Australian Bureau of Meteorology – How strong is its credibility?

A recent, large exposure to the public on our mass media outlets, firmly places “climate change” as the cause of current heat waves and “hottest year” claims, for Australia. Promoted, by the Australian BOM, it is a clear and blatant statement that the future is grim and requires immediate improvement in our drive for eliminating fossil fuel energy production and further investment in alternative solar and wind power sources.

Critical thinking regarding media information is in order to maintain a balanced viewpoint.

Refer to listing of media items below.

There is no attempt to be scientifically accurate by taking a number of other factors into account, like record cold temperatures, not just in winter but at more telling times.

Better than trying to clarify this further here, it is pertinent to introduce an article by  Jennifer Marohasy, about submissions from herself and other experts alleging the BOM’s  failure to be honest and to maintain acceptable scientific principles.

“Submissions to the Panel”

Typical entries are:

“Concerned that the Bureau of Meteorology has made many errors in its calculation of the mean Australian temperature specifically for 2013, Merrick Thomson, a retired accountant, asks a few questions in his submission including:”

“Roger Underwood was once the General Manager of the Western Australian Department of Conservation and Land Management (CALM), and for nine years was responsible for the operation of a Bureau of Meteorology (BOM) weather station.  He sent a letter to Bob Baldwin today with comment: “  I understand that you [Mr Baldwin] are overseeing the inquiry by an expert panel into the ‘homogenization’ of temperature records by the BOM.  My many scientific colleagues and I share serious concerns about the ‘homogenization’ issue.  ”

”  Ken Stewart  is a retired school principal with a deep-seated skepticism of anything produced by governments, political parties, religious organizations and big business.  Ken became interested in global warming some years ago, then decided to undertake his own audit of the then official Australian temperature record known as the ‘High Quality’ series.  This series has since been withdrawn and replaced with a new series known as ACORN-SAT.  ACORN-SAT stands for Australian Climate Observations Reference Network – Surface Air Temperature.   Ken has made a very detailed submission to the panel, which can be downloaded from his blog.  “

All of these submissions, in detail, are linked here.

Included is Jennifer’s own submission,

My submission (Jennifer Marohasy) focuses on Wilcannia, a hot and often dusty town in western New South Wales, and can be accessed by clicking here.

Further evidence of the BOM’s lack of credibility are pointed out in Jennifer’s post:


IN 2017, I published an article in the journal GeoResJ with John Abbot. This has been the subject of a misguided campaign, specifically to discredit our findings that much of the global warming through the 20th Century is natural. We recently responded to some of the criticism by way of a detailed report: ‘Historical Temperature Reconstructions and Estimating the Contribution of the Industrial Revolution to 20th Century Warming’. In due course, this will be developed into a publication.

Also, for some years I have been pointing-out that there is no consistency in the methods used by the Australian Bureau of Meteorology to measure surface temperatures, and that the routine remodeling of temperature series by the ACORN-SAT unit within the Bureau is not scientific.
