” The data is in progress for a correlation of the geomagnetic field secular decrease (from 8.055 (10)22 amp-m2 to 7.776 (10)22 amp-m-2 ), and the overall increase in global temperatures. The global temperature increases, are a function of the geocore joule-heating from the increased electrical current densities within the Earthâ€™s core.
Heat is then transferred from the core through the mantle, to the lithosphere (crust), hydrosphere (oceans), and atmosphere. Hydrothermal vents (HTVs) indicate the presence of heat transferred from the aesthenosphere (mantle) to the oceans.
This analysis includes the developing ratio: Hï =(1/T)r relationship, such that the geomagnetic field intensity decrease is inversely proportional to the geocore joule temperature increase.
ïï€ is the magnetic field inductive capacity and r is the radial position vector for temperature variations within the core. (Isothermal distribution is not assumed.)
The anomalous years are 1940-1960 as shown in the enclosed 2 Geomagnetic Field Decay. In this interval the geomagnetic field (GMF) intensity (decelerated) showing an apparent increase slightly, resulting in a commensurate decrease in Arctic temperatures.
After this interval the GMF decay accelerated in accord with Ampereâ€™s Law, and the Arctic temperatures, presumably a function the Earthâ€™s geocore electrical joule-heating, caused by the GMF decayâ€¦.increased.
