QUOTE: "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."


A new paper entitled: Does a Spin-Orbit Coupling Between the Sun and the Jovian Planets Govern the Solar Cycle? by Wilson et al has been published.

The Abstract states:
We present evidence to show that changes in the Sun's equatorial rotation rate are synchronized with changes in its orbital motion about the barycentre of the Solar System. We propose that this synchronization is indicative of a spin-orbit coupling mechanism operating between the Jovian planets and the Sun. However, we are unable to suggest a plausible underlying physical cause for the coupling. Some researchers have proposed that it is the period of the meridional flow in the convective zone of the Sun that controls both the duration and strength of the Solar cycle. We postulate that the overall period of the meridional flow is set by the level of disruption to the flow that is caused by changes in Sun's equatorial rotation speed. 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.

Andrew Bolt contacted lead author Ian Wilson who told him:

"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."

Hey, Alarmist, leave them kids alone! All in all it's just another brick in the wall All in all it was just another brick in AGWs ruines

May I use that ? It's YOUR copyright after all.

Peter Muehlbauer don't need no education, and if no education is good enough for him, then no education is good enough for you.
