We, the Australian public, are regularly informed by the Australian Bureau of Meteorology that international temperatures have to be restricted to inside 1.5C above the pre-industrial period. Additional the Bureau attributes the ‘dramatically elevated fee of noticed scorching file breaking in current Australian temperatures’ to human-caused international warming.
However what if at the very least a few of this warming was pure, and what if the opposite element may very well be attributed to how the temperatures are actually recorded – with probes in digital climate stations changing mercury thermometers – after which there may be the remodelling by way of the method of homogenisation.
To some extent the Bureau paperwork the extent of the remodelling that has the technical title homogenisation, however the Bureau has by no means made public the extent of the discrepancy between temperatures as recorded from mercury thermometers versus the brand new digital automated climate stations.
Work that I’ve undertaken with John Abbot exhibits that even with out the commercial revolution there would have been a temperature enhance of about 1C by way of the twentieth Century.
The restricted parallel information that I secured from the Bureau, following the intervention of Josh Frydenberg again in 2017, exhibits that the probe inside the automated climate station typically information 0.4C hotter than the mercury thermometer for a similar climate.
The AAT listening to on Friday is about the necessity to make the parallel information public, so we are able to know the way a lot of current warming will be instantly attributed to the change in how temperatures are measured.
And for these wishing to attend the AAT listening to, particulars are:

The characteristic picture was taken by Craig Kelly and options in an article in at present’s The Every day Telegraph by Clarissa Bye entitled ‘Bit scorching and bothered? BoM silent on suspect photo voltaic panel shift’. It quotes me querying why the BoM briefly positioned a photo voltaic panel close to the climate station for Sydney Observatory, particularly when it appeared this climate station was recording a run of file cool days.
