Australian temperatures plunge after BOM orders fix

Weather stations were programmed to put a limit on how low temperatures could be recorded in official weather data.

Excerpts from an article by Graham Lloyd in The Australian on August 4:

“The BoM (Bureau of Meteorology) said it had taken immed­iate action to replace the Thredbo station (and several other stations) after concerns were raised that very low temperatures were not making it onto the official record. Controversy has dogged the bureau’s automatic weather station network since Goulburn man Lance Pigeon saw a -10.4C reading on the BoM’s website on July 2 automatically adjust to -10C, then disappear.

“BoM initially claimed the adjustments were part of its quality control procedures. But bureau chief executive Andrew Johnson later told Environment Minister Josh­ Frydenberg that investigations had found a number of cold-weather stations were not “fit for purpose” and would be replaced.

“It has been reported online that electronic smart cards were allegedly fitted to the BoM’s automatic weather stations, which put a limit on how low temperatures could be recorded in official weather data.

“On her website yesterday, Dr Marohasy said it was not the recording­ devices that were at fault. “To be clear, the problem is not with the equipment; all that needs to be done is for the smart-card readers to be removed,” Dr Marohasy said.”

  1. I read this some time ago now, there was no “plunge” in temperatures documented. The arbitrary censoring however was an extraordinarily egregious policy. However,+/- 0.4 C change is not much to be excited about. It’s equal +/- 0.72 F. So, less than a degree Fahrenheit. The real issue is how much real information beyond that 0.4 C was censored. That is a real problem.

    1. if .4 of a degree isnt an issue?
      then pray tell how a Miniscule one TENTH of a degree from “massaged” numbers was enough to have the agw lobby screaming blue murder hottest EVAH year last yr???
      so YES even that point FOUR lower does actually matter..
      even if its just to highlight the rather weird and devious preset lowest temp setting INTENTIONALLY!
      and saying its the cards at fault?
      well someone authorised the presets and also WOULD have had access to the OLD realtime cold records before making a decision
      theres a lot to be said for people using old methods of go and LOOK and record
      way too much opportunity for fudging n f’ing things over using distance n techie tricks.
      as even our extreme biased abc news services had to admit today
      theres a LOT of money being made BY the weather forecast mobs and apps and services etc
      follow the money as always!

      1. Neither is a 0.1-degree C. The information lost is immensely more important than any single 0.4 C. Because of that censoring, the real range of temperature during the period the censoring system was active is unknown. All the handwaving the BOM indulges in can’t alleviate the reality that it had stations set to censor data “that was too low.” It could have been more than a degree and for how many days? All that was NOTED was 0.4 degree C. The single known change isn’t important. Over 365 days it would count for nothing. But the practice now, THAT is a problem. And there is no problem free way of collecting data. If you look into old weather station records there are frequently edits, handwriting that is illegible, and just plane holes where somebody forgot, couldn’t, etc. Fiddling data is nothing new in science or even in more critical pursuits like architecture and doing it with architecture can be lethal.

    2. It is something to get excited about 0.4 degC is enough to align the models with the amount of change they pretend to show over one hundred years. You are aware that national services cry tears about increase of a few 1/100 of a degree, no?

      We are also not sure it was only 0.4 degrees were taken off since the -10.4 and the -10 were taken off the record. Seems like it could be worse than you are claiming.

    3. 0.4 Degrees C is not insignificant, considering that global “record temperatures” announcements use decimals of a degree.

    1. That really is important. Also, what was the purported justification? Some one asked for and received tax money from Australia’s citizens to buy, program and install those cards.

  2. Every hoax must be propped up along its journey to infamy.
    That’s what the warmists are doing in Australia. This is the next step in climate fraud — falsifying data at the collection point. Hoaxers, in the tradition of M. Mann, now have no algorithm to reveal allowing them to claim—-this is the raw temperature data, wink, wink!
    Apparently BOM has either hired ex VW engineers responsible for the diesel emissions scandal or a group of thieves scanning our credit card numbers at gas stations—Which is it BOM? ANYONE having ANYTHING to do with this FRAUD should be FIRED IMMEDIATELY!!!!!!!!!!!!!!

  3. when the hype over anthropogenic global warming is over a proposed 0.2C, then that 0.4C adjustment is HUGE!!!!

    Recall, the trillions of dollars are expected to be spent in order to limit humanity’s growth, humanity’s access to energy, and humanity’s technological revolutions is over a proposed 0.2C increase over the next 100 years.

  4. I have always wondered what effect the demise of the Soviet Union had on global warming data.

    Perhaps hundreds of weather stations in one of the coldest locations on Earth probably ceased reporting. There was no money to pay for non essential things like recording temperatures and there was no longer any centralised authority to report to.

    Remove a significant number of colder temperature records from a data set and the result is an artificial warming – kinda like what BOM is seemingly accused of.

    The Soviets would have had meticulous records prior to the collapse and I suspect almost none after and I assume the result was an artificial warming trend in the datasets of the reporting authorities simply because a lot of cold temperature records were missing from the early 90’s on.

  5. Climate scientists who are global warmists are committing fraud its that simple and its suits govt because they can rip off the people with taxes ….. eg increased GST on energy bills. People that have been sucked into this fraud consider its their duty to pay more taxes on energy. Many hard up citizens are coping it hard.
