The University of Melbourne's page on the Gergis paper has been updated:
An issue has been identified in the processing of the data used in the study, "Evidence of unusual late 20th century warming from an Australasian temperature reconstruction spanning the last millennium" by Joelle Gergis, Raphael Neukom, Stephen Phipps, Ailie Gallant and David Karoly, accepted for publication in the Journal of Climate.
The authors are currently reviewing the data and methods. The revised paper will be re-submitted to the Journal of Climate by the end of July and it will be sent out for peer review again.
I do think that this time around the Journal of Climate should ask the authors to archive the data series that didn't pass the screening as well as those that did.
