The lost climate knowledge of Deacon 1952: hot dry summers from 1880-1910

Once upon a time, Australian climate scientists discussed and published climate trends of the late 1800s. And lo, the long lost hot weather decades were apparent in many places in inland South Eastern Australia. While skeptics are accused of cherry picking data from Bourke, Rutherglen and Deniliquin, there are plenty of other examples. In the last post, the 1953 Argus story described hotter drier summers in Omeo, Bendigo, Hay, Bourke, Alice Springs, Echuca, Albury, and Cooma. Here is a Deacon et al peer reviewed graph of the long term trends at Hay, Narrabri, Bourke and Alice Springs.

Thanks to Chris Gillham for finding the Deacon paper of 1952. [On another point, I’ll have a response up to the new BOM “adjustments” page later. In short, their data still has many inexplicable errors like where maxima are lower than minima, and they are still not providing all the details we need to replicate their data and homogenization methods. – Jo]

But just have a look at this graph. Degrees Fahrenheit of course. State of the art, 1952.

These  cooling trends cover “only” a couple of million square kilometers of Australia:

Imagine, they even had barometric data from 1880 in small country towns of NSW.

There is a lot more data from South East Australia than other parts of the nation.  But the CSIRO and BOM don’t seem to be in a hurry to try to calculate the longer trends in those places, where the data is available. There are legitimate reasons why it may be difficult to compare the older trends with the newer data. But it’s a public discussion we need to have. Shouldn’t the Australian public know about all this carefully recorded data, and the very hot summers that happened when CO2 was ideal?

  1. Cobber, this item is a piece of cod. The knowledge of people like Deacon, Cornish, even Sir RA Fisher, who is buried in Adelaide South Australia where he went to live after retiring from Rothamsted and worked with his mate Dr Cornish, is only forgotten. It is easily recovered. Even I managed to find it, and Cornishes interesting work, even Fisher at Rothamsted, and I was only interested in sunspots and rainfall. What seems to be lost is ability to read the stuff and JoNova is one of the unable as far as I can see. She certainly knows how to switch on her hangers-on. The comments section is a great hoot. Deacon was trying to understand his subject, to make sense of it, with only a book of log tables, a pencil and some data, whereas Jo has an axe to grind. I wonder if it a Kelly? I find it amazing they haven’t uncovered the very lost ET Quayle, who is far more interesting and radical, or Griffith Taylor who was sort of run out of the country (Australia) for a saying, among other things, the place had a limit on the population because of the physical resources available to it. he put the limit at 20 mill.
