repeat of Laschamp Geomagnetic Excursion 41,000 B.P.

The Laschamp Geomagnetic Excursion 41,000 B.P.

I have noticed that a lot of you are clicking on this button so I thought more of you who didn't know about it should know about it too. Basically, a Geomagnetic excursion is what I believe the Earth has been going into since at least the early 1900s. If you look at the slowly increasing speeds that the magnetic North pole is moving towards Siberia  it likely is evidence of a Geomagnetic excursion or less likely of a maybe 1 chance in 10 of turning into a full pole reversal that began around 1900 or so and has increased as the speed of the magnetic North moving towards Siberia out of Canada. However, more likely it is another geomagnetic excursion.

My thought is that it might not be fully that it is humans causing this change in the weather through global warming. It might just be the incredible weakening of our magnetosphere from what likely is a geomagnetic excursion. They usually last around 1000 years or more and cause many extinctions of creatures on earth. They also create mutations or (fast evolution) of those species who survive on earth with a Geomagnetic excursion occurs. They also make us more susceptible to Solar Flares because our magnetosphere cannot protect us very much during what is happening now. Another problem is potentially it could render all electrical technology defunct in one or all places on earth in the process of this. So, in a complete pole reversal for example everything electrical likely wouldn't work on earth because it all would have to be redesigned. However, it might not be able to be redesigned until it stopped changing and settled down and this might take 1000 years or more.

I cannot say for sure what exactly is happening here because of all this. But, scientists have said our magnetosphere which protects us from Solar Flares has weakened incredibly especially since 2000 and now has cracks that allows all sorts of rays and other stuff in especially from the polar circles towards the poles.

Since I couldn't seem to load my comments at the end without destroying other articles by printing over them I will put my end comments at the beginning to see if that works better:

So, to make a long story short the north and south poles were all over the place for about 2000 years 41,000 years ago before returning to something like we have been experiencing during recorded human history. The reason this is important is that we may be in another Geomagnetic Excursion now. Suspicion for this is because of a moving magnetic north pole (PRESENTLY 40 MILES PLUS A YEAR AND BREAKS IN THE MAGNETOSPHERE) Since the magnetosphere of earth was only 10% as strong as during the 19th and 20th centuries during that 2000 years likely many species went extinct during those times. Possibly because of cosmic ray exposure and ultra violet exposure many species died out or some mutated somewhat or more likely both these things happened.  

So, since geomagnetic excursions appear to be cyclical events like the tide of the oceans of earth we may be in for a geomagnetic excursion. One of the effects of a geomagnetic excursion is extreme weather changes and ice ages.

Not being a trained Geophysicist I had trouble deciphering what they were saying  in the abstract below. for example:

Magnetic declination

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Example of magnetic declination showing a compass needle with a "positive" (or "easterly") variation from geographic north.

Magnetic declination is the angle between magnetic north (the direction the north end of a compass needle points) and true north. The declination is positive when the magnetic north is east of true north. The term magnetic variation is a synonym, and is more often used in navigation. Isogonic lines are where the declination has the same value, and the lines where the declination is zero are called agonic lines.
Somewhat more formally, Bowditch defines variation as “the angle between the magnetic and geographic meridians at any place, expressed in degrees and minutes east or west to indicate the direction of magnetic north from true north. The angle between magnetic and grid meridians is called grid magnetic angle, grid variation, or grivation. Called magnetic variation when a distinction is needed to prevent possible ambiguity. Also called magnetic declination.” [1] and second

Orbital inclination

Inclination in general is the angle between a reference plane and another plane or axis of direction.

[edit] Orbits

The inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit. It is the angular distance of the orbital plane from the plane of reference (usually the primary's equator or the ecliptic), normally stated in degrees.^[1]
In the Solar System, the inclination of the orbit of a planet is defined as the angle between the plane of the orbit of the planet and the ecliptic — which is the plane containing Earth's orbital path.^[2] It could be measured with respect to another plane, such as the Sun's equator or even Jupiter's orbital plane, but the ecliptic is more practical for Earth-bound observers. Most planetary orbits in the Solar System have relatively small inclinations, both in relation to each other and to the Sun's equator. There are notable exceptions in the dwarf planets Pluto and Eris, which have inclinations to the ecliptic of 17 degrees and 44 degrees respectively, and the large asteroid Pallas, which is inclined at 34 degrees.

We have recovered two new high-resolution paleomagnetic records of the Laschamp Excursion (∼41,000 calendar years B.P.) from deep-sea sediments of the western North Atlantic Ocean. The records document that the Laschamp Excursion was characterized locally by (1) declination changes of ±120°, (2) inclination changes of more than 140°, (3) ∼1200-year oscillations in both inclination and declination, (4) near 90° out-of-phase relationships between inclinations and declinations that produced two clockwise loops in directions and virtual geomagnetic poles (VGPs) followed by a counterclockwise loop, (5) excursional VGPs during both intervals of clockwise looping, (6) magnetic field intensities less than 10% of normal that persisted for almost 2000 years, (7) marked similarity in excursional directions over ∼5000 km spatial scale length, and (8) secular variation rates comparable to historic field behavior but persisting in sign for hundreds of years. All of these features, with the exception of anomalously large directional amplitude, are consistent with normal magnetic field secular variation. Comparison of our Laschamp Excursion paleomagnetic records with other late Quaternary excursion records suggests that there is a group of excursions, which we term class I, which have strikingly similar patterns of field behavior and likely share a common cause as part of the overall core dynamo process. Three general models of secular variation are described that can qualitatively produce class I excursions. On the basis of these observations we conclude that class I excursions, epitomized by the Laschamp Excursion, are more closely related to normal secular variation and are not necessarily a prelude to magnetic field reversal.
