On a related topic, I'd love for weather services to start the practice
of fixing their average temps to a pre-YYYY figure, say 1990.
These dramatic warm years are dragging the average temps up, hiding some
of the extremeness of the changes.
The above chart would probably be even more astounding (or whatever is the
proper adjective) if the current temps were plotted against pre-1990
averages.
Quick followup on the logic therein--average temps, readings,etc. are
helpful when you are in a fixed climatic regime -- when the regime is
changing those averages become a lot less helpful for understanding how the
instantaneous weather fits in.
Given the assumption of a changing climate, better charting would somehow
give people a sense of the rate of change (not sure the best way to do
that--any ideas?)
