The role of Sun in recent global warming and projections for its future influence in the context of man-made climate change has been analyzed. Energy receiving from Sun, in the form of electromagnetic radiation is the fundamental driver of the Earth’s climate system. The total solar energy hitting the Earth depend on its distance from the Sun and therefore on the ecliptically, but the distribution of the radiation over the globe depends on the tilt and precession. The amount of energy arriving in summer at high latitudes determines whether the winter growth of the ice cap will recede or wetter the climate will be precipitated in to an ice age. Thus change to seasonal irradiance. The total solar energy hitting the Earth depends on its distance from the Sun. The Sun has an effect on climate by its radiation and the main energy source of our Planet. Space weather may also in long term effect the Earth climate. Solar ultraviolet, visible and heat radiation are primary factor for Earth’s climate. Sunspots have been recorded through several hundreds of year and many scientists observed correlation between the solar magnetic activity, which reflected in the sunspot frequency, and climate parameter at Earth. 70-90 year oscillation in global mean temperature is correlated with corresponding oscillation in solar activity. The role of Sun also had been providing the Earth with energy for billions of years.
