Celebrities and posturing greenies the world over have seized the opportunity of Australia’s bushfire catastrophe to push the dangerous myth that climate change is to blame.

“When one country faces a climate disaster, we all face a climate disaster,” Cate Blanchett declared at the Golden Globes on Sunday.

“Make no mistake. The tragedy unfolding in Australia is climate change-based,” said Russell Crowe.

“Australia is on fire,” tweeted teenage climate evangelist Greta Thunberg, decrying the lack of “political action [to combat] the climate crisis.”

“Australia is committing climate suicide,” ran the headline in the New York Times.

I’m sorry, but I lived in Australia through the past two decades of escalating fire crises and it’s not climate change that has caused today’s disaster, but the criminal negligence of governments that have tried to buy green votes by locking up vast tracts of land as national parks, yet failed to spend the money needed to control ground fuel and maintain fire trails.

Instead, they bowed to an ideology that obstructs necessary hazard reduction and prevents landowners from clearing vegetation around their own properties, all in thrall to the god of “biodiversity.”

How’s that biodiversity now on incinerated land sterilized of all life forms?

I’ve interviewed local volunteer firefighters who bitterly recounted the bureaucratic obstruction they faced in performing prescribed burns in the offseason to prevent uncontrollable summer conflagrations.

One of my guides was Australia’s foremost bushfire researcher, Dr. Phil Cheney, who has spent 30 years trying to convince authorities that if ground fuel is reduced in a scientific, systematic fashion every year, fire intensity is reduced to a manageable level, no matter what the weather conditions. A quadrupling of ground fuel means a 13-fold increase in the heat generated by a fire. Hazard reduction won’t prevent fire but it will reduce its intensity so that it can be controlled.

So whether or not you believe the most dire predictions of climate alarmists makes no difference. We can’t dial down the Earth’s temperature any more than we can lock up every teenage arsonist.

The only practical way to prevent unmanageable fires is to reduce the one variable we control: ground fuel.

“Climate change has not caused the current fire crisis,” says Australian Capital Territory forester and former acting fire control officer Ian McArthur.

“Long unburnt fuels in national parks are the primary cause. Basic fire management states that a fire needs oxygen, a heat source and fuel. The only one of those that can be manipulated is fuel. The more fuel, the more intense the fire, the harder it becomes to suppress the fire.”

As dangerous fuel loads have been allowed to build up in southeast Australia, ever more cataclysmic fires have erupted until, finally, this season came a perfect storm of the country’s most extreme drought since the turn of the 20th century and record high temperatures.

At least 26 people have been killed as bushfires burned more than 12 million acres — an area more than one-third the size of New York state.

It is an ecological disaster. The fires are estimated to have spewed into the atmosphere the equivalent of two-thirds of Australia’s entire annual carbon emissions.

But it could have been avoided if the warnings had been heeded.

For more than 20 years, Australia’s Greens party and greenies infiltrating government bureaucracies have obstructed the hazard reduction that experts like Cheney and McArthur recommend.

Despite their attempts to rewrite history, submissions to bushfire inquiries from as far back as 1992 are evidence of green opposition to hazard-reduction burning as a threat to “biodiversity,” and their urging that resources be spent instead on water-bombing helicopters, as well as on the amorphous task of stopping climate change.

Anecdotes illustrate the problem.

Last September, protesters in East Gipps­land in the state of Victoria stopped a hazard-reduction burn that they said was “killing baby birds alive.”

“I’m more worried about climate change,” one protesting grandmother told the Australian Broadcasting Corporation. As a result, the hazard reduction was reduced to 3 percent of the area planned. Two months later, East Gippsland was burned out.

Punishment for unauthorized hazard reduction has been brutal. For instance, when electricity authority TransGrid in 2001 cleared a 200-foot-wide firebreak to protect high-voltage lines that ran through rugged bushland near the national capital of Canberra, the authority was sued by four government agencies and fined $1 million. A year later, when a calamitous fire swept the Snowy Mountains in New South Wales, TransGrid’s firebreak was the only safe haven for kangaroos, wallabies and three forest workers.

In the dairy town of Taree, farmer Warren Buttsworth was charged with “unlawful clearing of native vegetation” because he dug out the roots of casuarina trees still smoldering underground weeks after a bushfire was extinguished.

In rural Victoria, volunteer firefighter Liam Sheahan was almost bankrupted when he was fined $50,000 for clearing trees to create a firebreak around his property. Five years later, when the deadly 2009 Black Saturday fires swept through the area, his was the only house left standing.

Last year, under pressure from green activists, the government of New South Wales, home to much of the fire destruction today, even listed prescribed burning as a “key threatening process” under the Environmental Protection and Biodiversity Conservation Act.

Climate change has become an excuse for green mismanagement.

Fake-news dragon $lain

Bravo to Nick Sandmann, the Covington, Ky., Catholic high school student who scored a victory this week over fake news. In a case of David defeating Goliath, CNN has settled Sandmann’s $275 million lawsuit for an undisclosed amount.

That’s a legal remedy, but where is the contrition from news organizations that smeared a 16-year-old as a racist and threatened his safety? Remember former CNN host Reza Aslan’s tweet: “Have you ever seen a more punchable face than this kid’s?”?

It was the Covington boys who were victims of racism when they were accosted by members of the anti-white, anti-Semitic Black Hebrew Israelite movement while waiting for a bus home from an anti-abortion march in Washington last year. Instead, they were falsely accused of racism toward a Native American activist.

Sandmann’s real crime was to be Catholic and anti-abortion and wear a MAGA cap. That’s why news outlets maliciously leaped to judgment without basic due diligence.

Shameless Pelosi is tweet-le dumb

Nancy Pelosi should be ashamed of her tweet swatting the president at a time of national peril. As Iran’s missiles threatened American lives, the Democratic House speaker accused Donald Trump of “needless provocations.” This followed her incendiary letter to colleagues Sunday suggesting the president had broken international law.

Her fecklessness extended to refusing to take a call from Vice President Mike Pence informing her of the Iranian attack on the US bases in Iraq Tuesday night, just before she headed off to a restaurant launch in Washington, where she was photographed holding court 15 minutes before tweeting: “Closely monitoring the situation following bombings targeting US troops in Iraq.”
