.If there are any politically uncompromised climate scientists left in the world, this should kill off the whole global warming fraud. Dr. Edward R. Long has recently compared rural temperatures with urban temperatures, both as raw data and as they are adjusted by the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center (NCDC).
Here is what he found:
The raw data shows very little warming in rural areas and signifcant warming in urban areas (i.e. cities). But the NCDC adjustments "fix" the rural data to be like the urban data, thus making it look like there is global warming, when actually the warming only exists in areas with hot pavement and buildings. There is no explanation for why NOAA/NCDC would do such a thing. They have always claimed that their adjustments reduce the urban heat island effect, but it turns out they actually do the opposite.

Combined with similar studies showing such upward adjustments also exist in world-wide data, this exposes a pervasive bias in temperature measurements. Most of the other world datasets such as NASA-GISS's GISTEMP, use the NCDC data as a starting point and then add their own upward biases.
The full paper may be found here: Contiguous U.S. Temperature Trends Using NCDC Raw and Adjusted Data for One-Per-State Rural and Urban Station Sets (PDF) and is freely available for viewing and distribution. Dr. Long also recently wrote a column for The American Thinker titled: A Pending American Temperaturegate. As he points out in that column, Joe D’Aleo and Anthony Watts raised similar concerns in: Surface Temperature Records: Policy Driven Deception? (PDF)
