The Sun rotation around the center of mass of the Solar System is considered as a possible factor of climate fluctuations. Earth follows the Sun in its barycentric motion. It is proposed to evaluate the dynamic effect of this movement on the oscillatory climate system by cyclic changes in the moment of inertia of the barycentric movement of the Sun–Earth pair. Based on the known coordinates of the orbital motion of the giant planets, the annual values of the moment of inertia of the Sun’s motion around the center of mass of the Solar System for 1800–2050 are obtained. We used data on the average annual surface temperature of the oceans at the nodes of the geographic grid of the Earth for 1960–2018. By the method of asynchronous correlation analysis, high significant correlations were found between the moment of inertia of the barycentric movement of the Sun–Earth pair and changes in the average annual temperature of the surface of the World Ocean in places of major ocean currents with a temperature delay of 32–37 years. The best positive correlation coefficients (from 0.4 to 0.7) were observed along the trajectories of cold currents—circumpolar Antarctic current, Peruvian and California currents, and negative (from –0.4 to –0.7) were found in warm currents—East Australian, Kuroshio, North Atlantic, Norwegian. Surface changes in temperature turned out to be most significant at the places where ocean currents cross underwater obstacles (underwater ridges and uplifts of the bottom of the oceans). The contribution of the changes in the motion of the Sun–Earth pair around the center of mass of the Solar System to changes in the temperature of the ocean surface in different parts of the World Ocean comprised from 25 to 50% of its total variability. It is assumed that cyclic changes in the moment of inertia can resonantly affect on the climatic oscillatory system on natural frequencies of climatic system close to the frequencies of external influences.
