Translated: We are careful people, “trust us” Despite Amberley being a good station (as far as anyone can figure) it was adjusted to fit “neighbours” hundreds of kilometers away: ‘BOM said the adjustment to the minimums at Amberley was identified through “neighbour comparisons”.
It said the level of confidence was very high because of the large number of stations in the region.
Do the headlines of “hottest ever record” (reported to a tenth of a degree) mean much if thermometer data sometimes needs to be dramatically changed 60 years after being recorded?
One of the most extreme examples is a thermometer station in Amberley, Queensland where a cooling trend in minima of 1C per century has been homogenized and become a warming trend of 2.5C per century.
(See Ken’s Kingdom) NASA’s Goddard Institute also adjusts the minima at Amberley up by homogenization with other stations.
But the radius of those stations is nearly 1,000 km.
There were examples where homogenisation had resulted in a weaker warming trend.
Amberley is near Brisbane which also shows a cooling raw trend, though other neighbours like Cape Moreton Lighthouse, Bundaberg, Gayndah, Miles, and Yamba Pilot Station have an average warming trend.
“In (George Orwell’s) Winston Smith knows that, ‘He who controls the present controls the past’.
Certainly the bureau appears intent on improving the historical temperature record by changing it,” Marohasy says.
There is both a feature and a news piece today in Both Jennifer Marohasy and Graham Lloyd are both doing great work here: The Australian THE Bureau of Meteorology has been accused of manipulating historic temperature records to fit a predetermined view of global warming.
