    Sigma balls. Am I doing this right?


    For seriously though, its explained in the article:

    For those of you who are interested in statistics, this is a five-sigma event. So it’s five standard deviations beyond the mean. Which means that if nothing had changed, we’d expect to see a winter like this about once every 7.5 million years.
