Bottom line: The BOM has
added a page listing “Adjustments”. It’s two years late, inadequate and
incomplete. Skeptics shouldn’t have had to ask for it in the first
place, and we still don’t have the algorithms and codes, or rational
answers to most questions. No one can replicate the mystery black box
homogenisation methods of the BOM — and without replication, it isn’t
science. There is still no explanation of why an excellent station like
Rutherglen should change from cooling to warming, except for vague
“statistics”, or why any station should be adjusted without documentary
evidence, based on thermometers that might be 300 km away.
Lo and behold, the pressure from
The Australian and
independent analysts means the BOM has made a weak belated attempt to do
what it has implied it always has done. When Michael Brown
provided cover for the BOM he said the notion that scientists were hiding data was “pseudoscience”. The BOM, meanwhile, added a page called
“Adjustments”,
two years after launching “ACORN”, quietly admitting that the skeptics
were right. They did not correct Brown’s baseless namecalling. Other
apologists for their
inexplicable anomalies,
major adjustments or
errors –
like David Karoly — demand the skeptics publish in the peer reviewed
literature before they will even consider their point of view, but
neither Karoly nor the BOM can name the peer reviewed document, or any
publication or link, with the
full homogenization code. How can
skeptics discuss a method in the peer review literature which is not
publicly available? The BOM homogenization technique remains a black box
method that cannot be replicated — only the secret guild of anointed
BOM staff are privy to the details.
Let’s open that BOM black box: let’s have a replication of the
homogenization process, open to public inspection, so it can be audited.
So everyone can see where every homogenized number came from, back to
the raw data and the adjustments. No public company could shield its
finances from observation like this: they have to produce audited
accounts every six months that show all money in the company bank
account, all money owed, and all money owing.
All of it.
And once we have replication,
then we can have an informed
discussion of the ramifications of the current homogenization process,
and how it might be improved or made more realistic."
