An widely-circulated study which concluded that global warming is far worse than previously thought has been called into question by a math error
Princeton scientist Laure Resplandy and researchers at the Scripps Institution of Oceanography concluded in October that the Earth’s oceans have retained 60% more heat than previously thought over the last 25 years, suggesting global warming was much worse than previously believed.
The report was covered or referenced by MSM outlets worldwide, including the Washington Post, New York Times, BBC, Reuters and others.
The Washington Post, for example, reported: “The higher-than-expected amount of heat in the oceans means more heat is being retained within Earth’s climate system each year, rather than escaping into space. In essence, more heat in the oceans signals that global warming is more advanced than scientists thought.”
The New York Times at least hedged their reporting, claiming that the estimates, “if proven accurate, could be another indication that the global warming of the past few decades has exceeded conservative estimates and has been more closely in line with scientists’ worst-case scenarios.”
Unfortunately for the Princeton-Scripps team, it appears that their report has been proven inaccurate.
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. –Daily Caller
“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,” wrote Lewis in a blog post published on climate scientist Judith Curry’s Climate Etc. website.
After correcting the math error, Lewis found that the paper’s rate of oceanic warming “is about average compared with the other estimates they showed, and below the average for 1993–2016.”
Lewis’s conclusion was replicated and supported by University of Colorado professor, Roger Pike, Jr., who tweeted his work. …
