"but you'll have a lot more to worry about than EMP if there's a nuclear detonation in the atmosphere. You'll be dealing with fallout and a massive loss of life as well."

I know the scenarios quite well. The initial loss of life really wont be all that much compared to what would be to come. Depending on the distance from the detonation, the fallout wont be an immediate problem either (at least for a few hours), their will be plenty of time to take shelter, though unfortunately there are no shelters unless you are a member of your local nuclear survivors group (they are everywhere, but they try not to make themselves too publically known) or you bothered to construct one yourself. Good news about it is, that when and if this does happen, we wont really be worrying too much about the bees anymore. Not for a while anyway.
