Two years ago, an intense solar storm narrowly missed Earth. If it had hit, researchers say, we could still be picking up the pieces.
I just realize that we narrowly escaped 2012!
So a solar flare that wipes out the globe's electrical system will cost only $2 trillion (or about 5% of global GDP), and the big problems will be GPS and cell phone coverage? What about refrigeration and the ability to cook? How about the ability to process electronic payments (how much cash do you have on hand)? Such a storm wouldn't knock us back to 2002, it'd knock us back to 1800, but without the widespread knowledge of how to live with that level of technology.
_"...but without the widespread knowledge of how to live with that level of technology"_
You hit the nail on the head. In addition to the difficulties you mention, the transportation system could collapse on a large scale, causing food to run out in (darkened) cites within days. Afterword, how would our industrialized, agrochemical-dependent food system produce enough food, and get it to people in those cities? Not to mention how water would be supplied if there wasn't sufficient electricity.
I have earlier posts here that may interest you.
+nine9s Study science please.
We need to realize how vulnerable we are. Good video
Yep, wouldn't it be great if we were spending some money on things like beefing up the energy grid to withstand solar flares, and asteroid deflection programs instead of wasting it on weapons :)
On the plus side the aurora will be amazing, but you would need an old film camera to photograph it :-)
It's videos like these that are the Sol reason I'm subscribed... :)
I see what you did there :)
We must harden our grid, it would only cost a few billion. Sad that it took nasa 2 years to put this video together and realize this. In the mean time we are a sitting duck...
Are we not taking any precautions for this? This issue should be more on the forefront than climate change. Surely precautions can be put in place in time before aware hit again that will make it easier to re establish what was destroyed
Maybe we should consider shielding sensitive and expensive devices such as transformers from solar storms. We could survive without GPS or internet but the power grid should at least be protected.
You cannot "shield" them, you have to disconnect the from long lines, because those collect the energy from the warped magnetic field of the earth. A battery radio running when the CME hits will just give a lot of static and continue to work.
I'm a farmer and I can see a major threat to your food supply if we get hit by a natural or man-made EMP! Most of our farm tractors and vehicles are loaded with computer chips that would be fried making them useless instantly
And as far as the transportation of food from farms to your cities how is that going to happen as most of the shipping in this country is done by semi trucks that are also full of computer chips and would most likely be nonfunctioning to cities would quickly become death traps
Cities don't last very long without electricity and after and you were looking yet but you're too without electricity dollars if we last that long
The United States needs to take precautions if only we had the cash and not a broke nation
sillydog70 convert to distributor-points ignition that technology will still work after an event like this.
So What can be done to be "prepared.". If all electric was shut down would there still be a massive damage?
LOL so December 21 2012 came earlier than expected.
Actually, ridiculous predictions of extraordinary Solar flares for that date are one of the reasons why debunkers wouldn't listen to real concerns, like the ones described in this video
This would not be like a regional disaster like an earthquake or hurricane. In a national scale catastrophe neither the federal nor state governments will be able to help you and your town for months or longer. Survival will be a local issue. The cavalry will not be coming.
In fact, in August of 2012 a bi-partisan group of lawmakers advocated that communities establish a civil defense program in case of such a grid-down scenario, but Congress failed to act.
Makes you realize how bullet proof that probe is.
We must harden our grid, it would only cost a few billion. Sad that it took nasa 2 years to put this video together and realize this. In the mean time we are a sitting duck...
It concerns me that this has never been properly reported. People continue to be unaware of how vulnerable our electrical grid and our society is to these kinds of solar events that happen regularly every century or two. Just imagine for a moment no electricity for months or years. Few of us would survive, or know how to survive. It shows again how completely wrong-headed and misdirected our politics are that we continue to spend billions, trillions, fighting each other instead of dealing with real overarching threats to our species.
In the beginning of the video, it hit Stereo A then why is Stereo A still active. We're not "picking up the pieces" of Stereo A? I'd assume Stereo A is much more fragile then planet Earth? I mean are we making these CME a exaggeration on what could happen or do we really not know?
and earth isn't?
The power grid is totally unprepared for a solar flare of this intensity. If a solar flare like this hits it will take years and even decades to restore the power supply. The planet itself will just brush this off, but the most likely outcome for us is a total social and economic collapse.
I believe it's been permanently damaged in some way, but still gets the job done. Let's also not forget the stress that these large earth-facing CME's would put on the tectonic plates. you're talking power grid, communications failure and severe land damage from quakes. That's when Marshall Law kicks in folks and FEMA takes over. They are preparing for these possibilities
alienrefugee51
What? It has absolutely no effect on the tectonic plates. It creates a strong magnetic field which inducts electricity in the wires. This strong power surge is what takes out the grid. That's it. Earth will be just fine, our power grid is screwed.
OK, explanation time.
Electricity is generated simply by passing a magnetic field over a wire. A hydro power plant for example is simply water turning a giant magnet inside a coil of wire. Now when a large CME hits the earths magnetic field it causes the magnetic field to quickly shift, or vibrate. When this happens the magnetic field acts like the magnet in the power plant, and the entire electrical grid act like the coil of wire except on a global scale. The shifting field can quickly energize the power gird well above it's designed threshold. This gigantic amount of power energy pumped into the entire grid at once would have catastrophic effects, such as the massive transformers at power stations all blowing up at once or thousands of miles of power lines simply burning out. And of course it would destroy almost anything plugged into the grid as well.
And this is not just a hypothesis. We KNOW it could (WILL) happen because it's happened before as recently as 1989!
Look up the 1989 Quebec power failure.
To say that it would be bad is an understatement.
I absolutely agree that a large CME could seriously harm our electrical systems. Nonetheless, I chose to have no fear of the sun. To me, fearing the sun is as silly as fearing a loving God. It is even possible that a temporary interruption in worldwide electronics would be a good thing for us as a species. If you're truly worried about a power-grid outage, I recommend that you make certain that you have easy access to a significant supply of water (by stockpiling water barrels or living near a lake or river), own a gravity-powered water filtration system, and invest in some storable food.
If I were to put a pizza pop on the roof when one of these CME's hit, would it be done just right?
If such an event hit Earth today, I'll venture it might actually improve society.
Please someone say our nuclear power plants are protected from a large CME? Imagine every nuclear plant on earth melting down all at once. Not having power would would be the least of our problems.
_"Please someone say our nuclear power plants are protected from a large CME?"_
The risk that CMEs present to nuclear plants is not so much from the CMEs themselves, as from the potential for collapsing the electrical grid.
Contrary to a common belief (even among technical people who should know better), the electricity that powers a nuclear plant's safety systems comes from the grid, rather from the plant's own generators. That's sound thinking, by the way: the grid should be a more-reliable source of emergency power than the generators of the plant that's experiencing the emergency.
Collapse of the grid would be what the NRC calls a *Loss of Offsite Power* (LOOP) Event. To deal with such an event, plants have (among other possibilities) diesel-powered backup generators to pump water for cooling the reactors and spent-fuel ponds.
The questions that arise related to nuclear plants and CMEs are (1) how long must the backups run (reactor designs vary in their requirements for safe shutdown, and many old reactors are still in service); (2) how much fuel for the backup generators will be on hand when the grid fails; and (3) if need be, can the backups be refueled during the social chaos that would follow collapse of the grid?
I don't know the answers to the above, but I do recognize the potential danger.
Why are we still measuring the solar cycle based on only half the sun, i.e. the side facing toward us ? I noticed during this cycle a lot of activity was on the side of the sun facing away from earth (including this superstorm). We have a 360 degrees view of the sun now, so doesn't it make sense we should take the whole of the sun into account now ?
how did we only hear about this 2 years after it happened x]
You got a shitload of celebrity "news" instead :) Are you not entertained?
This is fascinating and alarming at the same time. Because a CME can hit earth at any given time, right now there arent many sunspots, only 2121 which has low class flares. Even though probably at a moments notice it could spark a x-class flare and then... shit just got real. We know very little of solar activity and it's cycle, we've (modern man) been around for 50,000 years. And much less recorded history. In the scope of a galaxy year, how would it affect space weather in terms of solar activity.
A Carrington-like event will happen, that's a certainty, whether it's tomorrow or 200 years from now. We're so unprepared that's it's scary.
barrel Ovens would allow entire communities to have a way of cooking food and purifying water
Amazon.com has a great book on building barrel Ovens look it up
The Amish are EMP proof LOL
But who wants to be Amish
I prefer to be somewhere in the middle with a "rocket mass heater" and a "barrel ovens "
Congress needs to legislate a fix to the grid that will safeguard it.
Just a technical point. Very interesting video, but I see that some of the captions (e.g. at 2:13) don't fit into the screen at the regular font size, To avoid this, they should be split up into smaller pieces (which can be done by editing the captions, no need to post a new video).
Very interesting I wonder when the next one will occur? Hopefully when earth is not in its path!
It missed the Earth by NINE days...that's not a narrow miss!
nothing can prepair what.comes ,comes ,
what would actually *REALLY* happen?
or we can't know for sure?
No electricity for years. No fresh food delivery to your neighborhood store when the refrigerators stop working. Hospital equipment doesn't work. Water supply stops - no electricity, no water pumps stations. Basically total social and economic collapse :(
The value of having space weather bouy's all around the sun, in a modern society dependent on electronic communication. We could get an other big solar storm like the one in 1859 that wiped out the long distance electronic communication of it's day.
***** How can this be tested? Artificially i mean!
test what?
A weak cycle can also mean that the pressure is building up, instead of being released. Think of a pot of boiling water with the lid closed. Possibly blowing up big scale at a later stage.
Lord Zephyros how it would affect Earth if it hit us full on!.
Stargazer Nation
Toss your electronics onto a giant magnetic field. It's a crude way to test it but simple!
Stargazer Nation All those electronic devices (including computers) we all like so much? Throw them all away. The factories that make them (largely depend on computers themselves) wouldn't be producing any more for some time. We'd be lucky if the lights turned on.
Stop and consider how depending we are on working computers and networks today. Even 20 years ago our dependence was much less. Want to see a real economic depression? A Carrington event today would cause one. Recovery would be slow. After this we would build gear that would survive events like this better. We know how to do this but it makes the equipment a lot more expensive and can make them heavier. As the decades passed the memory would fade and we'd go back to business as usual - until the next event.
The black circle given by the sun telescope saved my eye from impact of solar storm.
This is what scares me about the future and full automation.
If we didn't blow a ton of money on stupid projects, then we could have been able to fund this with no problem.
is this 3 days darkness true??? with the solar storm?
No.
Maybe The CME is the reason of earth quakes... can we try this theory...
Im scared
is this had hit us,all the 2012 doomsayers would have said 'Told ya so'
if it happens at night time it will be ok
Only where you are... other side fried so that's OK?
We'd have known about it from its effects.Wouldn't need space" whatevers" to tell us.
Thank you.
Tahiti is in the southern hemisphere so he should have said as far north as Tahiti as it was most likely the Aurora Australis.
Fuck!! I wanted a restart!!!
If,maybe, could ,nearly but didnt ,pointless.
How do I protect my computer???
so we already can't remember how we used to live without computers...
but since then there were no actual relevant solar storms
and if it hits us now, we're totally unprepared
and we'll remember a little bit how we used to live without computers?
When people lived that way the population of earth was just 1 billion, now it's more than 7 billion, there's no way to revert to the old way of life without massive social consequences like several billion people dying from starvation, thirst or disease. Computers are not the issue here, electricity is. Every aspect of your life depends on it - food, water, hospitals etc... If we don't prepare our energy grid for Solar Storms then sooner or later we'll be totally screwed!
holy shit we were so fucking lucky !!
What exactly does the solar cycle indicate?
Fake. Stars does not Exist.
Can it be provision and controled?
I'm positive that half the population of earth would perish due to the internet and face book being nonexistent in the event of a direct hit from one of these. And all those poor souls being lost forever without G.P.S. Oh the humanity!
SCIENCEATNASA.
GRACIAS DRAGON SITO
guys this will happen when god sends it to earth to destroy earth and recreate earth
What "interplanetary medium" is supposed to slow a CME down? Are you sure you don't mean the interplanetary, intergalactic electromagnetic field we live in? LOL!!! If you don't know what I'm ranting about, see the video How to Watch the Sun. More double-talk from Never A Straight Answer, tsk, tsk...
Whoa!
Assassin's Creed is real :O
Geee, thanks for the warning...2 years late!
There's a good chance we wouldn't have heard anything from the media back then considering it would've knocked out most modern communication and that little thing called the power grid. You know! The small stuff.
Nice!!!
More than a Rick Perry "Oops"!
;]
Listening to the reports from the sun...God has issues too huh?
