Loogy, you said it all right below:
An average is an average.
We all agree with that statement. The question revolves about the title you
give your average. Apparently that's a point you're not grasping well.
If I take the average of the noon temperature in Seattle (50F)and the 3:00
PM temperature in Washington, DC (64F}, I can then say the average of the
two temperatures at the same time was 57F. If I wanted to be bold, I could
say that the average temperature across the continental US was 57F.
Hopefully, we can both see the stupidity of that 'boldness'.

"All decisions are the result of binary thinking."
It is what it is. An average. Given enough data sets it gets quite
accurate.
Again, the line above says it all. There have to be 'enough' data sets,
read at the same times, not influenced by man-made structures, etc, etc, in
order to say that the 'average temperature of the earth' is doing anything.
If you said, "The average temperature of these 1279 thermometers read at
1200 hrs, GMT was X," then you'd get no argument. You could make all the
claims you wanted about the 'average temperature of the 1279'!
