A new paper published by the Astronomical Society of Australia has a warning to global warming believers not immediately obvious from the summary: 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. Or as one of the authors, Ian Wilson, kindly explained to me: 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. Oh. Global cooling coming, then. Obvious, really.
