JoNova(Australia)
The BOM announced it was the hottest ever day in Sydney today, then
realized it had it wrong, but not before headlines spread across the
country. For a million dollars a day you’d think the BOM would check
their own “high quality” database. A scientific agency would take great
care before announcing “historic all time records”for a city of five
million people. A shameless PR agency might see that sort of mistake as
an advantage.
It’s careless, piled on rank neglect
Even if the day had been “a record”, the temperatures are often
artificially inflated due to
site changes, thermometer changes, and the
one-second-record effect thanks to the introduction of
electronic thermometers, all of which are a product of careless BOM management and analysis. And even over and above that, past temperatures have been
adjusted or
homogenised downwards — often years after they are recorded — and by secret methods that the
BOM will not disclose. I’ll have more information soon on changes at Sydney Observatory, that the BOM don’t make any allowance for."
