Report Explodes Global-warming Alarmism — “Adjusted” Data Accounts for All the Hyped Temperatures

The New American
by William F. Jasper


A new blockbuster study that examines the most relied-upon global temperature data sets could start a chain-reaction demolition of global-warming alarmism. The peer-reviewed study by two climate scientists and a statistician challenges the “adjustment” process used to produce the global average temperature datasets (GAST) that have dominated media headlines and political debate for the past two decades. The new report could also upend the multi-billion dollar climate lobby, as well as the Obama administration’s EPA executive order declaring carbon dioxide to be a dangerous gas.

The new study, “On the Validity of NOAA, NASA and Hadley CRU Global Average Surface Temperature Data & The Validity of EPA’s CO2 Endangerment Finding,” co-authored by Drs. James P. Wallace III, Craig D. Idso, and Joseph S. D’Aleo, was released on June 27. It was peer-reviewed by a distinguished group of seven scientists, including Dr. Alan Carlin (retired senior analyst and manager, U.S. Environmental Protection Agency), Professor Anthony R. Lupo (expert reviewer for the UN’s Intergovernmental Panel on Climate Change), and Dr. George T. Wolff (former chair of the EPA’s Clean Air Scientific Advisory Committee).

The “conclusive findings” of their research, say the study co-authors are that inappropriate “adjustments” have been made to the temperature record, with the result that “the three GAST data sets are not a valid representation of reality.” “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.”

The researchers 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.” If the invalid GAST “adjustments” are discarded, there is virtually no warming trend to speak of. That, of course, is what the “pause” or “hiatus” in global temperatures of the past 20 years is all about. Despite the monkeying with GAST, even many of the top alarmists have admitted that the pause is real and that they have no satisfactory explanation for it.
