A former scientist at the National Oceanic and Atmospheric Administration (NOAA) in Washington, D.C., made waves this past weekend when he alleged that climate scientist Thomas Karl, the former head of a major NOAA technical center, “failed to disclose critical information” to the agency, journal editors, and Congress about the data used in a controversial study published in Science in June 2015. Karl was the lead author of that paper, which concluded that global surface temperatures continued rising in recent years, contrary to earlier suggestions that there had been a “pause” in global warming.
John Bates, who retired from NOAA this past November, made the claims in a post on the prominent blog of Judith Curry, a climate researcher who recently retired from the Georgia Institute of Technology in Atlanta and has walked the line between science and climate contrarians over the past decade. Bates’s complaints were also the centerpiece of a story published Sunday by David Rose of the United Kingdom’s The Mail on Sunday, a tabloid, which claimed that national leaders “were strongly influenced” by the “flawed NOAA study” as they finalized the 2015 Paris climate agreement.
Rose's story ricocheted around right-wing media outlets, and was publicized by the Republican-led House of Representatives science committee, which has spent months investigating earlier complaints about the Karl study that is says were raised by an NOAA whistleblower. But ScienceInsider found no evidence of misconduct or violation of agency research policies after extensive interviews with Bates, Karl, and other former NOAA and independent scientists, as well as consideration of documents that Bates also provided to Rose and the Mail.
