This is exactly the type of thing that the Australian Government is desperately trying to stop David Icke exposing
'A report in The Australian has warned that the integrity of Australia’s historical temperature record is being challenged after the Bureau of Meteorology (BoM) updated its temperature records for the second time in six years.
The report cited environmental scientist Jennifer Marohasy who questioned how BoM could have released an updated dataset called ACORN-SAT version 2 in October 2018 that “generated a 23 percent increase in the rate of warming, just through updating the official ACORN-SAT record.”
Marohasy shared a table comparing raw temperature readings and the two “homogenised” ACORN-SAT datasets, explaining that the data corrections have resulted in a “rewriting” of the temperature records of 112 weather stations dating back to 1910. ACORN-SAT stands for the Australian Climate Observations Reference Network—Surface Air Temperatures.
“Temperatures are changed through a process known as homogenisation, and then changed again, sometimes by as much as 6.4 degrees Celsius (11.5 F) for the one day,” Marohasy said in a blog post.

According to Marohasy, 44.8 degrees Celsius (112.6 F) was the maximum temperature measured at Albany, Western Australia, on Feb. 8, 1933. In the year 2012, BoM homogenised the maximum temperature to 51.2 degrees Celsius (124 F), before it was recently revised to 49.5 degrees Celsius (121.1 F).
While various accounts have revealed that it is not unusual for weather bureaus to change temperature records—New Zealand’s National Institute of Water and Atmospheric Research (NIWA) was involved in a court battle with climate skeptics who claimed that scientists had taken raw temperature records and adjusted them resulting in warming trend—Marohasy questioned the rationale behind the scale of the homogenisation applied to the Albany records on Feb. 8, 1933.'
