Hiding Australia’s Hot Past

CSIRO and BOM have known for at least 70 years that Australia was much hotter prior to 1910, so they erased all of the inconvenient data.

“Australian climatic data show that, for the period 1911-1950, the summer rainfall over much of the southern part of the continent was considerably greater than in the previous 30 years and, for the same season, mean daily maximum temperatures in the interior were appreciably lower.”


Bourke has had 841 days over 110F since 1872, half of which occurred before 1915.

“In February, 1892, Balranald recorded 125deg. ; in January, 1896, Brewarrina 123: December, 1879, Coonabarabran 125.6 ; Deniliquin 121.1 in January, 1878 ; and Euston 124.8 in December, 1897”

The Australian Bureau of Meteorology made all of these temperature records disappear by hiding temperature data before 1910.

    Australia, especially the southeast, is usually hotter during a centennial solar minimum because of increased El Nino conditions. The AMO was also warmer during the late 1800’s centennial solar minimum, directly due to an increase in negative North Atlantic Oscillation conditions (which are directly associated with slower trade winds), and also from an 8 month lagged positive feedback from El Nino episodes driving major AMO warm pulses.
    Solar cycles 14 and 15 in the early 1900’s despite having lower sunspot numbers, were not a continuation of the centennial minimum. The solar wind strength must have increased, with the same pattern as in the 1970-80’s, strongest around sunspot cycle minimum, driving colder AMO anomalies but heatwaves in the mid latitude continents, and weaker around sunspot maximum, driving warmer AMO anomalies and cold waves in the mid latitudes.

    Solar plasma temperature (same as speed) and pressure, note the higher values in the mid 1970’s and mid 1980’s:

    The real reason for starting in 1910 is the fact that official records started back then, of course.

    Also: “Research published in June by the Climate History Australia team presented the longest daily temperature record for Australia back to 1838. It revealed the southern Australian climate once experienced snow regularly and that heatwaves are now occurring more often.”

    Governments hide and then lie about everything. Whose going to tell him?😂

    As one born and raised in Moree, I can remember my mother slowly frying an egg on the metal-topped kitchen table. (And having a wood-fired stove helped a bit too!) Judging by the weather reports over the past few years – cooler – I doubt that would be something to do presently!

    Many thanks for exposing the BoM’s shenanigans, Tony. The sad thing is that few Australians will see it, and due to forty years of brainwashing, even fewer would believe it if they did.

  6. David G says:

    Ivan above is correct. Sadly, imminent climate change catastrophe is an idea very widely accepted in Australia, and alternative thought is mocked with the “denier” response.
    As our cheap and plentiful sources of power are closed down we face rolling blackouts quite soon I think (next few years). Meanwhile, politicians bleat on about future cheap and plentiful “renewable energy”, a misnomer if ever there was one.
    We will have to suffer I’m afraid, before the “peasants” revolt; and they will, eventually.
