Introspection.

A recent article by George Monbiot gets me thinking.

George Monbiot is 61; his birthday is on January 27th. Thus he is 14 years younger than me. He is an experienced writer for The Guardian newspaper. Plus he has authored quite a few books and founded a charity, and given TED Talks, and I am sure more than this.

I read all of the articles that are published by him. His website is widely read. Please read his biography. Some of his many articles really get me thinking.

Some time ago I asked Mr. Monbiot for permission to republish his articles and that was granted. A small number of them have been republished on Learning from Dogs.

Today I want to republish an article that was presented on July 3rd.

The Fight Against Oligarchy

Oligarchy is the default state of politics, and it is surging back. How do we stop it?

By George Monbiot, published in the Guardian  27th June 2024

We are about to return to normal politics. After 14 years of Tory corruption and misrule, a Labour government will put this country back on track. Justice and decency will resume, public services will be rebuilt, our global standing will be restored, we will revert to a familiar state. Or so the story goes.

What is the “normal” envisaged by pundits and politicians of the left and centre? It is the most anomalous politics in the history of the world. Consciously or otherwise, they hark back to a remarkable period, roughly 1945 to 1975, in which, in certain rich nations, wealth and power were distributed, almost everyone could aspire to decent housing, wages and conditions, public services were ambitious and well-funded and a robust economic safety net prevented destitution. There had never been a period like it in the prior history of the world, and there has not been one since. Even during that period, general prosperity in the rich nations was supported by extreme exploitation, coups and violence imposed on the poor nations. We lived in a bubble, limited in time and space, in which extraordinary things happened. Yet somehow we think of it as normal.

Those “normal” politics were the result of something known to economic historians as the “great compression”: a drastic reduction in inequality caused by two world wars. In many powerful countries, a combination of the physical destruction of assets, the loss of colonial and overseas possessions, inflation, very high taxes, wage and price controls, requisitioning and nationalisation required by the wartime economy, as well as the effects of rising democracy and labour organisation, greatly reduced the income and assets of the rich. It also greatly improved, once the wars had ended, the position of the poor. For several decades, we benefited from the aftermath of these great shocks. Now the effect has faded. We are returning to true “normality”.

The history of many centuries, including our own, shows that the default state of politics is not redistribution and general welfare, but a spiral of accumulation by the very rich, the extreme exploitation of labour, the seizure of common resources and exaction of rent for their use, extortion, coercion and violence. Normal is a society in which might is right. Normal is oligarchy.

In his magisterial book The Great Leveler, published in 2017, the historian Walter Scheidel explains that only four forces have ever significantly reversed inequality: mass-mobilisation warfare (such as the two world wars), total and violent revolution, state collapse and devastating plagues. Decisions, decisions.

He shows how warfare economies were turned into welfare economies, sometimes by force. For example, following the defeat of Japan, the US occupation government, led by General Douglas MacArthur, sought what it called “the democratization of Japanese economic institutions” to ensure “a wide distribution of income and ownership of the means of production and trade”. To this end, it imposed high property taxes, with a top marginal rate of 90%; broke up business conglomerates; demanded a labour union law enabling the right to organise and strike, and higher wages for workers; organised comprehensive land reform, which dissolved large holdings and distributed them to peasants; and introduced fiscal reform that led eventually to taxes on the highest incomes of 75% and an inheritance tax on the largest estates of 70%. These programmes resulted in the near-total destruction of income from capital and the creation in Japan of a political and economic democracy, almost from scratch.

All the major combatants were similarly transformed. In the US, the top rate of estate (inheritance) tax rose to 71% in 1941, and income tax to 94% in 1944. The National War Labor Board raised workers’ pay while holding down executive pay. Union membership soared. In the UK, the top rate of income tax was held at 98% from 1941 to 1952. It took decades to decline to current levels. A purchase tax on luxury goods was introduced in 1940, with rates that later rose to 100%. The share of incomes captured by the richest 0.1% fell from 7% in 1937 to just over 1% in 1975.

In the absence of one of the four great catastrophes, income and capital inexorably accumulate in the hands of the few, and oligarchy returns. Oligarchs are people who translate their inordinate economic power into inordinate political power. They build a politics that suits them. Scheidel shows that as inequality rises, so does polarisation and political dysfunction, both of which favour the very rich, as a competent, proactive state is a threat to their interests. Dysfunction is what the Tories delivered and Donald Trump promises.

Oligarchs seek the destruction of oversight, which is why UK bodies such as the Environment Agency and the Health and Safety Executive have been comprehensively gutted. The same desire was the driving force behind Brexit. They want the cessation of protest. They want a failing NHS, to justify privatisation. They want malleable politiciansand a tame BBC. They get what they want, distorting every aspect of national life. They pour money into neoliberal and far-right political movements, which help capital to solve its perennial problem: democracy. The arc of history bends towards injustice. But every so often it is broken over the knee of catastrophe.

If you want a return to the rich nations’ “normality” of 1945 to 1975 – in other words, to redistribution, a shared sense of national purpose, robust public services and a strong economic safety net, high employment and good wages – and I think most people would, you need a politics that is not just abnormal, but unprecedented. Snapping the arc of injustice would mean going way beyond Jeremy Corbyn’s 2019 manifesto, let alone Keir Starmer’s limp offering, which treads so carefully around the interests of the rich. We would need to do what the world wars did, without the violence and physical destruction: a peacetime MacArthur programme for overthrowing the oligarchs.

Political parties would need to overcome their fear of economic power: of the newspaper barons, the property developers, the fossil fuel companies, hedge funds, private equity bosses and assorted oligarchs who now fund and influence our politics. The longer we leave this confrontation, the more extreme and entrenched oligarchic power becomes. If we want even a modicum of democracy, equality, fairness and a functioning state, we need not the accommodation with economic power that Starmer seeks, but the mother of all battles with it.

ooOOoo

Let me repeat a sentence from the article: “Oligarchs are people who translate their inordinate economic power into inordinate political power.”

I am towards the end of my life. Whether or not things will change politically, as Monbiot suggests above, I do not know. But if asked to guess I would say probably not.

I would love to see a different, as in a better way, of us humans running things. I can’t put it better than how George Monbiot expressed it in that last sentence: “If we want even a modicum of democracy, equality, fairness and a functioning state, we need not the accommodation with economic power that Starmer seeks, but the mother of all battles with it.”

Finally, George Monbiot has a saying on his website: “I love not man the less, but Nature more.” I wish that were not the case, I wish oligarchy was a dead word, but Nature is so beautiful.

Independence Day

July 4th, 2024

From WikiPedia (in part):

Independence Day, known colloquially as the Fourth of July, is a federal holiday in the United States commemorating the Declaration of Independence, which was ratified by the Second Continental Congress on July 4, 1776, establishing the United States of America.

The Founding Father delegates of the Second Continental Congress declared that the Thirteen Colonies were no longer subject (and subordinate) to the monarch of Britain, King George III, and were now united, free, and independent states.[1] The Congress voted to approve independence by passing the Lee Resolution on July 2 and adopted the Declaration of Independence two days later, on July 4.

A post on Heat

Not the first and I’m sure it won’t be the last on this topic!

We are experiencing the first week of Summer’s heat.

Where it is going, temperature-wise, who knows but the consensus is that it is becoming warmer year on year.

So this seemed like a great post to republish. It was on The Conversation.

Heat index warnings can save lives on dangerously hot days − if people understand what they mean

You’ve probably heard people say, “It’s not the heat, it’s the humidity.” There’s a lot of truth to that phrase, and it’s important to understand it as summer temperatures rise.

Humidity doesn’t just make you feel sticky and uncomfortable – it also creates extra dangerous conditions on hot days. Together, too much heat and humidity can make you sick. And in severe cases, it can cause your body to shut down.

Meteorologists talk about the risk of heat and humidity using the heat index, but it can be confusing.

I’m a risk communication researcher. Here’s what you need to know about the heat index and some better ways meteorologists can talk about the risks of extreme heat.

What is the heat index, and how is it measured?

Heat index is the combination of the actual air temperature and relative humidity:

  • Air temperature is how hot or cold the air is, which depends on factors such as the time of day, season of the year and local weather conditions. It is what your thermometer reads in degrees Celsius or Fahrenheit.
  • Relative humidity compares how much water vapor is in the air with how much water vapor the air could hold at that temperature. It’s expressed as a percentage.

The heat index tells you what it “feels like” outside when you factor in the humidity. For example, if it’s 98 degrees Fahrenheit (36.7 Celsius) with 55% relative humidity, it might feel more like a scorching 117 F (47.2 C).

A chart with a grid showing heat and humidity risks.
NOAA’s heat index chart shows how heat and humidity combine for dangerous temperatures. NOAA

But there’s a catch: Heat index is measured in shady conditions to prevent the sun’s angle from affecting its calculation. This means if you’re in direct sunlight, it will feel even hotter.

Apparent temperature, alerts and wet bulb

“Apparent temperature” is another term you might hear this summer.

Apparent temperature is the “feels like” temperature. It considers not only temperature and humidity but also wind speed. This means it can tell us both the heat index and wind chill – or the combination of the temperature and wind speed. When conditions are humid, it feels hotter, and when it’s windy, it feels colder.

We found that apparent temperature is even less well understood than the heat index, possibly due to the word apparent having various interpretations.

There are a few other ways you may hear meteorologists talk about heat.

Wet bulb globe temperature considers temperature, humidity, wind and sunlight. It’s especially useful for those who spend time outdoors, such as workers and athletes, because it reflects conditions in direct sunlight.

HeatRisk is a new tool developed by the National Weather Service that uses colors and numbers to indicate heat risks for various groups. More research is needed, however, to know whether this type of information helps people make decisions.

In many places, the National Weather Service also issues alerts such as excessive heat watches, warnings and advisories.

The risk is getting lost in translation

Knowing about heat and humidity is important, but my colleagues and I have found that the term heat index is not well understood.

We recently conducted 16 focus groups across the United States, including areas with dry heat, like Phoenix, and more humid areas, like Houston. Many of the people involved didn’t know what the heat index was. Some confused it with the actual air temperature. Most also didn’t understand what the alerts meant, how serious they were or when they should protect themselves.

In our discussions with these groups, we found that meteorologists could get across the risk more clearly if, instead of using terms like heat index, they focus on explaining what it feels like outside and why those conditions are dangerous.

Watches, warnings and advisories could be improved by telling people what temperatures to expect, when and steps they can take to stay safe.

Climate change is exacerbating heat risks by making extreme heat more common, intense and long-lasting. This means clear communication is necessary to help people understand their risk and how they can protect themselves.

What you can do to protect yourself

With both hot and humid conditions, extra precautions are necessary to protect your health. When you get hot, you sweat. When sweat evaporates, this helps the body cool down. But humidity prevents the sweat from evaporating. If sweat cannot evaporate, the body has trouble lowering or regulating its temperature.

Although everyone is at risk of health issues in high heat, people over 65, pregnant women, infants and young children can have trouble cooling their bodies down or may run a higher risk of becoming dehydrated. Certain health conditions or medications can also increase a person’s risk of heat-related illness, so it’s important to talk to your doctor about your risk.

Heat illnesses, such as heat exhaustion and heat stroke, are preventable if you take the right steps. The U.S. Centers for Disease Control and Prevention focuses on staying cool, hydrated and informed.

  • Stay cool: Use air conditioning in your home, or spend time in air-conditioned spaces, such as a shopping mall or public library. Limit or reschedule your exercise and other outdoor plans that occur in the middle of the day when it is hottest.
  • Stay hydrated: Drink more water than you might otherwise, even if you don’t feel thirsty, so your body can regulate its temperature by sweating. But avoid sugary drinks, caffeine or drinks with alcohol, because these can cause you to become dehydrated.
  • Stay informed: Know the signs of heat illness and symptoms that can occur, such as dizziness, weakness, thirst, heavy sweating and nausea. Know what to do and when to get help, because heat illnesses can be deadly.
Heat exaustion includes dizziness, thirst, heavy sweating, nausea and weakness. Move to cooler area, loosen clothing, sip cool water and get medical help if no improvement. If heat stroke, including confusion, dizziness and unconsciousness, also call 911.

That last diagram on staying cool, staying hydrated, and staying informed is one element in me choosing this article for publication. Further, if one looks up the website for the Centers for Disease Control and Prevention then immediately one comes across:

Stay cool indoors.Stay in an air-conditioned place as much as possible. If your home does not have air conditioning, go to the shopping mall or public library—even a few hours spent in air conditioning can help your body stay cooler when you go back into the heat.

Please take care!

This D-Day

80 years since that very important day!

And another day where things got in the way and I didn’t write a proper post.

The Same Language, but …

We are so close yet in some ways so separate!

George Bernard Shaw once quoted that: “England and America are two countries separated by the same language.”

It seems a most apt way of introducing an article published by The Conversation.

UK and US elections: 2 very different systems united by a common political language

Garret Martin, American University School of International Service

Voters in the United Kingdom on May 22 learned the date they would be joining the many, many people casting ballots around the world in 2024.

In a surprise move, Prime Minister Rishi Sunak announced a snap election to be held on July 4 – six months earlier than many had expected. An early election is certainly a major gamble for the prime minister but one he felt was worth taking. With the ruling Conservative Party more than 20 percentage points behind opposition Labour in the latest polls, Sunak faces an uphill battle to stay in office.

The Labour Party, led by Keir Starmer, is heavily favored to return to power for the first time since 2010.

To a U.S. audience, many of the top issues in the election campaign will sound familiar: the economy, immigration, health care, Ukraine and Gaza. The choice of date, too, may ring a bell – and political soothsayers are already trying to read into what it means for the U.K. election to fall on Independence Day.

But as to the campaign itself – well, they do things a bit different on the other side of the pond. While Americans may be used to set terms and lengthy campaigns filled with endless advertising, in the U.K. such things are, to use a Britishism, “just not cricket.” Here are three main ways in which the British conduct their elections.

1. Election timeline

U.S. elections follow a predictable schedule. In 1845, Congress passed a law establishing a single day for federal elections to take place on “the Tuesday next after the first Monday in November.” Further, presidents are elected for a fixed four-year term, making the dates for upcoming votes knowable for the foreseeable future.

That isn’t the case in the United Kingdom. By convention, elections have been held on a Thursday since 1935. But the month of the vote has varied considerably. For the most part, they take place in late spring or early summer – but fall and winter elections are not unheard of.

The U.K. Parliament does have a fixed term of five years, with elections automatically scheduled once that time has lapsed. In practice, however, parliaments have rarely gone the full five years.

Indeed, prime ministers in the United Kingdom have the authority to request the dissolution of Parliament at any time. They can do so without the approval of the cabinet, and so prime ministers have taken liberal advantage of their ability to control the timing of the election to try and gain an advantage.

Many thought that Sunak may have been eyeing an election later in the year, but a number of factors, including economic forecasts and not wanting the distraction of a U.S. election, may have factored in to him calling an earlier-than-expected vote.

2. Campaign rules

Besides the shifting timing, the nature and rules of the campaign are also very different in the United Kingdom. This starts with the sheer brevity of the campaign. Once Parliament is dissolved, the election must take place 25 working days later. This means the parties have a mere six weeks to make their case to the public.

And unlike in a presidential system, voters in the United Kingdom do not cast a ballot for the person they want to see lead the country. Instead, the U.K. is divided into 650 distinct constituencies; voters pick their preferred candidate to represent their local constituency in Parliament. The party with the most seats typically wins the election, and the leader of that party has the opportunity to become prime minister and govern as a single-party government or as part of a coalition.

U.K. election campaigns are also subject to strict rules to maintain neutrality. Once the campaign starts, the period of “purdah” kicks in, which imposes certain restrictions on government activities. This involves, for instance, strict prohibitions on government ministers announcing new initiatives to affect the election or using public funds for political purposes.

In the same manner, civil servants – employees of the crown who work for the government but are not political appointees – are required to maintain strict impartiality and not become involved in partisan debates.

Moreover, the Office of Communications, the United Kingdom’s independent media regulatory authority, also enforces strict rules for broadcast media, including television and radio. The 2003 Communications Act requires that all broadcast media must cover the elections in an impartial manner, providing coverage of all parties, even if they do not assign equal time.

Broadcast media is also not allowed, on polling day, to suggest the outcome of the vote before polls are closed.

In a huge departure from the U.S., U.K. political parties are banned from buying television ads, but this rule does not apply to streaming television.

3. The role of money

The limited role of money is another distinct feature in U.K. elections. Even factoring in the different population sizes, U.K. elections are significantly cheaper than their counterparts in the United States.

Indeed, total campaign spending in the 2020 U.S. elections, covering presidential and congressional races, hit more than US$14 billion. That scale completely dwarfs how much parties and candidates will be able to spend in the 2024 United Kingdom election.

Through regulations established by the Electoral Commission, an independent government agency, a British party that competes in all constituencies in the United Kingdom will be allowed to spend just over £34 million (around $43 million) in total to support all candidates.

That figure in itself marks an 80% increase from the allowance at the last election in 2019, so to factor for inflation since limits were set in 2000.

Individual candidates can spend funds to support their campaign. But the amount, defined partly by the size of the constituency, is low and in the scale of tens of thousands of pounds. This is again a far cry from some of the more expensive congressional races in the United States, where even primary elections could attract close to $30 million in spending.

Challenging times ahead

As a result, both Sunak and Starmer will have only a short time – and limited funds – to make their case to voters. Whoever wins will face a very challenging situation at home and abroad, with little to no respite. According to the think tank Institute for Fiscal Studies, the state of public finances is “a dark cloud that hangs over the election.” And then there is the delicate matter of maintaining a special relationship with the U.S. – a country that may itself have a very different political landscape after it goes to the polls later in the year.

As I have frequently said, I feel English and love the fact that I speak with an English accent. Yet I adore, along with Jean, where we live just outside Merlin in Southern Oregon. I wouldn’t want to live anywhere else in the world.

The Quantum Field Theory

This is on the edge of my understanding!

Patrice Ayme recently posted an essay called Relativistic Length Contraction Busts Helium3! As I said in my comment to that post:

“This is far ahead of my knowledge of science. I applaud you for writing this despite me not understanding it”

So it may seem a little strange that I now publish the following. It was published originally on Skeptic. It is quite a long video but, please, settle down and watch it.

Sean Carroll is creating a profoundly new approach to sharing physics with a broad audience, one that goes beyond analogies to show how physicists really think. He cuts to the bare mathematical essence of our most profound theories, explaining every step in a uniquely accessible way.

Quantum field theory is how modern physics describes nature at its most profound level. Starting with the basics of quantum mechanics itself, Sean Carroll explains measurement and entanglement before explaining how the world is really made of fields. You will finally understand why matter is solid, why there is antimatter, where the sizes of atoms come from, and why the predictions of quantum field theory are so spectacularly successful. Fundamental ideas like spin, symmetry, Feynman diagrams, and the Higgs mechanism are explained for real, not just through amusing stories. Beyond Newton, beyond Einstein, and all the intuitive notions that have guided homo sapiens for millennia, this book is a journey to a once unimaginable truth about what our universe is.

Sean Carroll is Homewood Professor of Natural Philosophy at Johns Hopkins University, and Fractal Faculty at the Santa Fe Institute. He is host of the Mindscape podcast, and author of From Eternity to Here, The Particle at the End of the Universe, The Big Picture, and Something Deeply Hidden. He has been awarded prizes and fellowships by the National Science Foundation, NASA, the American Institute of Physics, the Royal Society of London, and many others. He lives in Baltimore with his wife, writer Jennifer Ouellette. His new book series, The Biggest Ideas in the Universe, includes one volume on Space, Time, and Motion, and this new volume on Quanta and Fields.

Those solar flares

Plenty of news stories to choose from.

A massive solar storm is expected to hit Earth, possibly impacting our communication grids.

NOAA presented a report for May 12th that said:

EVENT:
A coronal mass ejection (CME) is an eruption of solar material. When they arrive at Earth, a geomagnetic storm can result. Watches at this level are very rare.
TIMING:
Several CMEs are anticipated to merge and arrive at Earth on May 12th.
EFFECTS:
The general public should visit our webpage to keep properly informed. The aurora mav become
visible over much of the northern half of the country, and maybe as far south as Alabama to
northern California.

Meanwhile, Earth.com presented the following (and it is a long but extremely interesting report):

Update: New solar flare, secondary peak today in this “Extreme” solar storm

By Eric Ralls, Earth.com staff writer

Update — May 12, 2024 at 8:04 PM EDT

The Sun released another powerful burst of energy today, known as a solar flare, reaching its peak intensity at 12:26 p.m. Eastern Time. The flare originated from a region on the Sun’s surface called sunspot Region 3664, which has been quite active lately.

NASA’s Solar Dynamics Observatory, a spacecraft that keeps a constant eye on our nearest star, was able to capture a striking image of this latest solar outburst.

Solar flares are immense explosions on the Sun that send energy, light and high speed particles into space. They occur when the magnetic fields in and around the Sun reconnect, releasing huge amounts of stored magnetic energy. Flares are our solar system’s most powerful explosive events.

The NOAA’s Space Weather Prediction Center (SWPC) has extended the Geomagnetic Storm Warning until the afternoon of May 13, 2024.

Understanding different classes of solar flares

Today’s flare was classified as an X1.0 flare. Solar flares are categorized into classes based on their strength, with X-class flares being the most intense. The number provides additional information about the flare’s strength within that class. An X1 flare is ten times more powerful than an M1 flare.

These energetic solar eruptions can significantly impact Earth’s upper atmosphere and near-Earth space environment. Strong flares can disrupt high-frequency radio communications and GPS navigation signals. The particle radiation and X-rays from flares can also pose potential risks to astronauts in space.

Additionally, the magnetic disturbances from flares, if particularly strong, have the ability to affect electric power grids on Earth, sometimes causing long-lasting blackouts.

However, power grid problems are more commonly caused by coronal mass ejections (CMEs), another type of powerful solar eruption often associated with strong flares.

Scientists are always on alert, monitoring the Sun for these explosive events so that any potential impacts can be anticipated and prepared for. NASA’s Solar Dynamics Observatory, along with several other spacecraft, help provide this early warning system.

Stay tuned to Earth.com and the Space Weather Prediction Center (SWPC) for updates.

Update — May 12, 2024 at 9:41 AM EDT

The ongoing geomagnetic storm is expected to intensify later today, Sunday, May 12, 2024. Several intense Coronal Mass Ejections (CMEs), traveling from the Sun at speeds up to 1,200 miles per second, are anticipated to reach the Earth’s outer atmosphere by late afternoon.

Over the past two days, preliminary reports have surfaced regarding power grid irregularities, degradation of high-frequency communications, GPS outages, and satellite navigation issues. These disruptions are likely to persist as the geomagnetic storm strengthens.

Auroras visible across the continental United States

Weather permitting, auroras will be visible again tonight over most of the continental United States. This spectacular display of lights is a direct result of the ongoing geomagnetic storm.

The threat of additional strong solar flares and CMEs, which ultimately result in spectacular aurora displays, will persist until the large and magnetically complex sunspot cluster, NOAA Region 3664, rotates out of view of the Earth. This is expected to occur by Tuesday, May 14, 2024.

Solar activity remains at moderate to high levels

Solar activity has been at moderate levels over the past 24 hours. Region 3664 produced an M8.8/2b flare, the strongest of the period, on May 11 at 15:25 UTC. A CME signature was observed, but an Earth-directed component is not suspected.

Solar activity is expected to remain at high levels from May 12-14, with M-class and X-class flares anticipated, primarily due to the flare potential of Region 3664.

Energetic particle flux and solar wind enhancements

The greater than 10 MeV proton flux reached minor to moderate storm levels on May 10. Additional proton enhancements are likely on May 13-14 due to the flare potential and location of Region 3664.

The solar wind environment has been strongly enhanced due to continued CME activity. Solar wind speeds reached a peak of around 620 miles/second on May 12 at 00:55 UTC. 

A strongly enhanced solar wind environment and continued CME influences are expected to persist on May 12-13, and begin to wane by May 14.

Geomagnetic field reaches G4 “Severe” storm levels

The geomagnetic field reached G4 (Severe) geomagnetic storm levels in the past 24 hours due to continued CME activity. 

Periods of G3 (Strong) geomagnetic storms are likely, with isolated G4 levels possible, on May 12. Periods of G1-G3 (Minor-Strong) storming are likely on May 13, and periods of G1 (Minor) storms are likely on May 14.

Stay informed and enjoy the light show

As the geomagnetic storm rages on, we must remain vigilant and prepared for the potential consequences. Monitor official sources for updates on the storm’s progress and any further disruptions to our technological infrastructure. 

Take a moment to step outside tonight and marvel at the incredible auroras painting the night sky — a stunning reminder of the raw power and beauty of our Sun.

While these solar storms can cause temporary inconveniences, they also provide us with an opportunity to reflect on our place in the universe and the awe-inspiring forces that shape our world.

Stay tuned to Earth.com and the Space Weather Prediction Center (SWPC) for updates.

Understanding geomagnetic solar storms

Geomagnetic storms are disturbances in the Earth’s magnetic field caused by the interaction between the solar wind and the planet’s magnetosphere. These storms can have significant impacts on technology, infrastructure, and even human health.

Causes of geomagnetic storms

Geomagnetic storms typically originate from the Sun. They are caused by two main phenomena:

  • Coronal Mass Ejections (CMEs): Massive bursts of plasma and magnetic fields ejected from the Sun’s surface.
  • Solar Flares: Intense eruptions of electromagnetic radiation from the Sun’s surface.

When these events occur, they send charged particles streaming towards Earth at high speeds, which can take anywhere from one to five days to reach our planet.

Effects on Earth’s magnetic field

As the charged particles from CMEs and solar flares reach Earth, they interact with the planet’s magnetic field. This interaction causes the magnetic field lines to become distorted and compressed, leading to fluctuations in the strength and direction of the magnetic field.

Impacts on technology and infrastructure

Geomagnetic storms can have significant impacts on various aspects of modern technology and infrastructure:

  • Power Grids: Strong geomagnetic storms can induce currents in power lines, causing transformers to overheat and potentially leading to widespread power outages.
  • Satellite Communications: Charged particles can damage satellite electronics and disrupt communication signals.
  • GPS and Navigation Systems: Geomagnetic disturbances can interfere with the accuracy of GPS and other navigation systems.
  • Radio Communications: Storms can disrupt radio signals, affecting communication systems that rely on HF, VHF, and UHF bands.

Aurora Foundation

One of the most visually striking effects of geomagnetic storms is the formation of auroras, also known as the Northern and Southern Lights.

As charged particles collide with Earth’s upper atmosphere, they excite oxygen and nitrogen atoms, causing them to emit light in various colors.

Monitoring and forecasting

Scientists continuously monitor the Sun’s activity and use various instruments to detect and measure CMEs and solar flares.

This data helps them forecast the timing and intensity of geomagnetic storms, allowing for better preparedness and mitigation of potential impacts.

Historical geomagnetic storms

Some of the most notable geomagnetic storms in history include:

  • The Carrington Event (1859): The most powerful geomagnetic storm on record, which caused widespread telegraph system failures and auroras visible as far south as the Caribbean.
  • The Halloween Storms (2003): A series of powerful geomagnetic storms that caused power outages in Sweden and damaged transformers in South Africa.
  • The Quebec Blackout (1989): A geomagnetic storm that caused a massive power outage affecting millions of people in Quebec, Canada.

Understanding geomagnetic storms is crucial for protecting our technology-dependent world and mitigating the potential risks associated with these powerful space weather events.

Stonehenge

A fascinating account of this English site.

Although I was born in London in 1944, as a result of an affair between my father and mother, my father had two daughters with his wife, Maud, and Rhona and Corinne, for they were their names, took me under their wing. In the 50s Maud, Rhona and Corinne all moved to Devon and I started going regularly to Totnes. When I started driving I usually stopped for a break close by Stonehenge so the site has a special interest to me.

So when I saw this article in The Conversation it had to be shared.

Stonehenge may have aligned with the Moon as well as the Sun

When it comes to its connection to the sky, Stonehenge is best known for its solar alignments. Every midsummer’s night tens of thousands of people gather at Stonehenge to celebrate and witness the rising Sun in alignment with the Heel stone standing outside of the circle. Six months later a smaller crowd congregates around the Heel stone to witness the midwinter Sun setting within the stone circle.

But a hypothesis has been around for 60 years that part of Stonehenge also aligns with moonrise and moonset at what is called a major lunar standstill. Although a correlation between the layout of certain stones and the major lunar standstill has been known about for several decades, no one has systematically observed and recorded the phenomenon at Stonehenge.

This is what we are aiming to do in a project bringing together archaeologists, astronomers and photographers from English Heritage, Oxford, Leicester and Bournemouth universities as well as the Royal Astronomical Society.

There is now an abundance of archaeological evidence that indicates the solar alignment was part of the architectural design of Stonehenge. Around 2500 BC, the people who put up the large stones and dug an avenue into the chalk seemed to want to cement the solstice axis into the architecture of Stonehenge.

Archaeological evidence from nearby Durrington Walls, the place where scientists believe the ancient people who visited Stonehenge stayed, indicates that of the two solstices it was the midwinter one that drew the largest crowd.

But Stonehenge includes other elements, such as 56 pits arranged in a circle, an earthwork bank and ditch, and other smaller features such as the four station stones. These are four sarsen stones, a form of silicified sandstone common in Wiltshire, that were carefully placed to form an almost exact rectangle encompassing the stone circle.

Only two of these stones are still there, and they pale in comparison to their larger counterparts as they are only a few feet high. So what could their purpose be?

Lunar standstill

The rectangle that they form is not just any rectangle. The shorter sides are parallel to the main axis of the stone circle and this may be a clue as to their purpose. The longer sides of the rectangle skirt the outside of the stone circle.

It is these longer sides that are thought to align with the major lunar standstill. If you marked the position of moonrise (or set) over the course of a month you would see that it moves between two points on the horizon. These southern and northern limits of moonrise (or set) change on a cycle of 18.6 years between a minimum and a maximum range – the so-called minor and major lunar standstills, respectively.

The major lunar standstill is a period of about one and a half to two years when the northernmost and southernmost moonrises (or sets) are furthest apart. When this happens the Moon rises (and sets) outside the range of sunrises and sets, which may have imbued this celestial phenomenon with meaning and significance.

The strongest evidence we have for people marking the major lunar standstill comes from the US southwest. The Great House of Chimney Rock, a multi-level complex built by the ancestral Pueblo people in the San Juan National Forest, Colorado, more than 1,000 years ago.

It lies on a ridge that ends at a natural formation of twin rock pillars – an area that has cultural significance to more than 26 native American tribal nations. From the vantage point of the Great House, the Sun will never rise in the gap between the pillars.

However, during a major standstill the Moon does rise between them in awe-inspiring fashion. Excavations unearthed preserved wood that meant researchers could date to the year episodes of construction of the Great House.

Of six cutting dates, four correspond to major lunar standstill years between the years AD1018 and AD1093, indicating that the site was renewed, maintained or expanded on consecutive major standstills.

Returning to southern England, archaeologists think there is a connection between the major lunar standstill and the earliest construction phase of Stonehenge (3000-2500 BC), before the sarsen stones were brought in.

Several sets of cremated human remains from this phase of construction were found in the southeastern part of the monument in the general direction of the southernmost major standstill moonrise, where three timber posts were also set into the bank. It is possible that there was an early connection between the site of Stonehenge and the Moon, which was later emphasised when the station stone rectangle was built.

The major lunar standstill hypothesis, however, raises more questions than it answers. We don’t know if the lunar alignments of the station stones were symbolic or whether people were meant to observe the Moon through them. Neither do we know which phases of the Moon would be more dramatic to witness.

A search for answers

In our upcoming work, we will be trying to answer the questions the major lunar standstill hypothesis raises. It’s unclear whether the Moon would have been strong enough to cast shadows and how they would have interacted with the other stones. We will also need to check whether the alignments can still be seen today or if they are blocked by woods, traffic and other features.

The Moon will align with the station stone rectangle twice a month from about February 2024 to November 2025, giving us plenty of opportunities to observe this phenomenon in different seasons and phases of the Moon.

To bring our research to life, English Heritage will livestream the southernmost Moonrise in June 2024, and host a series of events throughout the year, including talks, a pop-up planetarium, stargazing and storytelling sessions.

Across the Atlantic, our partners at the US Forest Service are developing educational materials about the major lunar standstill at Chimney Rock National Monument. This collaboration will result in events showcasing and debating the lunar alignments at both Stonehenge and at Chimney Rock.

Well I learnt something from this, which just goes to show that we are never too old to learn.

To come back to the article, the skills of those ancient peoples were just awe-inspiring.
