Explain this? Rutherglen homogenized with 17 stations including Hillston!

We’ve seen the remarkable change of the Rutherglen record as it got homogenized. This long running rural record that looks ideal apparently had “unrecorded” station moves found by thermometers miles away. Already we have found Bill Johnston who did some work at Rutherglen who confirmed that the station did not move. The mystery grows?

Since early 2012 Ken Stewart has been asking the BOM which neighbouring stations were used. Finally, after pressure from The Australian, the BOM has provided the 17 names, and Ken has graphed them.

Follow the chart below. Rutherglen temperatures start off in blue. The yellow line is the average of the 17 “neighbours” which are used to homogenize that blue line and transform it into the red one which somehow ends up being colder than its neighbours in 1952 and warmer than its neighbours in all the last 30 years.

See if you can figure it out?

Rutherglen starts off blue. Then the yellow line is used to homogenize that blue line into the red one.

Presumably the BOM technique would be a lot more complicated that what Ken has done, but clearly replicating that ACORN final trend is not going to be easy.

Threat of ANAO Audit means Australia’s BOM throws out temperature set, starts again, gets same results

Joanne Nova and Ken Stewart

A team of independent auditors, bloggers and scientists went through the the BOM “High Quality” (HQ) dataset and found significant errors, omissions and inexplicable adjustments. The team and Senator Cory Bernardi put in a Parliamentary request to get our Australian National Audit Office to reassess the BOM records. In response, the BOM, clearly afraid of getting audited, and still not providing all the data, code and explanations that were needed, decided to toss out the old so called High Quality (HQ) record, and start again. The old HQ increased the trends by 40% nationally, and 70% in the cities.

So goodbye “HQ”, hello “ACORN”. End result? Much the same.

That meant the ANAO could avoid an audit, since the BOM had changed data-sets, the point of auditing the old set was moot.

For me, this version is so much worse than the previous one. In the HQ data set the errors could have been inadvertent, but now we’ve pointed out the flaws, there can be no excuses for getting it wrong. Instead of fixing the flaws (and thanking the volunteers), it’s almost as if they’ve gone out of their way […]

Horrifying examples of deliberate tampering

Just when you thought it couldn’t get worse for the cult of the carbon scare.

Now we need to ask if the world has even warmed? I’ve always said, “global warming is real”, but the recent exposés of shocking corruption in science have made me start to wonder whether even that is true.

Today a study by Joe D’Aleo and Anthony Watts, was announced by the Science and Public Policy Institute (SPPI).

From their media release:

An extensive survey of the literature and data regarding ground and sea surface temperature records uncovers deception through data manipulation, reports the Science and Public Policy Institute (SPPI).

Authors veteran meteorologists Joe d’Aleo and Anthony Watts analyzed temperature records from all around the world for a major SPPI paper, Surface Temperature Records – Policy-driven Deception? The startling conclusion that we cannot tell whether there was any significant “global warming” at all in the 20th century is based on numerous astonishing examples of manipulation and exaggeration of the true level and rate of “global warming”.

That is to say, leading meteorological institutions in the USA and around the world have so systematically tampered with instrumental temperature data that it […]
