A recently-retired top scientist from the America’s National Oceanic and Atmospheric Administration (NOAA) has accused his superiors of fudging data to hide a slowdown in the rise of global temperatures ahead of the UN Climate Change Conference in 2015.
John Bates told the Mail on Sunday that Thomas Karl, the head of the climate change department at the government agency, authored a paper based on doctored data, “rushed” it into publication, and then saw his work used to make international commitments to fight global warming worth hundreds of billions of dollars.

After rising by 0.113C per decade between 1950 and 1999, temperatures appeared to have stabilized between 2000 and 2014, despite rising levels of CO2 emissions, which climate change scientists said were responsible for the earlier warming.
The “pause,” unveiled in a 2012 UN report, shook up the entire scientific community, and cast doubt upon hundreds of models confidently predicting a trend of accelerating warming.

But then, Karl’s “pausebuster” paper emerged, just months before Barack Obama, Angela Merkel and scores of other world leaders congregated in Paris, showing that global warming was not slowing down, but actually accelerating to 0.116C per decade.
Bates said that in the period preceding the publication, Karl was “insisting on decisions and scientific choices that maximized warming and minimized documentation… in an effort to discredit the notion of a global warming pause, rushed so that he could time publication to influence national and international deliberations on climate policy.”
Bates claims that the land temperature readings cited in the study were calculated using two combined historical records, with the help of an unfinished and buggy piece of software, whose findings cannot be independently verified, and have still not been confirmed by the authors. For the sea temperature records, Karl decided to use temperatures collected by ships.
“They had good data from buoys. And they threw it out and ‘corrected’ it by using the bad data from ships. You never change good data to agree with bad, but that’s what they did – so as to make it look as if the sea was warmer,” said the scientist.
