JoNova(Australia)
Billions of dollars, climate models, predictions, and hundreds of
press releases depend on the BOM records of Australian temperatures.
There were so many inconsistencies, inexplicable adjustments and errors
that we put in a Senate request for the ANAO to audit the records. In response, to dodge the audit, the BOM dumped its HQ (“high quality”) dataset entirely, and established a new “best practise” ACORN dataset.
Independent volunteer auditors have been going through the ACORN
records — thanks especially to Ken Stewart who is publishing his
findings on his site as he works through the set. He’s analyzed 84 out
of 104 sites, and finds that ACORN is just as bad as the HQ set. At Kenskingdom
he shows that so far, the adjustments used to create the official
Australian temperature record increase the warming trend by13% for
maxima and a whopping 66% for minima. (Note the caveats in the
conclusions below.)
The raw Australian data suggest the nation warmed by 0.6 °C over the last century. The BOM adjustments lift that to 1.05 °C."
