ABC jumps shark in Roper River fairystory

We are all used to the ABC beating up climate, environmental and indigenous issues. Here we have a resources company as the classic bad guys who are applying to use 3,300ML (3.3GL) of Roper River water per year to process heavy minerals. The ABC headline “Roper River will ‘disappear’, traditional owners say, as government considers massive water allocation” – academic experts are quoted. Words such as ‘disappear’ and ‘massive water allocation’ would have many ABC readers enraged that such perfidy and disregard for the environment indigenous people could happen. However a quick check of Wikipedia reveals the Roper mean annual outflow to be 5,000GL – so the mine wants 0.06%!!! The quota would be lost in the noise of the maths uncertainties. I am sure the Gov could devise a scheme for the miner to dam some water in the wet – would never be noticed – then provide export income, wages, royalties, taxes, fund universities, indigenous employment, improved outcomes all around.

Giles in central Australia is not a pristine weather station site

The BomWatch blog has published Day/Night temperature spread fails to confirm IPCC prediction examining max min and DTR temperature data from the BoM purpose built weather station Giles 13017 in far eastern WA near the WA-SA-NT border junction. The main points of the BomWatch article is that Giles is a pristine site and that DTR has not closed as the IPCC expects. In 2014 I blogged on the loony-toon BoM adjustments to Giles for ACORN 1. So I have a 2013 Giles Basic Climatological Station Metadata pdf – a sort of station diary – on my HDD. A check of the Giles pdf shows that a gravel road that ran through the instruments area near the screen was bitumen sealed in the 12 months between the Sep 2011 and Sep 2012 site maps. Ken Stewart blogged on the Giles site in 2019 The Wacky World of Weather Stations: No. 171- Giles (WA) and Ken shows Google Earth images that indicate the screen was ~20m from the sealed road. So the sealed road would introduce some quota of UHI into the data. Ken also pointed out that a 2019 site photo from JoNova shows the whole area of the screen fenced rectangle covered by gravel with no grass – Ken rates the site “non-compliant”. The 2013 Giles Basic Climatological Station Metadata pdf shows on page 23 Station Equipment History that on 1st June 1992 under Air Temperature that – “INSTALL Temperature Probe – Dry Bulb (Type Rosemount)”.
So prior to 1st June 1992 temperatures would have been recorded by liquid in glass thermometers probably in older/larger type Stevenson screen. The post 1992 probe would produce readings over very short periods of seconds which would lead to higher temperatures being recorded than would have been recorded by a liquid in glass thermometer.

Outback SA wet not so unprecedented as BoM claims

We have all seen the news over the weekend of flash flooding on the Eyre Peninsula and other areas of South Australia – this ABC article quotes the BoM saying “We’ve seen seven all-time records up until this point through the Eyre Peninsula largely,” Mr Lainio said. “Falls of anywhere between, say, 80 to 90 millimetres to over 150mm in a 24-hour period. Those locations have never seen falls of that amount.” I did a quick search for monthly rainfalls and found that an event in Feb 1946 seems in a similar ballpark to the big falls last weekend.
Moonaree 16029 ~150km N of Kimba had over 200mm rain in Feb 1946 and 2 days around 18th registered 197mm. So here we have another instance of where the BoM aided & abetted by the ABC fail to find rain from BoM history. Map made at BoM “Recent and historical rainfall maps” – choose your time.

Maps & charts raise question the CCP released Omicron

Readers here might recall that in April 2020 I blogged “WuhanVirus as a ChiCom ops”.
On 26Jan2020 I had blogged “Australia Day & coronavirus thoughts” as it looked obvious to me people were flooding our border at airports with no health checks. Anyway – fast forward to 2Jan2022 as we cope with the huge Omicron case numbers surge and I thought “I wonder how China is coping with Omicron?”. This JHU map shows that Omicron is an absolute “nothing-burger” in China despite flooding almost every corner of planet Earth with a huge Christmas surge in Covid case numbers. So is the CCP so confident they are untouchable that they could have developed Omicron in a lab and planted it around the world? Johns Hopkins University & Medicine Coronavirus global map
Larger map. I should have added that a week ago David Archibald has said that Omicron came from a laboratory.

Perth Airport max T history 1945-2021

An email from Perth pointed out the plentiful mild weather lately. I see that Perth Airport 9021 is used in ACORN so I have had a look-see at all the raw monthly max data from CDO – (December data up to 16th so far). Perth Airport monthly max T anomalies The first thing that hits me is a step-change coincident with the June 1994 install of a temperature probe (AWS). For larger version chart. Yet the BoM ACORN version for 9021 has no adjustment at 1994. The other point I would make is that UHI would have been steadily affecting this site as Perth housing & suburbia expanded producing warmer breezes. I can look at ACORN data later.
Here is a chart of raw monthly min data from CDO. Less noisy than the max.
For larger version chart.
Here is a chart of annual mean T plus annual Range (mean T is the metric for “IPCC Global Warming/Climate Change”) For larger version chart.
