The Australian BUM explains


Here’s the BOM explanation:

“Amberley: the major adjustment is to minimum temperatures in 1980. There is very little available documentation for Amberley before the 1990s (possibly, as an RAAF base, earlier documentation may be contained in classified material) and this adjustment was identified through neighbour comparisons. The level of confidence in this adjustment is very high because of the size of the inhomogeneity and the large number of other stations in the region (high network density), which can be used as a reference. The most likely cause is a site move within the RAAF base.”

Translated:So the Amberley thermometer might have secretly moved (and that might be classified) but we are sure it shifted one way or the other. Even though we don’t know where it was before, or how much difference that makes, we can figure out what the thermometers should have been recording in 1941 because of other stations which are hundreds of kilometers away.

Oops

Even more strange is that the nearest ACORN station is Brisbane Aero, 50km away, which also shows a long term cooling trend. (Paul Homewood has some good graphs on that.) It seems other stations further away are better at recording Amberley temperatures than thermometers at either Amberley or Brisbane.

Expert team plans to examine 'adjusted’ temperature data

How did we know that 2014 was “the hottest year ever”? This was based entirely on surface temperature data originally compiled by the US Global Historical Climate Network (GHCN), but then translated into their own versions by the compilers of three of the five official temperature records. But as I explained in two previous articles, a growing number of experts across the world have been discovering that something very odd has been going on with these records. Again and again they found that, checking them against the raw data originally recorded by weather stations, this had then been comprehensively “adjusted”, almost invariably in the same direction.


Earlier data had been “adjusted” downwards, more recent data upwards, to show much more of a warming trend than the actual recorded temperatures justified. Often, as Paul Homewood demonstrated on his Notalotofpeopleknowthat blog – after checking many weather stations in South America and across the Arctic – a cooling trend over the past century had been transformed into a warming trend.

If the results confirm what has already been unearthed by Homewood and other analysts, from the US to New Zealand, this may indeed turn out to have been the greatest scandal in the history of science.

Yes indeed the greatest scandal in the history of science

Almost as great as the evolution scandal. Almost.

Well admittedly finding bias in an author who says its all a scam is pretty good
