Yes Merv - your hurricanes have so far been rather more notable than our storms!
But didn't I read recently of an attempt to lower the "signifcant" level of standard deviations amongst some reseachers (not climate change, as far as I know), in order to weed out unrepeatable science?
That reminds us that it's still a matter of judgement when a series is "significant". Local variations can be highly skewed, such as a run of 100 coin tosses in a row happening by chance at some rare level. In the extreme it's been said that, given an infinite and eternal multiverse, the repeatability of the strictest scientific laws might not just be a chance feature of our particular universe, but an entirely aberrant run of coincidences - tomorrow, things might suddenly start falling up or down in some random sequence, revealing the norm for the first time in (astronomically short) history.
That's what comes of the doctrine of chance if one isn't careful! In your example, the chances are that 50 heads in 100 coin tosses ispretty unlikely to happen by chance anyway!
