Are JWs seeing signs of the end now?
There are many "signs of the end". It could be hurricanes, tornados, earthquakes, increase of hemorrhoids, increase of apostates, wars, jaywalkers, or whatever. I've heard all of these things referred to as a "sign of the times". A JW will use just about anything to reinforce his belief, no matter how ridiculous.
I'm sure there were earthquakes and weather disturbances before the appearance of humans on the earth. Were they some kind of sign too? No!
JWs don't seem to be able to accept natural occurrences for what they are - natural.
There was an earthquaqe 200+ years ago in china that killed 600k people!
