…Chapman et al (2018) characterized space weather parameter distributions, including AE and Dst, for the last five solar maxima and showed that the tail of their distributions follows a single functional form, independent of the strength of each solar cycle. Kakad and Kakad (2020) examined the probability distribution functions associated with AE and Dst indices and noticed significant narrowing in the probability distribution function for solar cycle 24 as compared to cycles 20-23, suggesting a decrease in the strength of associated current systems during this time. Extreme value theory (EVT) may be applied to model the index distributions.…”

Variation of Geomagnetic Index Empirical Distribution and Burst Statistics Across Successive Solar Cycles

Geomagnetic response at Earth to solar driving is a problem of long-standing and topical interest (Baker, 2000;Milan et al., 2017;Pulkkinen, 2007), both in terms of understanding the underlying fundamental nonlinear physics of the Sun-Earth system and improving space weather preparedness. Geomagnetic indices such as the auroral electrojet (AE) index (Davis & Sugiura, 1966) and disturbance storm-time (Dst) index (Sugiura, 1964) and their higher resolution counterparts (Gjerloev, 2012) are central to characterizing space weather activity and are available over the last five solar cycles.Statistical studies of long-term geomagnetic indices are aimed both at fundamental understanding of the nonlinear magnetospheric response to solar driving and quantification of space weather risk.
