Sunspot activity is a cycle that cycles about every 11 years. Sunspots are indicative of increased cosmic radiation and since 2000 (the last peak) has been steadily declining. It is now at the low point in the cycle, and from now, for the next 11 years it will increase.

This is normal, nothing to get excited about, except that sunspot activity increases may affect both climate change and it is also possible that with the world now far more reliable on microwave communications, cell phones, etc. that we will experience increasing interference. Since the cell phone revolution’s real growth has occurred in the past 10 years, if cosmic radiation becomes a factor, it could spell times when communications are disrupted. Business reliance on text messaging and other infrastructure issues are not going to cause a disaster, but may be more expensive to tax payers ultimately.
