Something wrong with sun.....

I simply dismissed "global warming" as a form of religious fervor a long time ago. I'm still reminded of the daily solar constant belief when I was in junior high which postulates that on any square meter of the Earth's atmosphere, the amount of sunlight doesn't vary from year to year. Therefor, if sunlight remains "constant" then ice ages or global warmings would seem to be a complete impossibility. Unless another ingredient is involved.

This brings us to co2 gas . Only co2 is in sufficient amount to affect the whole planet by acting as a blanket trapping heat or allowing heat to escape. This would imply that global warming or cooling  can only be caused by co2 levels fluctuating  in the atmosphere. Hence global warming theory answers a lot of questions about our planets history. Up until a few years ago, volcanoes being the main culprit. Now it's my Suzuki's fault. Why? Because too many of the "greatest minds in the country" hate "big oil". So any excuse to punish the bastards becomes more or less a crusade.

Sounds like good ol' religion to me.

 Of course, one must take into account that at one time the "greatest minds in the country" spent many a day debating how many angels could dance on the head of a pin. (Infinite. Or as many as you can find. Heh heh) That sounds suspiciously religious too, don't you think?

Anyways,  the sun doesn't appear to be co-operating and the "greatest minds in the country" are getting pissy:

Solar geomagnetic index reaches unprecedented low – only “zero” could be lower – in a month when sunspots became more active « Watts Up With That?
We then had a string of sunspots in December that marked what many saw as a rejuvenation of solar cycle 24 after a long period of inactivity. See December sunspots on the rise

It even prompted people like Joe Romm to claim:

The hottest decade ends and since there’s no Maunder mininum — sorry deniers! — the hottest decade begins

But what Joe doesn’t understand is that sunspots are just one proxy, the simplest and most easily observed, for magnetic activity of the sun. It is the magnetic activity of the sun which is central to Svensmark’s theory of galactic cosmic ray modulation, which may affect cloud cover formation on earth, thus affecting global temperatures. As the theory goes, lower magnetic activity of the sun lets more GCR’s into our solar system, which produce microscopic cloud seed trails (like in a Wilson cloud chamber) in our atmosphere, resulting in more cloud cover, resulting in a cooler planet. Ric Werme has a nice pictorial here.

When I saw the SWPC Ap geomagnetic index for Dec 2009 posted yesterday, my heart sank. With the sunspot activity in December, I thought surely the Ap index would go up. Instead, it crashed.
