Lyric discussion by darkwolf112 

knowing his history with his ex wife, its likely about the same things as love will tear us apart again,(something they love but is falling)

if on the off chance its not about that, it could be about nuclear weapons, this was released in the height of the anti weapons movement

the real atrocities Buried in the sand Stockpiled safety for a few

Searching for another way See them hide behind the door We'll live in holes and disused shafts Hopes for little more

the ice age could be reffering to the idea of nuclear winter as consequence
