This is a real scandal. The Australian Bureau of Meterology (BOM) changed the past temperature record twice, ‘cooling the past.’ But, in reality, if you look at their raw official data, it is plain to see that there has been no more hot days in Australia than usual. The data goes back to at least 1910.
The following video reveals how the past Australian temperature record has been ‘cooled’ by at least 1.5 degrees C (or 3 degrees F) in two separate revisions. That means scientists changed the values of past temperature records before the 1990s. The effect is that it artificially makes it appear that the past few decades have been hotter than any decade prior to that time. This gives the appearance that the country has been hotter in recent times. But that claim is totally false.
The big scandal here is two fold. Firstly, the fact alone that current scientists think that they can legitimately tamper with past temperature records. The second is much more significant. How do you know that what you decide on regarding the past (when no one has access to the past) is in any way accurate? Simply put, you can’t know.
No one has a time machine. No one can know what happened in the past. No scientist, no matter matter how smart he thinks he is can know what happened in the past. The best you can do is to rely on a record of an observer who recorded something at some past moment of time. You have to take that record on its face value. You can’t measure anything that happened in the past.
This is why we have official birth certificates. It was the observers present at your birth that essentially testify, in an official document, that you were born at such a time and on such a date. They were there. Some future scientist, who was not there, can’t later correct that record.
The past Australian temperatures were usually recorded at Post Offices and they were recorded in official notebooks. Those notebooks are kept in the National Archive. But now we have modern day scientists who claim to know better and, under the excuse of ‘homogenising’ the data, they have changed the past temperatures, and ‘cooled’ it is all cases. So the alleged ‘real’ temperatures as recorded in the notebooks were in error, i.e. they all allegedly had some systematic error.
What they are claiming is that, because electronic (PRT) thermometers were introduced in the 1990s, the prior measurements made with Mercury thermometers did not have the same calibration as the modern PRTs. But fallible humans with a global warming bias are the ones who changed the historical records. And who would doubt their bone fides in doing that? And the problem, as you can plainly see, is the weakness of historical science. It’s all very Orwellian to say the least.
