Weather (The Weather's Fine)

The weather caused changes in the timeline of a given location. For example, when the weather was in the 1960, people appeared as they did in the decade of the 1970s, wearing the styles of that era. Technology and infrastructure also harkened back to that decade. A pocket calculator from the 1980s would vanish and be replaced a slide rule in the 1960s.

Old Fronts
It was not unheard of for dramatic changes in the weather to dramatically impact regions or even whole countries. Not long before Tom Crowell rekindled his relationship with Donna, an old front from Canada swept into the upper Midwest, causing several states to revert to the turn of the century. Grainy film-footage from Milwuakee showed people riding in horse-drawn buggies while wearing antiquated fashions. Communications broke down as modern telephones could not connect to telegraphs. In a similar incident, where the weather fell into the 0s, hunger was a major concern.

Year-conditioners
People managed their personal weather by use of year-conditioners. The appliances could be costly, and very often people were content with the sixties and seventies.

Tom Crowell, a citizen of Los Angeles, was able to reunite with his former love, Donna in the 1980s by living in an apartment that was conditioned for the sixties.
