Does sunspots effect the earth and us?
Yes, but indirectly. Sunspots do not affect most of the energy that the sun radiates to the earth, that is, the sunlight we see. Fortunately for us, this radiation does not change much. However, the number of sunspots is an indication of the general level of magnetic activity on the sun. This affects other radiations from the sun that we cannot see without special sensors. These radiations can vary a lot. The effects of these radiations on the upper atmosphere, the earth’s ionosphere and space around the earth are called space weather. As human activities become more complex and depend more on communications and accurate navigation, space weather will more and more affect our activities on earth. Dr.
