Climate experts wrong on Australian frosts, and media say nothing

The IPCC experts were sure would be less frosts in Australia, but buried in a government funded ABC weather report was the virtually unknown admission that the frost season is actually growing across southern Australia, not shrinking. And in some places by an astonishing 40 extra days a year. What's more, the researchers have known about this long term trend for years but didn't think to mention it, and the ABC didn't have a problem with that either. (It's not like farmers need to know these things?)

When asked for an explanation for the increase in frosts, the ANU climate expert said "I think this is one of those climate surprises," as if the IPCC unexpectedly won a game of Bingo, instead of getting a core weather trend 100% wrong.

We note the ABC feigned journalism to cover up for the Bureau of Meteorology and IPCC failures. Where were the headlines: "Climate Change causes more frosts, not less", or "IPCC models dangerously misleading on frosts?" Did any Australian farmers and investors buy up properties and plant the wrong crops based on the global warming misinformation repeated or tacitly endorsed by the ABC, BoM and CSIRO?

Frost damage costs Australian farmers around $400 million each year. (Perhaps if we sold the ABC we could cover that).
Frost expected across nearly every state and territory in Australia this weekend

By Tyne Logan, ABC Australia

Buried under 450 words of weather, trite caveats, and preamble the ABC journalist finally gets to a new virtually unknown climate trend that affects farmers, investors, researchers, and rural Australia:

The latest Intergovernmental Panel on Climate Change report projected, with high confidence, that frost events would decrease, in general, across southern Australia in the future with climate change.

ANU climate applications scientist Steven Crimp said some parts of New South Wales were now experiencing five more frost events on average each year, compared to 1960.
And he has known for years:
He said this was based on local weather station data between 1960 and 2018, but the trend was unlikely to have changed much in the past five years.

"I think this is one of those climate surprises," he said.
Scientifically they are not caught unaware because climate models are useless politicized fantasies, it's because there is more "climate-nuance" around now:
"Despite the sort of overall warming trend in our temperatures, the extremes of our temperatures, be they hot or cold, are acting in a slightly more nuanced and complex way, which can be quite surprising at times," he said.

BOM forecast overnight minimum temperatures to fall well below zero across large swathes of the country May 21, 2023.
But jokes aside, this actually seems like a trend that matters:
Dr Crimp said they had also found the frost season was lengthening across southern Australia.

"So if we think about the east coast first, we see an earlier start and a later finish to that frost window," he said. "In some cases, the extension of that frost window is greater than 40 days.

"But in Western Australia in particular, we see that it's less to do with the later frost occurrence, but more earlier frost occurrence."
The frosts are due to the dry conditions, says Dr Crimp, putting in an admirable effort at scientific-word-salad to cover up for what he's not allowed to say — that they have no idea.
Why aren't frost days decreasing?

Dr Crimp said, ironically, the observations could be explained by the types of weather system that brought warmer, drier weather. That was high pressure systems which often produced the clear, still nights needed for frost to settle.

"As anyone knows who's outside at night in winter, you have to have those clear night skies and the atmosphere needs to be very dry," he said.

"That way the surface of the Earth loses heat very rapidly and any moisture in the air then condenses as a frost. "So because we are getting those dry conditions that are starting to emerge, that is more conducive for frosts to occur."
But the truth is that, on average, and a priori — global warming would increase humidity and global cooling would dry the air out. And carbon dioxide is supposed to work at night time too — increasing minimum temperatures. All these factors make frosts less likely.

And yet the frosts happen.
Global warming 'science' has lost,
Being useless, at a terrible cost,
As their heat without end,
Is bucked by the trend,
Of Australia's more nights of frost.
