“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.
I hadn’t realized previously that Australia is the land of the midnight sun. Thanks for clearing that up BOM.
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.
Like in 1878, the January 1906 heatwave was global – with a very mild winter in Minnesota.
San Francisco was destroyed by earthquake and fire a few weeks later.
1934 brought a global heatwave and drought.
1934 was the hottest year on record in the US, which forced massive data tampering by US government scientists.
Australia’s had another massive heatwave in 1939, which was much hotter than this year.
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.
