New Studies Warn of Cataclysmic Solar Superstorms (scientificamerican.com) 102

Posted by msmash from the shape-of-things-to-come dept.
A powerful disaster-inducing geomagnetic storm is an inevitability in the near future, likely causing blackouts, satellite failures, and more. From a report: Unlike other threats to our planet, such as supervolcanoes or asteroids, the time frame for a cataclysmic geomagnetic storm -- caused by eruptions from our sun playing havoc with Earth's magnetic field -- is comparatively short. It could happen in the next decade -- or in the next century. All we know is, based on previous events, our planet will almost definitely be hit relatively soon, probably within 100 years. Geomagnetic storms are caused by sunspots, solar flares and coronal mass ejections, resulting in calamities to which our modern technological society is becoming ever more susceptible.

Most experts regard the Carrington Event, a so-called superstorm that occurred in September 1859, as the most powerful geomagnetic storm on record. But new data suggest that a later storm in May 1921 may have equaled or even eclipsed the Carrington Event in intensity, causing at least three major fires in the U.S., Canada and Sweden -- and highlighting the damaging effects these storms can have on Earth today. In a paper published in the journal Space Weather, Jeffrey Love of the U.S. Geological Survey and his colleagues reexamined the intensity of the 1921 event, known as the New York Railroad Storm, in greater detail than ever before.

Although different measures of intensity exist, geomagnetic storms are often rated on an index called disturbance storm time (Dst) -- a way of gauging global magnetic activity by averaging out values for the strength of Earth's magnetic field measured at multiple locations. Our planet's baseline Dst level is about -20 nanoteslas (nT), with a "superstorm" condition defined as occurring when levels fall below -250 nT. Studies of the very limited magnetic data from the Carrington Event peg its intensity at anywhere from -850 to -1,050 nT. According to Love's study, the 1921 storm, however, came in at about -907 nT. "The 1921 storm could have been more intense than the 1859 storm," Love says. "Prior to our paper, [the 1921 storm] was understood to be intense, but how intense wasn't really clear."

        Fortunately they won't. There are circuit breakers throughout the system. There have to be, for maintenance and for dealing with the asshole colliding with a utility pole, bringing it down and shorting the conductors together. Also for dealing with wind storms tearing up poles and transmission towers.

        Search YouTube for substation circuit breaker arcs. Actually breaking the circuit when you're talking about tens of thousands of volts in air is a nontrivial problem, but it is a solved problem. There are six different ways of doing it in common usage. High voltage AC circuit breakers that can break a 765 kV circuit are off the shelf. (In a manner of speaking. Almost no one buys one with that kind of capacity and literally puts it on a shelf. They're too expensive not to use.) Siemens and ABB both sell circuit breakers rated for 1200 kV.

        The grid will be fine after the next Carrington event. Most transformers and generation equipment will have been isolated by their associated circuit breakers. The longest lines are also the lines that routinely carry extremely high voltages and are therefore designed for it. Once generation sources are cut off, ongoing eddy currents induced by the storm don't exceed the normal carrying capacity of the lines. Lines designed for lower voltages also tend to be shorter, so the storm has less room to induce damaging voltages. It will take some time to test everything to be sure the equipment was successfully protected by the breakers, and then a whole lot of big guys with big wrenches will be very busy driving around turning breakers back on in the right order to bring the grid back up in a stable fashion. Trivial, no, but understood. Power companies deal with this sort of thing every time there's a major ice storm or tornado.

          Power transformers are regularly destroyed by much smaller solar storms despite active circuit protection. Alternators and induction motors are susceptible to damage also. A large induction motor used in industry with effectively DC applied across its inputs while running is better imagined than witnessed; think of where the torque is applied when the rotor locks.

        That about sums it up. The DC currents produced in long transmission lines during a geomagnetic storm cause the power transformers at each end to go into saturation which can easily destroy them and the resulting power irregularities can destroy other things. It has happened several times due to lesser storms.

      It would not cause a fire directly. There's no way that such an event could heat up the atmosphere enough to do that.

      However, such an event can induce strong currents in electrical systems -- enough to cause electrical discharges that could start a fire. The 1858 Carrington event caused havoc with telegraph systems all over the world, including discharges.

      Potentially worldwide, per above. As I said, anything long and conducting would be at risk. CPUs might be affected by current surges in the mains, but otherwise probably wouldn't suffer damage. Electronics on satellites, on the other hand, face another risk: the satellites would pick up strong static charges due to the solar wind. Discharges of that built-up charge could cause damage.

      Would it effect the whole earth or just the side that was facing the sun upon event impact?

      The solar wind affects the earth's magnetic field on both sides. It's complicated, but the basics are as follows. On the dayside the solar wind compresses the geomagnetic field and a bow shock develops as the wind is turned aside by the field. The wind streams round the earth and collects for awhile in the geomagnetic tail. Wind built up in the tail separates periodically and continues in the nightward direction, sort of like drips from a faucet. All of this can cause terrestrial EM events on both sides.

    All our power distribution systems are very similar to the telegraph systems that caught on fire during the previous solar storms. These are long cables, tied to a big ass transformer at both ends. These systems are designed for operation at 300kV-400kV, so they are well insulated. The moving magnetic field of the "Solar Storm" or Coronal Mass Ejection is big enough that in the days of the telegraph lines, The generated high voltage arced across the keys, and effectively shorted out the windings that the telegraph lines present to the magnetic fields, setting the equipment, and lines themselves in some cases, on fire. High voltages on the lines were able to jump to ground in some cases, setting the surrounding forests or fields on fire. Now, we have bigger lines, better insulators, and more expensive stuff tied to both ends of these long, high voltage generating cables. The transformers that do power distribution are very large and expensive; they will have to be replaced, and they have a several month leadtime. Disconnecting them might not even help, as the magnetic field moving across a disconnected transformer might be enough to make it arc across itself, even if it's not connected to anything. My favorite whack job and true believer, G. Gordon Libby, of Watergate fame, wrote an article for Omni magazine back in the 80's that mentions the effects of losing these transformers.

    Nation's Capital and Seven Largest Metropolitan Areas Blacked Out Indefinitely Since the devastating New York City blackout of 1977 much has been done by way of redundancy to protect entire nets from chain-reaction failures. Nevertheless the terrorists exploited a vulnerability brought to governmental attention several administrations ago (and ignored since) by Dr. Robert H. Kupperman of the Center for Strategic and International Studies. The terrorists did their homework very thoroughly. Kupperman's point is as follows: In order to achieve economies of scale, generated electrical power is transmitted over long distances at extremely high voltage (EHV). Think of a power line as a water pipe. In electrical terms, amperage is the flow of water through the pipe. Voltage is the pressure. The higher the pressure, the greater the amount of water a given pipe can transport. To get water under pressure requires a pump. To get electricity under pressure requires a transformer. EHV requires an EHV transformer, both to step the voltage up at the beginning of its journey and down at its destination. There are only about 500 EHV transformers in the entire nation. Their locations are shown on a map available to the public. Most are protected by no more than a chain-link fence and warning signs that serve to confirm exactly what they are. EHV transformers are sophisticated pieces of equipment not manufactured in the United States. The lead time for delivery of a new one from abroad is 18 months. They can be put out of operation by a high-powered rifle. Thus a small number of terroristsâ"a few using .458 Winchester magnum rifles (as was the woman killed by the SEALs), and the rest Israeli-made copies of our Marine Corps' new 40mm lightweight, polymer/ceramic, near-handgunâ"size grenade launchers-took out the few key EHV transformers around Washington, DC, New York City/Newark, Boston, Chicago, Dallas/Fort Worth, Atlanta, Oakland/San Francisco, and Los Angeles. San Diego was saved when an element of SEAL Team 3, on a security penetration test mission, came upon one of the terrorists who panicked and fired on them. After killing her, the SEALs grasped her mission, alerted their superiors, and in short order we had nearly half the few prisoners captured to date. The aftermath of the EHV attack has been devastating. There is no power for the water supply pumps. The effects of arson are impossible to control. Martial law is barely able to maintain order now that the stores are looted and burned. Vigilante justice is rampant. Sanitation has broken down, and the rats are out of control in New York City It

    • Sanitation has broken down, and the rats are out of control in New York City.

      I thought you said this was speculative fiction?

    • This is very badly structured; sorry about that.

      The culprit connected with Watergate was G. Gordon Liddy. He often sparred publicly with G. Gordon Leary, so that may have bought him enough cachet to make it into Omni.

      The only highly notable 'Libby' does sell a lot of beans ... which could lead some to confuse 'him' with Liddy.

    How timely that the American president issued an executive order to prepare for an EMPs in May of this year. Would be too funny if, years down the road, even his detractors had to give him credit for what we were able to save from the electromagnetic apocalypse.
  • OK, so everyone is now officially bored with global warming and we can expect a new wave of 'OMFG the sky is falling' articles.

  • This video tells me that there isn't a whole lot to fear.

    Such storms are rare and the effects when they do hit is something that many have already prepared for. We have detectors to give early warning and measures to address such issues.

  • The non stop push (propaganda?) for getting everyone to switch to electric transportation that gives modern civilization a "single point of failure" infrastructure might possibly be seen as foolhardy.

    I know! Let's push for everything to be electric!! Airplanes, transport and delivery trucks, and everything. You can't store a multi day/week/month supply but don't worry about silly details like that...

We all live in environment-friendly mud huts, eating only wild nuts and berries that we gather by hand each day. We have finally saved the Earth and ensured the long term survival of our species for the future. Yay us for all being miserable! We won!"

  • Having read all of the Maze Runner books, I can appreciate the effect this could have on the population and society. While, it may happen now, in ten years, or in 1000 - it should be something to be concerned about.

    • It makes me think of the Hitchhiker series.
       
      All these silly humans are going on about global climate change when the Earth is scheduled for demolition so the new hyperspatial express route can be built. What are they even going on about?

  • ...this is something that happens unpredictably but generally cynically, so we should be frightened/concerned.

    Yet...paleoclimate studies show a sudden spike of warming/co2 abundance every 120,000-or-so years (last one about 140,000, so we're well past due) and when we see it start to happen again, THIS TIME it's clearly human-caused?
