Brilliant New Science – Planetary Orbits

Farmers and others who depend on climate will be very excited by the prospect of much more accurate predictions based on planetary cycles.
Or they would.
If it hadn’t already been decided by the so-called intellegencia what the future climate will be – Anthropogenic Climate Change doom – end of story.

Scafetta on 60 year climate oscillations

“George Taylor, former Oregon State climatologist writes:
Nicola Scafetta has published the most decisive indictment of GCM’s I’ve ever read in the Journal of Atmospheric and Solar-Terrestrial Physics.  His analysis is purely phenomenological, but he claims that over half of the warming observed since 1975 can be tied to 20 and 60-year climate oscillations driven by the 12 and 30-year orbital periods of Jupiter and Saturn, through their gravitational influence on the Sun, which in turn modulates cosmic radiation.
If he’s correct, then all GCM’s are massively in error because they fail to show any of the observed oscillations.
There have been many articles over the years which indicated that there were 60-year cycles in the climate, but this is the first one I’ve seen which ties them to planetary orbits.”

We investigate whether or not the decadal and multi-decadal climate oscillations have an astronomical origin. Several global surface temperature records since1850 and records deduced from the orbits of the planets present very similar power spectra. Eleven frequencies with period between 5 and100 years closely correspond in the two records. Among them, large climate oscillations with peak-to-trough amplitude of about 0.1and0.251C, and periods of about 20 and 60years, respectively, are synchronized to the orbital periods of Jupiter and Saturn. Schwabe and Hale solar cycles are also visible in the temperature records. A 9.1-year cycle is synchronized to the Moon’s orbital cycles. A phenomenological model based on these astronomical cycles can be used to well reconstruct the temperature oscillations since 1850 and to make partial forecasts for the 21stcentury.
It is found that at least 60% of the global warming observed since 1970 has been induced by the combined effect of the above natural climate oscillations. The partial forecast indicates that climate may stabilize or cool until 2030–2040. Possible physical mechanisms are qualitatively discussed with an emphasis on the phenomenon of collective synchronization of coupled oscillators.
