Recent posts on polar shift , weather patterns , global warming , earths quakes , volcanic activity , are they all related to the shifting of
the poles.
Yes and no.
... a polar shift causes electrical interference in animals and in the weather and in the earths crust as in earth quakes..
I believe you're looking at two different definitions of "polar shift": one (a
magnetic pole shift -- or reversal) which happens on the
average of every couple hundred thousand years; and a
shift in the axis-of-rotation poles which could only happen if the Earth were impacted by
another planet (in which case the Earth would probably turn into another asteroid belt).
The first 'polar shift' is a reversal of the magnetic poles. No one is ablsoutely sure
why this happens, but we know
when it happens
by looking at the way certain rocks in the middle of the Atlantic Ocean are magnetized. We know that this happens about once every seventy thousand
years on the average (if I remember correctly); and we also know it's not a catastrophic event, since there is no correlation between these magnetic
field reversals and die-offs in the geological and paleontological records. Admittedly, some species which migrate by picking up magnetic cues (like
the monarch butterfly) may change their patterns, but it won't be a catastrophic event like the Chicxulub Strike in the Yucatan which ended the
Cretaceous Era.
A physical shift of the axis-of-rotation pole (in other words, the point which points to the Pole Star) simply will not happen. Given that the Earth
weighs sextillions of tons and that its rotation imparts a tremendous conservation-of-angular momentum stability, any physical force capable of
changing the axis of rotation would probably destroy the Earth itself. In any event, it's only happened once in the entire solar system (to Neptune)
and even that may because of some angular-momentum jiggery-pokery some 4 billion years ago when the solar system was still not much more than an
accretion disk.
Your input in this matter may explain why where is was cold is now getting warmer and where it was warm is now getting cooler...
I think the climate changes, while very serious, can be explained by something a lot simpler. An overall warming of the Earth (probably caused or at
least exacerbated by human activity) causes a melting of the polar icepacks and resultant decrease in the ocean salinity. Because of this, the
"conveyor effect" of the Gulf Stream (and probably the Japan Current, although it's kind of early to tell) is lessened, which means that places
which are warmed by these currents (like England) could become much colder.
But earthquakes and volcanic activity are almost always caused by movements in the tectonic plates; specifically, the boundaries between them. I am
not aware of any correlation between climate and earthquakes, although certainly large volcanoes can and do cause climate changers, usually by the
expelled ash in the stratosphere causing a cooling effect. If such stuff interests you, may I suggest
