Scientists have been forced to withdraw a study on projected sea level rise due to global warming after finding mistakes that undermined the findings.
The study, published in 2009 in Nature Geoscience, one of the top journals in its field, confirmed the conclusions of the 2007 report from the Intergovernmental Panel on Climate Change (IPCC). It used data over the last 22,000 years to predict that sea level would rise by between 7cm and 82cm by the end of the century.
At the time, Mark Siddall, from the Earth Sciences Department at the University of Bristol, said the study « strengthens the confidence with which one may interpret the IPCC results ». The IPCC said that sea level would probably rise by 18cm-59cm by 2100, though stressed this was based on incomplete information about ice sheet melting and that the true rise could be higher.
Announcing the formal retraction of the paper from the journal, Siddall said: « It’s one of those things that happens. People make mistakes and mistakes happen in science. » He said there were two separate technical mistakes in the paper, which were pointed out by other scientists after it was published. A formal retraction was required, rather than a correction, because the errors undermined the study’s conclusion.
