NY Times article link and comments on earth EMF
"As scientists began to understand the importance of reversals in
the planet's history, they examined the fossil record for evidence
of damage to life. In 1971, Dr. James D. Hays of the Lamont-Doherty
Earth Observatory of Columbia University noted a strong correlation
between recent flips and species extinctions of tiny marine
creatures known as [
radiolarians. "The evidence," he wrote in The Bulletin of the
Geological Society of America, "is strongly suggestive that magnetic
reversals either directly or indirectly exert a selective force.""
Where the error is is that the end of the radiolarians is 'caused'
by the change in the EMF and not the other way around.
Same with the issue of the core. The reason the strikes from
convection are ignored as a forcing which causes the EMF is that
scientists who study the physics and the EMF are generally not
educated in biological sciences, and even within the field of
biology gaia isn not apreciated as something which could give a
coherant order to such a large scale phenomenon.
See Spot run. See Spot jump. See Occum's razor cut.
Something dead like the core could not possibly MODULATE the EMF
and, therefore, modulate the earth's atmosphere. Solar winds free to
wisk away the atmosphere or not by the chaotic movements of the core
doesn't get it done.
But the earth's atmosphere IS modulated.
