IN September 2017, the Australian Bureau of Meteorology (BoM) claimed a series of new record hot days across south eastern Australia, including on 23 September at Mildura. At that time, the mainstream media reported this as a new record for the state of Victoria, specifically claiming it was the hottest September day ever recorded – […]
Sunday, 12th November 2017 – 4PM Honourable Josh Frydenberg MP Minister for Environment and Energy Dear Minister Re: Suspend announcement of new record hot days – Inform WMO that Bureau’s measurements are currently not comparable with mercury thermometers – Give directive for release of more A8 forms – Establish an audit mechanism 1. BACKGROUND I […]
FOR some time, weather enthusiasts across Australia have been noticing rapid temperature fluctuations at the ‘latest observations’ page at the Australian Bureau of Meteorology’s website. For example, Peter Cornish, a retired hydrologist, wrote to the Bureau on 17 December 2012 asking whether the 1.5 degrees Celsius drop in temperature in the space of one minute […]
Following is the latest advice from the Australian Bureau of Meteorology regarding measurement of temperatures from automatic weather stations (AWS). This advice contains numerous errors of fact and is inconsistent with the information in an internal review issued just last Thursday. The following misinformation has just been posted at the official Bureau website: http://www.bom.gov.au/inside/AWS_Review_Fast_Facts.pdf My […]
He studied chemistry at Imperial College, London, has 10 degrees, including a law degree, and has published more than 100 scientific papers. I’m referring to my husband, John Abbot. He is also a man of few words. Last Friday morning, after flipping through the Australian Bureau of Meteorology’s latest 77-page internal report – Review of […]
TWO decades ago the Australian Bureau of Meteorology replaced most of the manually-read mercury thermometers in its weather stations with electronic probes that could be read automatically – so since at least 1997 most of the temperature data has been collected by automatic weather stations (AWS). Before this happened there was extensive testing of the […]
THE Bureau has a network of 695 automatic weather stations (AWS) across Australia. In a report released late yesterday it acknowledged issues with the performance of just two of these: Goulburn Airport (Goulburn) and Thredbo Top Station (Thredbo). These are the same two weather stations that I reported at my blog were not recording temperatures […]
Because a change in equipment can potentially create discontinuities in a temperature record, it is Australian Bureau of Meteorology policy to have new equipment recording side-by-side with old equipment for a period of at least 2 years. In this way, readings from the new equipment can be compared with readings from the old equipment, including […]
Australia is a large continent in the Southern Hemisphere. The temperatures measured and recorded by the Australian Bureau of Meteorology contribute to the calculation of global averages. These values, of course, suggest catastrophic human-caused global warming. Two decades ago the Bureau replaced most of the manually-read mercury thermometers in its weather stations with electronic devices […]
AFTER deconstructing 2,000-year old proxy-temperature series back to their most basic components, and then rebuilding them using the latest big data techniques, John Abbot and I show what global temperatures might have done in the absence of an industrial revolution. The results from this novel technique, just published in GeoResJ [1], accord with climate sensitivity […]
