James Murdoch, the son of News Corp Chairman Rupert Murdoch , and his wife, Kathryn, unleashed fierce criticism Tuesday over the handling of climate change and environmental issues by the media titans slate of conservative news outlets.

In a statement to The Daily Beast , a spokesperson for the couple said the Murdochs were disappointed with what they called ongoing denial at both Fox News and the broader News Corp empire, which owns much of the media outlets in Australia. The country is currently fighting a scourge of devastating bushfires that have left at least 28 people dead and scorched more than 15 million acres.

Kathryn and James views on climate are well established and their frustration with some of the News Corp and Fox coverage of the topic is also well known, the spokesperson told the Beast. They are particularly disappointed with the ongoing denial among the news outlets in Australia given obvious evidence to the contrary.

The statement is a rare public rebuke of Rupert Murdochs empire from one of his closest family members. News Corp has been accused in recent weeks of trying to downplay Australias deadly fire season within the Australian media while promoting misinformation about what has caused the disaster .
