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 […]

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 […]

EPA Part 2: How many degrees Celsius of warming will these new WA Guidelines abate?

Time for the cost-benefit question. In a sane world, the business case for carbon mitigation is like a naked singularity. No matter how many times the question is asked, no numerical answer ever emerges.

Yet whole economies are circling around this very question. — Jo

—————————————————————————-

Question 2: How many degrees Celsius of warming will these new requirements abate, and how will this outcome be measured?

What are the benefits to the Western Australian environment from the EPA recommendations, especially given that almost no nation is trying to reduce emissions and installing as much renewable energy as rapidly as Australia already is.[1]

The WA population is 2.6 million or about 0.03% of the total population of Earth. Given that the largest economies in the world, such as China, India, Brazil, Japan and Indonesia are not going to achieve significant emissions reductions, the imposition on the people of WA poses a large burden on the industry and economy of the state which may be entirely pointless. Only 16 countries are even aiming to meet their Paris targets.[2] One of those 16 is Indonesia, but only five months ago Indonesia threatened to withdraw from Paris Agreement.[3] The United States of America […]

EPA Part 1: Has the EPA done due diligence on the IPCC Climate Report? (Has anyone?)

The WA Environmental Protection Authority (EPA) wants every new project to aim for carbon neutrality, costing billions, almost certainly increasing pollution overseas, but hoping to lower temperatures over WA by 2100 AD.

The EPA is a scientific advisory body — the government doesn’t have to follow their advice — but if it does, and the advice was wrong — who is responsible for loss and damages which are foreseeable? The IPCC favoured models do not include solar magnetic, spectral or particle-flow parameters, and repeatedly fail. They are unaudited, unvalidated, and unaccountable. If the sun controls the climate these models will not show that. If the EPA is not doing due diligence on reports of a foreign committee, which person representing Western Australians is?

Rare: Sudden Stratospheric Warming in the Southern Hemisphere — cold weather coming?

Right now a very rare southern SSW (Sudden Stratospheric Warming) is taking place, possibly peaking today or this weekend over Antarctica. In the Northern Hemisphere SSW’s happen more often and in the month afterwards, wild polar blasts like the “Beast from the East” can peel off. So somewhere way up at 10hPa or 30 – 50 km, there is an area that’s warmed from -60C to close to zero. The warming up high throws a spanner in the normal jet streams and weeks later, down at the surface, blobs of cold air from the poles may end up wandering far from “home”.

We (as in Africa, Australia, Argentina, or New Zealand) may get bumper snow and severe frosts, or we may not. Some researchers are getting excited and are using the word “historic”.

These are rare over the Southern Hemisphere — due to Antarctica being shaped like a circular cheesecake right over the pole and surrounded by water. The geography is cleaner and simpler than at the north pole, and that generates a strong circumpolar jetstream. The strong pattern normally stops these sudden warmings up high which occur with wandering jetstreams.

In the Southern Hemisphere there have only […]

History keeps getting colder — ACORN2 raises Australia’s warming rate by over 20%

More warming adjustments from ACORN2

Once again we find that the oldest thermometers were apparently reading artificially high even though many were newish in 1910 and placed in approved Stevenson screens.) This is also despite the additional urban warming effect of a population that grew 400% since then. What are the odds?!

Fortunately, gifted craftsmen, sorry scientists have uncovered the true readings from the old biased thermometers which they explain carefully in a 67 page impenetrable document.

Chris Gillham has soldiered through the new “ACORN 2” adjustments that the Australian Bureau of Meteorology has o-so-quietly released and Australians are just waking up to find that our coldest mornings back in 1910 were even colder than anyone realized at the time. Graham Lloyd is reporting in The Australian how the second rewrite in six years increases the warming by 23% . (Where was the ABC announcement?)

The ACORN series of the Bureau of Meteorology includes 112 stations. Their report lists the warming trends per decade in Table 9. I converted that into the total warming since 1910 and graphed that below.

About one third of the warming of our mean temperature is due to man-made adjustments

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 […]

The biggest unnoticed storms in the world cause sudden Polar Vortex havoc

Sudden Stratospheric Warmings

Who knew? The polar vortices are the two strongest and largest “storms” on the planet. These continent scale storms are 600 miles across with winds raging at 300km per hour. Simon Clark is doing (or has done) a PhD in polar vortexes. He describes how each winter they form high over the poles. These are stratospheric, circling far above jet streams and planes. The tight circular pattern keeps the coldest air corralled. But every now again, the neat circle falls apart. In the polar stratosphere sometimes temperatures warm in days by stupid amounts, like 50 degrees C. It’s called a Sudden Stratospheric Warming (SSW) and one started around Christmas time.

As Clark describes it, these are easily the most violent weather events on the planet. (They sound fascinating). As with unbalanced centrifuges, when things unravel, as the high speed system unravels, the arctic cold could spin off anywhere — this week it’s the US, but Europe and Russia are often targets too. There is a lag involved — after an SSW it may take two weeks for things to hit the fan on the surface, so to speak. Generally, when an SSW hits it presages a […]

Forgotten history: 50 degrees everywhere, right across Australia in the 1800s

Don’t believe your lying eyes — Australian newspaper archives are full of temperatures recorded higher than 121 in the shade which is 50C. All of these temperatures in the map below are found in historic newspaper archives. Measurements done after 1910 are even done with official Stevenson screens, yet the BOM “throws them away”. It’s true that ones done in the 1800s are often recorded on non-standard equipment, or are just literally “in the shade” under cover. So some of these, perhaps many, are one or two degrees too high. But even if we take two degrees off, how scary is global warming when Australia knew many days of 48C and 49C and some at 50C 120 years ago? The BOM — supposedly so concerned about the State of Our Climate — show little interest in talking about our history or in analyzing it, or even mentioning it.

And modern temperatures are recorded on electronic equipment, sometimes in areas affected by urban heat islands (concrete and cars).

Far Southern Ocean cools. Kiss Goodbye to polar amplication around Antarctica

A map of the sea surface zone that has cooled since 1979 — from 56S – 72S . It’s a pretty big area. Click to enlarge.

For years the IPCC have said that warming would be amplified at the poles. They warned us things would heat up twice as fast, which would melt sea ice. The oceans surface in turn would switch from being reflective white to a dark absorbing deep blue. Enormous amounts of energy would then flow into the ocean instead of being reflected back out to space. The more it warmed, the more it would warm — unleashing a devastating feedback loop.

As the Arctic warmed, the merchants of doom were keen to tell us how how right they were and this was evidence of man-made warming. But in the Antarctic exactly the opposite trend was taking place.

Mike Jonas has done what the IPCC should have been doing — investigating the trends in the Sea Surface Temperature in the polar latitudes with satellite records. In the latitude band from 56 to 72 degrees south the oceans have cooled, not warmed. The models don’t even have the sign of the trend correct. At the latitudes where […]
