Earth's Climate, Solar Cycle 23, and the Solar Oxygen Crisis

The recent "solar oxygen crisis" may offer new insight into the stability and internal composition of the Sun and its influence on Earth's climate. *Data collected now and over the next solar cycle may show if the Sun is:
a.) A benevolent ball of hydrogen with a steady, hydrogen-fusion reactor at its core, or
b.) The remnant of a supernova that acts as an erratic, magnetic plasma diffuser and emits hydrogen as smoke from its central neutron-rich furnace.
Sunspots and solar surface magnetic activity from the latest solar cycle, solar cycle 23, peaked in 2000-2002. *On 15 February 2001 NASA reported that the Sun's magnetic field had flipped.

Since then reports of a "solar oxygen crisis" have increased as solar surface magnetic activity decreased.
Is this a coincidence? *Or is it confirmation that the Sun is a magnetic plasma diffuser that more selectively moves lightweight elements to its surface during periods of higher magnetic activity?

On 7 June 2006 Tom Ayres presented a paper entitled "The Solar Oxygen Crisis" at the High Altitude Observatory in NSF's National Center for Atmospheric in Boulder, CO:

Dr. Ayres' paper starts with these two revealing statements:
1. "In recent years, a number of studies of the solar oxygen abundance--based on detailed 3-D simulations of photospheric convection--have pointed to values nearly a factor of two smaller than recommended as recently as a decade ago. In fact, each new study seems to outdo the previous one in recommending a progressively lower oxygen abundance [EACH NEW STUDY SEEMS TO OUTDO THE PREVIOUS ONE IN RECOMMENDING A PROGRESSIVELY LOWER OXYGEN ABUNDANCE], most recently even below 400 ppm (parts per million relative to hydrogen; earlier recommended values were near 800 ppm)." [Caps inserted in parentheses for emphasis. OM]
2. "At the present rate, the Sun will be oxygen free in around 2015."
This sad fate for mother Sol may be averted if b.) is correct and our Sun is a magnetic plasma diffuser that more selectively moves lightweight elements to its surface during periods of higher magnetic activity. Between now and 2015, solar cycle 24 is expected to exhibit peak surface magnetic activity in 2011-2012.
Yesterday (2 May 2007) brought another intriguing news report of the impending "solar oxygen crisis."

According to this latest report the Sun contains about half as much oxygen, carbon, nitrogen, and neon as previously thought. Might that measurement instead indicate the presence of twice as much iron as expected, instead of half as much oxygen, carbon, nitrogen, and neon??
[The arXiv link to the paper to appear in The Astrophysical Journal 660:L153-L156, (10 May 2007), indicates that the oxygen/iron ratio (O/Fe) was measured. *See *

If the abundance of iron (Fe) increases at the Sun's surface during solar minimum, because the magnetic plasma diffuser is less effective then, this might be observed as a decrease in the O/Fe ratio and misinterpreted as an indication that oxygen is vanishing, i.e., the solar oxygen crisis.
Another study suggests that other sun-like stars also act as magnetic plasma diffusers.
Three years ago, UC Berkeley astronomers Jason Wright and Geoffrey Marcy completed a survey of other stars during periods of low surface magnetic activity, like the 70 year period from 1645 until 1714 AD. *This was
the coldest part of the Little Ice Age in Europe and North America, when early astronomers reported almost no sunspot activity.

Although the survey was intended to be of "sun-like" stars, at the end of the survey the astronomers concluded that the stars were "not sun-like at all, but are either evolved stars or stars rich in metals like iron and nickel."
Continued measurements of the O/Fe ratio at the surface of the Sun during solar cycle 24 may explain the surprising findings of the UC Berkeley astronomers for distant stars and *the operation and internal composition of the Sun and its influence on Earth's climate.
