“There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.”
― Mark Twain
Like the US, Australia has a very hot past which is incompatible with climate crisis hysteria. This compels government scientists to find creative ways to make the past heat disappear.
In the US, the primary technique used to hide the hot past is to cool older temperatures, and warm more recent ones.
But in Australia, the primary technique is to hide older temperatures.

Australian government “scientists say” that observers in the past simply weren’t smart enough to know whether the thermometer they were reading was in the sun or in the shade.
The global standard for temperature measurement includes the use of a Stevenson screen, which is a white louvred box allowing ventilation and ensuring thermometers inside are never exposed to the sun.
A Stevenson screen was not installed in Bourke until August 1908, meaning temperature readings from before that could be inflated by as much as 2C.
Australia has been surrounded by unusually cold water for most of the last few months.

This led to the coldest summer day on record a few weeks ago, but it also led to drought and the recent heatwave and fires, which have been hyped by the Bureau of Meteorology as the worst ever.

Let’s look at some past heatwaves, and see if the BOM excuses for hiding past heat are valid. The January 1878 heatwave was global, and caused birds to drop out of the trees. BOM seems to believe that the birds would have been OK, had observers kept their thermometers out of the sun.

Minnesota had their warmest winter on record in 1878.

The 1896 heatwave in Australia was the hotetst on record, and killed huge numbers of kangaroos, dingoes, rabbits and birds. Once again, BOM seems to believe that these animals were victims of improperly situated thermometers.
Night time temperatures were extremely hot too. Apparently BOM believes these were due to thermometers in the sun at midnight.

Victoria’s hottest day on record was January 7, 1906. The Argus reported that the equipment was reliable, and that temperatures were taken every half hour both in the shade and the sun. Sun temperatures were typically 50-60 degrees hotter than shade temperatures.

But BOM argues that the observer reading the thermometer wasn’t clever enough to know if the thermometer was in the sun, and that it read two degrees too high.

BOM prefers thermometers like the one at Sydney, located adjacent to 22 lanes of asphalt, and reflecting afternoon sun off tall buildings on to the thermometer housing.
They also believe that all the dead animals in Victoria in 1906 were the victims of badly placed thermometers.

BOM claims that a change to the thermometer housing at Bourke in 1908 caused a step change of 2C cooling, but the temperature data shows nothing of the sort. Temperatures at Bouke cooled steadily from he 1870s to the 1970s.
And the same at other locations in southeast Australia
BOM claims that December 17 was the hottest day on record in Australia, but that claim is not defensible.

And not surprisingly, the person and money behind all of the fake claims about Australian fires is being controlled by Tim Flannery.

None of the claims being made about record heat or fires are credible, but that is standard operating procedure for climate scientists.
A Stevenson screen was not installed in Bourke until August 1908, meaning temperature readings from before that could be inflated by as much as 2C.
But apparently 12C of UHI is much less than 2C of sunlight. New math.
The term “heat island” describes built up areas that are hotter than nearby rural areas. The annual mean air temperature of a city with 1 million people or more can be 1.8–5.4°F (1–3°C) warmer than its surroundings. In the evening, the difference can be as high as 22°F (12°C).

It’s the Bureau of Magic, because they make data disappear.
Australian voters are who they want to fool. Tony is who they want to evade.
I am surprised that a Stevenson screen was not installed in Bourke until August 1908. That would be 50 years or more after they were installed in Sydney, Newcastle and country towns like Bathurst. So what sort of screen did they use? A Glaisher? When Stevensons were the standard.
Sir Charles Todd installed Stevenson screens across South Australia in the 1860’s and early 1870’s. In Adelaide he initiated a long running comparison (over 30 years) between a Stevenson and a Glaisher screen on the same site. The result was that the Glaisher gave an average of about 1℃ warmer.
In any case, the BoM has converted many stations in the last 20 odd years to digital thermometers (which give higher readings) AND a smaller “Stevenson” screen (which gives higher readings). So much for their accuracy.
Since 2000 the Green movement has really been hysterical here in Australia.
There’s been a couple of effects of this:
– Very strong opposition to any bushfire control clearing
– Increased numbers of tree-changers
Many of the houses burned in the bushfires here in the last month have been in country settings surrounded by bush. With lots of fire-loving eucalypts. Very nice places to live, except for the bushfire problem, which the tree-changer owners seem to have forgotten about when they built their houses.
In the decade 2000-2009 there were the 2003 Canberra fires, which melted the Mt Stromlo astronomy observatory, and the 2009 Black Saturday fires in Victoria. Many people were killed in those fires. Victoria and Canberra have two of the greenest government administrations in the country.
The 2009 fire is especially interesting in light of the following story:
‘Illegally’ clearing his property cost him $100k in fines. But when the Black Saturday fires killed 173, his family and home survived while his neighbours died – so LIAM SHEAHAN asks, why can’t we control our own homes? (Daily Mail, 14 Nov)
He was fined $50,000 by the town council for clearing bushland around his house, plus another $50k in court costs. And his family were the only ones to survive for about a mile in every direction.
That shows just how insane bushfire policy has become in the Green age.
A simple question. Do you accept that temperature on Earth is maintained and held in by the “greenhouse gases”? You might like to compare the temperature on Mercury(much closer to the sun) than that of Venus. Much further from the sun than mercury but with dense greenhouse gases.
Now ask yourself if you accept that greenhouse gases on Earth are rising? Then check the correlation between greenhouse gas rise and the modelling on associated temperature rise.
Really, of course we have had very hot weather previously. Many factors can give high temperatures and have done so in the past. What is different this time is the association with greenhouse gases. Previous greenhouse gas temperature raising was assiciated with impact events and these then gradually dispersed. We have no impact event this time, merely human responsibilty. If we continue to add gases what do you think will happen?
