A new paper published by the Astronomical Society of Australia titled:
contains a warning about earthly climate change not immediately obvious from the abstract:
Based on our claim that changes in the Sun’s equatorial rotation rate are synchronized with changes in the Sun’s orbital motion about the barycentre, we propose that the mean period for the Sun’s meridional flow is set by a Synodic resonance between the flow period (~22.3 yr), the overall 178.7-yr repetition period for the solar orbital motion, and the 19.86-yr synodic period of Jupiter and Saturn.
According to an interview with Andrew Bolt, of the Australian Newspaper, Herald Sun, Ian Wilson, one of the authors explained:
It supports the contention that the level of activity on the Sun will significantly diminish sometime in the next decade and remain low for about 20 – 30 years. On each occasion that the Sun has done this in the past the World’s mean temperature has dropped by ~ 1 – 2 C.
Hmmm, I’m not sold on this idea. This is a lot like what Dr. Theodor Landscheidt proposes. I have a little bit of trouble understanding how the “mass at a distance” gravitational effects of Jupiter and Saturn could have much effect on the solar dynamo.
I’m sure both my readers, and Dr. Leif Svalgaard, who regularly monitors this blog, will have something to add to provide additional insight. – Anthony
