Bushfires

Bushfires, Concepts of Wilderness, and a New Book

October 9, 2020 By jennifer

Journalist Clarissa Bye from the Daily Telegraph has done a really good job of summarizing my concerns and recommendations for better bushfire management across Australia. The article entitled ‘Burning Question on Fires and Climate Link’ has been republished in so many of the News Ltd regional papers including The Frazer Coast Chronicle and The Byron Shire News and is based on Chapter 16 in my new book, ‘Climate Change: The Facts 2020’. Clarissa writes:

Dr Marohasy says insufficient hazard reduction played a part in the fuel load of the recent bushfires, and that neglecting fire management in eucalypt forests ¬simply made them “more prone to severe fires that will eventually destroy them”.

But she argues we need to return to a better understanding of traditional Aboriginal burning methods, build support for hazard reduction and develop a consistent methodology for determining fire severity.

“A focus on hazard reduction burning to keep landscapes generally more open and thus safer for people and wildlife, would be more useful than blaming climate change – at least until there is better quality assurance of actual temperature measurements,” Dr Marohasy said.

I do spend some time in chapter 16 explaining that Eucalyptus forests are not the same as rainforests and that which type of forest we end-up with will depend on how the landscape is managed – or not.

Much of Australia was open woodland at the time of European settlement and actively managed by the First Australians (Aborigines) to keep it that way. Excluding fire can help such forests transition to rainforest, but in the process the forests are more vulnerable to incineration at least until there is a proper closed-overcanopy.

So, there is actually a need for active management of the landscape to ensure fire suppression within and around these forests until a proper rainforest has established. So it is important to have firebreaks and hazard reduction burning in areas surrounding rainforests.

There is generally a very poor understanding within the dominant white Australian culture of the extent to which natural landscapes are dynamic. Indeed, the type of vegetation at any one time will depend not only on the soil type and rainfall but also on the historical fire management regime.

The Australian Aboriginal culture has a completely different, and more realistic and practical notion of land management. Indeed there is an aboriginal saying that begins: Wilderness is a land without custodians.

The article by Clarissa begins:

The bushfires that swept through Australia last summer were repeatedly des¬cribed as “unprecedented” and blamed on climate change, but a new book has rejected those claims, saying the statistics prove otherwise.

Climate Change: The Facts 2020 examines records on rainfall, hectares burnt, temperatures and the ecology of eucalypt forests, and argues that fires just as ferocious and extensive have burned in Australia since at least 1851.

In February, Paris Climate Agreement talks leader Christina Figueres described Australia’s summer bushfires as the “worst disaster that has ever hit the planet”.

But senior research fellow at the Institute of Public ¬Affairs Jennifer Marohasy, who edited the book and wrote the chapter on bushfires, says the book’s contributors assert that climate is subject to cycles, and the current situation is “not ¬unusual” or “catastrophic”.

An estimated 20 million hectares of land mass may have burned last summer.

“This is an extraordinarily vast area considering much of it was in the southeast,” Dr Marohasy said. “A similarly vast area of 21 million hectares was lost to unplanned fires as recently as 2012-13. “However, this is not the largest area burned by uncontrolled fires. In 1974-75, 117 million hectares burned.”
Only three people died in the 1974-75 fires, which burned mostly in uninhabited parts of Central Australia…

On claims Australia is drier than ever, Dr Marohasy said the wettest summer since 1990 was as recent as 2010-11.

“If anything, these official statistics suggest it is getting wetter, rainfall statistics for the entire Australian continent, available for download from the Australian Bureau of Meteorology, also indicate that more recent years have been wetter, especially the past 50 years,” she said.

Dr Marohasy acknowledges the fires were utterly devastating…
The book has chapters by biologists, atmospheric physicists, meteorologists and a volcanologist who “conclude that there is nothing unusual about the current rate or magnitude of climate change,” she said. Ends of article by Clarissa

The official statistics for the entire Australian continent do not show declining rainfall.

My new book was only available through commercial booksellers in Australia from yesterday, but in the few days preceding this we sold 600 copies through the IPA website!

The book is published by Australian Scholarly Publishers (ASP). The book is just now being shipped to the international distributor – to both their US and UK branches. Then they will be available for Amazon and BookDepository to make available for sale on their sites. This is apparently the fastest way for us to get make the books available to the international markets with cheaper shipping, but it will still take about 8-10 weeks from departure in Australia to be ready for sale on these sites.

In the meantime, the climatechangethefacts.org.au website works for domestic and also international purchases.

In his testimony to the recent Royal Commission on the devastating bushfires Andrew Johnson, the head of The Australian Bureau claimed rainfall was in decline. The data does not support this contention. When Josh Frydenberg was the Minister responsible for the Bureau he asked Andrew Johnson to meet with me. I tried to set-up several meetings, but he kept cancelling on me.
Whichever way you consider the rainfall data, including by season, there is no decline.

There are no equivalent statistics for bushfires. As I explain in chapter 16 (page 226) of the new book: “There is no consistent Australia-wide methodology for determining the severity of fires, or even the amount of forest burned by either wildfires or through prescribed burning each summer.”

After the Tragic Wildfires: History is Rewritten or Forgotten

January 13, 2020 By jennifer

The infernos of January 2020 will be remembered for destroying so much of southeastern Australia. I weep for the burns’ victims. So many people and so much wildlife in so much pain.

In terms of area of land burnt, these last few weeks may be recorded as unprecedented. This has everything to do with our mismanagement of the landscape, including the lack of hazard reduction burning especially in eucalyptus forests.

We were warned in the report from the 1939 Royal Commission by Judge Leonard Stretton, and in the more than 18 major inquiries since, forests are potentially dangerous and explosive places. Fuel loads must be kept within acceptable limits.

Blaming the recent fires on climate change is to rewrite our temperature history, something the Australian Bureau of Meteorology has been doing for some time. This has involved the:

  1. remodelling of measured values
  2. addition of hotter locations to only the most recent years in the compilation of a national average trend
  3. transition to electronic probes that are designed to record hotter for the same weather, and
  4. deleting of the hottest day in the official record, which was January 3, 1909.

These misdeeds have all been comprehensively documented, yet the current government turns a blind eye, while referring the matter of a firefighter who claims an Indigenous heritage to the Australian federal police. It is as though we are ruled over by a political elite more interested in continuing subsidies to electricity companies, and continuing funding to corrupt coral reef researchers – both of which have a vested interest in catastrophe – rather than listening to practical solutions to these and other major environment issues currently confronting Australia.

BUSHFIRE HISTORY, REMEMBERING JANUARY 1939

The “Report of the Royal Commission to inquire into the causes of and measures taken to prevent the bush fires of January 1939 and to protect life and property and the measures to be taken to prevent bush fires in Victoria and to protect life and property in the event of future bush fires” begins:

In the State of Victoria, the month of January of the year 1939 came towards the end of a long drought which had been aggravated by a severe hot, dry summer season. For more than twenty years the State of Victoria had not seen its countryside and forests in such travail. Creeks and springs ceased to run. Water storages were depleted. Provincial towns were facing the probability of cessation of water supply. In Melbourne, more than a million inhabitants were subjected to restrictions upon the use of water.

“Throughout the countryside, the farmers were carting water, if such was available, for their stock and themselves. The rich plains, denied their beneficent rains, lay bare and baking; and the forests, from the foothills to the alpine heights, were tinder. The soft carpet of the forest floor was gone; the bone-dry litter crackled underfoot; dry heat and hot dry winds worked upon a land already dry, to suck from it the last, least drop of moisture. Men who had lived their lives in the bush went their ways in the shadow of dread expectancy. But though they felt the imminence of danger they could not tell that it was to be far greater than they could imagine. They had not lived long enough. The experience of the past could not guide them to an understanding of what might, and did, happen. And so it was that, when millions of acres of the forest were invaded by bushfires which were almost State-wide, there happened, because of great loss of life and property, the most disastrous forest calamity the State of Victoria has known.

“These fires were lit by the hand of man

“Seventy-one lives were lost. Sixty-nine mills were burned. Millions of acres of fine forest, of almost incalculable value, were destroyed or badly damaged. Townships were obliterated in a few minutes Mills, houses, bridges, tramways, machinery, were burned to the ground; men, cattle, horses, sheep, were devoured by the fires or asphyxiated by the scorching debilitated air. Generally, the numerous fires which during December, in many parts of Victoria, had been burning separately, as they do in any summer, either ‘under control’ as it is falsely and dangerously called, or entirely untended, reached the climax of their intensity and joined forces in a devastating confluence of flame on Friday, the 13th of January.

“On that day it appeared that the whole State was alight. At midday, in many places, it was dark as night. Men carrying hurricane lamps, worked to make safe their families and belongings. Travellers on the highways were trapped by fires or blazing fallen trees, and perished. Throughout the land there was daytime darkness.”

THE IMPORTANCE OF HAZARD REDUCTION BURNING

Just last week, at the height of the January 2020 bushfire emergency, Minister for Home Affairs Peter Dutton referred a complaint against a firefighter, who allegedly falsely claims Aboriginal heritage, to the Australian federal police. I have no opinion on Bruce Pascoe’s lineage, but I do know that the Mob he identifies with have real solutions to our recurrent bushfire tragedies. Their culture has a long history of land management through the expert use of fire as a tool to create visually pleasing and practical mosaics resistant to the spread of wildfires.

Bruce Pascoe’s book Dark Emu draws from the more technical work by Bill Gammage entitled “The Biggest Estate on Earth”. This tome explains how Aborigines actively and skilfully managed the land in a far more systematic way than has ever been acknowledged. And I know, from my time spent reading original sources at the South Australian Museum about the Yaraldi of the Lower Murray River, that there were also complicated systems of governance, with a focus on a sustainable harvest and the storage of food.

Judge Stretton’s 1939 report also noted:

When the early settlers came to what is now this state [of Victoria], they found for the greater part a clean forest.Apparently, for many years before their arrival, the forest had not been scourged by fire … Their canopies had prevented the growth of scrub and bracken to any wide extent. They were open and traversable by men, beasts and wagons. Compared to their present condition, they were safe” (p. 11).

While quick to refer Bruce Pascoe, who is best known for his unorthodox perspective on Aboriginal history, to the federal police, Minister Dutton and his government have over a very long period of time turned a blind eye to the rewriting of Australia’s historical temperature record by Blair Trewin and David Jones of the Australian Bureau of Meteorology. The work of Trewin and Jones underpins the notion of an unprecedented climate emergency, when the real issues are perhaps management of fuel loads in forests and current resourcing.

Indeed, now absurdly corralled by the climate change meme, Prime Minister Scott Morrison is actively promoting the need for yet another Royal Commission as though this will prevent future bush fire tragedies. Yet recommendations of previous Royal Commissions have never been implemented. For example, a hazard reduction burn across at least 390,000 hectares each year was recommended for the state of Victoria.

It is because “The Elites” don’t trust the work of practical land managers, whether that be thinning young forests to ensure that a proper over-storey canopy develops, or adopting straight-forward hazard reduction burningprogrammes. Climate change may be a convenient scapegoat, but it will not protect our land into the future.

HOTTER AND DRIER SUMMERS

Sunday morning on national television the Prime Minister said a Royal Commission into “the killer bushfire season” is necessary and reiterated claims that the nation is facing a “new normal”, with more severe natural disasters on the way; he said he would be seeking more powers to allow the Australian Defence Force to respond more quickly.

Bill Gates has famously said that if you can’t measure it you can’t manage it, and that fundamental to improvement is the capacity to accurately measure.

Yet we have a situation where key statistics are either remodelled or ignored.

Mr Morrison mentioned hotter and drier summers in his television address. The historical record shows that the land mass of Australia is not drying out. Last year, 2019, was exceptionally dry. But the long-term trend is not towards a drier continent but rather we have on average had consistently wetter years since the 1970, as shown in Figure 1.

Figure 1. Annual average rainfall for Australia, 1900 to 2019.

It is also the case that summers are not getting drier, as shown in Figure 2.

Figure 2. Average summer rainfall since 1900.

According to the Bureau, recent summers have been hotter, but such claims would not pass scrutiny if assessed, for example, for inclusion in the Guinness Book of records. This is because of all the changes to the way temperatures are now measured.

The Rutherglen agricultural research station has one of the longest, continuous, temperature records for anywhere in rural Victoria. Minimum and maximum temperatures were first recorded at Rutherglen using standard and calibrated equipment back in November 1912. Considering the first 85 years of summer temperatures – unadjusted, as in not homogenised – the hottest summer on record at Rutherglen is the summer of 1938–1939.

Figure 3. The hottest summer at Rutherglen was the summer of 1938-1939. This chart only extends to the summer of 1997-1998. Since January 1998 temperatures have been measured with a electronic probe and it is impossible to know whether it is measuring hotter or colder than the original mercury thermometer, because the Bureau makes none of this information public.

At Rutherglen, the first big equipment change happened on 29 January 1998. That is when the mercury and alcohol thermometers were replaced with an electronic probe – custom built to the Australian Bureau of Meteorology’s own standard, with the specifications still yet to be made public.

According to Bureau policy, when such a major equipment change occurs there should be at least three years (preferably five) of overlapping/parallel temperature recordings. Except the mercury and alcohol thermometers (used to measure maximum and minimum temperatures, respectively) were removed on exactly the same day the custom-built probe was placed into the Stevenson screen at Rutherglen, in direct contravention of this policy.

The policy implications are significant, far more significant than Bruce Pascoe paraphrasing some text from the early explorers to make a point, while claiming an Aboriginal heritage.

In 2011, the Bureau made further changes to how it measures temperatures in that it stopped averaging one-second readings from the probe at Rutherglen over one minute. The maximum temperature as recorded each day at Rutherglen is now the highest one-second spot reading from the custom-built probe. That is correct – spot reading.

Across Australia non-standard methods of measuring (spot readings) from non-standard equipment (custom-built probes) make it impossible to establish the equivalence of recent temperatures from Rutherglen – or any of the Bureau’s other 695 probes in automatic weather stations – with historical data.

REWRITING OUR TEMPERATURE HISTORY

It was at the Sydney Institute in 2014 that I first began to detail the extent to which the Australian Bureau of Meteorology has rewritten our temperature history to create the impression of catastrophic global warming using the technique of homogenisation. This is in addition to the issues with calibration.

Back in 2014, I showed how temperatures are changed in the ACORN database, and not by a small amount. I showed that the recorded values — the actual measurements — are often changed by more than a degree from the original measurements to remove the cooling trend from at least 1940 to 1960. Cooling the past, makes the present appear hotter.

If we consider, as an example, Bourke in western New South Wales, the temperature as measured using a mercury thermometer in a Stevenson Screen at the official recording station was 38.9 degrees Celsius.  This value was changed to 38.4 in the first official ACORN database, and then dropped-down by a further 0.3 degrees when the Bureau published version 2 of ACORN.

Table 1. Temperatures actually recorded at Bourke in January 1939, and temperatures then changed for the first version of ACORN, and then changed again for the next version of ACORN.

This is in addition to the more recent issues that I have uncovered, issues caused by the transition to electronic probes without due regard to calibration. In the case of Mildura, I have shown that the official electronic probe is regularly recording 0.4 °C hotter than the mercury thermometer in the same shelter.

Then there is the issue of how all the temperature series are added together.

Concerned that the Bureau made many errors in its calculation of the mean Australian temperature, Merrick Thomson, a retired accountant, asked questions in a submission to a government inquiry some years ago, specifically:

  1. Why was the mix of stations changed with the transition to ACORN, and why was this not explained and declared, particularly given that it has resulted in a large increase in theannualtemperature for Australia.Hecalculates this was 56 °C.
  2. What criteria is used to determine whether or not a station becomes part of the national network, and specifically, why was the very hot location of Oodnadatta added to the national network in 2011?

His submission was never acknowledged, and his questions never answered.

So, when the Bureau announce that last year was the hottest on record we can have absolutely no confidence that this is true.  The charts they show, and values they present are totally contrived.

I recently explained to Chris Smith on Sky News that the hottest day ever recorded in Australia using standard equipment at an official recording station is 51.6 °C at Bourke in January 1909. I also explained that this legitimate record has been expunged from the record by Blair Trewin at the Bureau.

Over the last six years I have provided more and more evidence — some of it reported by Graham Lloyd and published in The Australian — which shows Blair Trewin, under the direction of David Jones, is falsely rewriting our temperature history.But nothing has ever been done about this. Rather, successive state and federal governments have let the meme of human-caused catastrophic global warming grow, while neglecting the forests.

I have it on good advice that the detail of my accusations against the Bureau have been discussed by the Australian Cabinet, including in the presence of Peter Dutton and Scott Morrison. At that time then prime minister Tony Abbott was apparently keen to have some sort of inquiry into the industrial-scale remodelling by Jones and Trewin through the process of homogenisation. But his efforts were thwarted by Greg Hunt and Julie Bishop.

REWRITING THE HISTORY OF THE LOWER MURRAY RIVER

When it comes to really important practical environmental issues like restoring the Murray River’s estuary, they also all turn a blind eye.

The Tauwitchere sea dyke has destroyed the once abundant fishing grounds of the Yaraldi. This Mob once caught both Murray cod and also mulloway depending on the season; it is all detailed in the South Australian Museum. The solution to the dwindling fish stocks in the Lower Murray River is simple: remove the barrages and bring back the sea tide. Instead some locals complain of climate change.

Since 1941, the barrages have blocked 90 per cent of flows between the lakes and the South Ocean. Over the last decade, a new and false history and geography of the Lower Lakes, Coorong and the Murray’s mouth have been created. But so far, no government minister has ever rallied against this rewriting of history.

When I wrote a report about it, explaining all the benefits that could come from restoring the Murray River’s estuary, the Australian Broadcasting Corporation (our ABC), ran a campaign against me.

The restoration of the Murray River’s estuary would not only be good for the environment, but it would also free-up so much water for upstream farmers and firefighters.

ELITES RUN AUSTRALIA, BUT FOR HOW MUCH LONGER

For decades respected Aboriginal elders have been invited onto local bushfire management committees, only to find government-appointed chairpersons refusing to even record their advice. In the Dreaming active land management is so important, while a particular zeitgeist and red tape now most deliberately prevent it. Then there is the issue of adequate resourcing. So, much money is provided to science managers to fake news about the Murray River, the Great Barrier Reef and human-caused catastrophic climate change. Yet the real and pressing issues concerning management of weeds, feral animals, and fuel loads in forests is mostly ignored. Meanwhile, artificial constraints on commercial opportunities for the sustainable harvest of so much of our natural bounty, including kangaroos and crocodiles, are indirectly imposed by Hugh Jackman and other Hollywood celebrities who support campaigns led by Terri Irwin. Grahame Webb has spent a lifetime overseeing the successful resurgence of crocodile numbers in the Northern Territory, only to now be prevented from realising any commercial gain for his Aboriginal colleagues because of successful campaigning by Hollywood Elites.

As Bruce Pascoe writes in Black Emu:

Strangely, though, when Ross Garnaut, who prepared the climate-change policy for the Rudd Government in 2008, championed kangaroo farming as a way of conserving the land and cutting greenhouse gases, because cattle are greater polluters than motor cars, the press could hardly contain their contempt” (p. 53).

I’ve discussed the need to not only restore the historical temperature record, but also the need to restore the estuary of our longest river system, with Minister Simon Birmingham. But he tells me that there is no advantage in it for South Australia. Also, he has told me that the Australian Greens — effectively run by his mate and fellow South Australian Sarah Hanson-Young — would never support such an initiative.

I met with Sarah Hanson-Young back in 2011. She told me that while she sees some merit in the Murray River having an estuary, South Australian Greens and Liberals ‘will hold the line’ together on this one.

It is the case that here in Australia, just a few rule over us, and at the behest of their politics that has scant regard for the natural environment, and little more for the economy.

Contrary to the impression given by our ABC, quiet Australians of diverse lineage are not being heard, while the mostly white leadership across The Greens, Coalition and Labor parties together decide how key issues will be managed.

Worse, it is a fact that practical individuals who operate outside the current zeitgeist are hounded by our elites and our government.

Peter Ridd was sacked for telling the truth about the Great Barrier Reef under the watch of the current Coalition government. If Peter Dutton wants to be useful, he would refer Terry Hughes rather than Bruce Pascoe to the Australian federal police. Perhaps Minister Dutton has not yet heard about the latest revelation of misconduct from within the ARC Centre of Excellence for Coral Reef Studies at James Cook University?

The political Elite know there is a disproportionate influence from what is understood as the AGL* faction of the New South Wales Liberal party. It is this faction that not only ensures various subsidies for various energy sources, but also oversaw the taxpayer funded $443 million grant to the tiny Great Barrier Reef Foundation — to Malcom Turnbull’s mates. I heard not a slither of discontent from Minister Dutton on this, yet the faux research findings they sponsor directly and negatively impact all Australians.

There is a real need for Peter Dutton to make important referrals to the Australian federal police. Those who do fake science and attempt to pass it off as the truth, and those who remodel the historical temperature record to something completely different, need to be held to account.

The terrifying infernos of recent weeks are a wake-up call. It is time that the Prime Minister and all the Ministers in the current Australian Government showed some real leadership. They know the real issues, and they understand the politics. So, it is past time they climbed out from under the thumbs of the catastrophists embedded in our most important government-funded institutions. Stop taking orders from them, and start referring them to the Australian federal police.  Their misdeeds are significant.

UPDATE JANUARY 16, 2020

Adding an east coast of Australia rainfall chart, as requested by a couple in the thread. Whichever way you cut the data, Australian rainfall data does not show a drying trend, and for non-UHI affected inland sites the temperatures generally show cooling to about 1960, and then warming since. Its about as warm now as it was back more than 100 years ago. This is no consistent with lots of homogenised data from other places … but I think many sceptics and alarmists should spend more time with the data before forming their opinion.

Annual average rainfall for the east coast of Australia.

It has been hotter, fires have burnt larger areas

January 4, 2020 By jennifer

The word unprecedented is applied to almost every bad thing that happens at the moment, as though particular events could not have been predicted, and have never happened before at such a scale or intensity. This is creating so much Klonopin anxiety, because it follows logically that we are living in uncertain time: that there really is a climate emergency.

The historical evidence, however, indicates fires have burnt very large areas before, and it has been hotter.

Some of the catastrophe has been compounded by our refusal to prepare appropriately, as is the case with the current bushfire emergency here in Australia. Expert Dr Christine Finlay explains the importance of properly managing the ever increasing fire loads in an article in today’s The Australian. While there is an increase in the area of national park with Eucalyptus forests, there has been a reduction in the area of hazard reduction burning.

The situation is perhaps also made worse by fiddling with the historical temperature record. This will affect the capacity of those modelling bushfire behaviour to obtain an accurate forecast.

We have had an horrific start to the bushfire season, and much is being said about the more than 17 lives lost already, and that smoke has blown as far as New Zealand. Unprecedented, has been the claim. But just 10 years ago, on 9 February 2009, 173 lives were lost in the Black Saturday inferno. On 13th January 1939 (Black Friday), 2 million hectares burnt with ash reportedly falling on New Zealand. That was probably the worst bushfire catastrophe in Australia’s modern recorded history in terms of area burnt and it was 80 years ago: January 13, 1939.

According to the Report of the Royal Commission that followed, it was avoidable.

In terms of total area burnt: figures of over 5 million hectares are often quoted for 1851. The areas now burnt in New South Wales and Victoria are approaching this.

Last summer, and this summer, has been hot in Australia. But the summer of 1938-1939 was probably hotter. In rural Victoria, the summer of 1938-1939 was on average at least two degrees hotter than anything measured with equivalent equipment since, as shown in Figure 1.

Figure 1. Mean maximum summer (December, January February) temperatures as measured at Rutherglen in rural Victoria by The Australian Bureau of Meteorology for the period when mercury thermometers were used. Data unadjusted/not homogenised.

The summer of 1938-1939 was probably the hottest ever in recorded history for the states of New South Wales and Victoria. It is difficult to know for sure because the Bureau has since changed how temperatures are measured at many locations and has not provided any indication of how current electronic probes are recording relative to the earlier mercury thermometers.

Further, since 2011, the Bureau is not averaging measurements from these probes so the hottest recorded daily temperature is now a one-second spot reading from an electronic devise with a sheath of unknown thickness. In the United States similar equipment is used and the readings are averaged over five (5) minutes and then the measurement recorded.

The year before last, I worked with the Indonesian Bureau of Meteorology (BMKG), and understood their difficulty of getting a temperature equivalence between mercury thermometers and readings from electronic probes at their thousands of weather stations. The Indonesian Bureau has a policy of keeping both recording devices in the same shelter, and taking measurements from both. They take this issue very seriously, and acknowledge the problem.

The Australian Bureau of Meteorology has a policy of a three year period of overlap, yet the metadata shows that for its supposedly highest quality recording stations (for example Rutherglen), the mercury thermometer is removed the very same day an electronic probe is installed. This is a total contravention of the Bureau’s own policy, and nothing is being done about it.

I explained much of this to Australia’s Chief Scientist in a letter some years ago — neither he, nor the Bureau, deny that our current method of recording temperatures here in Australia is not covered by any international ISO standard. It is very different from methods currently employed in the United States and also Indonesia, and as recommended by the World Meteorological Organisation.

Then there is the issue of the remodelling of temperatures, I explained how this affects trends at Rutherglen in a blog post early last year.

The remodelling, that has the technical term of homogenisation, is a two-step process. With respect to the temperature maxima at Rutherglen, the Bureau identified a ‘statistically significant discontinuity’ in 1938–1939. Values were then changed.

It is somewhat peculiar that the Bureau did not recognise, in its process of remodelling the historical data for Rutherglen, that the summer of 1938-1939 was exceptionally hot because of drought, compounded by bushfires. Rather David Jones and Blair Trewin at the Bureau used the exceptional hot January of 1939 as an excuse for remodelling the historical temperature record at Rutherglen, with the changed values subsequently incorporated into international data sets.

These made-up values are then promoted by the United Nations’ International Panel on Climate Change (IPCC). This propaganda is then tweeted by Hollywood superstars like Bette Midler to The Australian Prime Minister.

After a recent Sky News Television interview that I did with Chris Smith several people have contacted me about the hottest day ever recorded in Australia. They have suggested it is 16th January 1889 being 53.1 degrees Celsius at Cloncurry in Queensland. A problem with this claim is that the temperature was not measured from within a Stevenson screen, though it was a recording at an official station. A Stevenson screen (to shelterer the mercury thermometer) was not installed by Queensland meteorologist Clement Ragge at Cloncurry until the next month, until February 1889.

The hottest temperature ever recorded in Australia using standard equipment (a mercury thermometer in a Stevenson screen) at an official recording station is 51.7 degrees Celsius (125 degrees Fahrenheit) at the Bourke Post Office on January 3, 1909.

We are all entitled to our own opinion, not not our own facts.

No QA of bureau temperature data by CSIRO bushfire modellers

October 27, 2016 By jennifer

Despite an exceptionally cool end to this October, the CSIRO and Bureau of Meteorology have just put out a joint report claiming that there is going to be an increase in the number of hot days and thus an increased risk of devastating bushfires — based on homogenised (remodelled) temperatures, of course.

CSIRO experts forecast bushfire risk based on Bureau temperature data, but they don’t first undertake any quality assurance of the Bureau’s data.

If we consider one of the best long and continuous temperature series for southern Australia, which is the Rutherglen raw temperature data, and just maximum temperatures in summer: the hottest summer was back in 1938-1939, as shown in this chart.

Mean Maximum temperatures as measured at Rutherglen during summer (December 1912 to February 2016). Full report at http://climatelab.com.au/newclimate/10.22221/nc.2016.001/
Mean Maximum temperatures as measured at Rutherglen during summer (December 1912 to February 2016). More more information see http://dx.doi.org/10.22221/nc.2016.001.

On 13 January 1939 this region experienced one of the worst bushfire disasters in Australia’s history; it became known as Black Friday.

At 33.5°C, the summer of 1938–39 was 2.2°C hotter than the average maximum temperature during the ten most recent summers at Rutherglen, and a full 3°C hotter than the average maximum summer temperature at Rutherglen for the entire period of the record.

And yet today the Bureau and CSIRO are suggesting we should be concerned by a 1°C increase in average temperature over the last 100 years.

Rather than fear mongering, the CSIRO would do well to actually consider the actual integrity of the data being provided by its partner – the Bureau of Meteorology.

In a recent article published by On Line Opinion, I explained that the difference between the official-adjusted maximum temperature for Rutherglen on 13th January 1939 versus the actual measured value is rather large– more than 5 °C. Historical temperature data is used to model and forecast the likely impact of future bushfires, with Fire Danger Indices sensitive to small changes in temperature.

Philosophising on Bushfires: A Note from David Ward

July 16, 2014 By jennifer

FIRE in the landscape, or bushfire, is Australia’s most lethal and costly natural hazard. Big, uncontrollable bushfires can kill millions of trees and wild animals, thousands of farm animals, and sometimes humans too. Apart from deaths, bushfires incinerate property, such as bridges, farm fencing, homes, and even, a few years ago, an astronomical observatory. The cost to the economy is significant. So bushfire management is, for Australians, no trivial matter. Yet, despite many enquiries since the 1930s, we still have serious bushfires, which seem to be increasing in extent and intensity.

Philosophers may be interested in bushfire epistemology, logic, ethics, aesthetics, and ontology. Bushfire epistemology is very diverse, including traditional Aboriginal knowledge; historical records from early European settler diaries, letters, and journals; recent scientific research; economics, politics; law, and even psychology. Logic is needed to pull these together and arrive at rational policy on bushfire.

Although logic may seem to point to a particular solution, we must beware of the paths of false logic. Also, there may be ethical objections to some seemingly logical solutions. For example bulldozing all native vegetation might abolish bushfire, but would not be a good idea from many other points of view. Even aesthetics come into the picture. Many urban Australians, of recent migrant descent, see blackened ground as ugly, but Aborigines see it as beautiful, and describe it as ‘cleaned up’. Although bushfire is no doubt ugly to victims, flames do have a certain beauty, especially when mild and not threatening. Many of us like a campfire. Ontology is always useful, to distinguish between what is real, and what is imaginary.

While local volunteers provide most of the weary fire fighters, they are under the ultimate direction of salaried fire officers, who are public servants, wear white shirts, big hats, many medals, and appear on television, looking worried. Budget and big hats may be central to their thinking. Policy and budget are largely dictated by leading politicians, who may have budgets and metaphorical big hats of their own, and usually appear by helicopter in the aftermath, dispensing sympathy.

It may seem, to some, that Australia has addressed the bushfire bureau-political chain well (especially the hats, medals, helicopters and sympathy), yet there is ongoing dispute over the best way to actually prevent destructive bushfires. Some, including most farmers and volunteer bushfire fighters, with practical bushfire experience, are in favour of simplification, by returning to something like traditional Aboriginal management, where the bush was deliberately lit at short intervals, in a mosaic pattern, so keeping fuels low, and fires mild, even in summer. Local knowledge is essential for this approach. Those in white shirts should play a supporting, not directing role. In other words, let’s make fire our friend, and use fire to fight fire.

There are many historical accounts of this approach, for example the early German explorer Ludwig Leichardt described frequent mild bushfires in New South Wales in the 1840s, lit by Aborigines. He pointed out that such fires, although widespread and common, were not a threat to humans. I suspect there were few big hats and medals in those days. Early European farmers imitated Aboriginal burning, to keep themselves safe. More recent bushfires in New South Wales, often in long unburnt areas such as National Parks, have been unmistakeably menacing, due to heavier fuel. In 2013 bushfires in NSW caused two deaths, and the loss of 248 houses. The cost was put at $94 million.

Some natural scientists say that bushfire history is anecdote; or mythology; that little is known about Aboriginal burning; or even that such burning is impossible; and that frequent, mild fires destroy ‘biodiversity’ (however that slippery word may be defined). They say that history is unreliable, and only natural science can lead to the truth about bushfire. I suspect that the philosopher Robin G. Collingwood might have strongly disagreed with that view, since he saw history as an essential part of human understanding. Scientists should be aware that there is a history of science.

However, one Australian professor of biology, apparently dismissing history, wrote a letter to the prestigious journal Nature, titled “Don’t Fight Fire with Fire”. This may have reinforced his appointment as a bushfire adviser to the New South Wales government, from 1996-2004. In that time there were many uncontrollable bushfires. We should not, of course, allow ourselves to be misled by the old logical error of post hoc, ergo propter hoc, but we can still ponder. That professor now holds an academic appointment in the United Arab Emirates, where I would imagine there are few bushfires. Again, we should avoid assuming that his presence there has brought about that situation.

But is biology the most reliable source of information on bushfire? Biologists usually use statistical induction, which is a useful tool, but can be misused. Logical blunders have been noticed in refereed natural science journals. Could the broader scope of philosophy help us to get closer to the truth? History, and practical experience, can be astringent cross checks on findings by the scientific method, or a version thereof.

The cynic Ambrose Bierce is not widely acclaimed as a philosopher, yet he did have some useful insights. Before the First World War, in his ‘Devil’s Dictionary’, the cunning old codger defined logic as “The art of thinking and reasoning in strict accordance with the limitations and incapacities of the human misunderstanding”. This may dismay learned, studious people like me, who are entranced by our own beamish logic, but we should remember that Ambrose also defined learning as “The kind of ignorance distinguishing the studious”.

The perspicacious Ambrose did not stop there. He gave a clear example of a suspect syllogism, in which the statement that sixty men can do a piece of work sixty times as quickly as one man (major premise), followed by the statement that one man can dig a post-hole in sixty seconds (minor premise), leads to the unavoidable mathematical conclusion that sixty men can dig a post-hole in one second. Those who have, at one time or another, actually had a shovel in their hands, may find this questionable.

Similarly, those who have, at one time or another, actually had a fire hose in their hands, breathed smoke up their nostrils, felt the enormous radiant heat of fire in long unburnt fuel, heard the roar, and felt the ground shake as a bushfire goes its merry way, may be perturbed at statements by some studious ecologists, apparently supported by statistical evidence, that deliberate, mild burning in cooler weather, to mitigate uncontrollable holocaust bushfires in hot, windy weather, is ineffectual, and harmful to the bush.

Apart from ecology, lawyers have their own philosophy, called jurisprudence. Like Ambrose Bierce, some medieval Scottish lawyers may not be recognised as philosophers, but showed perspicacity in taking the Latin verb reptare (to crawl or creep) and forming the legal terms subreption and obreption. These mean, respectively, to crawl under the truth, and to crawl over it; in other words to mislead by telling less than the whole truth, or by telling more than the whole truth. In bushfire debate, as in courtrooms, we need the truth, the whole truth, and nothing but the truth.

The post-hole syllogism is a clear example of subreption, as are some claims made in the bushfire debate. Some news media reports, or papers in refereed journals of ecology, may mislead public, and hence political opinion. As an example, it may be said that vegetation has been destroyed, without a close definition of that word. Although they may appear to be dead, many Australian plants are well adapted to bushfire, have lignotubers, and resprout readily soon after it. They are no more destroyed, by mild fire, than a garden shrub which is pruned. Other Australian plants need fire, or smoke, in order to flower, or germinate from seed. Words can be deceptive, as philosophers such as Locke, Hobbes and Wittgenstein noted.

With regard to the political aspects of bushfire, Ambrose Bierce had it well covered. He defined politics as a strife of interests masquerading as a contest of principles. The strife of interests includes winning the votes of urban dwellers who are rarely subject to bushfire, yet may have assorted passionate notions about its ecology, perhaps gleaned from refereed journals. The contest of principles, in this case, is the ethical duty of care to both nature and human society.

As a former loyal public servant, I won’t give Ambrose’s cynical definition of the word politician, but it involves the word eel. We should remember, of course, that dictionaries can be wrong. Let’s hope that philosophy can come to the rescue, and that there are at least some worthy Australian politicians, and public servants, who understand that bushfire is Australia’s most lethal, costly, and urgent natural hazard, and won’t use pseudo-science to wriggle out of their duty of care, or ignore bushfire in the hope that it will go away, or become somebody else’s responsibility. Should a basic grasp of philosophy be a requirement for political office? Plato thought so.

Might governments have a Department of Philosophy, to peer deeply into the claims of tendentious lobbyists, no matter what their academic qualifications in natural science, or the length of their publication lists? There is an opinion that those who publish the most, often have the least to say. It’s a pity that Ambrose Bierce disappeared in 1914, so isn’t here to join the debate on philosophy and bushfire. I hope some from Australia, or other fire prone lands, such as USA, Canada, Africa, and even Europe, will.

Vale Ray Evans & How to Win an Argument

June 19, 2014 By jennifer

I first meet Ray Evans at a dinner at the Institute of Public Affairs. It must have been in about 2004, ten years ago, because I had just seen the movie ‘The Day After Tomorrow’. Staring Dennis Quaid as a paleoclimatologist professor, the movie was about the Gulf Stream shutting down resulting in catastrophic global cooling and a new ice age.

Ray Evans 1935-2014
Ray Evans 1935-2014

We were seated at the same table and I mentioned that I had enjoyed the movie, that it had been entertaining. He was scathing of my comment, while admitting he hadn’t seen the movie, and didn’t intend to. He understood that it was themed around advocacy for anthropogenic global warming. Ray was already vehemently opposed to the new doctrine. While he wasn’t keen to discuss the plot of the movie, he was keen to engage me in a discussion of the Gulf Stream.

I think that the next time we meet was at a lunch in Perth, also hosted by the IPA. On that occasion he was scathing of my suggestion that wind turbines could be beautiful. I may have also attempted a defence of wind farms as a source of renewable energy. But was properly put in my place by Ray who had a great depth of knowledge, not only of the economics of wind farming, but also of the quantities of steel and cement used in the construction of each turbine and their associated carbon footprint.

Whenever we met, he always managed to challenge my opinion and impart new knowledge and win the argument.

I now know a lot more about renewable energy, especially after reading an article by Ray full of useful facts and distressing politics published by Quadrant in July 2012 entitled ‘The Ruinous Privileges of Renewable Energy’.

Ray also knew a great deal about bushfires and the politics of control burning in Victoria. When it came to many issues, Ray Evans seemed able to see the wood and the trees and how big the forest was, but he never seemed daunted. Not in the least, and he always seemed to revel in the small facts.

You win arguments by understanding the detail. By forcing your opponent to engage with you on the detail. He once said something like that to me.

Ray stood for enlightenment values from a conservative Christian perspective and seemed to have a deep understanding and knowledge of everything that threatened that ethic.

And he believed you won arguments by getting into the detail. That is perhaps the most useful piece of information that he imparted to me, and by example.

Thank you Ray.
