Sydney “hottest ever” mistake generates fake news

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."
