Concorde – Die gefallene Göttin

von Hans Hofmann-Reinecke

Woodstock und Apollo

Es gab einmal eine Zeit, da war alles anders – nichts war unmöglich. Auf den Wiesen von Woodstock scharten sich eine halbe Million Fans um Joan Baez und Jimi Hendrix und lauschten ihrer Musik. Statt Maske hatten sie einen Joint dabei und insgesamt zwölf Polizisten waren genug, um für Ordnung zu sorgen; und man landete auf dem Mond; und zum ersten Mal flog damals die Concorde, die Außerirdische unter den Airlinern, zu der selbst die coolsten Briten mit Bewunderung aufschauten, wenn Sie über ihren Köpfen schwebte.

Concorde war mehr als ein modernes Flugzeug, sie war ein Kunstwerk. Wie eine Skulptur von Michelangelo öffnete sie dem Betrachter eine Sekunde lang den Einblick in eine Dimension, die sonst verschlossen war. Ihre Magie lag in der Form der Flügel, die einmal mehr die alte Pilotenweisheit bestätigte: was gut fliegt sieht auch gut aus. Und die Concorde konnte verdammt gut fliegen.

Jenseits der Schallmauer

Sie war jenseits der Schallmauer unterwegs und in der Stratosphäre. In einer Welt, die bisher „Top Guns“ mit Sauerstoffmaske und Helm in engen Cockpits vorbehalten war, konnte man jetzt bei Champagner und Kaviar Smalltalk halten. Während Jumbo & Co. in zwölf Kilometern Höhe mit 900 km/h vor sich hin trödeln – das ist auch Mach 0,85, also 85% der Schallgeschwindigkeit – flog die Concorde mit Mach 2, d.h. 2100 km/h in 18 Kilometern Höhe. Für die Strecke London – New York brauchte sie nur drei, statt bisher sieben Stunden.

Mit einem herkömmlichen Airliner hatte die Concorde auch sonst wenig gemeinsam. Am deutlichsten wurde das an den Tragflächen, deren Aufgabe es ist, den Flieger in der Luft zu halten. Der Auftrieb, den sie bieten, hängt von Größe und Form ab, aber auch von der Geschwindigkeit und dem Winkel gegen die Flugrichtung, dem Anstellwinkel.

Das mit der Geschwindigkeit ist ein Problem, denn man möchte ja, dass der Auftrieb genau das Gewicht des Fliegers ausgleicht, egal wie schnell man unterwegs ist, und am Himmel will man schnell sein, während man unten am Boden lieber langsam ist. Ein Jumbo soll ja nicht mit Mach 0,8 starten oder landen, sondern eher mit 250 km/h.

Wie also kann die gleiche Tragfläche das gleiche Gewicht sowohl bei 900 km/h als auch bei 250 km/h, tragen?

Die Nase hoch

Als aufmerksamer Passagier werden Sie mir jetzt widersprechen: es ist ja nicht die gleiche Tragfläche, denn während des Anflugs zur Landung tauchen an Vorder- und Hinterkante der Flügel alle möglichen Klappen auf, die jetzt zusätzlich für Auftrieb sorgen, die aber unterwegs im Flügel versteckt sind. Und diese Landeklappen sorgen dafür, dass der Jumbo noch getragen wird, auch wenn er schon ganz langsam ist.

Genauso ist es. Aber was soll man machen, wenn die Tragflächen für den Überschallflug ganz dünn sein müssen, so dass kein Platz für Klappen da ist? Da kann man den Anstellwinkel bei Start und Landung ja ganz groß machen, da muss der Flieger nur die Nase hoch genug in die Luft heben. Das geht aber nur bis zu einem bestimmten Punkt, dann „reißt die Strömung ab“, die Luft fließt nicht mehr glatt über die Fläche und der Auftrieb verschwindet.

In typischen Airlinern ist bei einem Winkel von 15 Grad Schluß. Für die Concorde aber überlegten sich schlaue Köpfe – ohne Computer – eine ganz außergewöhnliche Form, die noch bis 40 Grad Auftrieb liefert. Das machte Klappen überflüssig und führte zur ikonischen Silhouette des Flugzeugs. Sie streckte bei Start und Landung die Nase ganz weit nach oben, und damit die Piloten dann noch vorwärts sehen konnten, wurde die Spitze der Nase heruntergeklappt.

Sie brauchte aber trotzdem noch 400 km/h zur Starten, in der Luft war sie dann fünfmal so schnell. Und sie landete mit nur 300 km/h, was damit zu hatte, dass sie jetzt nur halb so schwer war wie beim Abflug, weil knapp hundert Tonnen Treibstoff unterwegs verbraucht wurden.

Schall und Rauch

Es wurden zwanzig Exemplare von diesem Wunderwerk gebaut, die für Air France und British Airways zwischen 1976 und 2003 im Linienverkehr unterwegs waren, aber auch für Charters eingesetzt wurden. Man konnte aber nicht beliebige Routen fliegen, denn der „Überschall Knall“ würde Bewohner der überflogenen Regionen belästigen.

So wie die Bugwelle eines Dampfers auf dem Badesee ans Ufer schwappt und die Sonnenanbeterinnen von ihren Handtüchern aufscheucht, so erzeugt ein Objekt, das schneller als 1200 km/h fliegt, eine Bugwelle aus Luft, die am Boden als Knall registriert wird. Der Flieger macht nicht nur in dem Moment Krach, in dem er „durch die Schallmauer bricht“, er zieht den Knall wie eine Schleppe nach sich, so lange er mehr als Mach eins hat.

In dem Video kann man das nicht nur hören, sondern sogar sehen, denn in der „Bugwelle“ kühlt sich die Luft ab, sodass die Feuchtigkeit kondensiert und sich ein weißes Röckchen aus Dunst um den Flugzeugrumpf bildet.

Die Belästigung durch den Knall sorgte für berechtigte und unberechtigte Proteste, sodass die Concorde schließlich nur auf Routen über Wasser eingesetzt wurde, und hier hauptsächlich von London oder Paris an die amerikanische Ostküste. Zu der Zeit keimte aber schon ideologischer Widerstand gegen erfolgreiche neue Technologien auf, und Concorde hatte ständig gegen Bedenkenträger anzukämpfen.

Natürlich war Concorde weder ökologisch noch ökonomisch, aber welches Kunstwerk ist das schon. Das Taj Mahal war auch nicht umsonst.

Der Flug Air France 4590

Insgesamt fanden von 1976 bis 2000 Zigtausende problemloser Flüge statt und der Name Concorde stand nicht nur für Eleganz, sondern auch für Zuverlässigkeit. Das änderte sich ganz dramatisch vor 20 Jahren, als am 25. Juli 2000 eine Concorde der Air France beim Start verunglückte. Dabei kamen alle 105 Personen an Bord ums Leben, und es gab weitere vier Opfer an der Absturzstelle. Was war die Ursache des Unglücks?

Es gibt unterschiedliche Sichtweisen. Das Ergebnis der Untersuchung durch die französischen Behörden sieht die Ursache in einem Metallstreifen, den eine zuvor gestartete DC10 der Continental Airlines auf der Bahn verloren hatte. Über diesen rollte die Concorde kurz vor dem Abheben. Der Reifen wurde dabei zerfetzt und ein Fragment wurde von unten gegen die linke Tragfläche geschleudert. Die Wucht war so groß, dass der Tank im inneren platzte und Treibstoff ausströmte, der sich entzündete. Die Maschine konnte noch abheben, aber das Feuer machte sie unkontrollierbar und es kam zum Absturz.

Analyse eines Profis

Ob es wirklich so war? Die Meinung eines langjährigen britischen Concorde-Kapitäns, der sich intensiv mit der Sache beschäftigt hat, ist hier wiedergegeben . Seine Ansicht: Das linke Fahrwerk, bestehend aus vier, im Rechteck angeordneten Rädern, war kurz zuvor gewartet worden. Beim Zusammenbau war nachweislich ein Teil vergessen worden, was dazu führte, dass eines der vier Räder keine Führung hatte und aus der Fahrtrichtung ausscherte, „wie die Rollen an einem Einkaufswagen das manchmal tun“ . Dadurch entstand Reibung und der Reifen erhitzte sich.

Die Bremswirkung des linken Fahrgestells hatte jetzt zur Folge, dass der Pilot das Flugzeug nicht mehr auf der Bahn halten konnte, es driftete unaufhaltsam zur Seite und steuerte auf eine Boeing 747 zu, die links von der Startbahn wartete, um diese anschließend zu überqueren. Um nicht zu kollidieren zog er die Maschine, die eigentlich noch zu langsam war, in die Luft und flog nur wenige Meter über den Jumbo, in dem, neben anderen, der französische Präsident Jacques Chirac saß.

Die Überhitzung des Rades oder auch der erwähnte Metallstreifen führten dann zur Explosion des Reifens und zur Beschädigung des Tanks. Die Schleppe von brennendem Treibstoff, die das Flugzeug jetzt hinter sich schleifte, löste im Cockpit Feueralarm aus, auf den hin der Flugingenieur eines der vier Triebwerke abschaltete – ohne den Kapitän zu fragen! Das Flugzeug, ohnehin zu langsam und zu schwer, hatte sich schon vorher kaum in der Luft halten können. Jetzt aber, mit nur noch drei Motoren, war alle Hoffnung verloren und es kam zum Absturz.

La Gloire de la France

Welche Version entspricht der Wahrheit? Man kann annehmen, dass die offizielle französische Darstellung nicht nur auf technischer Analyse beruhte, sondern stark juristisch und politisch gefärbt war. Man tat alles, um den Ruf der Airline Frankreichs und ihre aeronautische Kompetenz nicht zu schädigen. Man wich dazu einer Reihe von sehr peinlichen Fragen aus.

Wie konnte so eine kritische Panne bei der Inspektion eines Fahrwerks passieren? Gab es da keine Qualitätskontrolle? Wie konnte es sein, dass der Kapitän, der Starpilot von Air France, so viele eklatante handwerkliche Fehler auf einmal machte? Das Gewicht des Flugzeugs war über dem Limit, der Schwerpunkt war zu weit hinten und er startete mit dem Wind, statt dagegen. Und warum wusste der Flugingenieur nicht, was er bei Feueralarm zu tun hatte?

Durch die offizielle Untersuchung aber wurde die ganze Aufmerksamkeit auf einen banalen Metallstreifen gelenkt, den ein amerikanisches Flugzeug verloren hatte. Der allein war an der Katastrophe schuld. Warum nicht? Es war ja auch nur ein Zigarettenstummel, der Notre Dame in Brand setzte.

Titanic der Lüfte

Was auch immer die Ursache war, die Aura dieses einmaligen Flugzeugs war von einem Tag auf den anderen erloschen. Es war eine Götterdämmerung für den technischen Fortschritt. Die geflügelte Göttin des Sieges war gestürzt. Das Ereignis war vergleichbar mit dem Verlust der Titanic 1912, der das Ende einer goldenen Ära einläutete. Welches Zeitalter läutete der Crash der Concorde ein?

Das ist kein Geheimnis; wir erleben es ja jeden Tag.

ExxonMobil “Cancelled” by The Wall Street Journal… Dumped From DJIA

Guest “WTF?” by David Middleton

A couple of days ago Charles forwarded me a reader request for commentary on the recent decision to dump ExxonMobil from the Dow Jones Industrial Average. The reader specifically mentioned me, possibly because I’ve been a geophysicist/geologist in the oil & gas industry since 1981.

I replied that it’ll either be a very brief, “This sucks!” Or a longer diatribe about the idiocy of ESG “investing”… I was preparing to go the latter route, particularly after Charles forwarded me a peer-reviewed paper, outlining the idiocy of ESG “investing”… Then I decided that the best way to ridicule The Wall Street Journal was to simply explain what they did.

First: A Few Questions Answered

WTF is ESG “Investing”?

What Are Environmental, Social, and Governance (ESG) Criteria?

Environmental, social and governance (ESG) criteria are a set of standards for a company’s operations that socially conscious investors use to screen potential investments. Environmental criteria consider how a company performs as a steward of nature. Social criteria examine how it manages relationships with employees, suppliers, customers, and the communities where it operates. Governance deals with a company’s leadership, executive pay, auditsinternal controls, and shareholder rights.

Investopedia

ESG “investing” is virtue signalling with your own money… Or, virtue signalling with OPM (other people’s money) that you manage (See Larry Fink & Blackrock).

What is the Dow Jones Industrial Average?

What Is the Dow Jones Industrial Average (DJIA)?

The Dow Jones Industrial Average (DJIA), also known as the Dow 30, is a stock market index that tracks 30 large, publicly-owned blue chip companies trading on the New York Stock Exchange (NYSE) and the NASDAQ. The Dow Jones is named after Charles Dow, who created the index back in 1896 along with his business partner Edward Jones.1 When reporters on television networks say the phrase “The market is up today,” they are generally referring to the Dow.

The DJIA is the second oldest U.S. market index; it is second to the Dow Jones Transportation Average.1 The DJIA was designed to serve as a proxy for the health of the broader U.S. economy.

[…]

When the index initially launched in 1896, it included only 12 companies. Those companies were primarily part of the industrial sector,1 including companies in the railroad, cotton, gas, sugar, tobacco, and oil industry and was in fact a spin-off of the Dow Jones Transportation Average, making the DJIA the second oldest stock market index in the United States. In the early 20th century, the performance of industrial companies was typically tied to the overall growth rate in the economy. As a result, the relationship between the Dow’s performance and that of the economy was cemented. Even today, for many investors a strong-performing Dow equals a strong economy (while a weak-performing Dow likely indicates a slowing economy).

As the economy changes over time, so does the composition of the index. The Dow typically makes changes when a company becomes less relevant to the current trends of the economy, or when a broader economic shift occurs and a change in the composition of the index needs to be made to reflect it.

[…]

Investopedia

The DJIA is based on stock prices rather than market capitalization. So, stock splits tend to force lineup changes.

The DJIA was supposed to be representative of the industrial sector of the US economy. This is why it used to be referred to as the “30 industrials.” There was a time when The Nightly Business Report would report on all of the indices (industrials, utilities, transportation).

Who decides what companies make up the DJIA?

Today, the DJIA is a benchmark that tracks American stocks that are considered to be the leaders of the economy and are on the Nasdaq and NYSE. The DJIA covers 30 large-cap companies, which are subjectively picked by the editors of The Wall Street Journal.

Over the years, companies in the index have been changed to ensure the index stays current in its measure of the U.S. economy. In fact, none of the initial companies included in the average remain, with General Electric holding the longest tenure, 110 years.

Investopedia

The people who decide what news gets published decide which companies are on the DJIA,

What did The Wall Street Journal Do?

Gratuitous pop culture reference

They basically traded Babe Ruth to the New York Yankees in order to fund a Broadway musical production.

George Herman “Babe” Ruth

In all, Ruth had played six seasons with the Red Sox, leading them to three World Series victories. On the mound, Ruth pitched a total of 29 2/3 scoreless World Series innings, setting a new league record that would stand for 43 years. He was fresh off a sensational 1919 season, having broken the major league home run record with 29 and led the American League with 114 runs-batted-in and 103 runs. In addition to playing more than 100 games in left field, he also went 9-5 as a pitcher. With his prodigious hitting, pitching and fielding skills, Ruth had surpassed the great Ty Cobb as baseball’s biggest attraction.

Despite Ruth’s performance, the Red Sox stumbled to a 66-71 record in 1919, finishing at sixth place in the American League. New ownership took control of the club, and in early January, owner Harry Frazee made the decision to sell Ruth to the Yankees for $125,000 in cash and some $300,000 in loans (which Frazee reportedly used to finance his Broadway production interests).

[…]

The deal paid off–in spades–for New York, as Ruth went on to smash his own home run record in 1920, hitting 54 home runs. He connected for 59 homers in 1921, dominating the game and increasing Yankee revenues to the point that the team was able to leave the Polo Grounds (shared with the New York Giants baseball team) and build Yankee Stadium, which opened in 1923 and became known as “the house that Ruth built.” Throughout the rest of the 20th century, the legacy of Frazee’s lopsided trade continued to hover over major league baseball, as the Yankees won 39 AL pennants and 26 World Series titles and the Red Sox went 86 years without a World Series win. In 2004, the Sox finally shook the “Curse of the Bambino,” coming from behind to beat the Yankees in the AL Championship and beating the St. Louis Cardinals to win their first Series since 1918.

History.com

What actually happened?

Apple recently announced a four for one stock split. This effectively reduced the tech sector’s representation on the DJIA, necessitating the replacement of some industrial companies with tech companies.

Apple’s 4-1 stock split, will reduce the DJIA’s tech representation, as a result, the team at S&P Dow Jones Indices announced late Monday, noting the new members will help “offset that reduction” and better reflect modern industries.

Fox Business

In one of the worst trades in DJIA history, Pfizer (a company that actually makes things) was traded for AmGen (a biotechnology company), Raytheon (a company that helps keep us free) was swapped for Honeywell (I think they make air filters and thermostats) and ExxonMobil (produces the energy that is needed to do everything) was effectively traded for a player to be named later (Salesforce ???).

What does Salesforce do?

Company Description

salesforce.com, inc. engages in the design and development of cloud-based enterprise software for customer relationship management. Its solutions include sales force automation, customer service and support, marketing automation, digital commerce, community management, collaboration, industry-specific solutions, and salesforce platform. The firm also provides guidance, support, training, and advisory services. The company was founded by Marc Russell Benioff, Parker Harris, David Moellenhoff, and Frank Dominguez in February 1999 and is headquartered in San Francisco, CA.

Marketwatch

Allow me to rephrase the question: WTF is Salesforce? That was as helpful as reading the plot synopsis of The Matrix. At this point, I’m getting a 1999 déjà vu feeling… all over again.

This move left Chevron as the only oil company in the DJIA.

Why pick Chevron over ExxonMobil?

ExxonMobil (XOM) had been a component of the DJIA for 98 years, going back to when it was Standard Oil of New Jersey. From 1999-2008, ExxonMobil was the only oil company in the DJIA. Chevron, which was dropped in 1999 and added back in in 2008, will now be the only oil company in the DJIA. 1999 was the height of the dot.com bubble… A bubble that began to burst in 2000. At the time, we used to joke that if we announced that instead of drilling actual oil & gas wells, we would drill virtual oil & gas wells, our stock price would go through the roof… And the DJIA is all about stock price. This is why Chevron stays in, and ExxonMobil gets the boot.

ExxonMobil vs Chevron vs “The Energy Sector.” Motley Fool

Chevron has arguably been more fiscally disciplined than ExxonMobil since the 2014-2016 crash. Although, if not for Occidental breaking up Chevron’s acquisition of Anadarko Petroleum last year, things would be different. Chevron was set to acquire Anadarko for $33 billion last year, when Occidental made a $38 billion offer to Anadarko. Chevron refused to increase its offer and received a $1 billion break-up fee. Occidental paid a premium for Anadarko about a year before oil prices crashed. Chevron’s initial offer to Anadarko would have been cash flow positive within 1 year at $65/bbl. Chevron clearly won by losing. Chevron was then able to acquire Noble Energy at a discount after oil prices crashed in a deal that will be cash flow positive at current prices.

Predictably, CNN had a whacked out take on this…

Exxon was the world’s largest company in 2013. Now it’s being kicked out of the Dow

By Matt EganCNN Business

[…]

Exxon’s Tesla problem

Yet even if Guyana turns out to be a win for Exxon, the company faces an uphill battle because of the climate crisis.Exxon is the best-known company in the fossil fuels industry at a time when investors would prefer to bet on solar, wind and Tesla (TSLA).Although European oil companies including BP (BP) and Total (TOT) have aggressively invested on renewable energy and set bold emissions targets, Exxon’s efforts have been far more muted.”It’s a PR problem for energy companies,” said Ben Cook, portfolio manager at Hennessey BP Energy Fund. “You can either part of the solution or be seen as part of the problem.”

[…]

CNN Business

Note to Matt: There is no “climate crisis”… Even if there was a “climate crisis,” Chevron would be facing the same “uphill battle.”

So… If The Wall Street Journal editors needed to keep one oil company in the DJIA, Chevron was probably the right choice… But… NOT “because of the climate crisis.”

What does Babe Ruth have to do with this?

By now, I’m hoping that a tech-savvy commentator has already explained to me what it is that Salesforce actually does… Because this really is looking like trading Babe Ruth to fund a stage production of No,No, Nanette.

ExxonMobil closed at $39.94 on Monday. The current quarterly dividend is $0.87/share (a nearly 9% yield). Salesforce closed at $272.65 and pays no dividend. Let’s look at what the DJIA is supposed to be again:

The Dow Jones Industrial Average (DJIA), also known as the Dow 30, is a stock market index that tracks 30 large, publicly-owned blue chip companies trading on the New York Stock Exchange (NYSE) and the NASDAQ.

Investopedia

What does “blue chip” mean?

What Is a Blue Chip?

A blue chip is a nationally recognized, well-established, and financially sound company. Blue chips generally sell high-quality, widely accepted products and services. Blue chip companies are known to weather downturns and operate profitably in the face of adverse economic conditions, which helps to contribute to their long record of stable and reliable growth.

Investopedia

Granted, ExxonMobil’s (XOM) stock price has taken a beating since it was the largest company in the world in 2013; while Salesforce’s (CRM) stock price is booming (or bubbling)… But the stock price doesn’t really tell you much about the actual businesses.

XOM Income and Cash Flow vs CRM Income and Cash Flow

Income/Cash Flow ExxonMobil  Salesforce 
2019 (billions) XOM  CRM XOM/CRM
Sales Revenue $              256.00 $          13.2819.3
Gross Income $                54.92 $            8.866.2
Pre-tax Income $                20.06 $            0.9820.4

Net Operating Cash Flow $                29.72 $            3.408.7
Free Cash Flow $                   5.36 $            2.801.9

XOM Profitability vs CRM Profitability

Return on Total Capital4.821.7            2.84
Return on Invested Capital6.590.43          15.33

ExxonMobil clobbers Salesforce in every income, cash flow and profitability metric except “gross margin” and “free cash flow.” Salesforce’s gross margin is about three times that of ExxonMobil because it apparently doesn’t cost very much to make whatever is made in the “cloud.” However, ExxonMobil’s operating, pretax and net margins are all much higher than Salesforce. This is due to Salesforce having a much higher SG&A expense (63% of revenue) than ExxonMobil (5% of revenue).

What Is Selling, General & Administrative Expense (SG&A)?

Selling, general and administrative expense (SG&A) is reported on the income statement as the sum of all direct and indirect selling expenses and all general and administrative expenses (G&A) of a company. SG&A, also known as SGA, includes all the costs not directly tied to making a product or performing a service. That is, SG&A includes the costs to sell and deliver products and services and the costs to manage the company.  

Investopedia

In the oil & gas industry, companies with high SG&A’s are generally considered poorly managed.

ExxonMobil’s operating cash flow is about 9 times that of Salesforce, but their free cash flow is only twice as large. My guess is that whatever Salesforce pays its people to make in the “cloud” doesn’t require much capital. Free cash flow can be simplistically defined as operating cash flow minus capital expenditures. If ExxonMobil drilled wells in the cloud instead of the Earth, they could practically eliminate capital expenditures.

XOM Valuation vs CRM Valuation

Basically, lower valuations indicate that a company’s stock price is under-valued and higher valuations indicate that a company’s stock price is over-valued.

XOM Efficiency vs CRM Efficiency

Efficiency XOM  CRM XOM/CRM
Revenue/Employee $        3,417,824 $     348,939            9.79
Income Per Employee $            191,455 $          2,571          74.47
Receivables Turnover                      9.912.96            3.35
Total Asset Turnover                      0.720.4            1.80

When it comes to the bottom line, the typical ExxonMobil employee is about 75 times as productive as the typical Salesforce employee… Maybe Salesforce is into renewable energy?

What NPR Misses About Energy Jobs In America

To make a long story, short

ExxonMobil was dumped from the DJIA… Because climate change… Because Apple’s four for one stock split.

Mining For Renewables Threatens Biodiversity, Scientists Warn

Mining for renewable energy materials could threaten biodiversity, researchers have found. 

Scientists at the University of Queensland, Brisbane found a high degree of overlap between areas used for mining essential minerals like lithium, which is used for car batteries, and areas with high levels of biodiversity as yet untouched by industry.

Conservationists are “often naive to the threats posed by significant growth in renewable energies”, the researchers said in the study published in the journal Nature Communications, pointing out that 14 per cent of protected areas contain metal mines or have them nearby. 

Overall, the researchers found that eight per cent of mining areas were within range of areas designated as protected by national governments, and seven per cent were within the same range of key biodiversity areas.

Using this metric, 50 million square kilometres of the earth’s land surface are influenced by mining, with 82 per cent of mining areas focused on elements needed for renewable energy production.

Elements including lithium, cobalt and nickel are essential for rechargeable batteries, which are used for power storage in wind and solar projects, as well as in electric cars.

New mines are planned targeting these substances, adding to the global surface area covered by mining activities. 

“Increasing the extent and density of mining areas will obviously cause additional threats to biodiversity, and our analysis reveals that a greater proportion of mines targeting materials for renewable energy production may further exacerbate threats to biodiversity in some areas,” the scientists wrote.

EXTINCTION REBELLION TO CAUSE MORE DISRUPTION

This piece looks at the sinister activities of Extinction Rebellion who are making a bid to take control of the country. Even if they had a good reason for doing so this would still be undemocratic and no elected government should give in to these anarchists. The fact is that they are a dangerous minority who would have no chance of winning an election, so should have no say in the running of our country.

Our democracy has never been under greater threat in recent times than it is now from protest groups who act by disrupting our lives with violent, aggressive behaviour. It is time our police showed some mettle and disrupted them.

Point-by-point rebuttal of Kamala Harris’s unscientific climate tweet

By Paul Homewood

Joe Bastardi takes apart Kamala Harris’ climate claims:

image

Honestly, sometime I marvel at things like this.

It’s like shooting fish in a barrel.

Point by point rebuttal of Kamala Harris outrageous tweet

Outrageous statements such as this are gifts that keeps on giving.

Let’s check the facts:

1) wildfires less than 20% of earlier 20th century in acreage burned.

2) Hurricane ace index/storm near record lows this year, Globally no increase. EPAC/WPAC well below average So is total Global production this season.

3) Much worse storms than what we see now have always run rampant. The list is legion and too numerous to name.

4) Heatwaves are nothing compared to the 1930s , and if you didn’t have rolling blackouts due to energy policy, there would be less problems, Why the rest of the nation would want to adopt the example of California is beyond any rational person. Besides cold kills more than warm, another fact ignored.

Obviously the person making this statement either does not know these facts, or does and simply seeks to hide them to push a false missive. There can be no other conclusion.

Apparently Kamala Harris does not understand that previous times as warm as today were known as climate optimums, not climate emergencies. We can go on and on, but in this case brevity makes the point

Hunterston B to close two years early

By Paul Homewood

This one sneaked under the radar last week:

image

Hunterston B nuclear power station in Ayrshire is to close almost two years early after cracks were found in the core of its reactors.

Regulators have given permission for reactor three to resume operations for a further six months despite more than 350 cracks in the graphite bricks.

Owner EDF Energy said it would seek authority for a second six-month run.

The company told BBC Scotland there would be 125 job losses when power generation ends.

The process of decommissioning will begin no later than January 2022. The reactor was due to continue operation until 2023.

https://www.bbc.co.uk/news/uk-scotland-glasgow-west-53935708

Hunterston is one of a number of nuclear plants due to close in the next few years, most of which have already had extra life squeezed out of them:

The GFS has been hinting at a potentially historic blast of Arctic cold engulfing the lower-48 beginning Mon, Sept 7 for a while now; and the model has just doubled-down on that forecast.

Latest GFS runs suggest next week could begin with a shiver and a shudder as temperature departures across the majority of the U.S. sink 8C to 18CBELOW the seasonal average.

This could be historic.

Just look at that frigid streak of pink (below) clipping Wyoming, Colorado, New Mexico, Texas, Arkansas, and Kentucky; and completely engulfing Kansas, Oklahoma, Missouri, Illinois, and Indiana:

And again, note how well this pattern matches with temp departures during the Maunder Minimum (the last full-blown Grand Solar Minimum)–and not only in the CONUS and Canada, but also in Alaska and the southern tip of Greenland, too:

Next week’s Arctic blast is set to shift a little south on Wednesday:

And will persist Thursday through Sunday, before temperatures closer to the seasonal average prevail for most on Monday.

Wrap-up America.

Summer Snow ALREADY Clipping the Mountain States

Record cold has already been suffered in the west of late, with heavy summer snow settling across the mountain states.

The cold front brought freezing temps and summer snow to Wyoming.

The state’s Department of Transportation web cams along WYO 22 over Teton Pass show snow falling Monday afternoon:


Colorado’s highest elevations saw the first snow of the season on Saturday, and more has fallen since. In addition, CBS4 Denver reports that a few Coloradans have also reported snow high up on Trail Ridge Road as well.


And finally, the flakes began flying on the final day of August, with the mountains of western Montana seeing healthy accumulations for the time of year:

In addition to the snow, the National Weather Service issued a hazardous weather alert for freezing conditions on Sunday night into Monday.

The COLD TIMES are returning, the mid-latitudes are REFREEZING; in line with historically low solar activitycloud-nucleating Cosmic Rays, and a meridional jet stream flow.

Even NASA appears to agree, if you read between the lines, with their forecast for this upcoming solar cycle (25) seeing it as “the weakest of the past 200 years,” with the agency correlating previous solar shutdowns to prolonged periods of global cooling here.


Prepare for the COLD— learn the facts, relocate if need be, and grow your own.
