Announcing BomWatch: Auditing the fake warming created by site changes near the Great Barrier Reef

Fake Warming in Queensland: The BOM says the sites didn’t move, but photos show they did.

The warming at these four sites alongside the Great Barrier Reef is due to site changes, incompetence, poor record keeping and “adjustments”. Map: Terrametrics, Map data Google 2020

All along the coast near the Great Barrier Reef, the BOM has claimed temperatures have warmed in the last 50 years, and they’ve calculated it to a tenth of a degree. To get that kind of accuracy the thermometers need to be carefully placed, and the BOM needs to know exactly where they were, but they don’t.

The BOM keeps long pages of site descriptions and exact dates of moves and equipment changes, but historic photos show the records are wrong. The BOM will solemnly swear a site was in the same place for decades but photographs and archives show the sites were often moved as developments sprang up around them. The BOM didn’t keep the records and didn’t bother to check. If the thermometer moved to a warmer location or it warmed because they replaced the standard 230-litre Stevenson screen with a 60-litre toy one, or no longer cleaned it [...]

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 [...]

What the BOM don’t say: it’s not the hottest year in Australia according to satellites

For forty years NASA satellites have been circling the Earth covering our landmass day and night. But yet again, the Australian Bureau of Meteorology has released the obligatory “hottest ever year” media release without mentioning that it wasn’t the hottest year in the far more accurate satellite record of Australia, and that this new “record” depends entirely on adjustments and quite possibly on ignoring all the data recorded in the 1800s. Once again they miss the chance to remind Australians that it was almost certainly hotter for hundreds of years seven thousand years ago. Sea levels were higher then too.

They claim it’s the driest ever year, and maybe it was, but they don’t say that there is no trend in droughts and rainfall for the last 178 years.

So to help them out I’ve graphed UAH satellite temperature record which shows that last year was the 4th hottest year since 1979 when the UAH satellite data set begins.

Perhaps in 2020 the Australian Bureau of Meteorology will set their own record, and explain for the first time how and why they adjust their data continuously and post hoc. The Australian surface data is all changed with a mystical secret [...]

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.

Excuses? Coldest Summer day, Snow in Australia and suddenly BOM remembers how inadequate their equipment is…

Coldest maximum summer temperature on record at Thredbo

Kate Doyle, ABC News

On Monday, the second day of summer, the temperature only reached -1 degrees Celsius at the Thredbo weather station, the coldest maximum temperature recorded anywhere in Australia during summer.

But really cold records don’t matter. For the first time in history, Blair Trewin, Bureau of Meteorology points out how minor these daily records are:

Blair Trewin, senior climatologist at the Bureau of Meteorology, confirmed that it was a summer as well as December record but pointed out there was more to it.

“In some ways it’s not quite as impressive as it looks,” Dr Trewin said.

This is indeed the only instance of him ever saying that.

“This is because before automatic weather stations were installed in the 1990s, manual observations at high mountain sites [like the top of Thredbo, Mount Hotham and Falls Creek] were very limited outside the ski season.”

Exactly. When will Blair Trewin tell Australians that hot records are not as impressive as they look because [...]

Whopper part II: Look what the BoM did to the last three Februarys in Australia?!

The Bureau of Meteorology did what to February?

Wow, just wow. Look what the Bureau of Meteorology has covertly done to February? Something like one third of a degree has been added to the average Australian summer maximum anomalies over the past few years according to the “expert” data from the worlds-best-practise equipment.

In the BOM Whopper Part 1 we revealed that in the BOM’s latest round of unannounced adjustments there were big increases in the rate of Australian summer warming. It turns out a lot of the summer rise comes from changes to February. Mysteriously, there were large changes to the national average of the last three years. Let that sink in.

These changes were incomprehensible because while the averaged “whole nation” got warmer, there were no changes to the data in any of the 104 individual stations.

It’s all rather spooky… but what it isn’t, is scientific.

The two main points in Bob Fernley Jones’ work:

There are big increases to measurements recorded in the last three years? Why? Yet again, the adjustments are down in the early years, up in the latter years, and overall, the rate of warming, surprise, increases thanks to man-made adjustments. He [...]
