“Welcome to the Adjustocene.”
A new peer-reviewed study claims that “nearly all” of the warming shown in current temperature datasets is the result of adjustments made after the temperatures were recorded.
The adjusted datasets, from NASA, NOAA and the Met Office in the United Kingdom, call into question just how much warming is real and how much is pure fantasy.
In the report, entitled “On the Validity of NOAA, NASA and Hadley CRU Global Average Surface Temperature Data and the Validity of EPA’s CO2 Endangerment Finding,” authors James P. Wallace III, Joseph S. D’Aleo and Craig Idso examine the accuracy of Global Average Surface Temperature (GAST) data.
It urns out that GAST data is not simply the raw temperature recordings. Rather, the data is adjusted after it is recorded to account for various problems, such as “contamination by urbanization.”
Critics (myself included) think these adjustments have been exaggerated to favor the view humans are causing climate change.
To test the validity of the GAST data adjustments, the two scientists and veteran statistician examined other historical data to determine whether the adjustments were appropriate.
“The three GAST data sets are not a valid representation of reality,” the authors wrote. “In fact, the magnitude of their historical data adjustments, that removed their cyclical temperature patterns, are totally inconsistent with published and credible U.S. and other temperature data. Thus, it is impossible to conclude from the three published GAST data sets that recent years have been the warmest ever — despite current claims of record setting warming.”
“Nearly all of the warming they are now showing are in the adjustments,” meteorologist Joe D’Aleo, who co-authored the study, said to the Daily Caller News Foundation. “Each dataset pushed down the 1940s warming and pushed up the current warming.”
The researchers’ findings could totally dismantle the claim humans are causing global warming
