A climate change study that was debunked by realists shortly after it was published in 2018, was used in the The UN’s Intergovernmental Panel on Climate Change (IPCC) Special Report anyway.
It took ten months to be officially retracted even though the problems were spotted soon after publication.
What does it say about the group think resulting in junk science being used to fuel climate alarmism?
Why would the IPCC use a widely disputed study for their report and then not retract their claims about sea level rise?
Retraction Note: Quantification of ocean heat uptake from changes in atmospheric O2 and CO2 composition
Retraction to: Nature https://doi.org/10.1038/s41586-018-0651-8, published online 31 October 2018.
Shortly after publication, arising from comments from Nicholas Lewis, we realized that our reported uncertainties were underestimated owing to our treatment of certain systematic errors as random errors. In addition, we became aware of several smaller issues in our analysis of uncertainty. Although correcting these issues did not substantially change the central estimate of ocean warming, it led to a roughly fourfold increase in uncertainties, significantly weakening implications for an upward revision of ocean warming and climate sensitivity. Because of these weaker implications, the Nature editors asked for a Retraction, which we accept. Despite the revised uncertainties, our method remains valid and provides an estimate of ocean warming that is independent of the ocean data underpinning other approaches. The revised paper, with corrected uncertainties, will be submitted to another journal. The Retraction will contain a link to the new publication, if and when it is published.
New IPCC report on ocean warming cites a flawed and retracted paper
Anthony Watts / September 27, 2019
A major new report about the dramatic warming of the oceans cites a 2018 Nature paper on the topic that was retracted earlier this week — the same day, in fact, that the report dropped.
But one of the authors of that paper tells Retraction Watch that the Intergovernmental Panel on Climate Change (IPCC) Special Report, released September 25, must have meant to cite a different paper by the same authors.
The report concluded that: It is virtually certain that the global ocean has warmed unabated since 1970 and has taken up more than 90% of the excess heat in the climate system (high confidence). Since 1993, the rate of ocean warming has more than doubled (likely)
What makes the flawed citation more remarkable is that researchers have been aware of errors in the analysis for more than 10 months. As we — and others — have reported, almost immediately after publication of the paper Nic Lewis blogged about his concerns with the analysis, concerns that eventually prompted the retraction.
