The sun is the source of the energy that drives the biological and physical processes in the world around us and in the atmosphere, it warms air which drives our weather. The rate of energy coming from the sun changes slightly day to day. Over many millennia in the Earth-Sun orbital relationship can change the geographical distribution of the sun’s energy over the Earth’s surface. It is found that changes in solar output might affect our climate both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes. Solar influence has been a significant driver of global temperature change over several decades. We found that the sunspot activities are more responsible to increase the temperature of the climate.
