From Watts Up With That:
It’s true, and it’s huge. Today another example of CRU having their foot on the scale, Russian papers are reporting that the Russian surface station data was sorted by CRU to use the highest warming stations only.
Analysts say Russian meteorological stations cover most of the country’s territory, and that the Hadley Center had used data submitted by only 25% of such stations in its reports.
Over 40% of Russian territory was not included in global-temperature calculations for some other reasons, rather than the lack of meteorological stations and observations.
The data of stations located in areas not listed in the Hadley Climate Research Unit Temperature UK (HadCRUT) survey often does not show any substantial warming in the late 20th century and the early 21st century.
They specifically state that lack of measurement is not the cause. If they claim the full set of Russian data does NOT support global warming, imagine how different the bright red dot over Russia would look. Again the accusation is completely believable, yet is completely unverifiable because CRU has refused to release the data. This data and code release is the subject of illegal blocking of FOIA’s is one of the keys in the Climategate emails. We need to know the list of stations used and we must have copies of the raw data.
This is a very powerful accusation, which if true could change much about the climate science debate. Many papers are based on this dataset which has the highest trend of the major ground datasets.
