What sorts of events could cause global industrial civilization to collapse? One of the less likely, but still quite possible, causes is a Coronal Mass Ejection (CME). Basically, this happens when the sun ejects a large amount of superheated plasma. Inevitably, sometimes a CME hurtles through space in the direction of Earth.
This may sound like a nothingburger. But in fact it can be a
civilization killer--when that civilization is so dependent upon electrical
wiring as ours is.
A CME peaking on 1-2 September 1859--before radio or even
voice telephone were invented--caused what is referred to as the Carrington Event.
Electricity danced along telegraph wires, damaging telegraph stations, and even
causing one station to burn down. Such an event occurring today, frying much of
our electronics and electrical systems, could cause up to $7 trillion in
damages just in the US, and even reduce global crop yields by up to half (more
in Central Europe).
For all practical purposes, civilization would end, in an
instant. The resulting chaos would be unthinkable. How many of us could survive
that? How many of us could survive being thrust back into the late 17th
century--without electricity, without the use of electronic or basic electrical
machinery, without power plants to supply our heating and cooling systems,
without motorized agricultural equipment or any kind of mechanized transportation,
without even steam engines--and without the knowledge or skills needed to survive in such a
world?
(For any of you thinking of retreating to the mountains and “living
off the land,” heaven help you if you need any sort of modern medical care.)
How could we avert such a collapse? ***Harden the system.***
The electrical grid throughout the world could be made more safe through the
use of shielding (such as with Faraday cages and the like). Manufacturing
facilities could be placed deep underground in shielded locations to replace
personal goods and other electrical equipment that cannot easily be shielded.
Would this cost a fortune? Of course it would. But that problem is solvable,
too; this, however, is a story for another post.
So, yes, a Coronal Mass Ejection of a certain magnitude would end civilization in a
flash. However, as we shall see, that is not by any means the only scenario
under which civilization could collapse.
All the more reason for focusing effort to Avert Collapse.
