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 […]
I have been chatting off-and-on with Peter Ridd, now Professor of Physics at James Cook University, for nearly two decades. We both resent the lack of honesty in the reporting of many environmental issues. Earlier this week, Prof Ridd was concerned that his recent comments to Sid Maher at The Australian newspaper [1], and then […]
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 […]
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 […]
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 […]
