The Sun reached what should have been the apex of its solar activity cycle back in mid-2000. Truly, it has continued on with unusual activity since that time. It has been proved that planetary alignments to the closest and farthest distances planets make to the Sun (perihelia and aphelia) and to planetary nodes stimulate solar activity. Such alignments have been in place since 2000 permitting the wild ejections from the Sun - Coronal Mass Ejections - to persist.
The CME's do affect behavior cycles in people. The feeling during a CME blast is that of body and mind not being synchronized. The effect creates a slight sense of anxiety and can produce the physical symptoms of increased heart rate and respiration. The classic response is a reduction of coping skills.
Some have recently claimed that solar activity caused geologic shifts thousands of years ago. This cannot accurately be stated. Sunspots have been monitored only since the 1600's. True, geologic shifts can be found in soil and rock composition layers. It, however, cannot be stated with certainty that these shifts relate to solar cycles.
Even so, will a solar outburst end the world? Not in the traditional CME category. Something far more catastrophic would have to happen to our Sun. There is no astronomical reason to suspect the Sun is about to run amuck. But CME's do have a substantial effect on the atmosphere, jet stream and subsequently, stimulate anomalistic weather patterns. As noted before, the energy system of individuals can be affected. The more sensitive you are, the more these outbursts will impact you. Despite having an out of sorts day during these emanations, the world does not end.
