Getting Prepared for an Electromagnetic Pulse Attack or Severe Solar Storm
The science fiction writer Arthur C. Clarke once said:
Any sufficiently advanced technology is indistinguishable from magic.
This statement is commonly known as Clarke's Third Law. Many people have heard this quotation, but few people really think about its implications.
We now live in a world that is so completely immersed in advanced technology that we depend upon it for our very survival. Most of the actions that we depend upon for our everyday activities -- from flipping a switch to make the lights come on to obtaining all of our food supplies at a nearby supermarket -- are things that any individual from a century ago would consider magic.
Very few people in industrialized countries do work that is not directly assisted by electronic computers, although that computerized assistance is often quite invisible to the average person. Few people think about things such as the fact that whenever we buy some food item at a supermarket (and many others are buying the same item), the next time we go to that same supermarket, they still have about the same supplies that they had before. There are invisible infrastructures all around us that are made up of advanced technology. Most of us just take the magic for granted.
Few people stop to consider what would happen if, in an instant, the magic went away. If our advanced technology were suddenly and completely destroyed, how would we manage to survive? A nuclear EMP could make the magic go away. I hope it never happens, and I don't think that it is at all inevitable. It makes no sense, however, to be blind to the danger. It is both much less likely to happen -- and also less likely to have a catastrophic impact -- if, both as a civilization and as individuals, we are prepared for an attack on our advanced technology. A nuclear EMP would be a seemingly magical attack upon our advanced technology, the technological infrastructure upon which our lives depend.
Among all of the kinds of electromagnetic disturbances that can occur, though, it is important to keep things in perspective. It is possible that a nuclear EMP may never happen where you live. On the other hand, a severe solar storm that will destroy most of the world's power grids appears nearly inevitable at this point. Protection against the damage of a severe solar storm could be done easily and rather inexpensively by the electrical utilities; however it is not being done, and there is no sign that it will be done.
