Sunspots Declining

According to the American Astronomical Society, sunspots are making fewer appearances than expected these days. This -- along with weaker magnetic activity near the sun's poles -- could be a sign that a solar minimum is on the way. The sun normally goes through an 11-year cycle of increased and decreased activity. At this time, the sun is heading towards the maximum of activity in this cycle. But sun spots have not been increasing at their normal rate. This could have a cooling effect on the earth's climate in the long run. See full article here.
