The Underappreciated Risks of Severe Space Weather
circletimessquare notes a New Scientist piece calling attention to a recent study by the National Academy of Sciences, which attempts to raise awareness of the dangers of severe solar electromagnetic storms. "In 1859, amateur astronomer Richard Carrington noticed 'two patches of intensely bright and white light' near some sunspots. At the same time, Victorian era magnetometers went off the charts, stunning auroras were being viewed at the equator, and telegraph networks were disrupted — sparks flew from terminals and ignited telegraph paper on fire. It became known as the Carrington event, and the National Academy of Sciences worries about the impact of another such event today and the lack of awareness among officials. It would induce un-designed-for voltages in all high-voltage, long-distance power lines, and destroy transformers, as Quebec learned in 1989. Without electricity, water would stop flowing from the tap, gasoline would stop being pumped, and health care would cease after the emergency generators gave up the ghost after 72 hours. Replacing all of the transformers would take months, if not years. The paradox would be that underdeveloped countries would fare better than developed ones. Our only warning system is a satellite called the Advanced Composition Explorer, in solar orbit between the Sun and the Earth. It is 11 years old and past its planned lifespan. It might give us as much as 15 minutes of warning, and transformers might be able to be disconnected in time. But currently no country has such a contingency plan."
Kinda funny that wacky survivalists might have the last laugh in an event like this.
Just as long as the space weather doesn't render my firearms inoperable ;)

We are the United States Government! We don't do that sort of thing.
I remember when the northeast US had a power outage that lasted a few days just a few years back. It was no where near as dramatic or dire as this summary suggests the situation could be. I still had water and gas in Ohio.
Then you should RTFA. I read this article yesterday and toyed with submitting it but didn't bother. One of the things that could happen with a large enough space weather event is the destruction of distribution transformers on a region wide (nationwide in the case of small countries like the Scandinavian ones) scale.
No power utility has enough spare distribution transformers on hand to replace all of them after they go. They are usually built to order and take 12 months or more to produce. So why don't you imagine a power outage that lasts for months or years across the entire Northeast United States and tell me how undramatic it is? No refrigeration, no gasoline for your car (no electric to pump it through pipelines or service stations), limited and rationed modern medicine, no pumped potable water, no water treatment plants, no HVAC systems, limited communications, etc, etc, etc.
Sound dire enough to take seriously now?

Yes, it could take days for the power to come back
Try months or years if the event is large enough to destroy transformers on a region or nationwide scale.

That's just flat out wrong.
ACE might have a better ground network (let's face it, it's easier to talk to as it's at L1), but STEREO-Behind can see areas of the sun that aren't visible from any other solar-observing mission. It's also remote sensing (ie, telescopes), so it doesn't have to wait until it gets hit by an event. (at which point, we're looking at the last 1M miles of a 93M mile trip)
There's also instruments that have proven space-weather benefits on SOHO, but that's even older than ACE. I'm not going to say that ACE isn't the most important satellite in NOAA's eyes for predicting space weather (and some of their space weather folks have even mentioned that they might have to put up a similar satellite when ACE finally fails), but saying it's the only warning system discounts all of the other solar-observing missions used for space weather forecasting.
Build it, and they will come^Hplain.
So let me get this straight.
You're suggesting that because a freak event may or may not happen in someone's lifetime that they should consider living a life that they personally found miserable, so that they could point and say "Hah! I told you so!" for a few days before everyone gets power back and start playing on their XBox's in their nice warm heated houses again?
I'm not convinced it's worth drastically altering your life away from what you know and enjoy for something that may or may not ever actually happen and when it does would realistically just inconvenience you for a short period of time before getting back to normal (it wouldn't be as bad as the summary/article suggests anymore than we'd be getting blown up by terrorists daily if we listened to the Bush/British governments).
The article cites Quebec in 1989 as an example, yet today Quebec doesn't seem to be the desolate Fallout style wasteland where everyone is fending for themselves and millions die that the article infers might happen.
It's a question of the odds. A major electrical storm occurred within the last couple of centuries. A major asteroid impact - of the sort that would do worse damage to a wide area (not just knock down some trees in Russia) - haven't seen one probably since we dropped down from the trees.
Whether you're losing sleep over it is one thing. whether we, when awake in the daytime, should be hardening our electrical grid against surges from space - well, that's a real question. Prudence doesn't mean just acting when you get scared enough that you can't sleep at night.

As a cyborg (literally, if technically) I have to wonder what such a solar electrical storm would do to implanted electronic medical devices, such as my pacemaker. Any knowledgeable insights? If this shuts down, I'm history in seconds.
Can we get a "-1 Wrong" moderation option?
If you don't think loss of the entire power grid would deeply affect your life, I have to wonder where you live (and that's being kind)
As much as the thought of millions of pampered city dwellers wailing helplessly in the darkness might amuse me, I can not imagine that their lives are so different to country people as to make survival a difficult prospect.
There are a number of potential problems that us pampered city dwellers have to deal with in the case of an extended power outage that simply aren't as much of a problem in rural areas, such as:
1. Traffic lights being shut down, which can grind traffic and thus commerce to a halt.
2. Crime.
3. Panicking people who don't have the sense to just wait it out.
And of course, most everyone who works in technical jobs is out of work until the power comes back on.
I am officially gone from
Last time a major TEOTWAWKI event was looming (Y2K), I described the threat to my father in great detail. His response: [shrug] "I'll throw another log on the fire and go back to my book." True enough, my folks' lives are pervaded by self-sufficiency, including extensive wood heat, well water and homegrown food. Society shuts down, they just spend a few minutes adjusting and carry on.
But ... you wouldn't guess that at a glance. They have elegantly integrated the survivalist mindset with modern conveniences, enjoying everything technology has to offer without worries of what to do if the grid shuts down indefinitely. Everything has a low-tech backup, preparations for self-sufficiency are ongoing and already in use.
You can live a "survivalist" lifestyle, and still be fully "wired". The two ways of life are not diametrically opposed.

They go boom, they get replaced or otherwise repaired. The situation if so drastic would right itself due to economic forces that encourage such.
What part of 12 months to build them is so hard to understand? Even if that timescale could be shortened do you think the infrastructure exists to produce large numbers of these items in a short period of time? Yes the situation would eventually right itself through economic and other factors. Yes the human race would survive. But you'd still have hundreds of millions of people without power and the benefits of modern civilization for months. Almost every single piece of technology that supports civilization (particularly high population density civilization) depends on the electrical grid
I could imagine alongside you all day, but it won't ever come to pass. Have fun RTFA.
It has come to pass in the past. Within the last 200 years as a matter of fact. If a similiar event happened today (the whole point of the article that you apparently refuse to read) it would wreck havoc with modern infrastructure. In 1859 all that existed to disrupt were telegraph networks. Today our entire civilization depends on infrastructure that is vulnerable.
Sticking your head in the sand and refusing to even read the article might be typical /. behavior but all it accomplishes in the end is to confirm your ignorance.

I really expect more from these guys.
That the power grid in this country would become a set of large antennas during a "carrington event" is an interesting problem. Inducted current would be tremendous. There would be fires, almost certainly, and blown transformers. Fusable links might help with the transformer issue, but I'm sure that some significant amount of transformer capability would be taken offline. Power stations would likely be immune from meltdown, but I don't know if standard trips would keep them all whole. Let's say that some 50% of the generating capacity (very generous), and 70% of the transformers (possibly low), were taken out by this event. A significant inconvenience, to be sure. Nothing that we, as individuals -- and as a society, could not handle. To assume, like the authors of this article, that the most powerful country in the world would simply roll-over is preposterous.
To propose, seriously, that "Modern Healthcare" would end in 72 hours when the emergency generators ran out of fuel -- this is ridiculous. The article's premise that modern civilization in our country would be thrown back to "third world" conditions is also completely without merit. Not to belittle the situation -- it would, in a word, suck. That said, we would rise to the occasion, I am sure of it.
Let's just, for a moment, reflect on how deep the fuel infrastructure is in this country. A power grid is not required for fuel distribution, though some level of power is required. Pumps that pump diesel can be run by generators, many refineries are capable of using their own product to generate power, and distribution of fuel to Hospitals and the like is a standard emergency procedure. Trains, tanker trucks, and ships continue to run. The transportation infrastructure would remain largely intact beyond the boundaries of very large metropolitan areas. The roads would continue to roll, and with it, teams of people working to fix the problem.
First, the plants, then the substations, then the cities and transmission lines. Would it be hard? Of course it would be hard. But we would continue to make it work, to adapt and overcome, and in the process make it better.
Bullshit, FUD and fearmongering...
In a case of a large scale power-system breakdown you don't go and try to bring it all back up all at once.
And you sure as hell don't sit on your ass crying, mourning the end of civilization and your X-box points.
Instead, teams of experienced technicians (you know... all those people with the various degrees in electrical engineering) start fixing the grid so that they can have parts of it running as soon as possible.
1 transformer, 2 transformers, 3 transformers, 4...
You lack the parts? Pillage the dead transformers. There is a PRETTY good chance you can take 2 or 3 dead ones and have 1 working in under 24 hours.
Fix the ones that CAN be fixed, leave the completely messed up ones for later replacement.
Don't have enough power to power the entire town cause the nation-wide system is down? DON'T.
Give one half of town 12 hours of power and then turn them off for the next 12 hours while the other half gets their 12 hours. Or 8. Or 6.
Hell... During the war (I'm from Bosnia) people used to steal cooling oil from the transformers (you can run chainsaws for cutting wood, and even cars on that stuff), artillery shells would explode next to them drilling them up with shrapnel, even the local power-plant got hit couple of times so bad that technicians had to take it off line to patch the pipes in the cooling towers.
Let me tell you... you get used to 4 hours of electricity per day (or less) VERY fast.
You leave the lights on to wake you up when it comes on.
Charge the batteries, cook, wash clothes, heat up the boiler and then go about your business waiting for better times.
Mit der Dummheit kämpfen Götter selbst vergebens
But aren't these things fairly well shielded anyway?
No, they aren't. The part of the grid that picks up the load is the distribution lines themselves. They aren't shielded in any deployment that I'm aware of and it would probably be prohibitively expensive to do so.
The inductive load imparts a huge amount of DC current onto the AC power grid and trashes the windings in the connected transformers. The defense is to disconnect those transformers from the grid but that only works if you have enough advance warning. Currently we have no formal process to handle this early warning (though the technology does exist) and no plans/procedures in place to disseminate that warning to the power utilities and for them to take action.
RTFA. It's actually a pretty interesting read. It's not a doomsday scenario -- we'd survive as a people and as a country. We'd just suffer some pretty substantial damage in the process.

I should have bought that riot gun instead of a taser. :(
Yeah, the taser isn't going to be real useful for getting yourself food, if it comes to that. Though the image of Bambi lying on the ground screaming "Don't tase me bro!" is kind of amusing ;)

"Wacky survivalists" is an historically very recent notion. For the bulk of mankind's history, having a well stocked larder-stores adequate to get you through to the next harvest season- and the means to supply yourself with adequate shelter and heat and water, etc based on your own and mostly local sources was quite the ordinary norm. It has only been the last two or three generations where that started to fall out of favor.
We have had numerous examples of much smaller and more localized infrastructure destruction, and the best observations have shown that areas start to suffer fast after a three day outage of general modern technology. Just in time delivery systems and centralized power and water and natgas delivery and so on are the main cause of that.without massive outside the region resupply, that's it, civilization falls apart rapidly. Three days isn't very long. If the event/disaster is much longer than three days, and no outside help is coming in (because the next region over is just as bad off, as the region next to that, etc), you'd see some pretty dire circumstances arise.
Here is one example for the US, we no longer maintain a national emergency bulk food stockpile. It used to be millions of bushels of this or that, dried milk and so on. We maintained that for decades, then they stopped and went to what is called set aside. This is due to farming changes and "the market". We- the government "we"- used to pay minimal price controls and stockpile various surplus foods, in order to maintain our domestic agricultural base through wild market swings and seasonal weather variations, but they more or less stopped that some time ago and now we have no stockpiled food, they sold the last of it off earlier last year finally.
In other words, on a very large scale, we have no backup civilization or big national pantry. It doesn't exist, just not there. The government has zero provisions to help the people in general at any national scale sized event. They have provisions to use military force to "stay in charge", they call it "maintaining continuity of government", that's it. We have a national petroleum reserve as the only exception, and it is in the form of just crude, it would still need refining and delivery-that's iffy enough in such a scenario to even be possible- (and even then most would go to the government and not the people).
On the other hand, there is nothing stopping people from instituting their own stores and provisions and having a personal backup protection scheme, the "wacky survivalists" type method that all our ancestors considered normal and a very good idea. In the community we still call it survivalism, but it has a less scary name now too, "practical preparedness". Here is a plain vanilla example, for roughly the same cash people put into a big screen plasma TV they can have a decent amount of long term dried stored food. For what a cheap laptop or other "must have" electronic gadget of the month costs, you can have a pretty decent gravity powered water filter. The folks in suburbia and in the hinterland get laughed at a lot as having unsustainable lifestyles, but they are living in the only places where you can have a rationally large enough local garden and access to alternative water supplies, etc, along with firewood. Choices one can choose now in other words. All the big cities would collapse rapidly in such a national sized electronic disaster as in TFA, it would become beyond ugly, right up to and including cannibalism.
Basically, the government sucks when it comes to national and practical "civil defense". They only have a military solution. The military doesn't produce anything, it just takes it/spends it/wears it out. Look at the recent articles about the relatively small numbers of homeless in California, possibly our richest state. They can't even deal with such a teeny tiny homeless situation at very low numbers adequately. Extrapolate those numbers from thousands to tens of millions or more and it becomes easy to see the problems...
So it is up to the individual now to decide to incorporate a practical preparedness plan and alter lifestyle a little bit, the article scenario is only one of many potential wildcards that could occur.
Doesn't the tendency of an event recurring increase with the passage of time?
This is a common belief, but it is utterly wrong. Consider flipping a fair coin. The probability of getting heads is 1/2 always. If I got heads the last 100 flips, what's the chances of getting heads again? 1/2.
On the other hand, the probability of getting heads 100 times in a row is 1/2^100. Confusing these two probabilities is the basis of the Gambler's Fallacy.
However, there are some natural processes that fall subject to this reasoning. Take the earthquake example. Let's say that the chances of an earthquake happening increase as subterranean pressure increases. Let's say that everyday the subterranean pressure increases by some (small) random amount. In this situation the chance of an earthquake does get bigger everyday, but that's because there is something actively increasing the probability.
Compare with the earth being struck by a cataclysmic asteroid. In this case, there's no analogous process building up over time so it is fallacious to conclude that the chances are getting bigger every day that we don't get struck.
you are clearly ignorant. this is not meant as a throwaway insult, but a qualitative judgment of your words on the subject matter

the issue here has absolutely nothing to do with static electricty, or small electronics. it has to do with electromagnetic induction across long powerlines
