Recently there was a story on a model showing declining ice along the
Cascades and I want to pass a couple of thoughts. First, these models
are basically junkscience because they don't couple cloud behaviors,
missing substantially what the biosphere does and what EMFs do to
cloud behaviors. That said, there was a Stanford study that basically
said that the glaciers along the West Coast are in decline. This is
not a model but an observation.
I have meantioned with interest that the leading scholar who
advocates climate "flip flops" is none other than a brain
evolutionist out of U. Washington named William Calvin. He is a
prolific writer. Neo glacials have commenced most recently along the
Cascades, so just by history this is a place to watch.
Let me discuss in a nutshell two possible mechanisms. One is the fact
that as the oceans warm one of the prime currents by Alaska is a
counter currrent. That is, its induction direction is such that it
negates a displacement current from ionosphere to ocean, which causes
cirrus or ice in clouds to elongate and find difficulty forming
relative to clouds not so elongated. Okay. So here is the flip flop
or the paradox. As oceans become warmer, they paradoxically will
induct more both for and againce a capactive displacement current.
Therefore, along the Alaskan counter cirrus may form explosively and
at the same time north and south of the counter no clouds can form at
all, allowing heat to escape out into space. The fundimental cause of
this would be the oceans warming enough to become more conductive and
for the induction differences, relative to one another, to begin to
influence the cloud microphysics.
The other significant problem would be the meandering of the earth
EMF or the outright loss of it, with loss of atmosphere and a wholly
changing earth climate dynamics.
Now, both of these kinds of changes occur naturally. The recent Dane
research on cosmic ray flux is one such forcing that changes the
dynamic such. The orbital changes in the moon can cause roiling
patterns that upset this balance. Even some changes in solar cycling
can cause some changes--IMHO having less to do with major climate
chances except on longer timescales due the the primary forcing about
amplification, not signal, where solar electrical and radiative
forcings are less significant than how the clouds behave to captures
and modulate these signals.
That said, the complexities of climate are modulated by the
biosphere. And that is where the primary changes are occurring from
human activity--these are global biological changes that are afoot.
