[The Day After Tomorrow] What were the social and cultural ramifications of the events of 2004?

The causes associated with long term ice ages, like decreased solar output or globalized deep water cooling, don't appear to be present.  That means that the climate will likely bounce back in a number of years  or decades rather than millenia.

That won't help the human race in the short term, though.  There will be mass death and starvation, even in the unfrozen global south where food supplies will falter due to the global cooling.  Humanity may be reduced from billions of people to millions.  

The global south and countries along the equator will be overburdened by refugees and their own starving populations.  Crime and insurrection will flourish.  What's left of the human race will either fall into anarchy or draconian rule as governments either fail or impose harsh measures to survive.  The anarchic territories will eventually stabilize in population via survival of the fittest.  The draconian regimes will stabilize in population via mass execution.

By the time the world's climate recovers a new set of governments will have emerged controlling a much smaller human population.  Massive land grabs will happen as the governments compete over anarchic territories and the thawing lands of the northern hemisphere.  The north will be a new lawless frontier, rife with war, imperialism, and banditry.  It will also be a place where people seeking freedom from the authoritarian south will go to establish new homelands.
