Australian temperature records shoddy, inaccurate, unreliable. Surprise!

The BOM say their temperature records are high quality. An independent audit team has just produced a report showing that as many as 85 -95% of all Australian sites in the pre-Celsius era (before 1972) did not comply with the BOM’s own stipulations. The audit shows 20-30% of all the measurements back then were rounded or possibly truncated. Even modern electronic equipment was at times, so faulty and unmonitored that one station rounded all the readings for nearly 10 years! These sloppy errors may have created an artificial warming trend. The BOM are issuing pronouncements of trends to two decimal places like this one  in the BOM’s Annual Climate Summary 2011 of “0.52 °C above average”  yet relying on patchy data that did not meet its own compliance standards around half the time.  It’s doubtful they can justify one decimal place, let alone two?

We need a professional audit.

 

A team of independent engineers, scientists, statisticians and data analysts (brought together by the joannenova blog) has been going through the Australia Bureau of Meteorology records (BOM). They’ve audited some 8.5 million daily observations across 237 High Quality and other close sites in Australia. Shockingly, while [...]

Announcing a formal request for the Auditor General to audit the Australian BOM

A team of skeptical scientists, citizens, and an Australian Senator have lodged a formal request with the Australian National Audit Office (ANAO) to have the BOM and CSIRO audited.

The BOM claim their adjustments are “neutral” yet Ken Stewart showed that the trend in the raw figures for our whole continent has been adjusted up by 40%. The stakes are high. Australians could have to pay something in the order of $870 million dollars thanks to the Kyoto protocol, and the first four years of the Emissions Trading Scheme was expected to cost Australian industry (and hence Australian shareholders and consumers) nearly $50 billion dollars.

Given the stakes, the Australian people deserve to know they are getting transparent, high quality data from the Bureau of Meteorology (BOM). The small cost of the audit is nothing in comparison with the money at stake for all Australians. We need the full explanations of why individual stations have been adjusted repeatedly and non-randomly, and why adjustments were made decades after the measurements were taken. We need an audit of surface stations. (Are Australian stations as badly manipulated and poorly sited as the US stations? Who knows?)

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 [...]

The main “cause” of global warming is air conditioners. p7

The headline is tongue in cheek, but the message is serious.

Look at these pictures of NOAA’s U.S. temperature stations. These thermometers on the ground have recorded faster temperature rises than sensors on satellites and weather balloons.

Lucky heat doesn’t rise off asphalt…

Things may have looked different at this site in 1909.
