BoM/ABC team hyperventilates Heatwave health alert issued for southern Tasmania as 130yo record set to fall while ignoring Hobart Botanical Gardens 94030 had a monthly mean 22.7 in 1843 compared to 22.4 for Hobart (Ellerslie Road) 94029 Nov 2017. I wonder how many people were harmed by those warm days this month?
I see another edition in scaremongering articles about the UHI “Deadly mix of heatwaves and humidity could make some Australian cities virtually ‘uninhabitable’” cry me a river – Nobody asks “where has global warming/climate change been mostly measured these last 150 years?”

Almost a year ago I blogged – Australian Government financial disasters – time for an update next month – send in any new ideas.
I have just had a heads up from Silligy re this 2005 paper – MEASUREMENT OF AIR TEMPERATURE IN THE PRESENCE OF A LARGE RADIANT FLUX: AN ASSESSMENT OF PASSIVELY VENTILATED THERMOMETER SCREENS – pdf ~300KB – Fig 10 gives an idea of the magnitude of the differences. Commercial screen Type A naturally ventilated in the 2005 paper and Type B aspirated
I am curious what readers think is a possible way forward – and what they think will actually happen.
The resignation of Benelong MP John Alexander wipes out the slender majority enjoyed by the Turnbull Govt. So how Turnbull will navigate the last two sitting weeks of 2017 without losing a key vote has been made a bigger problem. It is interesting that it took a freelance lawyer to precipitate this crisis by pointing out obvious facts to the then Senator Ludlum. What were our top legal minds doing all these years? Closing a blind eye to the effect of Sect 44 of the Constitution?
I doubt there is any chance of a referendum passing to amend Sect 44. I note too that when it was written Canada and New Zealand were all part of the British Empire and were not thought of as foreigners – Sect 44 should have been amended decades ago.
I note too the Coalition Govt elected Sep 2013 was always a lame duck in that they could never get Liberal legislation through the Senate. They only ever passed legislation compliant with Labor/Greens/liberals.
When Turnbull just scraped back in July 2016 with a minute majority in the lower house the lame duck became lame in both legs. Now here we are and nobody will want a Christmas election.
I checked gas and electricity wholesale prices data for 2017 and the claim in the AFR Monday – South Australia’s power now cheaper than coal-fired states – Ross Garnaut –
Any notion that this is due to some triumph of wind power fails to examine the dominant driver of SA electricity which is gas. The main sources of dispatchable electricity for SA are the Adelaide gas fired power stations. Then there are the interconnectors drawing on Vic coal fired power.
The three large States which are all dominated by coal fired power are all seeing reduced wholesale prices in 2017 as the Feds and Prime Minister attack high power prices.
While checking end of October rainfall numbers at Perth water supply dams – I looked in at 2.55am on 31st Oct and I saved this table with data as at 30 Oct. Interesting that as at end October – Canning, Mundaring, Serpentine Pipehead, South Dandalup and Wungong Dams all recorded over their annual rainfall with two months still to go – and there had been 86GL of inflows for the year. Churchmans Brook and Victoria Dams were way down on their rainfall – funny that Churchmans Brook is the only one of the seven sites to record to 4 decimal places? But back to the real world.
Golly I thought – all this rain must be causing smiles at WaterCorporation as they calculate the value to WA taxpayers of all that free rain falling from the sky. I imagined articles in The West Australian mentioning all this free water.
Later at 5.51pm on 31st Oct the numbers for that day were posted – and the numbers were little changed from the 30th – see Tables below.
I checked again at 6.04pm on 1st Nov and the data for 31st was still posted but there had been a couple of changes see Tables below. Inflows jumped to 89.3 GL – maybe a cloudburst somewhere.
Looking closer I saw the numbers for Victoria Dam going haywire see tables below.
Checking on 3rd Nov the crazy numbers for Victoria Dam had moved left as per Tables below copied off the 4 screens I saved. Quick comments on numbers marked with red X. The 670.0306mm is suspect because it is the only # to 4 dec places. The 576mm is sus because it is way lower than all others. The others for Victoria Dam are sus because they record multi-metres of rainfall that never happened.
Checking today the Table has updated to 8th Nov and numbers are exactly as per 3rd Nov.
The rain chart for Victoria Dam indicates water that could meet Perth supply needs without desalination.
So nobody at WaterCorporation can be watching – it must be that nobody at WaterCorporation cares in the slightest about rainfall.
There are two temperature series for Cape Bruny on the southern tip of Tasmania. CAPE BRUNY LIGHTHOUSE 94010 and it seems that an AWS was commenced in 2002 CAPE BRUNY 94198. The BoM site map shows the screen and AWS are ~18m apart.
I downloaded the max and min monthly data from CDO online and for the years of overlap 2002 to 2016 the CAPE BRUNY 94198 annual max is 0.45° warmer on average than CAPE BRUNY LIGHTHOUSE 94010. Furthermore the AWS was warmer than Lighthouse in every year.
For the same period the CAPE BRUNY 94198 annual min is 0.16° cooler on average than CAPE BRUNY LIGHTHOUSE 94010. Furthermore the AWS was cooler than Lighthouse in 15 of the 19 years, the readings were the same for 2008 and 2012, 2013, 2014. An interesting case of BoM AWS reading on an annual mean temperature basis (how global warming is measured), consistently 0.29° C higher than Stevenson screen readings only 18 metres away. Yet the BoM maintain their AWS are calibrated to be equivalent to liquid in glass thermometers.
