Error in Global Warming Study

Source: Daily Caller, Nov 2018

he recent headline-grabbing study that claimed global warming was heating the oceans up faster than expected suffers from a major math error, according to two researchers.

The study, which was published in a prestigious scientific journal at the end of October, put forward results suggesting global warming was much worse than previously believed. The media ate the results up.

Independent scientist Nic Lewis found the study had “apparently serious (but surely inadvertent) errors in the underlying calculations.” Lewis’ findings were quickly corroborated by another researcher.

Lewis found the new paper’s findings stemmed from a math error. Lewis said “a quick review of the first page of the paper was sufficient to raise doubts as to the accuracy of its results.”

“Just a few hours of analysis and calculations, based only on published information, was sufficient to uncover apparently serious (but surely inadvertent) errors in the underlying calculations,” Lewis wrote in a blog post published on climate scientist Judith Curry’s website.

Lewis found the study’s authors, led by Princeton University scientist Laure Resplandy, erred in calculating the linear trend of estimated ocean warming between 1991 and 2016. (RED line)

After correcting for the error, however, Lewis found the paper’s ocean warming rate “is about average compared with the other estimates they showed, and below the average for 1993–2016.” (BLUE Line)

Lewis’ results were replicated by University of Colorado professor Roger Pielke, Jr., who shared his analysis via Twitter on Tuesday.
