Space storm alert: 90 seconds from catastrophe - by Michael Brooks

IT IS midnight on 22 September 2012 and the skies above Manhattan are filled with a flickering curtain of colorful light. Few New Yorkers have seen the aurora this far south but their fascination is short-lived. Within a few seconds, electric bulbs dim and flicker, then become unusually bright for a fleeting moment. Then all the lights in the state go out. Within 90 seconds, the entire eastern half of the US is without power.

A year later and millions of Americans are dead and the nation's infrastructure lies in tatters. The World Bank declares America a developing nation. Europe, Scandinavia, China and Japan are also struggling to recover from the same fateful event - a violent storm, 150 million kilometres away on the surface of the sun.

It sounds ridiculous. Surely the sun couldn't create so profound a disaster on Earth. Yet an extraordinary report funded by NASA and issued by the US National Academy of Sciences (NAS) in January this year claims it could do just that.

Over the last few decades, western civilizations have busily sown the seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from the surface of the sun could wipe out our power grids, with catastrophic consequences.

The projections of just how catastrophic make chilling reading. "We're moving closer and closer to the edge of a possible disaster," says Daniel Baker, a space weather expert based at the University of Colorado in Boulder, and chair of the NAS committee responsible for the report.

It is hard to conceive of the sun wiping out a large amount of our hard-earned progress. Nevertheless, it is possible. The surface of the sun is a roiling mass of plasma - charged high-energy particles - some of which escape the surface and travel through space as the solar wind. From time to time, that wind carries a billion-tonne glob of plasma, a fireball known as a coronal mass ejection. If one should hit the Earth's magnetic shield, the result could be truly devastating.

The incursion of the plasma into our atmosphere causes rapid changes in the configuration of Earth's magnetic field which, in turn, induce currents in the long wires of the power grids. The grids were not built to handle this sort of direct current electricity. The greatest danger is at the step-up and step-down transformers used to convert power from its transport voltage to domestically useful voltage. The increased DC current creates strong magnetic fields that saturate a transformer's magnetic core. The result is runaway current in the transformer's copper wiring, which rapidly heats up and melts. This is exactly what happened in the Canadian province of Quebec in March 1989, and six million people spent 9 hours without electricity. But things could get much, much worse than that.

Worse than Katrina

The most serious space weather event in history happened in 1859. It is known as the Carrington event, after the British amateur astronomer Richard Carrington, who was the first to note its cause: "two patches of intensely bright and white light" emanating from a large group of sunspots. The Carrington event comprised eight days of severe space weather.

There were eyewitness accounts of stunning auroras, even at equatorial latitudes. The world's telegraph networks experienced severe disruptions, and Victorian magnetometers were driven off the scale.

Though a solar outburst could conceivably be more powerful, "we haven't found an example of anything worse than a Carrington event", says James Green, head of NASA's planetary division and an expert on the events of 1859. "From a scientific perspective, that would be the one that we'd want to survive." However, the prognosis from the NAS analysis is that, thanks to our technological prowess, many of us may not.

There are two problems to face. The first is the modern electricity grid, which is designed to operate at ever higher voltages over ever larger areas. Though this provides a more efficient way to run the electricity networks, minimizing power losses and wastage through overproduction, it has made them much more vulnerable to space weather. The high-power grids act as particularly efficient antennas, channelling enormous direct currents into the power transformers.

The second problem is the grid's interdependence with the systems that support our lives: water and sewage treatment, supermarket delivery infrastructures, power station controls, financial markets and many others all rely on electricity. Put the two together, and it is clear that a repeat of the Carrington event could produce a catastrophe the likes of which the world has never seen. "It's just the opposite of how we usually think of natural disasters," says John Kappenman, a power industry analyst with the Metatech Corporation of Goleta, California, and an advisor to the NAS committee that produced the report. "Usually the less developed regions of the world are most vulnerable, not the highly sophisticated technological regions."

According to the NAS report, a severe space weather event in the US could induce ground currents that would knock out 300 key transformers within about 90 seconds, cutting off the power for more than 130 million people (see map). From that moment, the clock is ticking for America.

First to go - immediately for some people - is drinkable water. Anyone living in a high-rise apartment, where water has to be pumped to reach them, would be cut off straight away. For the rest, drinking water will still come through the taps for maybe half a day. With no electricity to pump water from reservoirs, there is no more after that.

There is simply no electrically powered transport: no trains, underground or overground. Our just-in-time culture for delivery networks may represent the pinnacle of efficiency, but it means that supermarket shelves would empty very quickly - delivery trucks could only keep running until their tanks ran out of fuel, and there is no electricity to pump any more from the underground tanks at filling stations.

Back-up generators would run at pivotal sites - but only until their fuel ran out. For hospitals, that would mean about 72 hours of running a bare-bones, essential care only, service. After that, no more modern healthcare.

72 hours of healthcare remaining

The truly shocking finding is that this whole situation would not improve for months, maybe years: melted transformer hubs cannot be repaired, only replaced. "From the surveys I've done, you might have a few spare transformers around, but installing a new one takes a well-trained crew a week or more," says Kappenman. "A major electrical utility might have one suitably trained crew, maybe two."

Within a month, then, the handful of spare transformers would be used up. The rest will have to be built to order, something that can take up to 12 months.

Even when some systems are capable of receiving power again, there is no guarantee there will be any to deliver. Almost all natural gas and fuel pipelines require electricity to operate. Coal-fired power stations usually keep reserves to last 30 days, but with no transport systems running to bring more fuel, there will be no electricity in the second month.

30 days of coal left

Nuclear power stations wouldn't fare much better. They are programmed to shut down in the event of serious grid problems and are not allowed to restart until the power grid is up and running.

With no power for heating, cooling or refrigeration systems, people could begin to die within days. There is immediate danger for those who rely on medication. Lose power to New Jersey, for instance, and you have lost a major centre of production of pharmaceuticals for the entire US. Perishable medications such as insulin will soon be in short supply. "In the US alone there are a million people with diabetes," Kappenman says. "Shut down production, distribution and storage and you put all those lives at risk in very short order."

Help is not coming any time soon, either. If it is dark from the eastern seaboard to Chicago, some affected areas are hundreds, maybe thousands of miles away from anyone who might help. And those willing to help are likely to be ill-equipped to deal with the sheer scale of the disaster. "If a Carrington event happened now, it would be like a hurricane Katrina, but 10 times worse," says Paul Kintner, a plasma physicist at Cornell University in Ithaca, New York.

In reality, it would be much worse than that. Hurricane Katrina's societal and economic impact has been measured at $81 billion to $125 billion. According to the NAS report, the impact of what it terms a "severe geomagnetic storm scenario" could be as high as $2 trillion. And that's just the first year after the storm. The NAS puts the recovery time at four to 10 years. It is questionable whether the US would ever bounce back.

4-10 years to recover

"I don't think the NAS report is scaremongering," says Mike Hapgood, who chairs the European Space Agency's space weather team. Green agrees. "Scientists are conservative by nature and this group is really thoughtful," he says. "This is a fair and balanced report."

Such nightmare scenarios are not restricted to North America. High latitude nations such as Sweden and Norway have been aware for a while that, while regular views of the aurora are pretty, they are also reminders of an ever-present threat to their electricity grids. However, the trend towards installing extremely high voltage grids means that lower latitude countries are also at risk. For example, China is on the way to implementing a 1000-kilovolt electrical grid, twice the voltage of the US grid. This would be a superb conduit for space weather-induced disaster because the grid's efficiency to act as an antenna rises as the voltage between the grid and the ground increases. "China is going to discover at some point that they have a problem," Kappenman says.

Neither is Europe sufficiently prepared. Responsibility for dealing with space weather issues is "very fragmented" in Europe, says Hapgood.

Europe's electricity grids, on the other hand, are highly interconnected and extremely vulnerable to cascading failures. In 2006, the routine switch-off of a small part of Germany's grid - to let a ship pass safely under high-voltage cables - caused a cascade power failure across western Europe. In France alone, five million people were left without electricity for two hours. "These systems are so complicated we don't fully understand the effects of twiddling at one place," Hapgood says. "Most of the time it's alright, but occasionally it will get you."

The good news is that, given enough warning, the utility companies can take precautions, such as adjusting voltages and loads, and restricting transfers of energy so that sudden spikes in current don't cause cascade failures. There is still more bad news, however. Our early warning system is becoming more unreliable by the day.

By far the most important indicator of incoming space weather is NASA's Advanced Composition Explorer (ACE). The probe, launched in 1997, has a solar orbit that keeps it directly between the sun and Earth. Its uninterrupted view of the sun means it gives us continuous reports on the direction and velocity of the solar wind and other streams of charged particles that flow past its sensors. ACE can provide between 15 and 45 minutes' warning of any incoming geomagnetic storms. The power companies need about 15 minutes to prepare their systems for a critical event, so that would seem passable.

15 minutes' warning

However, observations of the sun and magnetometer readings during the Carrington event shows that the coronal mass ejection was travelling so fast it took less than 15 minutes to get from where ACE is positioned to Earth. "It arrived faster than we can do anything," Hapgood says.

There is another problem. ACE is 11 years old, and operating well beyond its planned lifespan. The onboard detectors are not as sensitive as they used to be, and there is no telling when they will finally give up the ghost. Furthermore, its sensors become saturated in the event of a really powerful solar flare. "It was built to look at average conditions rather than extremes," Baker says.

He was part of a space weather commission that three years ago warned about the problems of relying on ACE. "It's been on my mind for a long time," he says. "To not have a spare, or a strategy to replace it if and when it should fail, is rather foolish."

There is no replacement for ACE due any time soon. Other solar observation satellites, such as the Solar and Heliospheric Observatory (SOHO) can provide some warning, but with less detailed information and - crucially - much later. "It's quite hard to assess what the impact of losing ACE will be," Hapgood says. "We will largely lose the early warning capability."

The world will, most probably, yawn at the prospect of a devastating solar storm until it happens. Kintner says his students show a "deep indifference" when he lectures on the impact of space weather. But if policy-makers show a similar indifference in the face of the latest NAS report, it could cost tens of millions of lives, Kappenman reckons. "It could conceivably be the worst natural disaster possible," he says.

The report outlines the worst case scenario for the US. The "perfect storm" is most likely on a spring or autumn night in a year of heightened solar activity - something like 2012. Around the equinoxes, the orientation of the Earth's field to the sun makes us particularly vulnerable to a plasma strike.

What's more, at these times of year, electricity demand is relatively low because no one needs too much heating or air conditioning. With only a handful of the US grid's power stations running, the system relies on computer algorithms shunting large amounts of power around the grid and this leaves the network highly vulnerable to sudden spikes.

If ACE has failed by then, or a plasma ball flies at us too fast for any warning from ACE to reach us, the consequences could be staggering. "A really large storm could be a planetary disaster," Kappenman says.

So what should be done? No one knows yet - the report is meant to spark that conversation. Baker is worried, though, that the odds are stacked against that conversation really getting started. As the NAS report notes, it is terribly difficult to inspire people to prepare for a potential crisis that has never happened before and may not happen for decades to come. "It takes a lot of effort to educate policy-makers, and that is especially true with these low-frequency events," he says.

We should learn the lessons of hurricane Katrina, though, and realise that "unlikely" doesn't mean "won't happen". Especially when the stakes are so high. The fact is, it could come in the next three or four years - and with devastating effects. "The Carrington event happened during a mediocre, ho-hum solar cycle," Kintner says. "It came out of nowhere, so we just don't know when something like that is going to happen again."

When hell comes to Earth

Severe space weather events often coincide with the appearance of sunspots, which are indicators of particularly intense magnetic fields at the sun's surface.

The chaotic motion of charged particles in the upper atmosphere of the sun creates magnetic fields that writhe, twist and turn, and occasionally snap and reconfigure themselves in what is known as a "reconnection". These reconnection events are violent, and can fling out billions of tonness of plasma in a "coronal mass ejection" (CME).

If flung towards the Earth, the plasma ball will accelerate as it travels through space and its intense magnetic field will soon interact with the planet's magnetic field, the magnetosphere. Depending on the relative orientation of the two fields, several things can happen. If the fields are oriented in the same direction, they slip round one another. In the worst case scenario, though, when the field of a particularly energetic CME opposes the Earth's field, things get much more dramatic. "The Earth can't cope with the plasma," says James Green, head of NASA's planetary division. "The CME just opens up the magnetosphere like a can-opener, and matter squirts in."

The sun's activity waxes and wanes every 11 years or so, with the appearance of sunspots following the same cycle. This period isn't consistent, however. Sometimes the interval between sunspot maxima is as short as nine years, other times as long as 14 years. At the moment the sun appears calm. "We're in the equivalent of an idyllic summer's day. The sun is quiet and benign, the quietest it has been for 100 years," says Mike Hapgood, who chairs the European Space Agency's space weather team, "but it could turn the other way." The next solar maximum is expected in 2012.

Oh, that explains it

Psychological analysts looking for the reason Barack Obama is rushing pell mell to destroy the American economy, culture, and general way of life need look no further; the answer comes from a noted psychologist from Israel, an expert on Narcissism. It seems our beloved new president is suffering from something called Narcissic Personality Disorder. In layman's terms, he is head over heels in love with himself, and this, according to Dr. Sam Vaknin, makes him extremely dangerous.

Dr. Vaknin States,

"I must confess I was impressed by Sen.Barack Obama from the first time I saw him. At first I was excited to see a black candidate. He looked youthful, spoke well, appeared to be confident - a wholesome presidential package. I was put off soon, not just because of his shallowness but also because there was an air of haughtiness in his demeanor that was unsettling. His posture and his body language were louder than his empty words. Obama's speeches are unlike any political speech we have heard in American history. Never a politician in this land had such quasi "religious" impact on so many people. The fact that Obama is a total incognito with zero accomplishment, makes this inexplicable infatuation alarming. Obama is not an ordinary man. He is not a genius.. In fact he is quite ignorant on most important subjects."

Barack Obama is a narcissist.

Dr. Sam Vaknin, the author of the Malignant Self Love believes "Barack Obama appears to be a narcissist." Vaknin is a world authority on narcissism. He understands narcissism and describes the inner mind of a narcissist like no other person. When he talks about narcissism everyone listens. Vaknin says that Obama's language, posture and demeanor, and the testimonies of his closest, dearest and nearest suggest that the Senator is either a narcissist or he may have narcissistic personality disorder (NPD). Narcissists project a grandiose but false image of themselves. Jim Jones, the charismatic leader of People's Temple, the man who led over 900 of his followers to cheerfully commit mass suicide and even murder their own children was also a narcissist. David Koresh, Charles Manson, Joseph Koni, Shoko Asahara, Stalin, Saddam, Mao,Kim Jong Ill and Adolph Hitler are a few examples of narcissists of our time. All these men had a tremendous influence over their fanciers. They created a personality cult around themselves and with their blazing speeches elevated their admirers, filled their hearts with enthusiasm and instilled in their minds a new zest for life. They gave them hope! They promised them the moon, but alas, invariably they brought them to their doom. When you are a victim of a cult of personality, you don't know it until it is too late. One determining factor in the development of NPD is childhood abuse.

"Obama's early life was decidedly chaotic and replete with traumatic and mentally bruising dislocations," says Vaknin. "Mixed-race marriages were even less common then. His parents went through a divorce when he was an infant (two years old). Obama saw his father only once again, before he died in a car accident.. Then his mother re-married and Obama had to relocate to Indonesia, a foreign land with a radically foreign culture, to be raised by a step-father. At the age of ten, he was whisked off to live with his maternal (white)grandparents. He saw his mother only intermittently in the following few years and then she vanished from his life in 1979. She died of cancer in 1995".

One must never underestimate the manipulative genius of pathological narcissists. They project such an imposing personality that it overwhelms those around them. Charmed by the charisma of the narcissist, people become like clay in his hands. They cheerfully do his bidding and delight to be at his service. The narcissist shapes the world around himself and reduces others in his own inverted image. He creates a cult of personality. His admirers become his co-dependents. Narcissists have no interest in things that do not help them to reach their personal objective. They are focused on one thing alone and that is power. All other issues are meaningless to them and they do not want to waste their precious time on trivialities. Anything that does not help them is beneath them and do not deserve their attention.

If an issue raised in the Senate does not help Obama in one way or another, he has no interest in it. The "present" vote is a safe vote. No one can criticize him if things go wrong. Those issues are unworthy by their very nature because they are not about him. Obama's election as the first black president of the Harvard Law Review led to a contract and advance to write a book about race relations.

The University of Chicago Law School provided him a lot longer than expected and at the end it evolved into, guess what? His own autobiography! Instead of writing a scholarly paper focusing on race relations, for which he had been paid, Obama could not resist writing about his most sublime self. He entitled the book Dreams from My Father.

Not surprisingly, Adolph Hitler also wrote his own autobiography when he was still nobody. So did Stalin. For a narcissist no subject is as important as his own self. Why would he waste his precious time and genius writing about insignificant things when he can write about such an august being as himself? Narcissists are often callous and even ruthless. As the norm, they lack conscience. This is evident from Obama's lack of interest in his own brother who lives on only one dollar per month.

A man who lives in luxury, who takes a private jet to vacation in Hawaii, and who has raised nearly half a billion dollars for his campaign (something unprecedented in history) has no interest in the plight of his own brother. Why? Because, his brother cannot be used for his ascent to power.

A narcissist cares for no one but himself. This election is like no other in the history of America. The issues are insignificant compared to what is at stake. What can be more dangerous than having a man bereft of conscience, a serial liar, and one who cannot distinguish his fantasies from reality as the leader of the free world? I hate to sound alarmist, but one is a fool if one is not alarmed. Many politicians are narcissists They pose no threat to others...They are simply self serving and selfish.

Obama evidences symptoms of pathological narcissism, which is different from the run-of-the-mill narcissism of a Richard Nixon or a Bill Clinton for example. To him reality and fantasy are intertwined. This is a mental health issue, not just a character flaw. Pathological narcissists are dangerous because they look normal and even intelligent. It is this disguise that makes them treacherous.

Today the Democrats have placed all their hopes in Obama. But this man could put an end to their party. The great majority of blacks have also decided to vote for Obama. Only a fool does not know that their support for him is racially driven. This is racism, pure and simple. The downside of this is that if Obama turns out to be the disaster I predict, he will cause widespread resentment among the whites.

The blacks are unlikely to give up their support of their man. Cultic mentality is pernicious and unrelenting. They will dig their heads deeper in the sand and blame Obama's detractors of racism. This will cause a backlash among the whites.

The white supremacists will take advantage of the discontent and they will receive widespread support. I predict that in less than four years, racial tensions will increase to levels never seen since the turbulent 1960's.

Obama will set the clock back decades... America is the bastion of freedom. The peace of the world depends on the strength of America, and its weakness translates into the triumph of terrorism and victory of rogue nations.

It is no wonder that Ahmadinejad, Hugo Chavez, the Castrists, the Hezbollah, the Hamas, the lawyers of the Guantanamo terrorists and virtually all sworn enemies of America are so thrilled by the prospect of their man in the White House. America is on the verge of destruction. There is no insanity greater than electing a pathological narcissist as president.
