First you guys average the daily maximums and daily minimums to come up with the daily average.
Then the daily averages from the year winter and summer are taken to get the yearly average.
Then those yearly averages from across the globe tropics to the poles are averaged. Finally
all the years since 1850 are plotted out to show that the average global temperature increased
from 1850 to 1880, decreased from 1880 to 1910, increased from 1910 to 1945, decreased from
1945 to 1975 (the global cooling episode you guys deny), and increased since 1975 (which you
guys say is entirely due to CO2). After all that averaging it's an increase of about a degree
in over a century and a half. And you guys want me tochange my life style because of that.
From my file of tag lines and smart remarks, there's tha wonderful quote from
Dixie Lee Ray:
"Beware of averages. The average person has one breast and one testicle."
