3) Other indications of the absolute failure of
the geomagnetic field model is the so called heat flux problem or the recent discovery of very, very rapid geomagnetic field intensity and inclinition changes (All researchers agree that the very, very rapid field changes could not possibly be due to changes in the earth's core.
At present it seems advisable to consider if the choice of
geomagnetic field model would make a significant difference to any interpretation.

The somewhat contradictory results for the similarity of radionuclide - based dipole reconstructions and
geomagnetic field models on these time scales point out that
geomagnetic field models have to be improved further before they can provide a truly robust means to eliminate the influence of geomagnetic variability in cosmogenic radionuclide production studies.
We then review recently developed millennial - scale spherical harmonic
geomagnetic field models and compare their dipole predictions to virtual axial dipole and virtual geomagnetic pole (VGP) reconstructions, discussing uncertainties in absolute values and variations.

The study brought together data from several spacecraft, as well as supporting observations from solar wind probes and ground - based
geomagnetic observatories, to develop a
model that describes the Earth's magnetic
field and its interaction with the solar wind not just theoretically as had been the case previously, but based on actual measurements.
Other evidence [which I will present in future articles] seems to indicate that these same climate
models are NOT realistically simulating such factors as atmospheric water vapour, clouds, solar energy fluctuations and cosmic ray effects, Earth's changing
geomagnetic field, and Earth's interior heat with consequent surface heat variations.
Here we review several spherical harmonic
models and compare their dipole
field predictions to reconstructions based on virtual axial dipole moments and virtual
