A study has revealed that scientists have been making adjustments to global surface temperature readings in order to make them appear warmer than reality. The study founds that scientists are making temperature readings which “are totally inconsistent with published and credible U.S. and other temperature data.”
The peer-reviewed study by two scientists and a statistician looked at surface temperature data taken by NASA, NOAA and the UK’s Met Office, which all adjust their thermometer readings to account for “biases” in the information. The new study was attempting to validate these findings and didn’t actually criticize data adjustment, but did note that it contributes to increased findings of global warming trends.
“Thus, it is impossible to conclude from the three published [global average surface temperature (GAST)] data sets that recent years have been the warmest ever – despite current claims of record setting warming,” found the study.
“The conclusive findings of this research are that the three [global average surface temperature] data sets are not a valid representation of reality,” the study says. “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.”

In fact, almost all the surface temperature warming adjustments cool past temperatures and warm more current records, increasing the warming trend, according to the study’s authors.
“Nearly all of the warming they are now showing are in the adjustments,” Meteorologist Joe D’Aleo, a study co-author, told The Daily Caller News Foundation in an interview. “Each dataset pushed down the 1940s warming and pushed up the current warming.”
“You would think that when you make adjustments you’d sometimes get warming and sometimes get cooling. That’s almost never happened,” said D’Aleo, who co-authored the study with statistician James Wallace and Cato Institute climate scientist Craig Idso.
