Murray Bridge, South Australia, where thermometers record junk every day

Thanks to Bill in Oz sending in the shot of Mt Barker, Ken Stewart started auditing other sites in South Australia and discovered this masterpiece of expert siting. And thanks to Ken, you can see The Wacky World of Weather Stations: No. 2- Murray Bridge.

Year opened: 1885. Who thinks the site looked like this 130 years ago? | Image capture Mar 2018, Google ©2019

As he points out:

The screen is in a houseyard near concrete paths, vegetable gardens and shrubs, close to a picket fence, within 5 metres of sheds, sheltered from the south by a 1.6 metre high fence, with buildings to the east, north, and west, and less than 10 metres from the bitumen road.

Like Mt Barker, this is another site which is not an ACORN “top ranked” site that the Bureau of Meteorology use, but results from here are used to adjust ACORN sites like Mount Gambier, so it is de facto a part of that network. Sites like this are also used to create propaganda, sorry, press releases about “hottest ever records”.

The BoM know exactly how bad this site is, and in carefully measured detail.

Somewhere a paid bureaucrat […]

Mt Barker — How not to measure the temperature

Thanks to Bill in Oz who sent in this photo of the Mt Barker site in South Australia.

Ken Stewart at Ken’s Kingdom writes: The Wacky World of Weather Stations: No. 1- Mount Barker

Count the ways this site breaches the Bureau of Meteorology own rules:

Ken Stewart finds the relevant BoM guidelines. Clearly this site is on a slope, too close to buildings, too close to tall foliage, too close to heat sinks, it should not be artificially watered, or near asphalt. It should have a 30 meter buffer zone, and not be shielded from the sun, rain or wind. BillinOz points out that it is totally screened from the southerly cold winds, and the cold air will be drained from the spot down the slope.

How much do the Bureau of Meteorology care about climate change? — About 1m out of 30m or 3% of their advertised “care” factor. That’s a a 97% Junk-Science rate. The future of life on Earth is supposedly at stake and the “experts” can’t even be bothered accurately measuring the climate change they tell us we need to pay billions of dollars to solve.

ABC Climate Zombie Myths and Fantasy Strawmen. Who’s feeding the trolls?

Skeptics are now the brain-eating undead from Haitian Cult Voodoo. Just more namecalling in lieu of science. The ABC has become the US Weekly, TVWeek, or OK! of national policy, filled with inane clickbait animations, fictional stories and fantasy myths.

Looks like it’s projection again

Here’s a guy who believes that we control storms, floods and droughts with solar panels and wind turbines. The only climate zombie that needs hosing down is all his. He’s the one saying that the type of milk you drink, or your funeral service are to blame for random stuff like spotted quoll fertility, shark attacks, or tornadoes. Go vegan to save the planet!

Poor Nick Kilvert is so badly trained he can’t figure out why ideas like “CO2 feeds plants” just won’t die. The mystery of how the truth keeps coming back (despite their best efforts). So this weekend he put out a handy condescending guide of strawmen and mythical myths for beleaguered believers who are lost for answers to skeptical scientists. The man’s cult-like belief is so obvious, the real question we need to ask our elected MP’s is why are we funding an journalistic organization which has staff who are so incompetent, […]

Robbins Island Mega wind farm: killing birds and baseload power at 300 kilometers per hour

After nearly two weeks the ABC carrier pigeons finally brought the news that Bob Brown, former Greens leader, is campaigning against this gigantic wind farm — the $1.6b one in NW Tasmania that wants to be the largest in the Southern Hemisphere. Could it be the ABC doesn’t want to admit they were wrong too, pushing wind power non stop for years?

Look how erratic that wind is — 90% one day, zero the next

Tom Quirk looked at the nearest wind farm to Robbins Island, and it’s a fitful machine (see that graph below). Worse, it fails in synchrony with most wind farms in Australia. Thus exacerbating the unstable, fickle supply of wind energy.

Tom Quirk predicts the demise of another coal plant

Quirk was Deputy Chairman of VENCorp, which managed the transmission and wholesale natural gas market and system planning for the electricity market in Victoria, Australia.

A wind farm on Robbins Island will simply extend the variations in power supplied to the mainland while making no difference to the correlations of wind through the states in the wholesale market. Thus more backup would be required from gas and hydro sources. Loy Yang B […]

Denying 2000 years of the Medieval Warm Period, Little Ice Age on every continent

Here we go again. For five or so years believers didn’t really mention the Medieval Warm Period. Too bruised by the embarrassment of Hockey Stick Zombie failures. But it’s an inconvenient era they have to rub out because none of the expert models can explain what caused it, and it’s hard to panic about same temperatures that Edward the Confessor survived with oxen and carts.

And it’s hard to call the modern warmth “man-made” if nature created something just like it 1,000 years ago.

Climate change: We haven’t experienced anything like this in the past 2,000 years

By Michael Collett, ABC, Environmental Copy and Paste Promoter

Climate scientists writing in the journal Nature have found there is no evidence for “globally coherent warm and cold periods” over the past 2,000 years prior to industrialisation.

That’s significant, because climate change deniers have sometimes pointed to epochs like the so-called “Little Ice Age” or “Medieval Warm Period” to argue that the current global warming is one among multiple similar global climate events.

But what the research actually shows is that other “peak warming and cooling events” over the past two millennia appear to have […]

The pause in global warming shows CO2 may be *more* powerful! Say hello to Hyperwarming Wierdness.

A new Nature paper claims that pauses and cooling phases mean C02 may cause more warming than anyone thought.

Pause Excuse #431

It’s all so obvious. If researchers start with models that don’t work, they can find anything they look for — even abject nonsense which is the complete opposite of what the models predicted.

Holy Simulation! Let’s take this reasoning and run with it — in the unlikely event we actually get relentless rising temperatures, that will imply that the climate sensitivity of CO2 is lower. Can’t see that press release coming…

Nature has sunk so low these days it’s competing with The Onion.

The big problem bugging believers was that global warming paused, which no model predicted, and which remains unexplained still, despite moving goal posts, searching in data that doesn’t exist, and using error bars 17 times larger than the signal. The immutable problem is that energy shalt not be created nor destroyed, so The Pause still matters even years after it stopped pausing. The empty space still shows the models don’t understand the climate — CO2 was supposed to be heating the world, all day, everyday. Quadrillions of Joules have to go somewhere, they can’t just […]

China is warming fastest where the cities are, not where the models predicted – classic UHI

The biggest changes in temperature (“divergence” in dark red brown Fig 6) occurred where the most people lived (blue dots). In the 60 years to 2010 China was reported to have warmed by 0.79 ± 0.10 °C. However Scafetta et al calculate at most, China could have experienced a real warming of only 0.46 ± 0.13 °C.

Somehow the combined might and supercomputers at NOAA, NASA, Hadley and the Bureau of Met experts all missed this.

It’s another third of a degree gone from the Glorious CO2 Narrative. Just like that.

Fig. 6. Map of the divergence (ΔTMin − ΔTMax) between the warmings registered by the minimum and maximum temperature records (CRU TS4) between 1945 and 1954 and 2005–2014. The cyan dots indicate the 200 most populated cities in China according to the Free World City Database. (White regions over India and the ocean indicate missing data).

Is there a more perfect nation to study the Urban Heat Island effect than China?

The worlds most populous nation has made a blistering transformation in two decades. As recently as 1995 the population was 75% rural. Now it’s approaching 60% urban. Shenzhen, which is near Hong Kong, grew from 3000 people […]
