The best method for identification of planetary forcing of the Earth’s climate is to inves-tigate periodic variations in climate time series. Some natural frequencies in the Earth climate system seem to be synchronized to planetary cycles and amplified to a level of detection. The response by the Earth depends on location, and in a global…

A correlation is found between changes in Earth’s length of day [LOD] and the spatio–temporal disposition of the planetary masses in the solar system, characterised by the z axis displacement of the centre of mass of the solar system [CMSS] with respect to the solar equatorial plane smoothed over a bi-decadal period. To test whether…

A Venus–Earth–Jupiter spin–orbit coupling model is constructed from a combination of the Venus– Earth–Jupiter tidal-torquing model and the gear effect. The new model produces net tangen-tial torques that act upon the outer convective layers of the Sun with periodicities that match many of the long-term cycles that are found in the 10Be and 14C proxy…

Commensurabilities are calculated based on published orbital periods of planets and satellites. Examples are given for commensurabilities that are strong or very strong. There are sets of com-mensurabilities that involve 3–4 celestial bodies. Our moon–Earth system is probably a key system forming commensurabilities with all the inner planets. The existence and structure of commensurabilities indicate…

Herein we adopt a multiscale dynamical spectral analysis technique to compare and study the dynamical evolution of the harmonic components of the overlapping ACRIMSAT/ACRIM3 (Active Cavity Radiometer Irradiance Monitor Satellite/Active Cavity Radiometer Irradiance Monitor 3), SOHO/VIRGO (Solar and Heliopheric Observatory/Variability of solar Irradiance and Gravity Oscillations), and SORCE/TIM (Solar Radiation and Climate Experiment/Total Irradiance Mon-itor)…
