Surface temperature data are more wild guesses than actual thermometer measurements ---- but government bureaucrats say they are "good enough for government work" !

There are 2,592 feasible 

5 degree longitude by

5 degree latitude

"grids" (boxes)

making up the

surface of the Earth.

Prior to World War II, 

there were less than 

600 boxes 

covered with 

a “mean value” (23%) 

with about 200 boxes 

covered with

a “max-min” value (8%).

That means no data at all 

for 69% of the planet's surface

-- numbers for those grids

had to be wild guesses

by government bureaucrats

with science degrees,

to compile a global surface

temperature average.

That's a lot of wild guessing !

But good enough 

for government use,

I suppose !

US stations are 

supposed to be

the best in the world 

but Anthony Watt’s 

showed us that

only 7.9% of them 

achieve better than 

a 1°C accuracy.

There are virtually no 
weather stations 
with thermometers
for:

20% of the land surface 
   that are mountains,

20% of the land surface 
   that is forest,

19% of the land surface 
   that is desert and,

19% of the land surface 
   that is grassland.

The result is an inadequate

surface temperature record.

There have been 

weather balloons

since the 1950s, 

and weather satellites

since 1979.

Their temperature 

measurements

are very similar.

But they both show 

less global warming

than surface measurements, 

with all their infilling 

(wild guessing),

... so they are ignored.

Only the outlier 

of the three measurement

methodologies is used

by government bureaucrats

-- surface temperature data.

I'm very confident,

almost 100% sure,

that weather 

satellite data

would be used,

and surface data

would be ignored,

if the satellite data

showed more warming

than the surface data !
