Could there be any connection, as well as correlation, between the
reduced
magnetic field and increased co2 or warming? Or could all be caused
by
some
other factor, perhaps galactic in origin?

I've looked into it. The system is chaotic, so even in theory there
is no predicting it. No one knows any details about how it works.


The magnetic field of the Sun reverses every eleven years. In the
Earth the iron core resists this, so the reversal has no period. The
average is about 50,000 years, but it can be up to a million years.
By they way, a recent computer simulation showed that the polarity of
the core is opposite that outside of the core.


Finally, the magnetic field of the earth is about double of its
average over the lifetime of the Earth, so it is much stronger than
usual.

There has been some great info coming in lately about the movement of
solar magnetic fields, and yet no connection has been made with GCR
seeding clouds at the poles, or at the SAA.

can i quote you on that,


=Yep.


because i never claimed the it did not exist,
i said the connection has not been found. Now thats why i said the
best area to study the GCR cloud seeding link is the place where the
magnetic field dips, the SAA.


=And the poles?- Hide quoted text -

looking for gcr seeded low cloud formation in the region of the SAA
one should seperate out enso and the solar cycle. *The poles are
subject to a unique cloud formation caused by reactions in the upper
atmosphere creating polar stratospheric clouds, PSC's. *This means one
should try to establish a *connection between GCR flux, polar
stratospheric clouds and low cloud formation over the poles.

take some time on your vacation maybe do some light reading into the
subject, then come back to this thread.
