No offense, but there's no way for a person reading what you wrote to even know whether you're speaking literally or figuratively.

Are you referring to climactic events, societal/governmental upheavals, or ???

Do you have access to some sort of government top secret information that's being purposefully withheld from the general public? Personal knowledge currently known only to yourself acquired through personal research? A time machine?

And I'm being serious too, but you have to admit that it's somewhat difficult to prepare for something when you don't know what you're preparing for.

Just trying to be as helpful as you are apparently trying to be, but all I can say is, short of supplying information that can actually be put to use by those you are trying to help, all I can suggest is that you prepare for possible replies of the Chicken-Little variety.
