AUSTRALIAN MET OFFICE ACCUSED OF MANIPULATING TEMPERATURE RECORDS
Linking article: Australia Government Climate Office Accused Of Manipulating Temperature Data
Dr. Jennifer Marohasey claims the BOM’s adjusted temperature records are “propaganda” and not science, according to the Australian. Marohasey said she analyzed raw temperature data from places across Australia and compared them to BOM data.BOM claims that the data needed to be "homogenized" to account for changes in practices, instrumentation, etc. over the last 100 years. However, the homogenization meant that recent temperatures had to be consistently increased, even if no need could be shown for those changes.
The result: the BOM’s adjusted data creates an artificial warming trend. Marohasey said BOM adjustments changed Aussie temperature records from a slight cooling trend to one of “dramatic warming” over the past century.
BOM has rejected Dr Marohasy’s claims and said the agency had used world’s best practice and a peer reviewed process to modify the physical temperature records that had been recorded at weather stations across the country."Peer review" here is useless. Group-thinkers have to group-think. This is what politicized scientist expect to find and they "found it."
"Best practice" here is again useless. Is it best practice to decrease temperatures from early in the century and increase them late in the century to create a warming trend of 2.5 degrees per century? And to create one out of data that shows a slight cooling trend?
Dr Marohasy said she had found examples where there had been no change in instrumentation or siting and no inconsistency with nearby stations but there had been a dramatic change in temperature trend towards warming after homogenisation.Various people have noted that NOAA in the US has done the same thing with its data.
She said that at Amberley in Queensland, homogenisation had resulted in a change in the temperature trend from one of cooling to dramatic warming.
She calculated homogenisation had changed a cooling trend in the minimum temperature of 1C per century at Amberley into a warming trend of 2.5C. This was despite there being no change in location or instrumentation.
