Plummeting Temperatures In Australia

Australia used to be very hot, which is why BOM hides all temperatures before 1910

The hottest year in Australia was 1900. This is where GHCN stations were located than year.

    Well there has been big warming since the 60s so that clearly means global warming! Who cares about the decades before then and that temperatures aren’t even back to that level. Just cherry pick and use the low period as the starting point/reference so the statement is technically correct.

    That’s what bugs me the most about these cultists as they seek to ignore the first half of the 20th century…well, at least when they aren’t trying to alter the data to be lower than it was.

    But Tony/Steve – Australia is about the same size as the United States which is only a small percentage area-wise of the planet. Your myopia is showing!

    What happened in the late 70s?

  4. TedL says:

    Jennifer Marohasy suggests that the Australia temperature record for the last 20 years is “not fit to purpose” due to misuse of data from automatic weather stations. Here is a link to her blog, in which the recent posts discuss this issue.
    In a nutshell, she points to evidence that the low temperature readings in automatic weather stations were limited by software, and the hottest one-second readings were recorded as the daily high temperatures, rather than the one-minute average. The combination biases temperatures to the warm side.

    Looking at your charts, it is interesting that after 1997 the trend is warmer.

    Reposting piece from yesterday demonstrating these soaring, ocean-boiling, thermometer-busting, time-to-panic temperatures down unduh:

  6. TedL says:

    This time period also corresponds more or less to the “Pause” in warming of global temperature. I don’t know how much Australian records contribute to the calculation of global temperatures, but if Australian temperature record is warmer than actual, then perhaps the Pause was cooler than reported.

    Here is UAH Australia for last 20 years.

    I would trust this FAR more than anything from BOM.

  8. The ol' Sea dog says:

    Do you have any more maps of areas where there is little or no recording of temperatures ?

  9. Rosco says:

    Australia is still pretty damn hot especially in December/January/February when it doesn’t rain.

    Winters aren’t as cold but as most of the temperatures are measured in larger urban areas that is possibly an artifact.

    Almost half of Australia is tropical after all – you wouldn’t expect the sale of thermal underwear to be prominent.

  10. Andy DC says:

    It appears that the 1940-1980 cooling may have been global rather than just northern hemispheric.

  11. John of Cloverdale, WA, Australia says:

    Interestingly, the BoM conveniently claim that the hot period temperature records (Federation Drought) of pre-1900 within Australia were unreliable, because these warm temperatures were recorded in an older style open thermometer stand (often a Glaisher stand in Australia). However this was not always the case, as Warwick Hughes and Jo Nova point out.

    Here is another informative link from Jo (The Mysterious BOM Disinterest in Hot Historic Australian Stevenson Screen Temperatures) which also shows a summary map on when Stephenson screens were installed in Australia.

    Then there was the deadly heatwave of 1896.

    Is the BoM ignoring these high temperature records deliberately?

    • Colorado Wellington says:

      BoM ignores it because Australia didn’t have standardized thermometers back in 1896 so the thousands fleeing to the Blue Mountains or the hundreds who died in the streets did not really know why. The suffering of the Australians was very subjective with maybe a little bit of panic and mass hysteria driven by the print media. You can see the same thing today when sensitive and impressionable Floridians watch a really bad climate change prediction on TV. Whole extended families suddenly break out in sweat and feel they must go looting in the strip mall.

      Its completely unreliable from a scientific point of view.

    I was unable to find a place where I could share this in better context, but I thought you’d get a kick out of this… It is the result of a couple of factoids I gathered several years ago. Termites exhale CO2 at the rate of 50mL/hour/gram of body mass. Their metabolism remains very consistent, regardless of age and activity level.
    Some estimates place the total biomass of termites to be as high as ten times that of humans. I’ll assume 1:1, with an average mass of 45 Kg per person.

    50 mL/Hr/Gram * 24 hours * 365.25 days = 438,300 mL/Year/Gram
    438,300 mL/Year/Gram * 0.001977 g/mL = 866.5191 Grams/Year/Gram (or Kg/Yr/Kg)
    45 Kg * 7.35 Billion people = 330,750,000,000 Kg Termite Biomass
    330,750,000,000 Kg * 866.5191 Kg/Year/Kg = 286,601,192,325,000 Kg/Year CO2 exhaled

    I’ll be kind to the AGW crowd and calculate human respiration and add it to the total emissions:
    0.5 L/Breath * 20 Breaths/Min * 2% conversion = 0.2 L/Minute
    0.2 L/Minute * 60 Minutes * 24 Hours * 365.25 Days = 105,192 L/Year
    105,192 L/Year * 1.977 g/Liter = 207964.584 g/Year = 207.964584 Kg/Year
    7,350,000,000 people * 207.964584 Kg/person/Year = 1,528,539,692,400 Kg/Year

    The US EPA reports that humans produced 6,587 MMT (Million Metric Tons) CO2 in 2015, not including a -666.2 MMT CO2 sink from land use (reforestation/landscaping, etc)

    1,528,539,692,400 + 6,587,000,000,000 = 8,115,539,692,400 Kg
    (we’re not including the -666,200,000,000 Kg sink just for “goodwill”)

    If humans produced 8,115,539,692,400 Kg, and termites exhaled 286,601,192,325,000 Kg, humans only emitted 2.83% as much CO2 as termites did in 2015.

    Now lets consider all other insects (ants, flies and cockroaches are pretty numerous… and spiders…eek)
    and birds (estimated in the trillions)
    and reptiles and amphibians
    and fish (who occupy 2/3 the surface of the earth)
    and other mammals
    and bacteria.
