As Ultra Woman said, I'm thinking that Nightfall is the. Natural disaster he is there to head off. I'm thinking that is also the event that screwed up the timeline by killing Tempus' ancestor and once Alt Superman stops Nightfall the timeline can then be restored.
Actually, we learn in "Another Lois" they somehow survived Nightfall without Superman. I am not sure if I should tell how that occured, but it did.
The Disasters that Superman is needed to prevent seem to have been Larry Smiley's new flood of the earth/Bob Fences death-ray. Well, the body count was pretty bad before that, what with the colonist shuttle exploding and other stuff, but it is only when those two combined hit the earth that anything like most of the population dies.
