Skip to comments.Scientists probe link between magnetic polarity reversal and mantle processes
Posted on 08/03/2012 8:50:34 AM PDT by Errant
Scientists at the University of Liverpool have
discovered that variations in the long-term reversal
rate of the Earth's magnetic field may be caused by
changes in heat flow from the Earth's core into the base
of the overlying mantle.
The 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.

I knew it, I just knew it!
Additionally, in recent news, are findings of historical evidence correlating low sunspot activity with increased volcanic activity on earth. What the heck could cause that? LOL
Yes it is. Last I heard, up to 85 miles per year now. Very interesting times we live in!
Don’t “mantle processes” include subduction?
Resulting pressure waves could contribute to increased thermal variations and increased earthquake and volcanic activity on much shorter time frames. It would also explain earthquake cycles and the fact that these cycles encompass earthquakes at all depths.
Just thinkin' out loud here... ;)
Yes, where two tectonic plates converge, a subduction zone will form and the oceanic plate will sink back into the mantle.
Good Ping....thanks bud!
The evidence is there. There is a broad consensus in the scientific community. The UN panel study is incontrovertible. The science is settled. THIS CHANGE OF THE EARTH’S MAGNETISM IS MAN MADE.
All iron ore mining must stop right now!
LOL! Of course, it’s also daunting to contemplate how easily that could come about in reality.
And don’t forget the next catastrophy humankind is called upon to put a stop to: Continental Drift! I suppose if great pylons were driven into the earth along all the world’s coastlines we can save our children and our children’s children from the continents crashing into each other. But we must act quickly and decisively.
Sounds like another cash for clunkers program is needed to restore the earth's natural iron formations! :)
Actually that sounds backward. Wouldn't low sunspot activity (less turbulent Sun) mean less volcanic activity?
I know. In the article below, they contribute it to a lag. I think there is something at work we haven't figure out yet, since SP minimums can last many years.
