Fantastic. It makes me glad that I kept a couple of Nikon F3's around
that can be used without electronics so that I can get pictures of the
end of the world--so long as the bodies don't melt, that is.
I'm sure that S&T and the various photography forums will have useful
hints on photographing the end of the world.
Barman: Do you really think the world's goin' to end?
Ford: Yes.
Barman: Shouldn't we lie down or put a paper bag over our 'eads or
something?
Ford: Um, if you like.
Barman: Will it help?
Ford: Not at all.
Barman: Last orders, then!

I can see trouble for satellites and short-wave communications.
I suppose that home computers could be damaged if the power goes out
in a spiky fashion - and it _has_ happened that space weather has led
to power failures in areas served by hydroelectricity transported over
long distances. Thus, computer users in Montreal and New York might
want to exercise caution.
But even if somehow a giant CME fries all our iPods, it's hardly the
end of the world, even if they _did_ cost good money. Unless first the
electronic toys are destroyed, and _then_ we all go insane and die of
boredom.

It's nonsense to suggest that solar activity is going to damage small
electronic devices. However, if we actually had solar activity strong
enough to fry iPods, that would be the end of civilization, if not the
world. That kind of energy would essentially destroy all electronics,
everywhere on Earth. Civilization would not survive that.

It's like the nuclear annihilation scenario. Even if we survived, life
wouldn't be worth living without iPads, iPhones, and iPods.
The Chinese should do well in such a scenario; they're the ones that
would manufacture all the replacements.
I gotta update my cosmic catastrophe insurance. Does the AppleCare
extended warranty cover that?
Civilisation might not, but some humans probably would at least those
who were inside steel framed buildings at the time. Losing bank machines
and mobile phones would be much more of a problem. The Torygraph are
certainly hamming up the mad max / apocalypse now angle.
I suspect about the worst case would be GPS satellites damaged and
degraded and a loss of satellite live feed bandwidth. Anything that was
sealed inside something as unsophisticated an earthed biscuit tin would
survive serious levels of EMP so if you want your iPod to survive that
is where to put it.
Power grid at very northern latitudes could be knocked out - although
the power companies might chose to shut down and isolate key components
ahead of any incoming CME front hitting.
It is a relatively high risk low probability event and the satellite
monitoring should show any inbound CME in plenty of time for sensitive
systems to be shut down. I seriously doubt if Europes electricity grid
is all that vulnerable either. The magnetic pole is just north of
Canada. It is *extremely* rare to see aurora in the UK at latitude 51N.
Is somewhat more balanced in its reporting although it does detail the
so called Carrington flare of 1859 which would probably do a lot of
damage to long transmission lines and communication satellites today.
The aurora would be pretty impressive though.
If it has enough ooumph to key big grid distribution transformers then
it could take a while to recover power in affected zones. They are
usually made to order...

Unless, of course, the solar storm was long lived enough to "bake" the
whole globe.
I've spent my whole life being told to be afraid of the latest scare.
Didn't affect me at all.
Didn't affect me at all.
Didn't affect me at all. ;-)

How much of that was due to faulty electrical design and the electrically
wrong use of the grounding conductor as an electrical path?
Canada lost their grid because they failed to equalize the potential of their
system to ground.

EMP-proof boxes - a new line in iPod accessories!

Could take years, and you might not be able to flush your john:

Maudlin stuff. Too many adjectives. And, unlike those ants, we have no
super-being(s) looking down on us and deciding whether we prosper or
perish.
Furthermore, if it's any consolation, remember that the ants outnumber
us and by just about any rational measure are a far more successful
species than we are, unencumbered by sentience and the woes that are
troubling you.
Instead of mourning the few ants that get cooked by thoughtless little
boys, lets celebrate the uncountable myriad that live their lives in
relative peace and oblivion.

And if we aren't sent into a new dark age by all our computers being
fried in 2013... in 2015, the New Horizons mission will make its
closest approach to Pluto.
At which time, we will discover it is the home of the Mi-Go, and,
therefore, "retreat to the safety of a new dark age".

"Ants are the most warlike of all animals. War is something that can
only originate when you have societies. You know, you can say that one
snake was at war with another one in the swamp. But we mean it to be
of group against group. And ants actually are a lot more violent and
warlike than human beings." --E.O. Wilson, author of "Anthill"
