The sun goes in a 11 year sunspot cycle & we are now on cycle 24 (since records begun). The more active the sun the more sunspots and solar flares appear. A hibernation of sunspot activites could bring colder & more unstabled weather on Earth. There is record of this sometime around the 1600s when sunspot activity was very low. Also without high sunspot activity during the 11 year solar cycles, High Frequency (HF, shortwave radio propagation) that relies on refraction from the ionosphere's (F1 & F2 layer) for Worldwide communications, would be poor.
