Spectacular Data Tampering At Deniliquin, NSW

Deniliquin is a small town located 270 km north of Melbourne and 370 km west of Canberra. It is one of the oldest stations in Australia and operated through 2003. The station showed a general cooling trend since the 1890s

Gavin made the cooling disappear a few years ago, and turned cooling into warming.


In order to hide the hot past, he knocked almost 2.5 degrees off of older temperatures.

This turned a sharp cooling trend into a strong warming trend.

Satellite photography shows that Deniliquin is fairly rural, but the station is in the middle of a neighborhood and was undoubtedly affected by the paving of the roads and growth of the town.

    The more these AGW promoters talk, the more obvious it is becoming that battle lines are being drawn between

    1. Joseph Stalin’s little helpers that adjust data to fit the UN’s Agenda 21 of worldwide totalitarian communism

    2. Truth of the benevolent reality that makes, sustains and destroys every atom, life and world.

    Camp #1 has all political power.

    Camp #2 cannot be defeated.

    Reblogged this on Climatism and commented:
    My historical and existing family grew up around Deniliquin. To have their temperature record trashed by global warming zealots abroad, in order to push their religious ideology/scam, is an unmitigated disgrace and yet another wicked blow to science and discovery.

    Shame on you Gavin Schmidt, NASA, NOAA, USHCN et al.


  3. Marsh says:

    They can tamper with the Data but the situation on the ground challenges it . The Winters here in Australia, particularly in the southern areas of NSW have become colder & they last much longer.
    Towns like Deniliquin that would rarely have seen Snow two decades ago,,, now commonly see it these days, even into the Spring season; not just the ranges but down into the river country. It is a fact that there’s been more Snow in Australia in recent years; yet NASA & IPCC avoid this reality!!

    Gee, there sure are a boatload of cherries on this tree! Should be one Hell of a harvest!

  5. Many of us have used the analogy of the emperor’s new clothes. But to my mind it’s got beyond some idiot thinking he’s walking down the street with clothes on.

    Now, they know they’ve got nothing to hide their embarrassment … nothing at all except the shear brass balls to carry on and dare the idiot politicians who also know this whole thing is crap to be the first to say they too don’t think there’s any clothes.

        Hey Gail! This is what I have on the back of my truck.


        I love watching hybrid drivers behind me trying to figure it out, you can usually watch their lips move under a furrowed brow. Then there is this idiot who hasn’t a clue…

        I was pretty confused looking at it. The person who had purchased the vehicle was obviously the victim of a very elaborate scam, but the logistics of successfully pulling off such an obtuse hoodwinking were puzzling me. How would someone successfully convince some poor rube that they were buying an “Eco-vehicle” that runs on hydrocarbons?

        Did the salesman tell the poor sap that the car could be filled up at any old regular gas station, and that the futuristic engine under the hood would, through the “power of osmosis” or some such tripe, extract the hydrocarbons from the gasoline? I could just imagine the car dealer pitching the sale to the unsuspecting lepton, “It’s fortified with science!”

        • rah says:

          “I was pretty confused looking at it.” Confusion is the normal state for such people.

          I imagine they would have a real conniption if they visited the two yards where we park our trucks when it gets really cold. Imagine what they would think of over 200 big trucks idling with no one in them!

          My truck, being new, has a thing called “idle management”. When it’s running I just push a button and it shuts down. The oil temperature is monitored and when it drops below 60 deg. F the truck kicks on and idles until it brings to temp up to normal operating level and the batteries are fully charged. Then is shuts down again. But most of the trucks have to just idle continuously to keep the diesel from gelling.

  6. A C Osborn says:

    Steven, have you conducted a study to test if for the USA in USHCN, GHCN and GISS they all use the same RAW data to start with?
    Or do they use different starting points as well as different processing?

  7. Mikky says:

    Sorry fellow sceptics, but after studying this (and surrounding) data for several weeks I can confirm that Deniliquin RAW Tmax is indeed a few degrees C too hot before 1908, possibly poor radiation screening in whatever they were using before a Stevenson screen was put in, which monthly data suggests was in late February 1908.

  8. Pete says:

    Mikky, would you please post the data for your conclusion.

  9. Peter says:

    Mikky you could do a pair wise analysis (by day of year or week) split on the date the equipment was changed. Such an analysis might show if there was a statistically significant step up in temperature at that point in time. I presume that adjustment factors used are derived in a similar fashion, not by human judgement?

  10. Marsh says:

    Businesses flooded as water pipes freeze:
    A Cressy St, Deniliquin business had 1000 litres of water drop into it on Sunday, after below freezing temperatures caused water pipes to break.

    TYLA HARRINGTON August 5, 2014 3:30am
    At least four Deniliquin businesses were flooded at the weekend after below freezing temperatures caused water pipes to break.

    Works manager with Deni Works Jim Grant said the -2.1°C on Saturday and -3.5°C on Sunday — the coldest August temperature on record in Deniliquin — caused the water to freeze and led to several water pipes expanding and cracking.

    Mr Grant said he was aware of four businesses which had flooded, while at least five homes lost water supply because their water had frozen. – end quote –

    We should remember : Deniliquin is one of the hottest towns in the southern region of NSW.
    When the Graphs & Predictions don’t match the outcomes ; the evidence reveals corruption.
    The Coldest August temperature on record – “was last year” ; that is not a Warming trend…

  11. Mikky says:

    Here is convincing (to me) evidence for Deniliquin being recorded too hot prior to 1908. It is not credible for Deniliquin to be 1C warmer than Adelaide after 1908, but not before:

    • AndyG55 says:

      Many places in central Australia recorded very high temperatures around 1890-1910

      Adelaide would always be moderated by its ocean proximity.

      You need to try to find places that are more in the interior of Australia to make a valid comparison.

      • AndyG55 says:

        If you have access to data, look at places like Echuca, Wagga Wagga, Hay, Broken Hill, West Wyalong, Griffith, Ivanhoe, Swan Hill, Wangaratta, Shepparton, Albury, Mildura.

        At least a few of these places should have pre 1910 data.

      • AndyG55 says:

        For consideration.

    • There is no step down there. You are seeing things you want to see.

      • Gail Combs says:

        He is ‘seeing’ the natural variation that the BEST AlGoreRhythm ‘sees’ and then uses as an excuse for modifying the data.

        Notice in both cases there are no written record by the observer/data recorder to back up the guess work.

        However we do have this: Instructions for Voluntary Observers, Washington DC Government Printing Office On page 22 are the instructions for the construction of a Stevenson Screen.

        Another book The American Meteorological Journal, Volume 8 from 1891 also mentions the ‘regulation Stevenson screen’

        An Account of the “Leste,” or hot wind of Madeira
        by H. Coupland Taylor, M. D. F. R. Met. Soc.

        Being an invalid, I must beg for the indulgence of the Society for the irregular times of obervation and the other defects the Fellows may discover in the following paper.

        I must first state that my insturments are placed in a regulation Stevenson screen…. The maximum and minimum thermometers are by Casella, and duly tested at Kew….I also have had in use for some months a self-registering hair hygrometer by MM. Richard Freres of Paris, and likewise a thermograph by the same makers but no very severe Leste has occurred since I had them.

        This “Leste” is a very dry and parching wind and sometimes very hot,….

        The “Leste” occurs in Spain.

        And finally we have this from Jo Nova.

        Excuses Excuses! Neville Nicholls and the Stevenson screens that didn’t exist, or did and were “cracked”?

        Neville Nicholls and Sophie Lewis are striking back at George Christensen, MP, who accused the BOM of “wiping” the official records of heat waves in 1896 and demanded an inquiry. For some reason, despite their world class work, Nicholls and Lewis still don’t seem keen on having an inquiry — so they go to some length to explain why it’s “false” to say it was hotter in 1896 than it was in 2013. Oddly though, to come to this conclusion they don’t use BOM work, because the BOM concluded “it would be very difficult to compare the 19th-century temperature data with modern observations.” Instead that difficult task was done by Berkley. Nichols calls it “brave”, but a “fact” at the same time.

        In their long article, what they don’t explain is why they almost never mention any of the hundreds of ultra hot historic temperatures in their press releases and national news. George was “wrong”, and that’s a “fact” we’re told, but most of their article on The Conversation explains why we don’t know what the temperature was in 1896. Try not to get confused…..

        Since some thermometers were older types called Glaisher or Greenwich Screens, their data is unusable, even though there are decades of temperatures comparing the two types of screens and they are remarkably similar.
        Even though Stevenson screens were installed across Australia between 1880 – 1910, since they were new (ahem), they were likely to be warped and cracked, and therefore not acceptable. After that date they were better maintained (except they still needed a lot of downward adjustment).

        There is a lot of data comparing older screens to newer ones. As Nicholls and Lewis mention:

        The results of this 61-year experiment show that summer daytime temperatures measured using the Glaisher Stand are, on average, 1C warmer than in the Stevenson Screen.

  12. Mikky says:

    AndyG55 and Steve, I have looked at all those places you mentioned, it would indeed be better to use comparison stations that are closer than Adelaide, but unfortunately they got themselves organised around 1908 and most show the same (or similar) steps down, but with enough of a time difference to “prove” that it was not climate.

    Ever since 1908 Deniliquin and Adelaide have tracked each other very closely apart from a very constant 1C (on average) difference. How could things have been so different before 1908? Changes to the systems in use is by far the most plausible explanation. Making appropriate shifts restores the close tracking of the stations before 1908, and before 1897/8 when there was another set of step changes.

    • AndyG55 says:

      Adelaide and Denny are in totally different climatic zone.
      If there were a consistent climate pattern of blocked wind movement over several years, like say in the Federation Drought, there is every possibility that the central parts of NSW would get a large build-up of heat.

      • Mikky says:

        The data (and the geography) does not support “totally different climatic zones”, in fact quite the opposite. Nearby ECHUCA should closely match Deniliquin if thermometers had been faithfully recording a build-up of heat, it doesn’t, it faithfully records a series of major system changes.

        Heat build-ups don’t last 20 years, and don’t remain confined to small areas, sheesh why are some sceptics of a changing climate so keen to hang on to a massively changing climate. Correcting early data from Oz gives an unchanging climate, what is not to like about that?

        • AndyG55 says:

          You were talking Adelaide and Deniliquin.
          Those were the ones I was saying were different.

          If there s sufficient data from Echuca, and those other places I mentioned to discount the large bulge before 1908 at Denny, then sure, I have no problem with that.

          But don’t use Adelaide.

        • AndyG55 says:

          What might be interesting would be to try to find rainfall data for Adelaide and Denny from 1890 – 1910.

        • Mikky says:

          Like I said, Adelaide is not perfect as a reference but it is the most suitable one, as most of the nearby stations were undergoing similar system changes. Actually there are a few nearby that appear not to have had changes around 1908 (Beulah, Wangaratta, Benalla), but they don’t have enough years before to be sure.

          Those other stations are “consistent with” the essentially non-changing-average-climate recorded at not-very-distant Adelaide.

        • Adelaide is warming four times faster than Caliph

        • AndyG55 says:

          Adelaide is NOT at all suitable for comparison with Deniliquin.

        • AndyG55 says:

          They are nearly 600km apart !!
          Adelaide is right on Gulf St Vincent. The Southern Ocean.
          Denny is in the lower central west of NSW.
          They are affected by very different climate patterns.

          Next you will want to compare San Francisco with Las Vegas or something !!

        • Mikky says:

          The climate differences you mention certainly do apply to Melbourne, but if you plot Adelaide and Deniliquin on the same graph you see remarkable similarity, every peak and trough matching. Data trumps theoretical hand-waving. Are you saying that it never gets hot in Adelaide?

          A longer process of correction would be to move out from Adelaide, first correcting Mildura, Broken Hill and Kerang, then using them to correct Hay and Deniliquin, but ALL of these have the same “shape”, proof that one can go directly from Adelaide.

  13. AndyG55 says:

    And in Australia, climate patterns can last for several years.

    From 1880 – 1903 there were two major droughts, in central NSW-Vic with a small respite between.

    Click to access 2004-11-drought.pdf

    Long droughts lead to loss of local water and hence the loss of local cooling effect.

    Adelaide would always have the local cooling effect of the ocean.

    Sorry, but your comparison of Denny with Adelaide is not very persuasive at all.

  14. AndyG55 says:

    A bit of research confirms that the Edwards/Murray Rivers near/through Deniliquin did run dry during the Federation drought.

    The loss of these bodies of water would have cause a big loss of the cooling effect.

    Here is some reading for you.

    • Mikky says:

      The Federation Drought years remain in the corrected data, but only at the level of an extra 0.5C (in the averages), not at a level of 3C.

  15. AndyG55 says:

    Oh and the town’s highest temperature of 49.5 °C (121 °F) was reached on 12 January 1878 and is one of the highest ever recorded in Australia.
