Thanks for the stats. What's the 194.8% a percentage of? If you're just
dividing one temperature in degrees Celsius by another (the long-term
mean), then I'd argue that it isn't very meaningful, as by making 0C the
baseline it gives it a spurious significance. It's not like rainfall or
sunshine, where zero really is the lowest value possible.
