USHCN raw station data shows an average of 7 degrees/century cooling since 1998, while their fabricated (infilled) data shows almost no cooling. The fabricated data is data which has no underlying station data, and is manufactured by NOAA.
The next graph shows the divergence between the fabricated data, and the actual measured data. They are diverging at 6.5 degrees/century
Astonishingly, a number of well known scientists have been interviewed by the press saying that this is all good, and that my complaints should be ignored.
It defies explanation that USHCN would do this, and even more astonishing that anyone defends this practice of data tampering which destroys any meaning in the temperature record, and makes it both useless and destructive to science.
