History of global warming theory

Multiple U.S. government bureaucracies including NOAA, NASA, and the Department of Energy are again being accused of inappropriately manipulating temperature data — or “adjusting” it, as officials at the agencies implicated in the scandal put it — to show global warming. While the accusations are not new, the latest scandal, sparked by an in-depth analysis of the data by independent analyst Steven Goddard at Real Science, relies on official records to suggest that federal agencies have been fudging temperature measurements to make past decades seem colder and recent years appear warmer.

Numerous scientists and experts confirmed Goddard’s explosive findings, but in separate responses to The New American, both NOAA and NASA attempted to downplay the significance of the accusations. The major problems identified by Goddard in the temperature records of federal bureaucracies relate to the U.S. Historical Climatology Network (USHCN), the official data-set covering the continental United States. While the agencies admit the records are adjusted, Goddard and multiple scientists suggested that biased methodology was used to adjust the data to show an unjustified and “spurious” warming trend.

“Bottom line is there is clearly a huge error in the USHCN adjustments which has added a non-existent one degree hockey stick warming to the official US temperature record, and I now know just where to look for it in their code, ” Goddard wrote. “NOAA made a big deal about 2012 blowing away all temperature records, but the temperature they reported is the result of a huge error. This affects all NOAA and NASA U.S. temperature graphs, and is part of the cause of this famous shift.” Citing satellite data, Goddard also said that by 2008, U.S. temperatures had cooled down below 1980s and 90s levels.
