Australians wiped out the flu and avoided 50,000 other cases of sickness and disease

Lessons from Coronavirus

Lockdowns and border closures mean many diseases have been prevented

It’s peak season for flu here in Australia and there’s almost no sign of it. As Chris Gillham wrote here back in May, we know lockdowns stop viruses, because flu cases are 85% down. Now he shows that this extends to other diseases too, and Chris has used data from the National Notifiable Diseases Surveillance System to calculate that just shy of 200,000 fewer Australians contracted any of the notifiable diseases in the first seven months of 2020 compared to the first seven months of 2019.

Is some of that disease burden just the price of holiday-makers bringing back diseases from overseas each year?

No one wants to stop the planes returning to the skies, but it begs the question — do we have to accept the onslaught of winter germs every year?

The answer may lie with other things we’ve discovered in the Covid pandemic too — that sick people should stay home from work and school, and that we have a lot of anti-viral tools we can use. Perhaps it’s time that travellers considered taking preemptive anti-virals, which might improve their holidays and also reduce [...]

Lockdowns work: Influenza cases are 85% down across 17 countries

Lockdowns appear to be reducing all flu-like diseases

This years flu season is smaller than the last five years

Good news: due to the pandemic it’s likely many people are not catching Influenza and other respiratory diseases.This shows a rather predictable result that quarantine reduces the spread of respiratory diseases. It’s a banal and uncontroversial finding.

Chris Gillham is a part of the unofficial BOM audit team here, and below he looks at WHO data across 17 countries for Influenza. (The WHO Chief of course is a belt-n-debt-trap apologist for China, but this is not their modeled interpretation, just the data). Laboratory indicated influenza cases are down an astonishing 87% in 17 nations compared to the five year period.

Quarantine is textbook microbiology, and for most of history, the best way to reduce the spread of disease. In many countries 12 days after major isolation measures started, viral growth flattened off the dreaded exponential curve. Despite that, some commentators still wonder if the lockdowns achieve anything for Coronavirus. And so it is, that we reach this strange point in the debate, where it is worth stating the blandly obvious: that lockdowns slow the spread of respiratory viruses. This is [...]

ACORN adjustments robbed Marble Bar of its legendary world record. Death Valley now longest hottest place

UPDATE: The Hon. Craig Kelly MP was so appalled by this story he has taken this to the Australian Parliament already where The Labor Party was so afraid they interrupted his allocated 15 minute speech just to stop him finishing. They even called a formal Division which means the bell is rung and all the missing MPs have to return to the Chamber to vote. See that on Kelly’s Facebook page. Who cares about our climate and who covers up for incompetent bureaucrats?!

For generations it was a Guinness Book of Records type thing. Now it’s gone. In 1924 Marble Bar set a world record of the most consecutive days of 100 °F (37.8 °C) or above, during an incredible period of 160 days starting in 1923. It was legend — but thanks to the genius homogenized adjustments, we now find out all along it was wrong. It’s another ACORN triumph, rewriting history, extinguishing the hot days of days long gone. The experts at the Australian Bureau of Meteorology (BoM) have reanalyzed the temperatures from 4000 km away and nine decades in the future and apparently it wasn’t that hot.

Chris Gillham wonders how the bureau figured out the Marble [...]

Cricketers to freeze: Boxing Day Tests in Melbourne cooling since WWII

Peacetime maximums on Boxing Day are just not what they used to be

The ABC is afraid that Boxing day cricket may “go extinct” due to the heat. Chris Gillham at WAClimate.net graphed the December 26 test temperatures in Melbourne all the way back to 1855. Obviously, using ABC-ScienceTM (absurdio-extrapolatory et al) what we are really looking at is ominous cooling. To help the ABC, let’s adjust headlines accordingly.

“Injuries are forecast to rise as maximum temperatures fall in Melbourne on Boxing Day.”

The trend is clear in a supercomputer somewhere. If this decline continues the second polynomial will hit zero in 440 years. Cricketers won’t know what heat is.

The graphs here confirm the newspaper stories of a history of phenomenal Boxing day heat – especially in the late 1800s and circa World War II. Ergo, wars cause global warming (in Melbourne, on Dec 26).

…This is bound to change…

Two things to keep in mind, apart from designing a team beanie, is that many of the temperatures in the 1800s weren’t from Stevenson screens and so are debatable. On the other hand, the urban heat island effect is strong and site maintenance is weak, so [...]

Raw Data Bombshell: no change in Very Hot Days in Australia since World War I

What a bombshell. Despite the non-stop stories of unprecedented heat the original data at 60 of the oldest sites across Australia shows there are no more Very-Hot-Days now than there were early last century. That’s no trend in 40 degree days for 100 years. No change – that is, until the Bureau of Meteorology adjusts the data…

After we were shocked at the latest ACORN changes to our Very Hot Days data, I asked Chris Gillham if we could see the effect of Bureau of Meteorology changes to the original raw data – and he replied it would be too time-consuming writing the code to calculate 40C+ days among the millions of daily temperatures from 112 weather stations across Australia since 1910. Then he did it anyway.

Wow. In 2011, the BoM’s ACORN 1 adjustments wiped out some of the “very hot days” recorded at weather stations in the early 1900s. These were records that had stood for a whole century. Then, quietly six years later, the ACORN 2 readjustments turned the statistical air conditioner on again and cooled people from 100 years in the future.

It’s all especially miraculous given that even the old World War I data [...]

Who knew? The Australian Bureau of Met just made last summer hotter, and history colder (again)

The cheapest way to prevent man-made global warming is stop the BOM altering the data

First the BoM had “high quality” data. Then, with fanfare, after we asked for an audit they had the miracle of ACORN circa 2011. Then early this year ACORN 2.0 was quietly birthed with major adjustments as expert data became “more expert” but the BOM strangely didn’t want to mention that what was so good is now even better (apparently). The unofficial BOM audit team — especially Bob Fernley-Jones and Chris Gillham — have unearthed just how large the latest rewrite of history is. These men are truly independent, they have no funding, and nothing to gain either way. Please thank them for their unpaid dedication.

In this brazen latest round, even the summer of 2018 just got warmer. After all the headlines, after it was measured on supposedly modern first class equipment, even data just 18 months old is being re-fiddled. The temperatures read out on the news in January 2018? Nevermind what they said then. Those hottest ever records then were even hotter than the BoM thought, thanks to amazing new discoveries that the BOM doesn’t think are important enough to issue as [...]
