Adjusted! Another degree shaved off Darwins history — (it’s cooling so fast, in 50 years Darwin won’t even be tropical)

Graham Lloyd and Jen Marohasy scorch through the BoMs latest revision of Darwin.

On the 1st of January 1910 the maximum temperature recorded at the Darwin post office was 34.2 degrees C, then it became 33.8 C, and now it was, is, 32.8 C. (What’s the past tense of something that is now, but wasn’t then? We don’t even have grammar for this.)

Extrapolate that adjustment trend: One degree of cooling in 6 years (since the last adjustment) becomes 16 degrees cooler in a century. Darwin won’t know what hot days were!

Look what they’ve done to history Mum

The Bureau of Meteorology has no interest in the hot pre-1910 era which just gets chopped. And even if they did include it, after they’ve adjusted it — it wouldn’t be hot anymore anyway. Remember the Federation Drought? No one else does either.

Temperature is whatever you want to make it.

Mean maximum annual temperatures as measured at the Darwin Post Office and airport shown with the new remodeled ACORN-SAT Version 2, which is the new official record for Australia.

“What the Bureau has done to the historical temperature record for Darwin is indefensible. ” –– Marohasy

Fewer heatwaves for 9 million Australians in Sydney, Darwin, Hobart, Melbourne –“thank CO2”!

Let’s play the Heatwaves PR game. If CO2 had an effect we’d see a significant increase in the rate of global warming over the decades since WWII, the models would work, and climate scientists would be able to predict our climate. Since none of that is true, those with a political agenda have to clutch at noisy but marketable extremes instead. Apparently even a half-true, noisy, non-causal link is good enough for post-modern scientists.

Heatwaves are perfect for generating scientific sounding fear, but not so useful for generating actual scientific knowledge. There are an infinity of ways to measure them. They can last 3 days – 160 days, and be cut off at any number from 35 – 40C, or at some percentile outlier. They can be measured one town at a time, or on a regional or state-wide level. The permutations are rich with headline scoring possibilities. And in the end, on a long warming trend that started 300 years ago, it is obvious, inevitable, and predictable that we should score more now. What’s surprising is how often we don’t.

On ABC radio before Easter, Dr Vertessy, Director and CEO of the Bureau of Meteorology, claimed that we are […]

Worldwide Rally for Freedom 5.0 — Protest this Saturday

Freedom to choose our own medical treatments with our doctors without corcercion

Freedom for doctors to prescribe the best treatments they can without fear of being sacked

Worldwidedemonstration.com #FreeAustralia AustraliaFreedomRally.com

Commenters please add links to your local events or national information pages. France: #Liberte

Rallies start at 12:00 at the following Australian locations:

Adelaide: Rundle Park |Brisbane: Brisbane City Botanic Gardens | Bundaberg: Lions Park | Cairns: Muddys Northside | Darwin: The Esplanade (15:00 ACST) | Gympie: Lake Alford Park | Hobart: Parliament Lawns | Mackay: Bluewater Quay? | Melbourne: Parliament House | Mt Gambier: Vansittart Park | Perth: Forrest Place | Sydney: Hyde Park | Townsville: Strand Rockpool | Warrnambool: Civic Green

I suggest people subscribe on Telegram for information and to find a local protest. More info here.

UPDATE: Obviously, all protests need to be peaceful. Not only is violence bad in and of itself, but it works against everything the protest aims to achieve. It only serves those who want to create division, paint the protesters as dangerous, and distract the world from the polite and civil pleas for simple medical freedom. In fact […]

A miracle? CO2 at record highs but Australia’s risk of Megafire Summer reduced

Global carbon dioxide levels hit record highs in 2020. But through incredible luck, or perhaps a Pacific La Niña event, Australia is now less likely to get massive bushfires this summer.

Looks like carbon dioxide will now cause more floods and cyclones, not fires and droughts.

It’s just physics, you know.

La Niña set to bring cooler weather, more rain and cyclones to Australia

Lisa Cox, The Guardian

The last La Niña occurred from 2010-2012 and brought widespread flooding and record rainfall. The Bom said its modelling currently suggested the latest event would be strong but would not reach the same intensity.

[Andrew] Watkins said La Niña would likely bring increased rainfall in both northern and eastern Australia and increased risk of flooding. It also raises the chance of increased cyclone activity during the tropical cyclone season, with a typical season being nine to 11 cyclones.

He said an active La Niña would also reduce the bushfire risk this season slightly, but would not eliminate it.

Dr Joelle Griggs, a climate scientist at Australian National University, reminds us that even in La Niña years sometimes early rain produces bulk grass which, if […]

Crushing the Curve in Australia — “unknown source” covid cases trending down

Australia remains the star Lucky Country compared to overseas. Infections are low, deaths are even lower. It’s all so much better than the desperate situation in Europe and the US. These are enviable, fantastically small numbers. Politicians are afraid to say so, lest the population relax, and party too much this Easter and the “unknowns” increase. (Which might well happen).

At the moment, the trend that matters most is the daily new cases of unknown transmission and it is trending down. There is community spread, but social isolation is shrinking it. This is what “Crushing the Curve” looks like. Right now there are still asymptomatic spreaders out there, but they are infecting less than one other person each (Ro < 1), so the infection is on its way to extinguishing itself — assuming we keep up the distancing.

But these great figures are not a reason to let up on social isolation, they’re a reason to go harder. We want to achieve the Golden Holy Grail — no new infections, and business as usual with no lockdowns, no curfews and a zone of freedom.

Australia is the Lucky Country, and doing the right thing

Why is the situation so good […]

Hottest ever day in Australia — especially if you ignore history – Eg. 1896

Tuesday was Australia’s hottest day on record sayth the Bureau of Meteorology.

And perhaps it was. But look at the temperatures reported in newspapers across the country during the month of January in 1896 when people were going mad with axes, dropping dead in coaches and railway stations and birds were falling lifeless from the trees? Emergency trains were ferrying people from the country to the mountains. Panic stricken people fled the outback on special trains and the death toll was in the hundreds.

Fifty years later scientists would publish papers talking about how Australian summers had cooled since then.

How does the BOM know for sure that it was not hotter on any one of these days? Perhaps they don’t. Wouldn’t it be more honest of the BOM to mention that? It’s not like billions of dollars depends upon it…

Seems the only time the ABC or BOM suddenly discover our historic weather records is when we get unseasonal snow or freezing cold.

Oopsie solar-battery fail? Cloud causes System Black event at Alice Springs affecting thousands

Welcome to the new complexified energy grid where a cloud can cause a system black event — knocking out power for as much as nine hours. This affected the hospital for 30 minutes and the prolonged problems caused many businesses and supermarkets to close. Alice Springs is an island microgrid servicing about 29,000 people in the centre of Australia. It was 38 degrees C yesterday when the power went out. Shame about those fridges and air conditioning units.

Alice Springs is a mini version of larger grids showing how fragile these new complicated systems of multiple generators based on weather events and batteries can be.

Yesterday: Thousands impacted by Alice Springs power blackout*

Steve Vivian, ABC News

Thousands of residents in Central Australia went without power yesterday afternoon, with some experiencing blackout conditions for up to nine hours.

Electricity was cut across the Alice Springs region around 2:30pm yesterday and was not restored in some areas until 10:47pm.

Port Hedland: one man with a keen interest knows more about this site than the Bureau of Met does

If the planet was at stake you’d think the BOM would be doing this research, not unpaid volunteers.

Bill Johnston has shown again, that the BOM is apparently unaware and, perhaps most damningly, not even interested in most of the things that happened to their official thermometer sites.

Port Hedland is supposedly “one of the best” researched sites in Australia — so it is a certified ACORN site (one of the 112). The trends matter, and being remote, it influences a large area. But one man with dedication and no funding at all can find key historical maps and photos that the BOM, with its million dollar-a-day budget, cannot. Instead of doing this hard work the BOM uses the magical homogenization process “to fix” up all the anomalies by hunting for data in sites hundreds of kilometers away that can be used to adjust the records at Port Hedland. This is the secret process that even the BOM admits it cannot describe in full to anyone outside the BOM. As Johnston says, it’s a process so bad it “should be abandoned”. There is no saving the error correction that starts with bad data, missing documents, and barely any historical research […]

Clickbait climate records: Hot in France but snowpacked in Canada and Colorado

News today is filled with “record heat” in France — whatever, it might be the hottest since thermometers started measuring, but it’s been hotter before. Even if it’s real, it’s only a technicality because we only started records recently. At most it can only be the hottest in 130 years or so, and we know it was just as hot in medieval times, hotter 7,000 years ago, hotter 130,000 years ago, and so on, hotter for most of life on Earth.

The record heat in France is a meaningless clickbait moment in climate history that preys upon the short term human psyche. Like some collective amnesia we forget that the French Revolution was but a moment ago in geologic history. So this is the worst heatwave in Europe since … 2003?

But is it even a real (albeit short term) record? We don’t know if French historic records were adjusted, cooled, subject to unaccounted site moves, or measured in super sensitive electronic thermometers that didn’t exist in 1896. But we do know that when France’s top TV meteorologists wrote a skeptical book, he was sacked. If the data is being tampered with, what are the odds that any recognised […]

ABC Climate fiction: Life at 0.5 degrees hotter, dead plants, animals, ghost towns, jellyfish hell

The job of ABC environment reporters is not to serve the public and ask scientists hard questions about whether we can rely on their climate models that fail 98% of the time and on every scale in time and locality.

Instead their job is to be fiction writers, converting failing models into vomiting babies:

Under IPCC forecasts babies born today will be 22 when warming hits 1.5C. What will life be like?

By environment reporter Nick Kilvert

Meet Casey X. She was born in Alice Springs Hospital on October 13, 2018.

She came into the world screaming, before projectile-vomiting over the hospital floor and falling asleep.

For this the ABC gets $3 million dollars every day.

We are talking about a half degree Celsius of warming spread over 22 years. This is double the decadal rate currently shown by satellites. But even if we assume that climate models are right for the first time ever, and this dramatic change in trends occurs, it’s still only half a degree more in a world where humans live from minus 50C to plus 40C and every day temperatures vary by 10 – 20 degrees.
