Indicating intense magnetic activity, sunspots accompany secondary phenomena such as coronal loops, prominences, and reconnection events. Most solar flares and coronal mass ejections originate in magnetically active regions around visible sunspot groupings.
According to Danish scientist Henrik Svensmark, when there is less or fewer sunspots, the solar wind decreases. This allows cosmic rays from the overall universe to hit Earth's atmosphere and cause increased cloud formation, that reflects more sun off of the Earth.
which means a cooling effect? so, when the sun burns hotter, it gets cooler... does not make sense, unless your living depends on further study...
