– Deep in the burning forests south of Sydney last week, volunteer firefighters were clearing a track through the woods, hoping to hold back a nearby blaze, when one of them shouted over the crunching of bulldozers.

“Don’t take photos of any trees coming down,” he said. “The greenies will get a hold of it, and it’ll all be over.”

The idea that “greenies” or environmentalists would oppose measures to prevent fires from ravaging homes and lives is simply false. But the comment reflects a narrative that’s been promoted for months by conservative Australian media outlets, especially the influential newspapers and television stations owned by Rupert Murdoch.

And it’s far from the only Murdoch-fueled claim making the rounds. His standard-bearing national newspaper, the Australian, has also repeatedly argued that this year’s fires are no worse than those of the past — not true, scientists say, noting that 12 million acres have burned so far, with 2019 alone scorching more of New South Wales than the previous 15 years combined.

And on Wednesday, Murdoch’s News Corp., the largest media company in Australia, was found to be part of another wave of misinformation. An independent study found online bots and trolls exaggerating the role of arson in the fires, at the same time that an article in the Australian making similar assertions became the most popular offering on the newspaper’s website.

It’s all part of what critics see as a relentless effort led by the powerful media outlet to do what it has also done in the United States and Britain — shift blame to the left, protect conservative leaders and divert attention from climate change.

“It’s really reckless and extremely harmful,” said Joëlle Gergis, an award-winning climate scientist at the Australian National University. “It’s insidious because it grows. Once you plant those seeds of doubt, it stops an important conversation from taking place.”

News Corp. denied playing such a role. “Our coverage has recognized Australia is having a conversation about climate change and how to respond to it,” the company said in an e-mail. “The role of arsonists and policies that may have contributed to the spread of fire are, however, legitimate stories to report in the public interest.”

Yet, for many critics, the Murdoch approach suddenly looks dangerous. They are increasingly connecting News Corp. to the spread of misinformation and the government’s lackluster response to the fires. They argue that the company and the coalition led by Prime Minister Scott Morrison are responsible — together, as a team — for the failure to protect a country that scientists say is more vulnerable to climate change than any other developed nation.

In late December, the Oz, as the News Corp.-owned paper is known here, heavily promoted an interview with the government’s energy minister, Angus Taylor, warning that “top-down” pressure from the United Nations to address climate change would fail — followed by an opinion piece from Taylor on New Year’s Eve.

An editorial published by the paper on Thursday said, “On a dry continent prone to deadly bushfires for centuries, fuel reduction through controlled burning is vital.” It went on to add: “Changes to climate change policy, however, would have no immediate impact on bushfires” — a stance that fits hand in glove with government officials’ frequent dismissals of the “boogeyman of climate change.”

It’s that echoing between officialdom and Murdoch media that has many people so concerned.

“Leaders should be held to account and they should be held to account by the media,” said Penny Sackett, a physicist, astronomer and former chief scientist for Australia.

Of course, it is often hard to know just how much influence any media company has. But there are signs that the Murdoch message is making headway — at least in terms of what people make a priority. Many firefighters working the smoky hills south of Sydney hesitated to state their views on climate change this week (some said senior leaders had told them to avoid the issue). But they were quick to argue for more backburning.

Similarly, in Bairnsdale, Tina Moon, whose farm was devastated by the fires, said she was mostly furious about the government’s failure to clear the land around her property.

“I don’t think it’s climate change,” she said.
