The plan backfires — and instead of rain, the clouds bring snow, causing global cooling and the beginning of the Ice Age.
In the final scene, the family is gathered together inside their home trying to keep warm.
Realizing that the world is coming to an end, Earl apologizes to his family and admits that he shouldn’t have “taken nature for granted.”
In a touching moment, the Sinclair family accept their fate and promise to stick together (until the end).

To really drive home that this is the end of the Sinclair family, the episode closes with an image of snow piling onto their home while a depressing score plays.
