It's out! The new Anthony Watts paper on biased surface temperature measurements

Which, inter alia, puts a bomb under the Muller global warming claims also just published

For a private person to undertake almost single-handed such a big task as collating data from all U.S. temperature-measuring stations is a Herculean effort but Watts and his helpers have done so. There are great bureaucracies devoted to the task elsewhere.

What he has done is to show that a more rigorous measure of the urban heat island effect -- a measurement method embraced by the World Meteorological Organization -- greatly alters the resultant findings. And after that essential adjustment, the 1979-2008 U.S. temperature rise is much REDUCED, halved, in fact.

Its rather a disgrace that the official meteorological organizations have not applied the more rigorous method but they would have seen very early on that doing so would have dynamited their Warmist beliefs. Ideology trumps facts.

Below are three conclusions about the adjusted data used by Muller which I particularly like:

* Poorly sited station trends are adjusted sharply upward, and well sited stations are adjusted upward to match the already-adjusted poor stations.

* Well sited rural stations show a warming nearly three times greater after NOAA adjustment is applied.

* Urban sites warm more rapidly than semi-urban sites, which in turn warm more rapidly than rural sites.

In short, the tiny amount of global warming claimed by the Warmists gets even tinier if you bypass the conventional adjustments. Putting it another way, most of the claimed global warming is an artifact of the analytical method. It is not there in reality.

A quote from Watts about the Muller research: "“I fully accept the previous findings of these papers, including that of the Muller et al 2012 paper. These investigators found exactly what would be expected given the siting metadata they had."

In other words, the Muller paper found what it did only because of the poor data that the authors used.
