How a Solar Storm Two Years Ago Nearly Caused a Catastrophe On Earth
schwit1 writes: On July 23, 2012, the sun unleashed two massive clouds of plasma that barely missed a catastrophic encounter with the Earth's atmosphere. These plasma clouds, known as coronal mass ejections (CMEs), comprised a solar storm thought to be the most powerful in at least 150 years.
"If it had hit, we would still be picking up the pieces," physicist Daniel Baker of the University of Colorado tells NASA. Fortunately, the blast site of the CMEs was not directed at Earth. Had this event occurred a week earlier when the point of eruption was Earth-facing, a potentially disastrous outcome would have unfolded.
"Analysts believe that a direct hit could cause widespread power blackouts, disabling everything that plugs into a wall socket. Most people wouldn't even be able to flush their toilet because urban water supplies largely rely on electric pumps. ... According to a study by the National Academy of Sciences, the total economic impact could exceed $2 trillion, or 20 times greater than the costs of a Hurricane Katrina. Multi-ton transformers damaged by such a storm might take years to repair." Steve Tracton put it this way in his frightening overview of the risks of a severe solar storm: "The consequences could be devastating for commerce, transportation, agriculture and food stocks, fuel and water supplies, human health and medical facilities, national security, and daily life in general."

Every single water filtration plant has very large diesel generators that can run the place for months without electrical power. And no, a solar flare can not burn out giant motors and generators, all that can be ran easily without the SCADA system. In fact we used to run drills operating the place by hand, as most of the guys that did it from 1940 until 1990 did it mostly by hand.
Do not look at laser with remaining good eye.
Really? This would be devastating? We can't live without electricity, electronics, water pumps? It's amazing we're here today!
ISPs such as Verizon and Comcast would have been forced to upgrade their equipment which means some of the bottlenecks that currently exist wouldn't exist afterwards (though let's be honest, they will find some other excuse to keep speeds slow).
And yes, this is a Broken Window-type fallacy though in this case, it wasn't deliberate.
Also, there would be a temporary boost in productivity and spending as all this equipment, in general, is replaced though whether that would offset the loss of productivity and people having nervous breakdowns because of their Pavlovian need to check their email and texts every ten seconds is debatable.
We will bankrupt ourselves in the vain search for absolute security. -- Dwight D. Eisenhower
And yet nothing changes, there is no hardening of infrastructure, no preparation or planning.

The sun is clearly a terrorist. I also hear it harbors vast quantities of cheap energy sources. time to INVADE!!! CHARGE!!!
In the 80s, Quebec's power grid got taken out by solar storms. It was particularly susceptible because we have a ton of really long-distance runs:
https://en.wikipedia.org/wiki/...
That one was just bad enough to flip circuit breakers on the grid, but it still caused a 9 hour power outage. Some satellites also lost control.
In Iraq, China, and Detroit, Michigan, USA.
Focus on building the technology to get us OFF this rock!
Every time I see one of these new doomsday scenarios pop up, I know there is a media-savvy researcher somewhere looking to score a big grant.
SJW's don't eliminate discrimination. They just expropriate it for themselves.
Desensitization. Plausible explanation for when they turn everything off on purpose.
There is no doubt that these geomagnetic storms can cause disruptions, but is there any evidence they can do widespread permanent damage? Just look at the 1989 storm that hit Canada, it was an X15 with no real warning but all it did was trip breakers & make lights flicker. Beyond a few random transformers, a temporary disruption of radio signals & maybe a satellite or two taken out most of the doom and gloom predictions regarding these storms have yet to come true. I suppose it could just be we just haven't seen a really big one since the proliferation of electricity, or it could be some are looking for grant/contractor dollars and aren't shy about "stretching" the truth to get them.
That was only in North Carolina.
We could definitely do more, but there have been some changes to try to minimize the damage. The Space Weather Prediction Center tracks and predicts geomagnetic storms and warns power companies, satellite operators & air traffic systems about possible disruptions. I suppose the question would be if they did see a massive storm coming that could do damage would they A: Issue a pointed, timely warning and B: Would the appropriate parties take the necessary actions (shutting down the grid, locking down satellites, etc).
They did, so now they are going to sue the sun.
> "According to a study by the National Academy of Sciences, the total economic impact could exceed $2 trillion,"
Holy Jesus! That's a little bit more than half of what we borrowed those two years!
(-1: Post disagrees with my already-settled worldview) is not a valid mod option.
the problem is not in the solar storms, as they have been happening for billions of years, and will happen for another billions after our "civili"zation is long gone. Note that on the statistical based our observational material for the power of these storms is absolutely insignificant. The problem is our technology, or more the way it has evolved since the beginning of 20th century. Tesla had gone in totally opposite direction, looking and evolving natural way of power distribution and efficient power usage and protection and was solely designing and working with HV systems. Every appliance can be designed to work with HV and high frequency, the natural way of energy distribution, but this was not how the rest of the engineering world looked at the problem, so they and the industry when in totally the other way. Under a such storm virtually all of the Tesla's inventions will just give more power for they were naturally designed to transform such power surges. So the educated reader can go and research, and at least try to build some of these appliances, and educate other people around him/her. The more they know about Tesla and his systems the more humans have chance to face/change the problems that procrastinate our contemporary "civili"zation and as a bonus not to worry about cosmic event of a such type.
Yes, for 6 months the world would have been thrown into chaos. Millions might have even died. But we would have emerged from it stronger and more united as a planet. Imagine just in the USA.
Would Ted Cruz have shut down the government to protest Obamacare after having lived through an event like that? Do you think the Republicans would be global warming deniers if they had gone through an event where the sun struck back at earth and nearly destroyed us?
Suddenly american politics wouldn't be about immigration and shouts of "benghazi" it would be about trying to put the pieces back together and rebuilding our infrastructure rather than spending trillions on a fighter plane that can't fly.
I wish the disaster had happened, because it would focus us on the things that are important, rather than stupid wedge issues meant to keep the serfs arguing with each other rather than realizing their masters are incompetent.
If telephones are outlawed, then only outlaws will have telephones.
Actually, we know how to make hardened electronics, and we do make them.
But it does NOT come cheap, you have to add a number of protection (clamp) diodes to *EVERY SINGLE GATE* inside integrated circuits, for example. You've read that right: on a modern microprocessor, that's close to a billion extra diodes at the very least. These not only take up die space, they also cause other nasty issues re. signal integrity and low-voltage operation, especially at very high frequencies. Any interconects have to be sized to be able to deal with currents induced by a high dV/ds and high dV/dt (voltage variation in space or time), including those inside the chip. And you need an extra-tick discharge ground plane, which causes capacitancy problems (i.e. signal degradation on high-frequency operation).
And lots of protection circtuitry everywhere else, plus very effective ground shielding, and overvoltage peak clampers everywhere you have more than a few centimeters of any sort of conductor. It adds a lot of bulk, and it is expensive.
It is also standard fare for EMP-hardened military-grade portable devices that cannot be shielded behind several inches of stupidly well-grounded steel/copper faraday cages all the time, so it can be done. But "portable" in military speak can easily weight 30kg :-p
But we will have advanced warning!
Because photons have a known expectation of creating electro positron pairs, which are retarded by the suns gravity, we can detect the neutrinos in advance!
Just need to get the response time down to 10 millisecs and...
Oh, wait...
"Most people wouldn't even be able to flush their toilet because urban water supplies largely rely on electric pumps. "
Um, no.
First, the normal flush pressure comes from the water tank on the back...so EVERYONE would be able to flush at least once. (Actually, in a disaster, that tank isn't a bad source of freshwater, at least for a while.)
Most communities have water tanks above their population, either on a nearby height, or in water towers. This makes the system - at least in the short term, until that tank is drained - impervious to power outage. Even NYC has tens of thousands of rooftop tanks with the same function, but on a per-building level.
GRAVITY, not electricity, produces water pressure that refills that local toilet tank. So until the community tank is emptied, and electric pumps are required to fill that large tank, everyone would be able to flush just fine.

These scenarios are always full of maybe, possibility, chance, etc. without much actual risk analysis. Severe cold snaps regularly plunge large areas into darkness for days. People switch to candles and gas heaters instead of suddenly reverting to the middle ages. Most infrastructure generally fails quite regularly from poor design or maintenance, without any extra-terrestrial assistance.
I guess 'Solar wind may inconvenience a lot of people' doesn't sell as well as 'We're all doomed, head for the hills'
reading all this stuff of potential disasters... is it numbing our sense of urgency? There was a time when we had no idea of many dynamics of the Sun (there were no spacecraft). It is scientifically interesting, an IRIS scientists said the solar system is a system, the sun is not constant and causes non-constant interactions to planets. Speaking of disasters that have happened, might happen, a nearby star can go supernova. Or there could be a nearby gamma ray burst. But looming catastrophe is shrinking reserves of water that is safe to drink.

Don't get caught unaware by the next major CME. Read the space weather forecast from NOAA.
Your fantasies contain the seeds of important concepts.
Why don't we harden the electrical grid for this? What technologies could be used to protect electrical systems from this? Maybe this would involve a system to suppress the surge but also a system of disconnect switches that could be remotely activated to disconnect the electrical grid? What sorts of systems could be installed to prevent such a catastrophe? Could we install disconnect switches around transformers and such? What about unplugging your household appliances and electronics? Would that protect them from being hit? Its astonishing considering this is the greatest threat we havent taken more effort to install protective systems.
I remember a lot of the same FUD from Y2K and was almost caught up in it.
Let's take a look at the practical problem:
Q: "How do we shield from CME?"
A: We don't.
A lot of humanity lives above the surface and not only that, but our infrastructure is also mostly at the surface as well. If all the power lines were below the surface this wouldn't be quite an issue, but the supply lines would still be in trouble. If a CME hits Wall St. Dead on, that's it, consider the stock market toast.
The more likely scenario is 80% of the planet is hit with a CME, of which 10% is hit directly, and actually suffers the damage, everythign cascades away from that point. Remember what caused the Baby Booms? A whole lot of nothing better to do.
So in all likeliness a CME hits the middle of the pacific and all that suffers in Hawaii. Worst case scenario is that it hits NYC, London, Moscow, Shanghai or Tokyo and damages infrastructure enough that the economy grinds to a halt. As long as someone survives, we're good.
Footnote:
Why aren't we building data centers UNDER ROCK and isolating them? I have to wonder what will happen to the various "cloud" servers.
Bunch of astrophysicists walk into a bar. First one orders a gin and tonic, and gets it. Second one orders a red wine, and gets it. Third one orders a Mexican beer, at which point the bartender yells "all right, that's it, everybody out!" Another bar customer asks the first astrophysicist "what's going on?" He responds "Coronal mass ejection."
Nothing will be done. Nothing. It profits nobody immediately.
I expect Morgan Freeman, Tom Hanks, Uma Thurman, and Cameron Diaz (with cameos by Dolly Parton and Emma Watson) to make a movie about this immediately. "The Corona"
Apart from mechanical pumps who assure the survival of comatose patients, I can think of some other vital devices -- pacemakers, for instance.
How would they be affected? Is there a way to change them to make safer? (incredibly, an arrangement of magnets and an external winding device could be possibly safer in that atypical situation... though kinda steam-punk).

Ah, bet you're thinking - what an asshat, right?!
No, see - the thing about such natural disasters is that they tend to bring out the best in us, sometimes we need a crisis like that when we're too spoiled and too set in our ways to help fellow man (or nature) out, history shows that these disasters often bring out the better in us and replenish life and give jobs and hopes to those who have none.
It will also serve as a reminder that will be remembered for decades - how vulnerable we are, and that we should prepare and stop taking everyday life for granted.
What this world is coming to - is for you and me to decide.

Correction: they'd be able to flush once. Make it count!

On July 23, 2012, the sun unleashed two massive clouds of plasma that barely missed a catastrophic encounter with the Earth's atmosphere ... Had this event occurred a week earlier when the point of eruption was Earth-facing ...
The sun's rotational period is about 25 days, meaning if it missed pointing at us by a week, then is was shooting into the solar system at a 100 degree angle from us. That doesn't sound to me like a "barely". CMEs happen all the time, and yes this one was a pretty big one, but out of 360 degrees around (2*Pi for those elsewhere), and some amount of degrees off of vertical (I believe CMEs are ejected mostly from the sun's equator region), you could fire one every couple days and the Earth would hardly notice. It's kind of like someone firing a gun into the air - 99.9% of the bullets go where no harm is done, though there is that 0.1% to worry about. Saying a bullet landed 10 blocks away doesn't sound to me like I barely missed getting hit, even if it was a very big bullet.
There is plenty of misinformation, exaggeration and also ignorance about the potential threat of CMEs and other solar events. Many have justly referred to the Carrington but because it occurred during a time in human civilization when we were not at all "dependent" on electrical infrastructure and computers it is hard to infer the current danger of such a thing. It is sobering to note that although it is hard to predict what would happen in our time if such an event were to occur, it is an obviously safe conclusion to make that such an event might occur again.
I thought all our infrastructure was going to fail in 2000.
I get the impression you're not talking about cars, batteries and charging stations...
Language students: Don't try to learn English here. This ain't it.
Google says:
Therefore the probability of being hit by a given CME is (2.8 x 10^17) / (5.1 x 10^8) = 5.5 x 10^-8, or a 0.0000055% chance.
Now the number of CMEs per year is actually higher than I expected, which I suppose explains why we do in fact get hit between 0 - 70 times per year. However the number of annual large CMEs is quite low, with none of the sites I visited actually agreeing on the number (most seemed to agree it's less than 5 per year in a solar maximum.) Let's say there are 5 per year. That only brings the chance of being hit by one of them up to 0.000028% per year. So if I live to be 100, the chances I'll see one in my lifetime are only 0.0028%.
caveat: These calculations ignore CME cross-section (essentially width and height) and duration (essentially length), since I couldn't find any accurate information on those. If you find those, you can factor them into these calculations by multiplying by the cross-section, multiplying by the % duration that the CME's strength is high, and multipyling by the Earth's average orbital velocity. That will modify the probility to take into account the volume of space the Earth occupies while the CME is traversing the edge of our 1 AU sphere, and how much of the surface of the sphere is touched by the CME.

Barely missed? So you're saying it didn't miss?
Close but so far.
Diesel engines almost all have glow plugs which provide additional heat for starting the engine when cold. Once started and running near operating temperature the glow plugs shut off.
The problem is not the law of physics, it is the technology implementation. Try using any of your electronic devices to a HV rapidly pulsating (2-3K cycles will suffice) in air (basic dielectric(, electrostatic field and you will get the idea. And lets not go to the "laws" of physics for Nature does not recognize our human defined laws about it, for ALL of them (our laws) brake, under more or less extremes conditions. And a point here it is good to go back in the pioneers of the electrical physics and engineering (Maxwell, Heaviside, Tesla, Lord Kelvin, Steinmetz, C. A. Bjerknes and several others fellows) in order to understand the present inefficiencies.
If you are interested in stuff like this be sure to check in with the daily "weather" report from http://www.Suspicious0bservers.org (yes that is a zero).
Great source of daily information of whats up and whats happening.
Sure, disasters bring out the best in many (maybe even most) people. However, they also bring out the worst in people who are best described as predators. And there are a *lot* of those predators out there.
A crisis like what is described in the article would result in *millions*, maybe even *tens* of millions, of deaths in the US alone. (Ironically, less 'developed' nations would fare better due to their respective *lack* of widespread tech infrastructure.
Or there could be a nearby gamma ray burst.
There isn't much point in worrying about this. About the only people that would be spared on the side of the earth that was exposed would be people that were already underground/under water at the time. How far underground/under water would depend on the intensity of the gamma rays. Even if we detected a burst of neutrinos to alert us that something was coming, it wouldn't be enough warning for anyone to take shelter that wasn't already there. I guess if you really wanted to be safe you could live a few hundred feet down in an old mine, but that would rather suck.
If you don't like to see stories like this, here is what you can do about it.
Go find a cliff or a bridge somewhere, then take your entire fucktarded family.
Have all of them jump off to their deaths, and after that jump to your's.
You wouldn't have to see these fucking stories anymore and we wouldn't have to put up with whiny little fucktarded bitches like you again.
And why is that not taught in school? Any idea?
Sigh ... we use high frequencies quite a lot ... ever figured how a classic TV works?

Fans? AC? No there's a far more fundamental problem.
I read an opinion piece once that postulated that if electricity suddenly stopped for extended periods we wouldn't me uncomfortable, we'd likely be dead. Before electricity the human race was somewhat disperse. Towns were littered everywhere and major towns had limited populations. As we the human species have congregated in major cities, and those cities have grown, our dependence on electricity is now total.
Water pumps? that kind of thing is supplied by backups. I would not worry about our water system in an extended nation wide blackout.
What I would worry is the ability to move. A city can grind to a halt when an intersection is out, imagine if they are all out.
What I would worry about is the ability to eat. Refrigeration is a cornerstone of our supply chain. Supermarkets couldn't function without electricity to run refrigeration, and without this food storage systems we wouldn't be able to feed the large population that has congregated away from the primary industry which feeds it. Hell I think back to the flood which occurred in my city in 2011. The local supermarkets actually ran out of bread, milk and water. The flood lasted 2 days and didn't actually cut off all of our highways. We couldn't make it 2 bloody days without panic buying, and stocking out food supplies in the city.
On that note, what I would worry about is other people. Looting, rioting and basic survival instincts. People have the intellectual capability of a turnip during a crisis situation. In the same 2011 flood I saw some lady lose it in a supermaket after buying the last 15 loaves of bread. She was told she could only have 2 loaves so she decided to throw the lot on the ground and trample it screaming "If I can't have it then nobody can!" To reiterate this was a 2 day flood. Where she intended to store 15 loaves of bread in a city with 30 degree average temperature and an 85% average humidity without it going mouldy I have no idea. Likewise the fact we stocked out of bottled water was alarming given there was nothing wrong with our taps or water supply.
The problem is not that we can't live without electricity, but rather we'll likely kill each other without electricity.
It wasn't even close to earth. That is like talking about a car crash at an intersection that you use every day at 1pm but the crash happened at 1 am. WTF.
