JUST IN: New Scientific Findings Reinforces Battros Research on Galaxy-Sun-Earth-Human Connection

Today's release of the latest discoveries of Earth's magnetic field reversal goes to the heart of Mitch Battros new "equation" published earlier this year. Discoveries highlighted is confirmation of a "much shorter period in the time-linked-means of which the field reversal took place" - from the beginning short distance (magnetic north) bouncing in latitude and longitude, to the end stages of magnetic north dipping below the equator, and finally to its full magnetic flip.

A New Equation is Born: Increase Charged Particles -->Decreased Magnetic Field -->Increase Outer Core Convection -->Increase of Mantle Plumes -->Increase in Earthquake & Volcanoes -->Cools Mantle and Outer Core -->Return of Outer Core Convection (Mitch Battros - July 2012)

A second new discovery has to do with rapid climate change; a third is the increase and result of volcanoes, especially caldera's and submarine (underwater) volcanoes many of which are located on or near subduction zones, rifts, and trenches. These events are associated with an increase of mantle plumes.

The hot core of Earth leads to the ascent of heated rocks in form of large bubbles called 'mantle plumes' that separate from the core-mantle boundary and make their way up to the surface of Earth. This is how Hawaii, Iceland, and several islands or small continents came into existence. This increases the local heat flux out of Earth's core and in turn modifies the generator of the geomagnetic field.

In a related new discovery scientists at the University of Liverpool have discovered that variations in the reversal rate of Earth's magnetic field may be caused by changes in heat flow from Earth's core into the base of the overlying mantle.

Earth is made up of a solid inner core, surrounded by a liquid outer core, in turn covered by a thicker or more viscous mantle, and ultimately by the solid crust beneath our feet. The magnetic field is generated by the motions of the liquid iron alloy in the outer core beneath Earth's crust. These motions occur because the core is losing heat to the overlying solid mantle that extends up to the crust on which we live.

The mantle itself is also in motion. This mantle motion is responsible for the drifting of the continents at the surface - and also responsible for earthquakes, volcanoes, and temporal changes in the climate.

Some 41,000 years ago, a complete and rapid reversal of the geomagnetic field occurred. Magnetic studies of the German Research Center for Geosciences on sediment cores from the Black Sea - show that during the period of the last ice age, a compass at the Black Sea would have pointed to the south instead of north.

Moreover, data obtained by researchers Dr. Norbert Nowaczyk and Prof. Helge Arz, from GRCG together with additional data from other studies in the North Atlantic, the South Pacific and Hawaii - prove that this polarity reversal was a global event. Their results are published in the latest issue of the scientific journal Earth and Planetary Science Letters.

What is remarkable is the speed of the reversal: "The field geometry of reversed polarity, with field lines pointing into the opposite direction when compared to today's configuration, lasted for only about 440 years, and it was associated with a field strength that was only one quarter of today's field," explains Norbert Nowaczyk. "The actual polarity changes lasted only 250 years. In terms of geological time scales, that is very fast." During this period, the field was even weaker, with only 5% of today's field strength. As a consequence, Earth nearly completely lost its protection shield against hard cosmic rays, leading to a significantly increased radiation exposure.

This is documented by peaks of radioactive beryllium (10Be) in ice cores from this time, recovered from the Greenland ice sheet. 10Be as well as radioactive carbon (14C) is caused by the collision of high-energy protons from space with atoms of the atmosphere.

The Laschamp Event

The polarity reversal now found with the magnetisation of Black Sea sediments has already been known for 45 years. It was first discovered after the analysis of the magnetisation of several lava flows near the village Laschamp near Clermont-Ferrand in the Massif Central, which differed significantly from today's direction of the geomagnetic field. Since then, this geomagnetic feature is known as the 'Laschamp event'. However, the data of the Massif Central represent only some point readings of the geomagnetic field during the last ice age, whereas the new data from the Black Sea give a complete image of geomagnetic field variability at a high temporal resolution.

Abrupt Climate Changes and a Super Volcano

Besides giving evidence for a geomagnetic field reversal 41,000 years ago, the geoscientists from Potsdam discovered numerous abrupt climate changes during the last ice age in the analyzed cores from the Black Sea, as it was already known from the Greenland ice cores. This ultimately allowed a high precision synchronization of the two data records from the Black Sea and Greenland.

The largest volcanic eruption on the Northern hemisphere in the past 100,000 years, namely the eruption of the super volcano 39,400 years ago in the area of today's Phlegraean Fields near Naples, Italy, is also documented within the studied sediments from the Black Sea. The ashes of this eruption, during which about 350 cubic kilometers of rock and lava were ejected, were distributed over the entire eastern Mediterranean and up to central Russia.

Across the bay of Naples from Pompeii, where thousands were incinerated by Mount Vesuvius in 79 A.D., lies a hidden "super volcano" that could kill millions in a catastrophe many times worse, scientists say.

The boiling mud and sulphurous steam holes of the area west of Naples known as the Campi Flegrei or Phlegraean Fields, which the ancients thought was the entrance to hell, also could pose a danger of global proportions with millions of people literally living on top of a potential future volcanic eruption.

The Campi Flegrei are similar to the Yellowstone caldera in the U.S. but of more concern because they are in an area populated by around 3 million people in the Naples hinterland.

These three scenarios, a short and fast reversal of Earth's magnetic field, short-term climate variability of the last ice age and the volcanic eruption in Italy, have been investigated for the first time in a single geological archive and placed in precise chronological order.
