In your own words explain how the number of sunspots can affect the overall global climate on earth

The sun has the largest effect on the climate that we enjoy on earth. without it there would be no light, resulting in no growth, since our climate largely relies on the sun to provide the energy needed for photosynthesis. sunspots were first noticed to affect the earth when scientists realized that increased activity with sunspots creates increased interference with magnetic instruments on the surface of the earth. the first most noticeable effect of sunspots on our climate were the northern and southern lights, otherwise known as the aurora. with sunspots come an increase in ultraviolet rays that emit from the outer ring of the sunspots toward earth. this increase in uv rays affects chemistry of the outer atmosphere and the energy balance of earth. the idea that sunspots affect earth's climate is still largely debated, but it is believed that the increase of sunspots on the surface of the sun can reduce the amount of energy and light distributed to earth. this decrease in energy can result in colder weather and even "mini ice ages" on parts of earth . however, sunspots affect life on earth through the borealis and the aurora australis. the magnetic field that is projected from solar flares is much more powerful than the magnetic field that protects earth, which creates a magnetic storm seen by the colors in the sky during these two events. these magnetic fields can also disrupt power grids and radio signals on earth and the satellites that orbit earth.
