The Press Council has handed down an adverse ruling against The Australian for a front-page article published in September last year that relied on a rapidly debunked Daily Mail story claiming the Intergovernmental Panel on Climate Change had revised down the rate of global warming since 1951.

In highly unusual language for the Press Council, it says it is a matter of "considerable concern" that The Australian delayed in acknowledging its errors. Asked to explain the strong language, Press Council executive director John Pender told Crikey "the initial error was very serious and prominent, was repeated unequivocally in a later editorial, and was not corrected with sufficient speed, clarity and prominence".
