From the story here:
But the whistleblower, Dr John Bates, a top NOAA scientist with an impeccable reputation, has shown The Mail on Sunday irrefutable evidence that the paper was based on misleading, ‘unverified’ data. ... In an exclusive interview, Dr Bates accused the lead author of the paper, Thomas Karl, who was until last year director of the NOAA section that produces climate data – the National Centers for Environmental Information (NCEI) – of ‘insisting on decisions and scientific choices that maximised warming and minimised 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’.
