If only the $3 million dollar a day ABC could afford a science team that could do as much research as one unpaid volunteer does in a day?
Thanks to Cliff Ollier and Ken Stewart for the BOM graph of past Brisbane Floods. Clearly things were worse in the 1800s.
If CO2 has any effect perhaps it reduces flooding?
One day when the ABC finally gets the Internet they’ll be able to find official pages like “Known Floods in the Brisbane and Bremer River Basin“. And one day the half billion dollar BOM agency will be able to update graphs like this within a week of a new flood peak, like bloggers did (above).
Ken Stewart went looking for lost Rain Bombs and found them
As Ken reports the ABC made a fuss over three Queensland sites recording more than 1 metre of rain in just four days. But neither the ABC or the BOM is telling Australians that there have been at least nine similar “Rain Bombs” before and most of them were more than one hundred years ago.
I went looking at Climate Data Online for four day rainfall totals over one metre, to compare with the recent totals above at Mount Glorious, Pomona, and Bracken Ridge. For a start, Pomona’s BOM station has been closed for years, and Bracken Ridge is not listed at all, so those reports are from rain gauges external to the BOM network and can’t be checked. That’s OK. In about half an hour I found the following four day rainfall records.
| Crohamhurst | 4/2/1893 | 1963.6mm |
| Yandina | 3/2/1893 | 1597.8mm |
| Tully Sugar Mill | 13/02/1927 | 1421.3mm |
| Palmwoods | 4/2/1893 | 1244.6mm |
| Buderim | 3/2/1893 | 1150.3mm |
| Bloomsbury | 20/01/1970 | 1141.8mm |
| Dalrymple Heights | 6/04/1989 | 1141mm |
| Innisfail | 3/04/1911 | 1075.8mm |
| Nambour | 11/1/1898 | 1013mm |
1893 was a wet year! Crohamhurst had 2023.8 in five days, and Brisbane had three floods in two weeks in February and another in June.
And there is no such thing as a “rain bomb”, a term invented to make it sound unprecedented. This was an entirely natural and normal rain event. Slow moving tropical lows drift south every few years in the wet season, producing a large proportion of Queensland’s average rainfall.
It’s another Red pill moment. Spread the news. Australians need to know the media and the BOM are not giving them the whole truth. Has anyone in the BOM called up the ABC and corrected their mistake? Isn’t that their job?

Bullshit detection from fact-cherry-picking non-scientific Ken Stewart
• Yes slow moving low system are possible for making rainfalls as big as this year in history, not denied
• in the 1800’s the majors rivers like Brisbane River, Hunter River, etcs were 1/3rd of the width and 1/10th of the flow. In the 1800’s flood plains were very extensive and slowed water moving downstream, and the 1800’s rainfall would take “weeks to reach the sea” compared to “a few days” nowadays.
• less floods in last 100 years may be due to dredged river and man made stormwater drains, and drained swamps so you can’t correlate to CO2
• The use of one piece of data to then hypothesis that CO2 is not a factor in a multi-variable scientific analysis, is an unscientific myopia of troglodytes
• I can cherry pick some counter facts too, like for every one degree increase in air temp the air holds 3-5% more water in the clouds based on laws of thermodynamics which then can fall at twice the rate to earth – refer https://www.engineeringtoolbox.com/maximum-moisture-content-air-d_1403.html

I think if you look at Jo Nova’s site, it’s hardly cherry picking. There is a context.
Also the mainstream media and the climate change lobby are constantly using words like “unprecedented”, “catastrophic” and so on to hype their agenda.
The floods of this year, like the bushfires of two years ago are hardly unprecedented or unique events caused solely by CO2.
