The latest effort at analyzing the adjustments comes from a team of independent researchers led by James Wallace, and including Joseph D'Aleo and Craig Idso. Their new Research Report can be found at this link, titled "On the Validity of NOAA, NASA and Hadley CRU Global Average Surface Temperature [GAST] Data & The Validity of EPA’s CO2 Endangerment Finding." The new Research Report has seven highly qualified peer reviewers identified in the paper itself. From the Abstract:

In this research report, the most important surface data adjustment issues are identified and past changes in the previously reported historical data are quantified. It was found that each new version of GAST has nearly always exhibited a steeper warming linear trend over its entire history. And, it was nearly always accomplished by systematically removing the previously existing cyclical temperature pattern. This was true for all three entities providing GAST data measurement, NOAA, NASA and Hadley CRU
