Empirical evidence for a celestial origin of the climate oscillations and its implications

TL;DR

This study provides empirical evidence linking celestial cycles, such as planetary and solar oscillations, to climate variability and suggests that natural astronomical factors significantly influence recent climate change.

Contribution

It identifies specific astronomical cycles correlated with climate oscillations and develops a phenomenological model to reconstruct and partially forecast climate patterns since 1850.

Findings

Climate oscillations align with planetary and solar cycles.

At least 60% of warming since 1970 attributed to natural cycles.

Forecast suggests potential stabilization or cooling until 2030-2040.

Abstract

We investigate whether or not the decadal and multi-decadal climate oscillations have an astronomical origin. Several global surface temperature records since 1850 and records deduced from the orbits of the planets present very similar power spectra. Eleven frequencies with period between 5 and 100 years closely correspond in the two records. Among them, large climate oscillations with peak-to-trough amplitude of about 0.1 $^oC$ and 0.25 $^oC$, and periods of about 20 and 60 years, 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 21$^{st}$ century. 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.
