Scientists behind ocean warming study say errors were made

(CNN)Scientists behind a study that found the world's oceans were warming faster than previously believed have said their work contained errors, which means they cannot reach conclusions with such certainty.

The issues "do not invalidate the study's methodology or the new insights into ocean biogeochemistry on which it is based," said co-author Ralph Keeling, in a note added to the original news release on the study from the Scripps Institution of Oceanography. But they do mean the scientists must redo their calculations.

Study - Nature - November - Warming - End

The study, published in the journal Nature on November 1, found that "ocean warming is at the high end of previous estimates." The researchers, led by Laure Resplandy of Princeton University, used precise measurements of atmospheric oxygen and carbon dioxide between 1991 and 2016 to produce an independent estimate of ocean heat uptake over that period.

Since publication, two problems had come to their attention, Keeling said, one of them related to incorrectly treating systematic errors in the measurements of oxygen.

Effect - Corrections - Impact - Calculations - Heat

"We expect the combined effect of these two corrections to have a small impact on our calculations of overall heat uptake, but with larger margins of error," said Keeling. "We are redoing the calculations...
