More than half of surface temperature "data" are wild guessed numbers -- just made up by bureaucrats -- and they have the nerve to claim record heat in "grids" where they make up the numbers ! ( our current wild guess is warmer than our previous wild guess ! ) ... This is junk science.

The NOAA chart below 
shows only the grids that include land.

The gray areas 
have no thermometers,
or are missing data,
so the grid average
is a wild guess
by government bureaucrats.

And there's a lot of gray 
in that land-only chart below !
