So global warming will eventually cause an ice age right? That's apropos.

The movie The Day After Tomorrow is quite good, and revolves around this happening.

  It's an absurdly unrealistic depiction of the concept.

    Yes especially that scene when you have a couple of hundred americans trying to cross the Mexican border, when in reality it would be millions.

An ice age in Europe, and maybe colder weather on the US east coast. It will probably also have other effects, but it's really hard to predict.

We are in an ice age right now

Not exactly. We would normally be about to go into an ice age - sometime in the next few thousand years - and actually nothing about the gulf stream slowing is particularly human derived from that perspective. Conceivably global warming could stop it, accelerate it, just be a nuisance term. We simply don't know.

  We're already in an Ice Age, namely the Quaternary. The glaciers have receded somewhat, but the Earth still has a high level of glaciation compared to other geological periods. One of the most important factors is the arrangement of the continents[1]. First, having a large polar continent allows ice to accumulate and increase the Earth's albedo significantly. Second, having two major oceans instead of one decreases the efficiency of heat transfer around the globe, allowing other pockets of glaciation to occur. In a scenario with no polar continents and only one major ocean a glaciation is virtually impossible regardless of where we are in the Milankovitch cycles[2], because the Earth is effectively swimming in a thermodynamic bath. Atmospheric composition is actually a relatively minor factor, it's just that human activity can't shift continents around or affect solar cycles and those both change on much longer timescales than human activity.
