The study is very interesting and it is a plausible explanation. The correlation is there and the reasoning seems fairly tight.<br/><br/>Another thing to look at are variations in the Earth magnetic fields. It reverses periodically and when it does we are particularly susceptible to cosmic rays which are nasty fellows. I am a physicist. The study is very interesting and it is a plausible explanation.
