In this last Paper III additional evidences that the solar high energeticparticles radiation with energies higher as 100 MeV (the solar cosmic rays SCR)is an very important component for the "Sun- climate" relationship are given(see also Paper I and II). The total solar irradiance (TSI) and the galacticcosmic rays (GCR) variations given an integral climate effect of cooling insunspot minima and warming in the sunspot maxima. Unlike the both ones thepowerful solar corpuscular events plays a cooling climate role during theepochs of their heigh levels. By this one subcenturial global and regionaltemperature quasi- cyclic changes by duration of approximately 60 years couldbe track during the last 150 years of instrumental climate observations . Ithas been also evided in the paper that this subcenturial oscilation is veryimportant in the Group sunspot number (GSN) data series since the Maunderminimum up to the end of 20th century. Thus the solar erruptive activity effectmake the total "Sun -climate" relationship essentially more complicated as itcould be follow when only the TSI and GCR variations are taken into account. Inthis light the climate warming tendency after AD 1975 is rather by a natural asby an antropogenic origin. Most probably the last one is very close related tothe general downward tendency of erruptive solar events which is superimposedover the high long term TSI levels during the last three decades (AD1975-2007). It is evided, that the efficiency of the solar corpuscular activutyover the climate is strongly depended by the "north-south" asymmetry of thesolar activity centers (as a proxy the sunspots area north-south asymmetryindex A is used there). The climate cooling effect in the Northern hemisphereis most powerful during the epochs of positive values of A.
