Trevor, and others if I've missed any, thank you very much for your
statistical anaysis, it's much appreciated.

It will be interesting to see how the rest of December turns out, and
whether it will go down in history as truely expectional, or just a
cold one.

Pleasure. I see CET has now soared to -1.7C, which is -6.67 from the
mean, giving a z-score of 4.5, which is enormous - about once in every
100,000 years. That is historic. December 1890 had z-score of 3.8, and
is the one to beat.

The question is how much will it warm up before it turns really cold
again (assuming the current models are correct).
