According to the National Oceanic and Atmospheric Administration (NOAA), March of this year was the hottest March since record-keeping began in 1880, and 2014 was "the hottest year ever."
NOAA's figures were based on data compiled from a network of weather stations by NOAA's Global Historical Climatology Network (GHCN).
But two other officially recognized entities measuring temperatures, Remote Sensing Systems and the University of Alabama, are based on a different method of measuring, by satellite. And these "give a strikingly different picture," Christopher Booker discloses in The Telegraph.
"Neither shows [March] as anything like the hottest March on record, any more than they showed 2014 as 'the hottest year ever.'"
According to Booker, analysts have found hundreds of examples of how the data recorded by some 3,000 weather stations in the GHCN have been "adjusted" to exaggerate how much the planet has actually been warming.
Figures from earlier decades have frequently been adjusted downward and more recent data adjusted upward to show the Earth having warmed much more dramatically than the original data indicated, he explained.
Now the Global Warming Policy Foundation has assembled an international team of five top scientists to determine how these "adjustments" of data may have distorted what is in fact happening to global temperatures.[...]
The five are Dr. Petr Chylek, a physicist from the National Los Alamos Laboratory; Richard McNider, founder of the Atmospheric Sciences Program at the University of Alabama in Huntsville; Prof. Roman Mureika, a statistics expert from Canada; Prof. Roger Pielke Sr., a noted climatologist from the University of Colorado; and Prof. William van Wijngaarden, a physicist at York University in Canada with many papers on climatology.
The team is led by Terence Kealey, until recently the vice-chancellor of the University of Buckingham in Britain.
Their goal is to establish to what extent original data has been "adjusted" by the three main keepers of surface records: the Goddard Institute for Space Studies, the U.S. National Climate Data Center, and the Climatic Research Unit of the University of East Anglia in Britain in conjunction with the Hadley Centre for Climate Prediction and Research.
"All three of them are run by committed believers in man-made global warming," Booker notes.
"Only when the full picture is in will it be possible to see just how far the scare over global warming has been driven by manipulation of figures accepted as reliable by the politicians who shape our energy policy."
