10 Doomsday scenarios

[Scythe13]

For the Economic Collapse, I'd be careful in assuming it will lead directly to civil unrest. The Unrest could well be from some other event. Although NR is joking, he does so with a hint of truth. It could be a menial thing that we all see as the last straw. However, civil unrest could be the same as what happened over in Syria. I think Civil Unrest could lead to Civil War. Along with Civil Unrest, I'd like to include a Revolution. It really wouldn't take much to get the grunts of society to kick up a HUGE fuss!!! Then someone gets killed. After that....more on the streets....and the fun begins.

But that's a pretty good list.

Polar Shift is another possibility, along with Mini (or Mega) ice age. But they may be covered in the weather part.

What about fuel/power/food shortages? It wouldn't take much to screw up the crops for the earth. Same as the power grid, or fuel system.
