ABC, Climate experts do damage control on 1896 heatwave story, can’t say why, but they “know” it was cooler. Faith!

Winning! The 1896 heatwave story is going viral and the ABC is reduced to weak, late excuses

Australians are realizing that our hot history has been hidden from us. We’ve set a new site traffic record with around 100,000 people checking in since Wednesday, plus thousands more reading the story elsewhere like Catallaxy and Facebook. Thank you for sharing! We first posted the 1896 heatwave here first in 2013, then again on Wednesday. The ABC has gone into damage control responding with a direct attempt to rebut the story, but they are too scared to name this site. What are they afraid of?

We, of course, have no such fear. Six years after skeptics let Australia know about the 1896 heatwave, the ABC and “experts” finally catch up but only under duress. So now they mention it, but use vague caveats, distractors, discuss different time spans, ignore 49 other hot sites, appeal to authority, and don’t mention their own recent artificial site changes that skeptics have documented in more detail than the BOM have. The “experts” allude to “thermometers on beer crates” but in Bourke the heat was recorded at the post office on Oxley st. Skeptics are well aware [...]

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 [...]

The Bureau of Met disappears “Very Hot Days” graph showing the most hot days in 1952

Here’s an inconvenient fact: Australia had the highest number of very hot days in 1952, back when CO2 levels were 311ppm and humans had not yet emitted 87% of our carbon dioxide emissions. Something else was causing that extreme heat. If only the modelers knew what it was?

For years the BOM site had this informative graph below, but yesterday Craig Kelly M.P. phoned me to prepare for his Bolt Report appearance and informed me the Bureau had dropped it down the memory hole. It used to be a tab available on their Track climate trends and extremes page. Apparently in this era of global warming, the BoM doesn’t think Australians care about the trends in days over 40C in Australia, or perhaps it didn’t fit the agenda? On the Bolt Report last night Kelly explained that according to the Wayback machine, it disappeared sometime during the election campaign this year. (It was there on March 26th and gone on March 28th.)

Thankfully Paul Homewood of Notalotofpeopleknowthat kept a copy:

There’s not much a of a trend in the average number of very hot days (greater than 40C) each year in Australia. | Source: Australian Bureau of Meteorology [...]

Climate disasters are less costly, less deadly, and corporate warnings are just $1T of hot air

Hitting the presses today, the vacuous news that lots of companies picked huge numbers out of the air using broken models to guess hyperbolic climate losses coming in the next five years, counter to all the trends for the last hundred years which show declining losses on a GDP basis. The world got warmer but the disasters got less nasty. Less bushfire, less cyclones, less tornadoes, less death per capita. The trends are all good. The only thing that’s up is the number of panic merchants.

World’s biggest firms foresee $1 trillion climate cost hit

LONDON (Reuters) – More than 200 of the world’s largest listed companies forecast that climate change could cost them a combined total of almost $1 trillion, with much of the pain due in the next five years, according to a report published on Tuesday.

So hundreds of companies have offered the climate world a free hit for PR by making a guess. They fall into two kinds of companies –The badgered and harried and the profiteers. See below for examples. Firstly, here’s the only chart that matters.

Global Weather losses are down:

If CO2 causes climate events we need more of it. The [...]

Poll shows Australians are more skeptical of extreme drought, flood and fire voodoo

The message that CO2 causes fires, floods, storms, reef damage and refugees is wearing off

What a problem for the vested interests — it’s their main propaganda message.

It’s witchcraft:

When the witchdoctors ran out of long term trends and supporting evidence they started blaming every storm on CO2. It was a sign of desperation. In more respectable days they would say these were “weather” not climate trends. Storms, floods, droughts and fires are caused by many variables, none of which the climate modelers can predict even ten days in advance. Furthermore, huge 1 in 100 year events need a thousand years of data (at least) before we could pretend to have even a hint of statistical significance that they are not just natural events which have always happened and always will.

About 10% more Australians have woken up

New polling shows that about 1 in ten Australians that used to find this witchcraft convincing are smelling a rat and don’t believe it anymore. Back in 2015 when IPSOS asked the exact same climate change question 62% of Australians thought that climate change was already causing more droughts. Now after a vast drought, it’s only 52%. In 2015, 61% of [...]

Townsville floods again: 1881, 1892, 1946 and 1953. It’d be climate change if it stopped flooding

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 [...]
