More on the "whistle blower" The whistleblower Bates recently retired from NOAA after a career working primarily on satellite measurements used for weather forecasting. Recently, he was also in charge of data-archiving efforts for satellite and surface temperature records. Bates alleges that NOAA's Tom Karl and the rest of the team behind the paper failed to adequately follow NOAA’s internal processes for archiving their data and stress-testing the updated databases they used. Bates also questions the way in which some sea surface temperature measurements were adjusted to sync them up with the rest of the measurements, falsely claiming that the technique alters the warming trend. In a blog post, Maynooth University research Peter Thorne—who worked on both the land and sea databases underlying the Karl paper but not the Karl paper itself—disputed many of Bates’ claims. First off, Thorne notes that Bates was not personally involved in the research at any stage. And while Bates claims that Karl made a series of choices to exaggerate the apparent warming trend, Thorne points out that this would be difficult for Karl to do since he didn’t contribute to the underlying databases. Karl’s paper simply ran those updated databases through the same algorithm NOAA was already using. Ars talked with Thomas Peterson, a co-author on the Karl paper who has since retired. Peterson provided some useful context for understanding Bates’ allegations. The satellites that Bates worked with were expensive hardware that couldn't be fixed if anything went wrong after they were launched. The engineering of the software running those satellites sensibly involved testing and re-testing and re-testing again to ensure no surprises would pop up once it was too late. Bates expected the same approach from his surface temperature counterparts, but Peterson explained that their work with weather station data was not nearly so high-stakes—problems could easily be fixed on the fly. The engineering-style process NOAA was using for endlessly double-checking the software for all dataset updates could drag on for quite a long time—years, in fact—and Bates opposed any attempt to speed this up. Peterson and other scientists were naturally anxious to incorporate changes they knew were scientifically important. Bates alleges that the Karl paper was “rushed” for political reasons, but Peterson said the reality was that NOAA was well behind the times, waiting to include known improvements like additional recording stations in the rapidly warming Arctic. “I had been arguing for years that we were putting out data that did not reflect our understanding of how the temperature was actually warming—[for] literally years we slowed down to try to account for some of these processing things that we had to do,” Peterson said. (At the time of the Karl paper, NOAA’s dataset showed less warming in recent years than other datasets, like NASA’s.) Bates also claims that there were bugs in the land station database software that were ignored in the Karl paper. But according to Peterson, the slight day-to-day variability seen in the software’s output was simply the result of the fact that new data was added every day. Stations that straddled statistical cut-offs might fall on one side of the dividing line today, and on the other side tomorrow. There was nothing wrong with the software, they realized. It was just silly to re-run it every single day. There may also be something beyond simple “engineers vs. scientists” tension behind Bates’ decision to go public with his allegations. Two former NOAA staffers confirmed to Ars that Tom Karl essentially demoted John Bates in 2012, when Karl was Director of NOAA’s National Centers for Environmental Information. Bates had held the title of Supervisory Meteorologist and Chief of the Remote Sensing Applications Division, but Karl removed him from that position partly due to a failure to maintain professionalism with colleagues, assigning him to a position in which he would no longer supervise other staff. It was apparently no secret that the demotion did not sit well with Bates. arstechnica.com
