Coming Maunder?

You'll never be lacking a barber on the Sun, if this Japanese research is true:

Apparently the Sun is soon to have four poles rather than two, the result of an enfeebled condition.
From the article:
"Officials of the National Astronomical Observatory of Japan and the Riken research foundation said on April 19 that the activity of sunspots appeared to resemble a 70-year period in the 17th century in which London’s Thames froze over and cherry blossoms bloomed later than usual in Kyoto.
In that era, known as the Maunder Minimum, temperatures are estimated to have been about 2.5 degrees lower than in the second half of the 20th century.
The Japanese study found that the trend of current sunspot activity is similar to records from that period.
The researchers also found signs of unusual magnetic changes in the sun. Normally, the sun’s magnetic field flips about once every 11 years. In 2001, the sun’s magnetic north pole, which was in the northern hemisphere, flipped to the south.
While scientists had predicted that the next flip would begin from May 2013, the solar observation satellite Hinode found that the north pole of the sun had started flipping about a year earlier than expected. There was no noticeable change in the south pole.
If that trend continues, the north pole could complete its flip in May 2012 but create a four-pole magnetic structure in the sun, with two new poles created in the vicinity of the equator of our closest star."
End excerpt.
So we may be entering another Maunder Minimum! Maunder coincided with the "Little Ice Age", a period of unusual cold. This was critical in many ways; the Mayans saw their civilization decline during the LIA, and the Mound Builders in the Midwest civilization collapsed with the coming of the LIA. Europe's colonization of the world was spurred on by the deprivations of this period, and the subsequent decline of many aboriginal civilizations as they were no longer able to adequately feed themselves due to the cooling climate. It was a hard time.
Maybe we need a little Global Warming after all?
