He declared a United Nations report on climate change "got it wrong by almost 100 per cent", but shock jock Alan Jones was the one who blundered, Australia's media watchdog has found.

The Australian Communications and Media Authority on Friday found the 2GB host, described on the station's website as "a phenomenon" and "the nation's greatest orator and motivational speaker", breached commercial radio codes in 2013 by making inaccurate comments about the rate of global warming as reported by the Intergovernmental Panel on Climate Change.

The station argued that Jones relied on a front page article in The Australian – an article that was based on incorrect information published in Britain's Mail on Sunday, and which was corrected before Jones went to air.

During his morning program on September 24, 2013, Jones discussed the leaked findings of a fifth draft report prepared by the IPCC.
