One of the oddest aspects of climate “science” is that NASA, the organisation that put a man on the moon, ignores its state of the art Satellite and balloon data, and instead relies upon archaic terrestrial ground measurements.
Part of the NASA climate “science” community actually ignore the infinitely more accurate data from their satellites. The reason for this bizarre irony is obvious, the satellite data shows no non-El Nino warming since its inception in 1979.
The 13 month moving average in 2012 was the same as in 1980, and below the level reached in 1987.
Last month’s level was about the same as the peak level reached in 1983. Temperatures were essentially flat between 1980 and 1998, interrupted by a very strong El Nino, and then flat again from late 1998 and 2016, and then interrupted by another very strong El Nino.
