8. Correlation between the Temperature of the Earth and Earth’s Global Magnetic Field
Long-term coincidence between climatic temperatures of the Earth on the one hand and the global strength of the MF of the Earth on the other is a well-known and accepted fact.
Figure 10 and
Figure 11 show the temperature and magnetic data sets. In
Figure 12 these data are combined. After the last Ice Age, it took our planet 4000 years to reach the climatic temperature we have today. Periods with greater thermal heat releases from the interior of the Earth, especially in the Arctic Ocean, can cause a diminishing ability of the Arctic Ocean to properly participate in the process of cooling down the warm water masses of the Gulf Stream as well as to release frozen magnetic flux.
The coinciding data clearly indicate that the cause of ice ages is almost completely misunderstood and that Milankovitch cycles are far from enough to fully understand the cause-effect process
(Milankovitch Cycles) .
Figure 12 shows the red graph (Earth’s magnetic field) intensely following the temperature graph (black graph). As can be seen, the magnetic field does not coincide with the much faster variations in the temperature graph, meaning the ones varying from a couple of hundred years to a couple of thousand years.
The reason is that the strength of the magnetic field is determined by two factors:
Figure 10. Temperature variation 100,000 years.
Figure 11. The dipole field for the past 82,000 years.
Figure 12. Atmospheric temperature and magnetic magnitude 0 - 80,000 years B.P.
· partly determined by either the heat flow and/or solar activity variations shown by
(Henrik Svenmark) ;
· and partly determined by MNP in an area with various magnetic susceptibility. The fast, stray MNP causes the quick variation of the magnetic field.

11. Conclusion
In conclusion, there is no need for an electromagnetic inner dynamo theory to explain:
· the periods of the basic magnetic state,
· the integration process,
· the magnetic pole reversal,
· the magnetic anomalies,
· the movement of the magnetic poles,
· anything else...
We are dealing with a simple and completely natural ferromagnetic process in the Earth’s crust busted by the solar wind (and nothing more than that). Much points in one direction: areas containing thermal heat play a role in shaping the FMF of our planet (because these areas hold very great integrating forces on the local level as well as in relation to the global field). An unknown contribution to the cause of ice ages could very well be less emission of inner heat.
The largest contribution to climatic change (also these days) is most likely the correlation between solar activity and cosmic radiation reaching the Earth resulting in cloud formations as shown by Henrik Svensmark and his team
(Henrik Svenmark; The Sun Allergy of Climate Researchers; Henrik Svensmark’s Research) . As the ocean accumulates heat, a delay in the cause-effect must be expected.
A consequence must be that periods of solar activity are not always brief (which means not only periods of 11 years or periods of a few hundred or thousand years) but also periodic solar activity cycles that last 100,000 years—before that 41,000 years and before that 15,000 years. This is required in order to be able to link the coincidence between climatic temperature and the Earth’s magnetic field.
It is commonly known that the climate debate suffers due to a lack of knowledge about the cause and effect relationship between a number of climatic temperature variations that have occurred in history without being able to blame human emission of greenhouse gas in any way. Only when we are...

I've not seen much about this lately but it was given some news time in the 90s if I recall.
