The Sahara may flip from desert to grass every 20,000 years. Blame The Sun.

MIT researchers think they have solved a bit of a mystery regarding Sahara dust, but if they’re right it means the Sahara Desert has already come and gone 3 – 5 times since humans walked the Earth. The Sahara is the largest desert on Earth, and this would be the largest and longest drought “ever” on the planet (as far as we know).

UPDATED: Commenter Javier points out these drying cycles were known years ago. (See below)

This would rather redefine the whole idea of “climate change” — 3.5 million square miles of Green Sahara turns into Dust-bowl Sahara — and it’s all thanks to sunlight. The drought doesn’t just last 7 years, but more like 7,000. And it’s happening over 9 million square kilometers, an area larger than Australia. The major climate models leaned towards the monsoonal cycle, rather than the longer ice age one. So this theory may have resolved one of the 495 contradictions in climate models. Or not. But the bigger message here is that the sun causes climate change and on a massive scale.

h/t to Roger Tallbloke.

The Sahara is the largest dust bowl in the world, dumping 10 million trucks of dust across North Africa and the Atlantic Ocean. The dust can end up as far away as Florida. People tracked the layers of this dust before but thought the highs and lows were driven by ice-ages on a 100,000 year cycle. This new work took a closer look at the layers on the ocean and say they see 20,000 year cycles, which fit with cycles of solar insolation (meaning the strength of sunlight as the Earth rolls around on its axis). It sounds like a long bow figuring out whether there were trees and rain in the Sahara based on layers of dirt on the ocean floor, so keep our skeptical hats on. It could turn out to be wrong. But then again, they are looking at 240,000 years of mud and it fits better with other proxies too, so it has some redeeming features.

Forget Marble Bar, Oodnadatta, doesn’t the BOM know the hottest day ever was in Albany?

It’s summer, so the BoM and ABC can’t help themselves.

Map, Albany,, Hottest Town in Australia

Albany, Hottest Town in Australia

Last week Marble Bar “hit an all time record”. This week, it’s Alice Springs. But the Australian BOM still haven’t used their own fabulous World Class ACORN Temperature data to find the hottest day ever in Australia. They’re still telling people it was in Oodnadatta, on Jan 2nd in 1960, but even dumb deniers know that according to ACORN temperatures hit 51.2C in Albany in far south WA in 1933.

[Marble Bar Dec 28th, 2018]   The high temperature occurred at 12:39 pm local time. At that stage, it appeared Marble Bar could crack 50 for the first time — and perhaps even threaten the all-time Australian record of 50.7 in Oodnadatta, South Australia.

Chris Gillham pointed this out the strange anomaly of the cool coastal town that was hotter than a million square kilometers of desert, but four years later the BOM still haven’t resolved the situation. The 51.2C temperature is still there in the data, but the Top Ten Highest Temperature Records remain exactly the same. Is Albany, or is it not, the true record holder?  Or is it that the ACORN adjustments are overwrought, unjustified fandangaling, that ignores 8 lane freeways, and brick walls and has errors so big they can be seen from space?

Bureau of Meteorology Temperature Records

Highest temperature

State Temperature (°C) Date Place name Station no. Latitude Longitude
SA 50.7 2 January 1960 Oodnadatta Airport 17043 −27.56 135.45
WA 50.5 19 February 1998 Mardie 5008 −21.19 115.98
NSW 49.7 10 January 1939 Menindee Post Office 47019 −32.39 142.42
Qld. 49.5 24 December 1972 Birdsville Police Station 38002 −25.90 139.35
Vic. 48.8 7 February 2009 Hopetoun Airport 77010 −35.72 142.36
NT 48.3 2 January 1960 Finke Post Office 15526 −25.58 134.57
48.3 1 January 1960 Finke Post Office 15526 −25.58 134.57
Tas. 42.2 30 January 2009 Scamander 92094 −41.46 148.26

These records not only ignore their own ACORN super high quality data, they also ignore measurements from Observatories too. In 1939 the Windsor Observatory recorded 122F or 50.5C. Even further back in 1909 the BOM had a Stevenson Screen at Bourke Post Office which recorded the monstrous 125F or 51.6C. But that record didn’t count because it was done on a Sunday.

The big question, (apart from why the BoM is so incompetent), is why the hottest ever days in Australia all seemed to occur back when CO2 levels were perfect. This is even after the BOM accidentally boosted all the modern temperatures by switching to electronic thermometers. These accept one-second long heatwaves that no old style thermometer could possibly detect. Not surprisingly, electronic thermometers all over the country have set new records with every gust of a 737.

Despite this huge advantage, the old temperatures are still beating out the new ones.

As for the Alice Springs record of 45.6C yesterday, I note that Alice Springs Post Office in on Jan 14 1883 recorded a whole degree hotter, 46.7C. That’s 136 years of global warming for you.

More wind and solar than SA can use — we threw away 10% of the generation

South Australians have so much wind power, too much, that in Quarter 3 last year the AEMO had to intervene to cut off excess wind and solar generation. Ever since the Great Blackout of 2016 new rules mean that there must be enough back up power running to cope with the fickle vagaries of intermittent energy.  (Obviously, this wasting of sacred green electrons wouldn’t need to happen if people weren’t so persnickety about blackouts!)

This graph is from the Quarter 3 AEMO report for 2018. It is technically about both wind and solar, but it appears to be mostly wind. Solar is not a star player in Q3 because it’s winter.

Would we put up with any other industrial output that had such a dismal performance. Imagine this was your car….

AEMO South Australia, wind energe curtailment.

AEMO Quarter 3 report page 7

Synchronous generation is the kind that comes from machines that spin at 50 Hz (like coal, gas, hydro, nukes). These keep the system stable. Happy happy hertz.

But ten percent of all the wind and solar power had to be thrown away in SA because there wasn’t enough reliable back up power to guarantee the stability of the system.

During Q3 2018, total curtailments of non-synchronous generation (large-scale wind and solar farms) in South Australia increased to around 150 GWh (or 10% of South Australian non-synchronous generation) (Figure 6), with curtailment occurring for 26% of the time during the quarter. This was the highest amount on record and around 70 GWh higher than the next highest quarter (Q3 2017). Key drivers were record high wind generation (Section 1.3.4) and insufficient synchronous generators being available to meet system strength requirements.

 The reliable generators had gone home for the day (so to speak) because they couldn’t make enough money in a screwed market where intermittent and unsynchronised electricity is preferentially subsidized. So in order to make up for the damage done by a subsidy designed to drive fossil fuels out of business, we added another subsidy to keep them running. As you would.

The extra subsidy to counter the first subsidy cost $7m that quarter.

We may have the illusion of free market competition but increasingly the government controls more and more of the industry.

Fascism is an economic system in which the government controls the private entities that own the factors of production.”  Antifa, where are you?

In 2018 Climate change caused “disastrous” loss of 0.1% of World GDP

Warning: PR Stunts Ahead.
It’s serious folks: If you use models that don’t work, extrapolate, exaggerate, and spin the runes properly, at worst, man-made climate change caused “100 billion dollars of damage” in 2018. It’s another BIN moment (a Big Irrelevant Number).

To put that in perspective, the GWP (Gross World Product) is around $100 Trillion dollars. So, all that inflated climate damage rained upon us and 99.9% of the global economy wouldn’t even notice.

Climate change-induced disasters cost nations at least $100 billion in 2018, says watchdog

News, AFP, AAP, BBC, maybe ABC, CBC, CNN, CBC, everyone with a channel.

As reported by the same people who say “If you want heart surgery, ask a doctor.”

The bill for climate-linked disasters in 2018 is estimated to be more than $100 billion according to a leading UK relief organisation.

A Relief Charity added up these numbers. They couldn’t possibly have anything to gain by inflating them, could they?

From floods to extreme heat, 10 of the worst climate-linked disasters in 2018 caused at least $A120.8 billion worth of damage, says a study released by the charity Christian Aid.

I don’t think they meant to tell us that Antarctica was fine…

Extreme weather driven by climate change hit every populated continent this year, the British relief organisation says, warning urgent action is needed to combat global warming.

“This report shows that for many people, climate change is having devastating impacts on their lives and livelihoods right now,” said Kat Kramer, who heads Christian Aid’s work on climate issues, in a statement on Thursday.

Yes, it was the strongest storm since an even stronger one hit 50 years ago:

Topping the list were hurricanes Florence and Michael, which caused an estimated $A24 billion and $A21 billion worth of damage, respectively.

Michael was the strongest storm to hit the continental United States since 1969, and killed 45 people in the US and at least 13 in Honduras, Nicaragua and El Salvador.

 In 1969 CO2 levels were 322ppm, a wonderful 80 ppm lower than today. If only we could return to that and get storms  …just like Michael.

The BBC even found some tea leaf statistics:

Research published at the time showed that the rains accompanying Hurricane Florence were made 50% worse than they would have been without human influenced warming.

But the rains could have been 50% better if they were calculated on models that worked. We’ll never know.

Notice how the “warmest years on record” have ballooned out from the “hottest single year” to the hottest five, hottest ten, now top 20:

The 20 warmest years on record have been within the past 22 years, the United Nations said last month, with 2018 on track to be the fourth hottest.

Imagine hypothetically that the last warming was cyclic. To keep using the word “hottest” PR hacks would have to create an expanding progression as the warming peaked, plateaued, then ebbed. Just sayin…

Fireman warns solar powered batteries may cause ferocious fires

House Fire

Channel Seven News.

Unintended consequences: When your insurance to stop the planet burning burns down your house instead.

Storing all that energy in a small box at home. What could possibly go wrong?

Fire crews are warning that solar powered batteries may cause fires that move fast and burn with “ferocity”.

Solar home battery warning after Brisbane house fire

Brisbane Times, Toby Crockford

The homeowner told reporters they had solar panels connected to lithium-ion batteries and suspected the fire started nearby, a view shared by firefighter Malcolm Muscat.

“[There were] approximately three battery banks so lithium-ion, lead-acid batteries, they burn with a ferocity that moves through the house quickly,” Mr Muscat said.

Remember: When the future of the planet is at stake, there’s no such thing as too much insurance.

We just hope the owners had plenty.

Friends and family can be consoled that the house has been sacrificed for a good fashionable cause.

Note this is the “suspected” cause in this fire, but solar panels have been linked to many other house fires.

Does your home need a “fire bunker”?

‘Years to understand’ fire risk of solar power systems

From July 12th, 2017, Greg Brown, The Australian

Victoria’s Metropolitan Fire Brigade has responded to more than 40 fires caused by home solar power systems in the past five years and warned that it would take years to understand the fire risk posed by lithium ion battery storage.

The MFB said the solar installations were vulnerable to faults across their systems, including isolation switches, inverters and installed wiring, and from deteriorating components.

The alarming figures come as the solar battery storage industry pushes to kill new regulations that would force homeowners to build a separate “fire bunker” housing for battery installations.

Crikey! Check out the wording on the draft safety standards:

Under draft rules released by Standards Australia, lithium ion batteries are classed as “Fire Class 1” and would not be allowed inside or within 1m of a domestic dwelling. The industry will have until August 15 to respond to the draft regulations.

Energy Safe Victoria director Neil Fraser said at least eight solar panel models had been taken off the market in the past five years because of fire concerns.

What happened to those draft AS/NZS 5139 rules from 18 months ago? After a bit of a panic from the industry and complaints Standards Australia agreed to review things, then in December last year adopted “international standards“. It’s not like we are in a fire prone country with extended fire risk seasons, large houses, and lots of solar panels, I guess…

Apparently, Standards Australia was accused of “complete overkill” for suggesting that people installing a known fire hazard should put it in a bunker.

Ben Potter, Australian Financial Review

Standards Australia could be stripped of its authority to set standards for home batteries such as the Tesla Powerwall 2 after the battery industry dismissed a draft standard requiring lithium ion batteries to be locked in concrete bunkers as “overkill”.

The standards setting body has been working on the standard for a year year but its draft standard is so onerous that battery installers reckon it could kill off their industry and German battery-maker Sonnen has shelved plans for local production until the impasse is resolved.

Imagine being accused of overkill by the same team that want to save the Earth with light globes, panels and windmills.

Merry Christmas with Carols For Coal :-)

Christmas runs on coal.

Image by pixel2013

Thanks to readers who responded to the request to respond to the  Carols against Coal. After the gripping thrill of “We Wish You a Steady Climate“, get ready for a treat.  Here’s draft one of Christmas Carols to Warm the World. Forgive the odd blasphemy, there are some absolute gems lines here. With a little more fine tuning I see lots of potential — a book for next Christmas? Thank you to the star contributors, and please keep them coming!

Merry Christmas to everyone. — Jo

Tides of Mudgee:  O Come All Ye Warmists

Oh come all ye warmists
You think you’re so triumphant
Oh come on, admit it now, you’re wrong, wrong, wrong
Climate is changing,
But we are not the cause of it.
We cannot change the CO2,
It doesn’t drive the temperature,
The biggest lie in history
Christ I’m bored.

 

Reed Coray — Jingle Coal

Burning all that coal
Warms our very soul
o’er the lumps we roll
Staying warm’s our goal.

Watching Gaia squirm
Maybe even burn
Looking for a fight
Makes our spirits bright.

Doing what we should
Even all we could
Doing plants much good
Better coal than wood

Laughing at our peers
Holding back our tears
Can’t believe our ears
Hearing phony fears.

Busy at the pole,
Elfs are mining coal
Santa’s on a roll
Leaving lumps of coal.

PeterC

Mining Coal, Mining Coal
Mining Coal all day
Oh what fun it is to load
a hopper all the way eh.

Mark M

Wind turbine, wind turbines, turbines all the way,

Oh what stupidity it is to head, back to pre-industrial days, hey!

tom0mason:  Good King Wenceslas

Old King Coal was last dug out, on the Feast of Stephen.
Wind and solar all about, rigged prices don’t breakeven.
Brightly shone the the forest that night, the fire it was cruel,
Now the poor folk roundabout hadn’t any fuel.

 

Robber:  The Twelfth day of Christmas

On the twelfth day of Christmas
My true love sent to me
Twelve greenies prattling
Eleven warmists nagging
Ten pollies raving
Nine coal mines working
Eight windmills idling
Seven panels sunning
Six rent takers reaping
Five RETs
Four subsidies
Three promises broken
Two climate cultists
And Australia up a gum tree.

Sonny: All I want for Christmas

I don’t want a lot for Christmas
There’s just one thing I need
I don’t care about the presents
and all that capitalist greed.
I just want to stop climate change
Though my friends think I’m deranged
Make my wish come true
All I want for Christmas
Is to impose my world-view.

I don’t want a lot for Christmas
There is just one thing I need
I don’t care about the presents
And would never cut down a tree
I don’t buy china made stockings
And would never light my fireplace
Santa Claus won’t make me happy
His plastic toys are a disgrace.
I just want to fight global warming
i don’t care if i am conforming
Make my wish come true
All I want for Christmas
Is to impose my world-view.

I won’t ask for much this Christmas
I won’t even wish for snow
I’m just gonna keep on waiting
For the big coal overthrow
I won’t make a list and send it
To the North Pole for Saint Nick
I would rather stay awake
and study Mann’s hockey stick.
I just want to get climate right
Thats why i won’t turn on the light
What more can i do?
Baby all I want for Christmas is
to impose my world-view.

No lights are shining
There is darkness everywhere
And the sound of children’s
Laughter vanished into thin air.
Nobody is singing
But i hear those alarm bells ringing
Santa won’t you help me with my scruple
And make Christmas Carbon Neutral.

Oh I don’t want a lot for Christmas
This is all I’m asking for
I just want to see this world
Become like Orwell’s 1984
I just want warming to slow
More than you could ever know
Make my wish come true
Baby all I want for Christmas is to impose my world-view.
Baby all I want for Christmas is to impose my world-view.
Baby all I want for Christmas is to impose my world-view.

 

 

 

 

 

Latus Dextro  — The First Noel

The First Noel
(mod. English carol, 17th century)
—————————————————————
The first Noel Mike Mann did say
Was a great warming now well underway
In committees they lay,
In politics they played,
Laying out their plans
On a hot summers day.
No-coal No-coal No-coal No-coal!
Green is the face of Gaial!
—————————————————————
They hooked up and saw a scam
Shining was the West all ’round them now,
And to the earth they gave great cash,
And so it continued both day and night.
No-coal No-coal No-coal No-coal!
Green is the face of Gaial!
—————————————————————
And by the cash from that great wealth
Wise men flew from countries afar,
To seek more cash was their intent
And to follow the wealth
Wherever it went.
No-coal No-coal No-coal No-coal!
Green is the face of Gaial!
—————————————————————
This faith grew forth to all the World
Over everything it took its cue,
And there it did both stop and stay
Over every place where power lay.
No-coal No-coal No-coal No-coal!
Green is the face of Gaial!
—————————————————————
Then did they know the great cooling seas
That their models were nix just a vacant big tease:
as the meme failed the dream did too,
And they found themselves deep in the loo:
No-coal No-coal No-coal No-coal!
Green is the face of Gaial!
—————————————————————
Then came the greater cold, the grand solar change,
that created a big chill over the world:
no food, no crops, no cash, no tax,
Gone is the greed of the carbon creed.
No-coal No-coal No-coal No-coal!
Green is the face of Gaial!
—————————————————————
Then let us all with one accord
Sing praise to all the earthly joules,
That hath made heaven
out of naught on earth,
And with warmth mankind has brought great cheer.
Noel Noel Noel Noel!
Born is the King of Israel!

 

 Alice Thermopolis: On the first day of Christmas

On the first day of Christmas,
Catholic Online sent to me
More climate fare from the Holy Chair,
And a post-truth partridge in a pear tree.

On the second day of eco-worrying,
Satan sent to me
A Polar Vortex to perplex,
And a Trump-et in a populist tree.

On the third day of extreme-weather,
An angel sent to me
A message from Jehovah, another super-Nova,
And a Paltridge in a pear tree.

On the fourth day of weird-weather,
Project Stardust sent to me
Samples from my gutter that made me splutter
But no alarmist from the IPCC.

On the fifth day of Christmas,
The American Geophysical Union sent to me
Feelings of anger, panic and fear;
Free of charge, without a fee.

On the seventh day of extreme weather,
Cool La Nina sent to me
News that El Niño’s fading fast.
The scare just couldn’t last, said she.

On the eighth day of eco-worrying,
Scott and Shackleton sent a note to me:
Little change in sea ice in a century, that’s nice;
And fifty penguins in a pear tree.

On the ninth day of Goldilocks weather,
Someone on the Hill sent a card to me;
Wow. Energy security’s the buzz-word now,
And one hundred politicians in a baobab tree.

On the tenth day of unsustainable power,
The Energy Market Operator sent a report to me:
Relax, it said, our generational mix is fine;
And one thousand windmills in a pro bono publico tree.

On the eleventh day of Christmas,
Two RMIT fellows sent a recipe to me:
Eat the roo, not the moo,
And ten thousand turkeys in a peer tree.

On the twelfth day of Christmas,
A prophecy came to me:
Curses. The alarmist circus is,
Perhaps, running out of time. We’ll see.

Sound the TRUMP-ET!

Carols singers.

A poem from Ruairi

Our carols will withstand attack,
From warmists who try to hijack,
These great Christmas tunes,
And from climate-change loons,
Who use them to hate coal and slack.

 

Eric Huxter — Imagine

Imagine there’s no fossil fuels
It’s easy if you try
Chill earth beneath us
O’er us cold blue sky
Imagine all the people
dying in their droves…

Imagine there’s no fossil fuels
It isn’t hard to do
Naught to aid survival
the CAGW religion too
Imagine all the people
dying in their droves…

You may say I’m a dreamer
But I’m not the only one
I hope someday you’ll join us
And the population will be just one

Imagine fewer humans
I wonder if you can
All is fear and hunger
A change caused by man
Imagine all the people
dying in their droves…

You may say I’m a dreamer
But I’m not the only one
I hope someday you’ll join us
And the population will be just one

New Report: Renewables indirectly make electricity MORE expensive, so ABC tells Australia the opposite

One big government agency quietly admits renewables make electricity more expensive, and another big gov media agency hides it.

The new AMEC report tells us renewables will make electricity prices go down a tiny 2% in the short run but make electricity more expensive in the long run due to forcing out cheap baseload players. What matters most to Australians — that we can expect our electricity costs to be 2% less than “obscene” for the next couple of years, or that the artificial transition we are forcing on the grid will indirectly make electricity more expensive?

Which message does the ABC headline? Say hello to Trivia!

Renewables set to drive down power prices, new AEMC analysis shows
Does ABC Fake News Make you Mad? Help expose the propaganda, donate here. Thanks. The ABC is essentially a taxpayer funded advertising machine for the renewables industry.

A flood of new renewable energy projects is likely to drive down household electricity bills, according to new analysis by government policy adviser the Australian Energy Market Commission (AEMC).

On a national basis, household bills are set to fall by 2.1 per cent — but price falls in the eastern states and South Australia are offset by increases in Western Australia, the Northern Territory and the ACT.

We pay the ABC three million dollars a day so they can parrot press releases. Unpaid bloggers only had to read to paragraph 24 to find the report says that the renewable subsidy may lead to higher wholesale prices (page V, summary, para 24). The qualification “may” applies to the renewable schemes that don’t “incentivize investment in firming technology”. In other words the “may” might as well be a “must” in Australia. There are no cheap options for “firming technology” that the RET is not actively forcing out of the market.

There’s always a way to blame coal:

The price reductions will go some way to reversing big power bill hikes driven by increased cost and market volatility driven by the retirement of two brown coal power stations — Northern at Port Augusta in SA, and Hazelwood in Victoria’s Latrobe Valley.

AMEC, Graph, electricity prices, 2018.

Look what happens when renewables increase and coal decreases…

The big picture is all a bit complicated for big-welfare-journalists. See the graph above. The carbon tax increased the price. The closure of coal plants increased the price. Renewables have increased through the whole duration of this graph and so has the price. What will make electricity cheaper … ABC says “renewables”. Sure.

In the long run, renewables increase the cost of electricity three different ways:

Firstly the subsidy itself costs money, secondly it indirectly it drives out reliable, cheap supply, then thirdly, it adds an unreliable supply that makes the other generators on the grid less efficient and higher in cost too.

The direct costs of the large-scale renewable energy target (LRET) are included in the environmental component of the cost stack. However it is important to also recognise the indirect impact of this policy.  The LRET provides incentives for increased quantities of renewable generation to enter the market, even when demand is flat or falling. This is because the revenue that these intermittent generators receive from the scheme is additional to that available.
Over time, to the extent to which the LRET contributes to the exit of thermal generation but does not incentivise investment in firming technologies, it may result in a tighter supply-demand balance and lead to higher wholesale prices. from the wholesale market and the LGC penalty price is higher than the expected long-run cost of investing in new intermittent generation.
The overall impact of the LRET has therefore been to drive down wholesale prices in the short term but, in the absence of policies and incentives to encourage investment in replacement generation and firming technologies, it contributes to periods of more volatile and potentially higher wholesale prices.   (page 44)
The AMEC committee has been saying the same thing about the LRET since 2015. (2.2 p 31 and 2.2.5 p38)

More solar rooftop PV means higher wholesale prices, not lower:

While the ABC tells Australians that renewables make electricity cheaper, the AMEC report makes it clear that more rooftop panels make electricity generation more expensive for the reliable generators on the grid.

• In the WEM in Western Australia, wholesale costs are estimated to increase throughout the reporting period. This is due to increasing gas and coal prices. Changes in the residential demand shape related to increased penetration of rooftop PV also contribute to an increase in wholesale costs. See fig 6.1

In the WEM, wholesale costs were estimated based on a Long Run Marginal Costs (LRMC) approach for the electricity system.

The LRMC approach estimated that wholesale costs are expected to increase in the WEM from 2017-18 to 2020-21 due to:

  • a slight increase in peak demand and a change in residential demand shape related to the increased penetration of rooftop PV systems. This reduces the energy demand met per fixed capital cost of generation, such that the long-run marginal costs of generation increase.
  • increasing gas and coal prices.

The direct costs of renewable energy targets

The direct costs of the Renewable Energy Target are between $50 – $250 a year and rising. But the real costs are the indirect costs. The price of wholesale electricity has tripled in the last three years. Bear in mind, these are averaged costs. Those with solar panels have much smaller electricity bills and therefore pay a lot less RET.

Sydney Hail Storm: Just how hailproof are those solar panels?

Here’s a problem coal fired plants don’t need to worry about.

Sydney’s ‘catastrophic’ hailstorm happened on Thursday, the damage bill said  to top $125 million. How much of that damage is to rooftop Solar PV? The last massive hail storm in Sydney was in 1999 — but there were hardly any solar panels then.

There are wild scenes and images everywhere.

Worst Sydney hailstorm in 20 years declared catastrophic

 At least 50,000 homes remain without power in northern Sydney and more than 1000 calls for help are waiting to be responded to by State Emergency Services after Sydney and the NSW central coast were yesterday rocked by the worst hailstorms in almost 20 years.

Before anyone yells “Climate Change”, Reader, Pat, found stories about hail the size of Eggs in Sydney in November 1929. Hail the size of Tennis Balls fell on Reids Creek near Brisbane in 1934 and hail the size of Tea Cups fell on Brookville in 1902. Paddington had “ice inches deep” on Nov 1, 1931. There are scores more Hail-the-size-of… Maybe building 2 million solar panels on a continent with hail the size of tea cups was not such a good idea?

It’ also quite difficult to tell just how bad the solar panel-related storm damage has been, but judging by the size of these hail stones, what solar panel wouldn’t break? If anyone can take photos for us that would be great.

From Twitter #SydneyStorm  See the hail smashing into the water.  Great Photography on Twitter.

Want to hurt the competition? Send in climate protestors… $91 billion cost

Opportunity costs are the most invisible costs in the world.

Purely hypothetically, if you wanted to nobble a competing country, you could pay 350.org…

“We know what it takes to stop this industry,” said 350.org’s May Boeve. “It is not a mystery, it is not magical.

Climate protests cost $91 billion in lost economic activity, chamber study finds

Climate activists fighting to derail pipelines and other energy projects have blocked $91.9 billion in U.S. economic activity and hundreds of thousands of jobs, according to a new report.

There is no Economy B. Once we have wrecked this one….

The report analyzed 15 targeted projects, including the hotly contested Keystone XL pipeline, Constitution Pipeline, and Oregon LNG terminal, as well as New York Gov. Andrew Cuomo’s 2014 fracking ban.

In addition to $91.9 billion in lost economic activity, the protests cost nearly 730,000 job opportunities and $20 billion in tax revenue to federal, state and local governments.

…, the U.S. surpassed Russia this year to become the world’s largest crude oil producer and has led the world in natural-gas production since 2009.

Deadly: a quarter of all solar panels pose high or severe risk

Got Solar PV? Don’t let the kids play on the roof

Solar Rooftop installations in Australia.

Would you like a 240Volt shock with that?

In Australia, shonky fly-by-night installers are botching the wiring and not screwing the panels on properly. As many as a quarter of solar panels pose a high or severe “electrical safety” risk. Since there are two million households with solar panels, that’s half a million homes sitting under a live problem.

By mismanagement and delusional climate-changing schemes the government has entirely and artificially created the solar bubble. Hopefully people won’t die like they did in the Pink Batts Bubble. Back then, to stop droughts and storms and save the nation from the Global Financial Crisis, the government decided to rush out home insulation. The artificial bubble brought in poorly trained workers and four people died. Kevin Rudd (former PM) now says he wouldn’t have done it if he’d known the risks. But heck, way back in 2010 no one could have realized that artificial government industry bubbles wouldn’t mix well with 240 Volts.  Sure.

Australia’s big advance seems to be to stop unnecessary deaths under roofs, and start doing them on top.

Warning of deaths over solar panel installations

  • Simon Benson, The Australian

Energy Minister Angus Taylor has written to his state counterparts to warn that lives could be at risk from unsafe or sub-standard solar panel installations, with a national audit report finding up to one-quarter of all rooftop units ­inspected posed a severe or high risk.

The national audit of the ­Renewable Energy Target has ­revealed that between 21 and 26 per cent of small-scale rooftop solar installations inspected every year since 2011 had been found to have faulty wiring and unsecured ­panels. Some posed a “severe risk” where wiring was exposed. This required units to be shut down immediately and remediated.

A total of 35 licensed installation contractors have been warned they face the possibility of suspension…

There are so many upstart sharks in the solar installation industry that the faulty panels they leave behind are known as “solar orphans”.
