A lecture by professor Hiroko Miyahara of the University of Tokyo provides additional support to the Svensmark theory of cosmoclimatology, finding that both solar geomagnetic activity and the polarity of geomagnetic activity have significant effects upon cosmic rays and cloud formation. The polarity of solar geomagnetic activity flips with a 22-year cycle, with periods of negative polarity [such as the current solar cycle] having a greater effect upon cosmic rays and cloud formation.
The authors also find a remarkable correlation between solar rotational signals, cloud height, and the Madden-Julian Oscillation [third figure below], which may represent yet another mechanism by which small changes in solar activity can be amplified to large changes in climate. Other amplification mechanisms include via ocean oscillations, ozone, and sunshine hours/clouds.
I have to say, Thank God for the good folks over at WUWT. Smart, intelligent,analytical, and skeptical people who simply follow the evidence to either prove or disprove a theory. Definitely, one of the best science sites out there.
I find it a bit concerning that apparently we’re in a negative solar magnetic cycle if I’m getting this right which is associated with cooler temps, along with the la nina run all combining for no warming. An el nino could give us a spike again it seems like. I believe we’re near the peak of a low sunspot cycle which could mean cooler temperatures again for several years more but after that the warmer positive cycle could be coming along with another sunspot/magnetic activity peak. Not that I don’t want warmer weather, but it doesn’t leave as much of a window for falsifying catastrophic AGW among reasonable people as I think I like.
