NCDC has no thermometers in most of Africa, and nearly half of the rest of the land surface, so they fabricate fake land temperatures based on sea surface temperatures more than 1,000 km away
To show how fraudulent this practice is, let’s look at the US where they do have surface data. The Atlantic was warm, while the US and Canada were very cold last year. You can not extrapolate temperatures across land/ocean boundaries.
What they are doing is equivalent to measuring Death Valley temperature, based on the temperature of the cold water offshore in the Pacific.
But it gets worse – after making up these completely fake temperatures across vast swaths of the planet, they report a global temperature record of 0.02 degrees. This is scientific malfeasance – pure and simple.
