Does that help?
1) time loop, complete destruction of the earth at end
2) complete destruction of the earth, scavengers in space collecting the detritus for Mars colony
3) earth wakes up, tells the human population she's leaving for a snazzy retirement home in some far off galaxy
4) impending complete destruction of the earth (and sun), earth set up to try to survive the supernova of sun, but effort sabotaged, survivors in ships going to some far off galaxy
5) wind, wind everywhere, eat other people
6) bacteria and viruses wiped out, earth ecosystems drastically altered, there are survivors, but survival is suspect
