“Although the solar effect on the North Atlantic Oscillation explains only a few percent of the total variance, the close relationship between solar activity and phase North Atlantic Oscillation is an important indicator to improve the predictability of climate variability” say GEOMAR (press-release 15. Sept. 2015)

“Rising global temperatures since the industrial revolution cannot be attributed to increased solar activity”, reports Phys.org. (August 7, 2015); by concluding
“The apparent upward trend of solar activity between the 18th century and the late 20th century has now been identified as a major calibration error in the Group Sunspot Number. Now that this error has been corrected, solar activity appears to have remained relatively stable since the 1700s.”

It is time to put the sun in second or third position. There is no evidence that varying sun-ray has ever caused a significant and abrupt climatic change in many million years.
