As the sunspots are dark and cooler spots on the surface of the sun and they are formed due to a cycle of 11 years and don't directly impact the long term climate cycle of the onset earth as the rise and fall in the sea levels and the movement of the ice sheets and the tectonic upliftment are not caused by them and thus they are not responsible for the climatic changes on earth.
<u>Sun energy is needed d to keep the net active and with the presence of the sun the earth world has temperature extremes and no rotational motion thus long term climatic patterns are dependent on the planet's internal framework.</u>
