A year ago I wrote about the odd link between the Hunga Tonga volcanic dust and floods in Australia, but perhaps volcanic dust also played a role in the savage rain bombs of 1893 that caused the infamous floods of Brisbane?
After Hunga Tonga erupted last year, about a week later unusually heavy rain started falling over Australia — even washing out the Indian Pacific Railway line connecting East and West Australia. A month later and the dust had gone around the world and returned to give us glorious sunsets followed by more rain bombs.
So it may be just a coincidence, but the second heaviest Australian rain bomb was on Feb 3, 1893. And three weeks earlier on January 7th the Calbuco Volcano in Chile had its largest eruption in the last 130 years?
In 1893 an astonishing, flabbergasting day occurred, where 907mm of rain dropped from the sky on Crohamhurst in Queensland (that’s nearly 36 inches!). It came in an astonishing week, where the heavens dumped 2 meters […]
If Climate Change was a real threat, the Bureau of Meteorology might even look at their own historic records.
When Jennifer Marohasy and Chris Gillham did just that, they found that as bad as the current situation is, it’s happened before:
The wettest day in Lismore was in February 1954. The wettest year for Lismore was 1893. There was no increase in the intensity or frequency of extreme wet days at Lismore, or the towns around it.
Now if the BOM looks at this with a supercomputer, they might find an effect from CO2. But if the BOM just used a calendar, like I did, they might find the latest floods started the week after Hunga Tonga volcanic dust rolled across Australia. Maybe that matters?
No one needed a supercomputer to read a rain gauge in 1885, and we have excellent long data. Imagine how handy that might be if the BoM wanted to understand, say, Australian flood cycles? There are 137 years of rainfall records in Lismore from 1885 to now, but the BOM said we set a new record for Lismore based on Lismore airport where records started as long ago as… 2002.
The Bureau […]
Hunga Tonga-Hunga Ha’apai
By Jo Nova
Unusual rain in Australia started within days of the Hunga Tonga dust cloud travelling across the continent
On January 15th, Hunga Tonga launched a magma-powered thunderstorm that sent atmospheric shockwaves around the world. Ash, salt and particulates were carried through rising columns, right through the stratosphere, into the mesosphere and all the way up to 58 kilometers above Earth. For hours 400,000-odd lighting bolts zapped the airborne chemical soup.
The dust from Hunga-Tonga travelled West and reached Australia on Jan 18 – 20th. On Jan 21-22 flooding rain washed out the main railway line and roads in central Australia. Over the next few weeks, rains soaked the ground across parts of Queensland and New South Wales. By February 15th, the remnant volcanic dust that had circled the Earth and was back again creating rich red sunsets over Australia. A week or so after that, the rain bombs fell on South East Queensland, and travelled south through New South Wales to Sydney.
The big unknown is that the Hunga-Tonga volcano launched water vapor, salt and dust incredibly high — almost too high. The aerosols are far above the troposphere where rainfall originates and […]
Here’s one for all the history-deniers from 1885
Mr N Bartley understood Australias climate 134 years ago better than some climate scientists appear to now.
After the fire came the floods, Feb 2020.
Even then Australia already had a century-long rolling cycle of floods, fires and droughts. One natural disaster after another back when CO2 levels were perfect.
These go back to the earliest dates of European settlement. Wherever Captain Flinders landed in 1782 — 1792 he found “found traces of drought and bush fires invariably”. In 1839, the drought was so bad that fish “putrefied” in the big Murrumbidgee River even though there was not one coal fired power plant on Earth.
The author laments that the droughts “become forgotten in the flood intervals.”
In the modern Wifi era humans can forget even faster.
Below is my summary list of the events described in the story.
Below that, the full letter. From The Queenslander, Sept 19th, 1885.
*Since Captain Flinders was born in 1774 I assume those dates were wrong and he wasn’t commanding a ship when he was 8 years old. Any other suggestions welcome.(thanks Gee Aye, SteveD, James West and Peter Fitzroy)
(1795 onwards?)* […]
More lies by omission from the Bureau of Misinformation
When a PM gets it totally wrong, where is the BOM…
“What this royal commission is looking at are the practical things that must be done to keep Australians safer and safe in longer, hotter, drier summers.” — Scott Morrison. — ABC
The BoM, like Prof Andy Pitman of UNSW, and all other climate scientists know that “climate change” will make the world a hotter wetter place. Who are the evaporation deniers among us? Yet, apart from one momentary candid admission from Professor Andy Pitman, which of our paid public servants will correct the PM when he says things that are flagrantly, 100% wrong? Will a Royal Commission really be forced to accept a complete myth?
Looks like extra CO2 “causes” Summer rainfall in Australia to increase
Apparently, we should burn fossil fuels to stop fires. You know it makes sense…
Australian rainfall trends, Bureau of Meteorology,
But wait, what about Southern Australia?
To cover every last caveat, it’s possible that “climate change” could change where rain falls, or when rain falls — so lets look at the BoM’s own rainfall records.
CO2 apparently makes summers wetter across […]
When will our BoM and Climate Experts correct the Fake Science and misinformation?
Climate change leads to a hotter-wetter world. This is a central canon of the theory of man-made global warming. Despite that, none of our paid experts are correcting the myths and misinformation of our public debate. Every man and his monkey (including M.P’s) are saying that Climate Change causes a hotter drier world which leads to fires, and the BOM, CSIRO and millions of scientists apparently agree. So if Australians are misinformed, who’s fault is it? — Not looking at you Andy Pitman, David Karoly, Tim Flannery, ABC Science Unit, Gergis, Sherwood, Trewin, Steffan and all the rest.
Blame the ocean currents for our bush fires
The biggest cause of bush-fires in Australia is the drought. A lack of rain allows the nation to get scorching hot days and dries out the fuel. Yet our long term records show that obscene megatons of CO2 from China has no detectable effect on our long term rainfall. Not in the fire zones, and not across the whole country either. The main driver of droughts and fires therefore is the El Nino oscillation, the IOD, and the SOI. Tax […]
The obvious headline:
“Worst drought in history was 100 years ago, nothing to do with CO2”
The Carbophobic headline:
Drought of 1891 to 1903 reconstructed shows today’s conditions likely to have more devastating effects
Indoctrinated ABC copy-writers can’t see anything other than future doom and a chance to advertise the government religion. Figure that the Australian GDP per capita is 13 times larger now than in 1900. We have phones, planes, antibiotics, air-conditioning, satellites, and super computers, yet somehow we wouldn’t cope as well if the drought hit now?
It’s great, for a change, to see the ABC reporting on historic Australian extremes, and the BOM researching our amazing documentary history, shame they miss the bleeding obvious.
By Nikolai Beilharz, ABC Enviro-propaganda Unit.
A reconstruction of the Federation drought has found that if it were to occur again today, its effects would likely be even more devastating in some areas of the country.
The ‘once in a century drought’, which went from 1891 to 1903, caused an ecosystem collapse affecting more than a third of the country. The drought was one of the world’s worst recorded ‘megadroughts’, which […]
Remarkable! A new study by Ashcroft, Karoly and Dowdy pieces together an extraordinary 178 years of rainfall data from Sydney, Melbourne and Adelaide. This is a rare study that brings in much older data, looking at trends and extremes. This is pretty much the ultimate long term rainfall paper for South East Australia. Henceforth, there shalt be no more headlines about “unprecedented” rainfall or area’s drying out “due to climate change” unless an event rates against this data…
Australia – a land of floods and droughts: Rainfall goes up and down in long ongoing cycles or change, but no obvious trend that matches the sharp rise of CO2 in the last 30 years. It’s almost like CO2 has no detectable effect… The worst extremes were for the most part — long ago — particularly in the 1840s (assuming those records are reliable). Almost nothing in the last 30 years is unusual or unprecedented despite humans putting out 50% of all our CO2 since 1989. These charts show how misleading it is to use graphs that start in 1970 (or even in 1910) and declare that the recent changes are meaningful, or caused by CO2.
The researchers also use newspaper archives […]
Warwick Hughes (h/t Dave Brewer) points out that on Dec 20th the Australian Bureau of Meteorology predicted that the Townsville region had only a 1 in 3 chance of exceeding the average rainfall in January.
Australian Bureau of Meteorology, prediction, Jan 2019 rainfall.
…
How that turned out one month later:
Australian Bureau of Meteorology, January rainfall, 2019.
Or graphed as the rainfall anomaly rather than as the percentage of the mean:
….
Predicting rainfall in Australia is very difficult. The issue is not that the BoM gets it wrong — it’s that they pretend they can do it that matters. Why bother issuing one month forecasts?
Ten days out they were still hopelessly wrong
As Warwick Hughes notes they also predicted on Jan 17th that February in Townsville would only have a 45% chance of exceeding the average rainfall. The downpour started on Jan 27th.
Today, after one whole week in February, the area has already had over four times the normal rainfall for the whole month, but the BoM didn’t see that rain coming ten days in advance.
The fancy-pants detailed graphics are entirely misleading — like advertising that sells an ability the experts simply […]
After epic flooding in Townsville, witchdoctors are blaming climate change.
Queensland’s recent extreme weather – bushfires, heatwaves, coral bleaching, drought, Cyclone Penny, Townsville’s floods – showed Queensland is clearly experiencing climate change, Professor Ian Lowe said.
Thus spake the Druid of Runes waving a bunch of multifactor complex processes that have been happening forever, can’t be predicted and only have scary trends if you draw short graphs with no error bars. Verily we see doom, doth payth my grant, or whatever it is that keeps Prof Ian Lowe going. He is allegedly in the Queensland Climate Advisory Council (QCAC) — an organization so successful its only existence on the internet appears to be a sidebar on page 15 of a government PDF. But whoever they are, they’re experts, trust us, that the media doesn’t need to ask for an alternate opinion.
Wouldn’t you know it though, floods seem to happen quite a lot in Townsville
This is not to say that the current floods are not serious but just that Townsville is a floody kind of place. It’d be climate change if things stopped flooding in Townsville.
In the last ten days Townsville has had 600mm […]
A funny thing happens when you line up satellite and surface temperatures over Australia. A lot of the time they are very close, but some years the surface records from the Australian Bureau of Meteorology (BOM) are cooler by a full half a degree than the UAH satellite readings. Before anyone yells “adjustments”, this appears to be a real difference of instruments, but solving this mystery turns up a rather major flaw in climate models.
Bill Kininmonth wondered if those cooler-BOM years were also wetter years when more rain fell. So Tom Quirk got the rainfall data and discovered that rainfall in Australia has a large effect on the temperatures recorded by the sensors five feet off the ground. This is what Bill Johnston has shown at individual stations. Damp soil around the Stevenson screens takes more heat to evaporate and keeps maximums lower. In this new work Quirk has looked at the effect right across the country and the years when the satellite estimates diverge from the ground thermometers are indeed the wetter years. Furthermore, it can take up to six months to dry out the ground after a major wet period and for the […]
South West WA and Perth have been the Australian posterchild for Water-Panic for years.
We were destined to be an abandoned ghost town with worthless property:
Perth is set to become the world’s first ‘Ghost City’ according to a long-term weather forecaster and a news anchor. “I’m reading here that unless drastic action is taken, Perth could become the world’s first ghost city – a modern metropolis abandoned by the 1.7 million people there for lack of water,” she said.
Tim Flannery started the Ghost Town scare in 2004. He felt the best way to fill WA dams was to vote for emissions reductions.
As I write, the remnants of a small cyclone are raining down on us in midsummer, which the ABC earlier warned was a “deluge” dropping “three months of rain”. What they don’t mention is that, even before this “downpour” (of 90 mm or 4 inches so far), Perth Dams already have 35% more water than at the same time last year, and an extra 69 gigalitres of the precious wet stuff. We have more water than we’ve had since 2009, and more is on the way.
WA Water corporation data shows Perth Dams have […]
It is not surprising there are floods all over the East coast at the moment
September brought 500% of normal rain to 2 million square kilometers of Eastern and Northern Australia. There are floods across the South East. There are flood alerts in South Australia, floods have been washing through NSW (and some of those floods were caused by a dam release). There are floods in Tasmania. Flood watches are active in Victoria. Spare a thought for farmers who are taking big losses from both frost and flood in Australia. (So much for endless droughts, and early springs. Hello, Tim Flannery.) Heavy snow has also fallen — 25cm in Threadbo (it so late in the season, some ski lifts have stopped operating). Right now, thousands of people still don’t have power in South Australia, while others are being rescued from floods across SA and NSW. Floods have stranded 181 families for month on islands in the middle of NSW.

A large part of the scary purple area got only 100-200mm of rain in a month (4-8 inches). It’s just very unusual in these dry areas.

A study done on… golly, Antarctic Ice, allegedly shows that in the catchment area for Newcastle in NSW, Australia, the last 100 years have been pretty darn nice, compared to the past when droughts and big-wet periods used to last a lot longer.
Set aside, for a moment, that the ice cores are thousands of kilometers away and in a totally different climate, if they are right, if, then natural climate change is much worse than our short climate records are telling us. And if our current records are so inadequate and don’t represent the “old-Normal”, then we have a flying pigs of predicting the “New Normal”. Has the climate changed at all, or is the new one just like the old old one?
Hydroclimatologist and lead author, Dr Carly Tozer from the ACE CRC said the research showed exposure to drought and flood risk was higher than previously estimated.
“The study showed that modern climate records, which are available for the past one hundred years at best, do not capture the full range of rainfall variability that has occurred,” Dr Tozer said.
“The wet and dry periods experienced since 1900 have been relatively […]
The headlines are out, telling us the unnerving news that the climate has changed, “zones are on the march”. How ominous.
Too-tricky graphs show how different everything is in the last 16 years “compared to the 99 before that”. But since our weather comes in cycles of 30, 60 or 200 years, as well as longer ones, almost any 16 year period is likely to be not the average of the century beforehand. Thus this technique can be applied to any noisy cyclical dataset as a Handy Headline Generator.
It’s a tad shameless to present it as if it means something given our short knowledge of the Australian climate and the hyper variability within. You’d think our last century had a constant climate, then there was a “shift”. Spot the hockeystick?

Is someone graphing noise?
In thousands of kilometers across the pink “summer dominant” areas of central Australia, it might rain more in summer, but it mostly doesn’t rain at all and when it does rain properly, it’s once in a decade. See Alice Springs in January. How’s that for noise? Did a remnant cyclone rain on Alice this year?

Blame dry weather and electronic sensors for a lot of Australia’s warming trend…
In this provocative report, retired research scientist Bill Johnston analyzes Australian weather records in a fairly sophisticated and very detailed way, and finds they are “wholly unsuitable” for calculating long term trends. He uses a multi-pronged approach looking at temperatures, historical documents, statistical step changes, and in a novel process studies the way temperature varies with rainfall as well.
His two major findings are that local rainfall (or lack of) has a major impact on temperatures in a town, and that the introduction of the electronic sensors in the mid 1990s caused an abrupt step increase in maximum temperatures across Australia. There will be a lot more to say about these findings in coming months — the questions they raise are very pointed. Reading, between the lines, if Johnston is right, a lot of the advertised record heat across Australia has more to do with equipment changes, homogenisation, and rainfall patterns than a long term trend.

According to the ABC the Bureau of Met tells us that Queensland has experienced “the worst drought in 80 years” and that “37.3% of the state was covered by the lowest rainfall on record”. (Watch it on iview if you can bear to).
These exacting facts are easy to check, and Ken Stewart did, but the 1.1-billion-dollar ABC did not.
Ken used the BOM’s own websites (Climate Maps and Climate Change and Variability) and shows that the current drought is the worst in 9 years, not 80, and even if it is very bad (heartbreaking for some) it’s not unusual.
Current low rain is not unusual.
The current drought is bad (see red blobs in Queensland):
NW Queensland has missed two wet seasons in a row
The Federation Drought, circa 1900, was much much worse:
(Federation Drought graphed only 1900 – 1902)
Ken wrote to the ABC, and Genevieve Hussey replied immediately — effectively saying the ABC repeat all BOM claims, no matter how hyperbolic, extraordinary, or repetitive they sound.
The information in our report was based on an interview with climatologist Mr Jeff Sabburg from the Bureau of Meteorology. He was also interviewed by […]
A new study of Law Dome Ice cores tells us that droughts are common in Australia, and that there appears to be eight mega-droughts over the last thousand years, including one that lasted a whopping 39 years from 1174- 1212AD. By their reckoning the 12th Century in Australia was a shocker with 80% of it spent in drought conditions. Things weren’t so bad from 1260 – 1860, at least, as far as they can tell. The researchers are convinced theirs is the first millennial-length Australian drought record. It does seem significant.
The researchers, sensibly, think we might want to pay attention to the Pacific cycles and store a bit more water. Without fanfare the paper also suggests that droughts were worse in medieval times.
“this work suggests Australia may also have experienced mega-droughts during the Medieval period that have no modern analog. Therefore, management of water infrastructure in eastern Australia needs to account for decadal-scale droughts being a normal feature of the hydrological cycle.”

The ABC reported this largely as a water management story, without asking whether their past stories that blamed CO2 for droughts were less likely to be true. […]
A major stormfront in NSW has dropped 170mm on rain on Ulladulla, ploughed down trees, drove waves 8m high onshore, and put the airport underwater in Sydney. It has carpeted the Blue Mountains in 20cm of snow. 30,000 homes lost electricity and 60 people were stuck in a train for two hours. This time last year the region was burning. Amazing photos at the Daily Mail.

A new study by Steinke shows that the sun could have been a driver (somehow) of some of the monsoonal rain changes over the last 6,000 years over Indonesia and Northern Australia. h/t to The Hockey Schtick
In the spirit of the Perfect ClimateTM that existed prior to Henry Ford, we also find that Indonesia had a dry spell that lasted for a while, like say, 3,000 years. It ended about 800BC whereupon things got wetter, and mostly stayed wetter. The authors (Steinke et al) think this might have something to do with solar minima which was very low 2800 years ago. (Though I note the Greek Dark Ages also finished then, and “city states” arose, right, so it could have been that too. Ahem?)
To get straight to the action in Figure 6 the top squiggly line is AISM Rainfall (that’s the Australian-Indonesian summer monsoon). It shows how things were wetter in the last 2800 years ago and drier before that (annoyingly, the present time is on the left). The second part of the graph in red shows sunspot numbers. That gets flipped upside down and superimposed on the rainfall graph in the third part, and we can see […]
