They have remodelled Australia’s official temperature record for the third time in nine years.
To the surprise of nobody with their finger on the pulse, the Bureau found things to be warmer than thermometer readings had measured.
More specifically, the Bureau added 0.06C to maximum warming and 0.11C to minimum warming from 1910-19 to 2010-19. They also added 0.228C mean temperature warming if comparing 1910-19 with 2010-17.
Researcher and journalist, Chris Gillham, said the impact of adjustments to ACORN versions 1, 2, 2.1 and 2.2 was to cool the past and warm the present.
Of course, the Bureau declined to comment.
Scientist Jennifer Marohasy, an outspoken critic of the Bureau’s manipulation of climate data said: “I have shown repeatedly, including in peer-reviewed publications, that without scientific justification historical temperatures are dropped down, cooling the past. This has the effect of making the present appear hotter – it is a way of generating more global warming for the same weather.”
Dr Marohasy said the daily maximum and minimum values in the national temperature dataset were different from the actual recorded historical value, often by several degrees, usually cooler.
“The bureau has now remodelled the national temperature dataset three times in just nine years,” Dr Marohasy said.
