AB: Empirical evidences of the relationship that does exist between solar activity, Earth rotation rate and global surface temperature long-term modulations and the mechanisms able to explain such a relationship are reviewed. In particular we discuss the possibility that these modulations are excited either externally by planetary spin-orbit interaction, or internally to the sun , so controlling the intensity and frequency of geomagnetic storm time variations that in turn excite length of day and secular geomagnetic variations by electromagnetic induction.
