Scientists Acknowledge Key Errors in Study of How Fast the Oceans Are Warming

A major study claimed the oceans were warming much faster than previously thought. But researchers now say they can't necessarily make that claim. From a report: Two weeks after the high-profile study was published in the journal Nature, its authors have submitted corrections to the publication. The Scripps Institution of Oceanography, home to several of the researchers involved, also noted the problems in the scientists' work and corrected a news release on its website, which previously had asserted that the study detailed how the Earth's oceans "have absorbed 60 percent more heat than previously thought." "Unfortunately, we made mistakes here," said Ralph Keeling, a climate scientist at Scripps, who was a co-author of the study. "I think the main lesson is that you work as fast as you can to fix mistakes when you find them." The central problem, according to Keeling, came in how the researchers dealt with the uncertainty in their measurements. As a result, the findings suffer from too much doubt to definitively support the paper's conclusion about how much heat the oceans have absorbed over time. The central conclusion of the study -- that oceans are retaining ever more energy as more heat is being trapped within Earth's climate system each year -- is in line with other studies that have drawn similar conclusions. And it hasn't changed much despite the errors. But Keeling said the authors' miscalculations mean there is a much larger margin of error in the findings, which means researchers can weigh in with less certainty than they thought.
