I have some very vague memories about a TV series (I think) that I used to watch as a kid back in the earlylate 90s/early 2000s (1995I'd say around 1995-2003). I don't really remember anything about it; the only important detail remaining in my memory is that the characters were making a big fuss over some incoming disaster, basically an end of the entire world. It was, however, stated very strongly that if they would meet some certain conditions, not all of the would would meet its doom, but "only" a northern part (a hemisphere perhaps...?) of it would cease to exist (or perhaps other way around, be spared). I guess preventing the disaster entirely was impossible and saving a part of it was already considered a success.
This was probably a series aimed for kids or young adults, because I doubt my parents would let me watch any serious stuff back then.
I know this isn't much. Does anybody remember something like this...?
