This paper explores the links between terrestrial temperature, sea levels and ice areas in both hemispheres with solar activity in- dices expressed through averaged sunspot numbers together with the summary curve of eigen vectors of the solar background magnetic field (SBMF) and with changes of Sun-Earth distances caused by solar inertial motion resulting from the gravitation of large planets in the solar system. Using the wavelet analy- sis of the GLB and HadCRUTS datasets two periods: 21.4 and 36 years in GLB, set and the period of about 19.6 years in the HadCRUTS are discovered. The 21.4 year period is as- sociated with variations in solar activity defined by the sum- mary curve of the largest eigen vectors of the SBMF. A dom- inant 21.4-year period is also reported in the variations of the sea level, which is linked with the period of 21.4 years de- tected in the GLB temperature and the summary curve of the SBMF variations. The wavelet analysis of ice and snow ar- eas shows that in the Southern hemisphere it does not show any links to solar activity periods while in the Northern hemi- sphere the ice area reveals a period of 10.7 years equal to a usual solar acitviity cycle. The TSI in March-August of every year is found to grow with every year following closely the tem- perature curve, because the Sun moves closer to the Earth or- bit owing to gravitation of large planets. (solar inertial mo- tion, SIM). While the variations of solar radiation during a whole year have more steady distribution without a sharp TSI in- crease during the last two centuries. The additional TSI con- tribution caused by SIM is likely to secure the additional energy input and exchange between the ocean and atmosphere.
