few weeks ago, on an obscure climate-change blog, a retired government scientist named John Bates blasted his former boss on an esoteric point having to do with archiving temperature data. It was little more than lingering workplace bad blood, said Dr. Bates’s former co-workers at the National Oceanic and Atmospheric Administration. Dr. Bates had felt he deserved his boss’s job at NOAA, they said, not the demotion he received. “He’s retaliating. It’s like grade school,” said Glenn Rutledge, a former physical scientist at NOAA who worked with Dr. Bates. But in what seems like a remarkable example of office politics gone horribly wrong, within days the accusations were amplified and sensationalized — in the pages of the British tabloid The Mail on Sunday — inciting a global furor among climate-change deniers. The Mail claimed that Dr. Bates had revealed fraud in important research by NOAA that supports the widely held belief that climate change is real. “How world leaders were duped into investing billions over manipulated global warming data,” the article’s headline said. The scientific community swiftly shot down the accusations, and affirmed the accuracy of the research. And Dr. Bates himself later stated in an interview with a business news site that he had not meant to suggest that his former boss had played fast and loose with temperature data. “The issue here is not an issue of tampering with data,” Dr. Bates said.
