The head of the Bureau of Meteorology, Andrew Johnson, has been asked by Environment Minister Josh Frydenberg to release extensive temperature data from a weather station in Victoria after requests from an independent scientist… so writes Sam Buckingham-Jones in The Australian newspaper.
The article goes on, “Late last month, Dr Marohasy, who also works at the Noosa-based Climate Lab, wrote to Mr Frydenberg expressing her concerns that the bureau’s electronic weather station equipment had been recording temperature data using a method that did not comply with World Meteorological Organisation guidelines.
‘The Australian Bureau of Meteorology appears to have put in place a measurement system guaranteed to provide new record high and low temperatures,’ she said in the letter.

I wrote the following two statements down on a scrap of paper when I was an undergraduate at the University of Queensland in the early 1980s. They seemed to resonate more with me as each year passes:
1. Belief in the truth of a theory is inversely proportional to the precision of the science.
2. The creativity of a scientist is directly proportional to how much [s]he knows, and inversely proportional to how much [s]he believes.

I moved to Noosa, in southeastern Queensland, a few years ago. In 2015, I established the Climate Modelling Laboratory to progress my work with John Abbot developing a technique for monthly rainfall forecasting using artificial neural networks: a form of artificial intelligence/machine learning/big data analytics – finding patterns, building models, projecting foreward, measuring the model’s skill at forecasting.
As well as interrogating large datasets, I enjoy swimming in the ocean, yoga, meditation and the occasional walk in the rain. My heros include William of Ockham, Thomas Huxley, Clement Wragge and Emile du Chatelet.
For a list of my papers on rainfall forecasting and temperature reconstructions click here; a more comprehensive list of scientific publications is click here. Over recent years I have been published in: Atmospheric Research, Advances in Atmospheric Research, Wetlands Ecology and Management, Human and Ecological Risk Assessment, Public Law Review and Environmental Law and Management.
I was published every fortnight for about 10 years by The Land newspaper, Fairfax Media Ltd (April 2004 – November 2014). I resigned as columnist, and also stopped regularly blogging, to concentrate more on my scientific research.
The skill of our forecasts can be measured in terms of root mean square errors (RMSE) and mean absolute error (MAE) relative to observed rainfall. This means that our forecasts could be easily compared in a rigorous and quantitative way against the forecasts from general circulation models including the Bureau’s POAMA. However, so far, the Bureau has resisted any comparisons being made, as I detailed in a letter to Simon Birmingham in August 2014, which can be downloaded here. The skill of our rainfall forecasts is affected by the quality of the temperature series inputted as part of multidimensional arrays, which is why I have become somewhat vocal about the often ad hoc process of homogenization undertaken to temperature series by the Bureau.
I am also a senior fellow at the Institute of Public Affairs, with this work funded by the philanthropic B. Macfie Family Foundation.
For nearly two decades I have advocated the restoration of the Murray River’s estuary through removal of the 6.7 kilometres of barrage. From July 2011 through until August 2017 I maintained the ‘Myth and the Murray’ website.
On Line Opinion, Australia’s e-journal of social and political debate, published me from 2003 to 2017, with links to these articles here. I recently started writing for The Spectator, with my author page here.
