Thanks for the link from Joe Bast. Many years ago I told Roy Spencer he and the UAB satellite info would become more and more important because it was more global, and less likely to be screwed with by the politically motivated warmers. Siting, sifting and culling reporting stations, smoothing the record adjusting the record–now this–NOAA just “adjusts” away the surface data and cheats for their version of the story and enviro justice.
NOAA Fiddles With Climate Data To Erase The 15-Year Global Warming ‘Hiatus’

NOAA’s updated data was also criticized by climate scientists with the libertarian Cato Institute. Scientists Richard Lindzen, Patrick Michaels and Chip Knappenberger argue the adjustments made by NOAA were “guaranteed to put a warming trend in recent data.”
Cato scientists also argued that NOAA’s new data is an outlier compared to other global temperature records, which overwhelmingly show a hiatus in warming.
It “would seem more logical to seriously question the [NOAA] result in light of the fact that, compared to those bulk temperatures, it is an outlier, showing a recent warming trend that is not in these other global records,” the three scientists wrote.
“Adjusting good data upwards to match bad data seems questionable, and the fact that the buoy network becomes increasingly dense in the last two decades means that this adjustment must put a warming trend in the data,” wrote Michaels, Knappenberger and Lindzen, who is a top climatologist from the Massachusetts Institute of Technology.
Scientists and climate experts skeptical of man-made global warming have become increasingly critical of temperature adjustments made by government climate agencies like NASA and NOAA. Skeptics charge that agencies like NOAA have been tampering with past temperatures to make the warming trend look much more severe than is shown in the raw data.
“It is important to recognize that the central issue of human-caused climate change is not a question of whether it is warming or not, but rather a question of how much,” they wrote. “And to this relevant question, the answer has been, and remains, that the warming is taking place at a much slower rate than is being projected.”
Georgia Tech climate scientist Judith Curry also chimed in, arguing that NOAA excluded extremely accurate sea buoy data in order to erase the hiatus in warming. Curry wrote that it “seems rather ironic, since this is the period where there is the greatest coverage of data with the highest quality of measurements — ARGO buoys and satellites don’t show a warming trend.”
“Nevertheless, the NOAA team finds a substantial increase in the ocean surface temperature anomaly trend since 1998,” she wrote. “This short paper in Science is not adequate to explain and explore the very large changes that have been made to the NOAA data set. The global surface temperature datasets are clearly a moving target. So while I’m sure this latest analysis from NOAA will be regarded as politically useful for the Obama administration, I don’t regard it as a particularly useful contribution to our scientific understanding of what is going on.”
