Opinion: Science of Climate Change

I was recently sent an email (at bottom of article) detailing how the year 1896 was hot and how this throws doubt on climate change. I decided to take some time to respond

Ok I will take this on and I am going to spend my 25 minute morning tea looking at the research listed in the article, rather than hyperlinking in my response I have added reference tags and listed them at the bottom of the email.

The article below also reference a lot of stories from old newspapers, about half of which are a bit pointless and are more for dramatic effect than for actual information, but hey maybe they needed to gussy it up a bit. One of the issues I have with the whole debate is that on both sides there are a lot of people claiming to be experts but have no qualifications at all, this article is a case in point, it can be source back to three authors, the first has no qualifications and the second having science qualification but in a not totally relevant field. To my mind this is the same as me having a serious heart condition and going to see a) A guy on the internet who has read about heart issues or b) a proctologist.

Firstly some attribution and biography

Big chunks of the article are drawn from here – http://mclean.ch/climate/Submissions/JMcL_Subm_AUS_Senate_extreme_events.pdf

Which was then edited and backlinked into oblivion before being posted here – http://joannenova.com.au/tag/pidgeon-lance/ or vice versa, bit of a chicken and egg thing but it is now being reposted and emailed all over the shop.

John McLean

Computer consultant and occasional travel photographer(from his own webpage)

Mr McLean calls himself a “climate change data analyst” because he can apparently use an excel spread sheet, he also show the sort of arrogance that is pretty rife in the IT industry in saying that the inability to track data through an excel spread sheet somehow negates any other qualifications you may have[1]. He has no training nor expertise in either climate change nor indeed nor science in general but the man can whip up a nice spread sheet and use statistics to his advantage, he is also part of two ‘scientific’ organisations that get their funding from big oil [2][3][4].

His claim to 3 peer reviewed articles is also a bit interpretive and his accuracy has been disputed multiple times [2][5][6][7] [8].

Joanne Nova

An actual scientist, a molecular biologist to be precise but a scientist none the less. Also very successful children’s author and television presenter but then again so is Bill Nye so they cancel each other out :-P. She gets funding from the Heartland Institute and the Science and Public Policy Institute both of which are ‘independent and non politically aligned’ “think tanks” which both get funding from the likes of Exxon[2][3][4], but hey girls gotta eat. (BTW fun factiod – The SPPI once produced a report in which they claim that sea levels have not risen, their evidence being a graph showing sea level rise, but tilted such that the long-term trend is flat. ).

But enough about her qualifications and onto her science, she quite often argues against herself, sometimes even in the same speech – she says warming is helping crops then later she says there is no warming[9](wrong on both counts). Other scientists disagree with both her methodology and her conclusions [10][11][12]

Lance Pidgeon

Looking for the correct Lance Pidgeon was going to chew up too much of my allotted 25 minutes, but from what I can see he appears mostly on the JoNova blog.

But now onto the actual article itself. Like I said the article includes a lot of links to newspaper articles, a lot of which do not provide any hard data just interesting stories. However as this was originally a webpage article the links served a simple purpose and that was to increase its SEO score[13] which is fair enough, when I post this to my blog I will also benefit from the same exposure and so capitalism lives 🙂

Now because my time limit on research is 25 minutes I will give general refutation of the article and not a specific one, if anybody really wants me to let me know and I will oblige.

From what I have been able to find 1896 was indeed a hot year, though both side of the argument dispute the recording of the various temperatures for the sake of brevity I will say yes indeed it was hot. So was the US in 1934 but one year in one geographical location does not a trend make [14][15]. This sort of thing is often used as ‘evidence’, other arguments used are

1. It is just part of a natural cycle, nope [16].

2. Volcanoes do more damage, nope [17] [18]

And so on and so forth, the simple fact is that in the field of CLIMATE science, the consensus is unequivocal: human activities are causing climate change[19]. So like I said I prefer to the climate Doctors not the Climate proctologists.

We have heard a lot about “the hottest year ever” and “hottest since records have been kept,” and it is presented to us a “clear evidence of global warming.”  A lot of what is written below seems to be researched from newspapers of the day and taken from the TROVE website as can be seen when clicking on the blue hyperlinks. One can only wonder what human interference caused the massive heatwave of 1896.Worth a read anyway,clip_image006
Extreme heat in 1896: Panic stricken people fled the outback on special trains as hundreds die.Post by: Lance Pidgeon with assistance from Chris Gillham and others.

It is as if history is being erased. For all that we hear about recent record-breaking climate extremes, records that are equally extreme, and sometimes even more so, are ignored.

In January 1896 a savage blast “like a furnace” stretched across Australia from east to west and lasted for weeks. The death toll reached 437 people in the eastern states. Newspaper reports showed that in Bourke the heat approached 120°F (48.9°C) on three days (1)(2)(3). It stayed above 100 degrees F (38.8°C) for 24 days straight.

By Tuesday Jan 14, people were reported falling dead in the streets. Unable to sleep, people in Brewarrina walked the streets at night for hours, the thermometer recording 109F at midnight. Overnight, the temperature did not fall below 103°F. On Jan 18 in Wilcannia, five deaths were recorded in one day, the hospitals were overcrowded and reports said that “more deaths are hourly expected”. By January 24, in Bourke, manybusinesses had shut down (almost everything bar the hotels). Panic stricken Australians were fleeing to the hillsin climate refugee trains.  As reported at the time, the government felt the situation was so serious that to save lives and ease the suffering of its citizens they added cheaper train services:

“The Commissioner of Railways promised a deputation of members of Parliament to run a special train every Friday at holiday excursion rates for the next month to enable settlers resident in the Western part of the colony to reach the mountains to escape the great heat prevailing.”  (Source)

It got hotter and hotter and the crowded trains ran on more days of the week. The area of exodus was extended to allow not only refugees from western NSW to flee to the Blue Mountains but also people to escape via train from the Riverina to the Snowy Mountains. The stories are heartbreaking. “A child sent to the mountains to escape the city heat died at the moment the train arrived.” “Six infants have died at Goulburn since January 1 through the excessive heat.” Towns were losing their esteemed, lamenting the loss of the good reverend, or of their well known miners. Children were orphaned.

A woman has been brought to the Bulli Hospital in a demented condition, suffering from sunstroke.  She was tramping the roads, with her husband, two days before, when she was prostrated by a sunstroke.  Her husband carried her through all the sweltering heat to Bulli, taking two days over the journey.” (Source).


Bourke circa 1900, National Library of Australia

The Victorian heatwave of 2009 was sold as the worst heat wave in southern Australia for 150 years.

In 1896 the heat was causing people to faint, become demented and was even blamed for driving people mad. “Several women fainted in the streets. A little girl, while walking along Surrey Hills, suddenly became demented through the heat.” In Bendigo “a young man named Edward Swift, hairdresser, was so overcome by the heat that he was unable to work, and in despair shot himself, in the breast. It is a hopeless case.” Longreach “police authorities at Longreach received information that a man who was insane was about fourteen miles out of the town.” “The bodies of people who die of sunstroke decompose very quickly”An axe wielding man in Bourkecut authorities at Longreach received information that a man who was insane was about fourteen miles out of the town.” “The bodies of people who die of sunstroke decompose very quickly”An axe wielding man in Bourkecut down three telegraph poles before he was “secured” by police. Presumably the real cause of the madness was something else, but the heat was the last straw. “Birregurra was stirred from its wanted sleepiness on Saturday evening last by the appearance in the streets of a mad man who caused no small consternation.”  It could be that nuttiness was equally common on other months, or other years. But at the time, people blamed the heat.

With this and people dropping dead in the streets from Perth through Adelaide to Sydney, the heat wave was described as being universal from west to east . It went north into Queensland and south throughVictoria.twice, by which time Australians considered themselves to be “Under Fire”.

Later in 1896, heat waves also occurred in India, Burma, Borneo, America. (It was bad in New York.  Listen here.) There was heat in England, Germany and Spain. 1896 was an example of extreme weather. [It was obviously the fault of the evil power stations, eh? Just 14 years earlier, Edison had built the first coal-fired electric generating station. If only people had understood just how dangerous it was. – Jo]

Thermometers were non-standardized in 1896. Some of the extraordinary temperatures come from thermometers with descriptions like (“under passion tree vine.”)  There it got to 123 in Ultimo in Sydney on January 14. Though some thought the vine thermometer was actually more accuratenamely, that what is known as the true shade is the shade afforded at the Observatory by one of the loveliest little summer-houses, almost buried in foliage, but with lattice-work all round, so that the breeze may play upon the thermometers, but where the sun’s rays can by no means be admitted.”.

Was the 2009 heatwave really worse than 1896?

The Victorian heatwave of 2009 was sold as the worst heat wave in southern Australia for 150 years. But it does not appear to be as widespread, as long, or as hot.  (Though caveats of comparing different thermometer placements apply — the old ones were in odd places, but the new ones are not necessarily well placed either, with some near airports, buildings and walls). What the newspaper records of 1896 show is that modern extreme heatwaves may not be at all unprecedented in temperature, severity and certainly not worse in terms of suffering.

“These events are unprecedented,” Victoria’s energy and resources minister Peter Batchelor said on Saturday. “In some respects, they are not unlike a natural disaster, impacting on a community like a flood or tornado.” (2009)

The Victorian heatwave began on Jan 25 2009 and broke on Jan 30. Deaths in Victoria were estimated at between 200 – 374. The population of Victoria in 2009 was about 5 million, about four times larger than thepopulation of NSW at the turn of the century. Death-rates are not a good indicator to compare the severity of heatwaves, as deaths in 1896 would have been less if air conditioners and modern hospitals had been available then.

How widespread was the heat in 2009?



The Wiki page associated with the above map, makes claims like “January 7th 45.2° C (113.4° F) – Hottest day recorded in Wagga Wagga since records began in 1941”. Records did not begin in Wagga in 1941. That was just when they began at the airport. In 1896 the temperature in Wagga Wagga got to 116.5° F or 46.9° C. It also points out that Melbourne for three days in a row had temperatures peak above 43° C. This is nearly the same temperature (109° F) that by midnight of the 22 Jan 1896 Brewarrina got down to.

How widespread was the heat in 1896?

Please note: As well as the caveats mentioned above, the dates given below may be inaccurate and the modern Australian definition of a heatwave  may not have been met in all locations.

This widespread:

Yalgoo W.A. Dec  25 1895 122° or 127° F “the Emerald Hotel, an iron structure” or at the Court House ” The latter structure is a ” wooden frame with duck covering.”;  Marra station N.S.W. 130 F on Jan 21. The link shows a full months record. “The figures were the readings of three different glasses, which were hung in the front verandah at the Marra, station, and were placed out from the wall on a frame to allow the air to get round them, thereby preventing the heat from the wall affecting the instruments.”; Berlino  S.A. 130° F  Jan 22. The thermometer “hangs on a stone house with a thickly thatched verandah facing West” … “never reached by the sun“. From Jan 5 to Jan 13, Berlino recorded many temperatures of 118° – 130° F; Kopperamanna Bore, via Hergott Springs S.A. “under date of January 23 : — ‘For the last month the heat here has been excessive.
