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.
The original audit was about the adjustments. Sidestepping that audit with new adjustments still doesn’t explain the adjustments that say warming to raw data that says no warming. The raw data- actual observation – must be preserved and considered objective. (I know, more of the same.)
Once they understood that they’d been caught out adjusting recent temperature records up to show modern warming that wasn’t happening, they had to come up with a way to create an appearance of warming without making too many large adjustments to the recent record. If there’s no significant warming in the recent record, the simplest way to get the same result is to adjust the older record down to get the same rate of warming without being quite so obvious about it. It’s good to see that some of our Aussie friends have been paying attention and have caught them red-handed. Congratulations to those standing for science and truth.
