Since the installation of an automatic weather station at Thredbo, there has been a reduction in the number of days each year when the temperature has fallen to, or below minus 10.0 degree Celsius - from an average of 2.5 (1966 to 1996) to 1.1 days (1997 to July 2017).   As a matter or urgency, the Bureau needs to explain when the limits were placed on the minimum temperature that could be recorded at this, and other,  automatic weather stations.

Four-Steps Needed to Restore Confidence in Bureau’s Handling of Temperature Data

THE Minister for Environment and Energy, Josh Frydenberg, needs to immediately instigate the following four-step process to restore confidence in the recording and handling of historical temperature data. Step 1 – Instruct the Bureau to immediately: 1. Lift any limits currently placed on the recording of minimum temperatures; 2. Make publicly available the dates on […]

Remembering Diane Ainsworth

I can’t find a good photograph of Diane Ainsworth – one that does her justice. Thirty years ago, she had a cheeky smile, deep-set eyes, mousey-coloured thick wiry hair, and a very thin waist. We were friends at boarding school, and in the same hockey team: I was the centre-forward and she my fast and […]

Bureau of Inconsistencies: Need for Urgent Independent Inquiry

MINISTER Josh Frydenberg was told by the Australian Bureau of Meteorology on, or about, Wednesday 5th July 2017 that limits had been placed on how cold temperatures could be recorded across mainland Australia. This winter we have experienced record low temperatures.   But only the keenest weather observers have noticed, because the Bureau has been changing […]

Bureau Misleads Minister Frydenberg on Goulburn

RATHER than admit that temperature dropped to a record low -10.4 degree Celsius on the morning of Sunday 2nd July at Goulburn, the Bureau of Meteorology has come-up with yet another even more absurd story. Responding to a letter from Josh Frydenberg, the Minister for  Environment and Energy, Andrew Johnson, CEO and Director of Meteorology, […]

Skilful Monthly Rainfall Forecasts

THE accurate weather forecast of James Stagg back in June 1944 is considered crucial to the successful D-day invasion that changed the course of WWII. Should we find ourselves at war again, is there an institution or individual capable of providing an accurate short or long-term weather forecast? Dr John Abbot and I are working towards […]

Bureau Still Limiting Cooling to Minus 10 Degrees

TWO weeks ago, in response to my queries the Australian Bureau of Meteorology acknowledged that it had put in place limits on the lowest temperature that an individual weather station could record.  So, when the automatic weather station which now operates in the town of Goulburn (not far from Canberra), recorded a measurement of minus […]

In Search of a New Way

FIFTY years ago, on 7 July 1967, Time magazine ran a cover story entitled, ‘The Hippies: Philosophy of a Subculture’.   Modern environmentalism is in some ways a product of this Flower Power movement, but a still-born version. It has become replete with particular moral codes – right ways of doing things – ostensibly underpinned by a […]

Bureau Now Sets Strict Limits on Cooling

OVER recent years I have documented the blatant remodelling of temperature measurements through the process of homogenisation. I have explained that it is the homogenised datasets that are used to report climate change by the Australian Bureau of Meteorology and the CSIRO.   I had assumed, however, that the raw data, kept in the CDO dataset, […]

Climate Change: The Facts 2017

Today’s Weekend Australian includes an article that begins: “Iconic, ailing Australian satirist Clive James has penned a savage essay on climate change alarmism, controversially cooking everyone from Barack Obama to Kevin Rudd to Tim Flannery to Al Gore to Donald Trump in the boiled and rising ocean of his wit…” The essay in The Inquirer section […]
