Australia’s Bureau of Meteorology ‘adjusting’ temperature data to fit their narrative

In a previous post, I highlighted how NASA had re-written the historic temperature data series to reduce historic heat. The effect of this is to amplify the current heat, implying temperature increases that aren’t in the data record.

Jo Nova has demonstrated that the Australian BOM has now been shown to use the same practice. Prior to 2011, their website showed no change in the number of very hot days since 1910. In 2011, they adjusted the historic data downwards, with the result of an apparent increase in very hot days. This wasn’t sufficient, so they did it again in 2018. Unfortunately of them, the historic data is still on record. The graphs are as follows:

Pre-2011 record
2011-2017 record
Current record, 2019
