Australian Bureau of Meteorology altering historical temperature records
The BOM has shortened and altered the historical temperature record for Darwin, Australia. The BOM is no longer using data between 1894 and 1909. They are starting the record at 1910 as this is when an automatic weather station was installed at the Darwin Airport.
The raw data temperature measured on Jan 1st 1910 was 34.2C. A few years ago, the Bureau changed this to 33.8C, cooling the recorded temperature by 0.4 degrees. In its most recent re-revision of Darwin’s climate history the temperature on this day has been further reduced, and is now just 32.8C.
A spokesperson said :
For the case of Darwin, a downward adjustment to older records is applied to account for differences between the older sites and the current site, and difference¬s between older thermometers and the current automated sensor.
In other words, the adjustments estimate what historical temperatures would look like if they were recorded with today’s equipment at the current site.
Yet this is what they said the first time they changed it a few years ago. These fuckers are making the past colder to look like we are increasing in temperature.
