An internal forcing mechanism is a factor in Earth's atmosphere or on Earth that affects the climate. An External Forcing mechanism is a factor that is present, past the atmosphere. (ie. Axis tilt, distance form the Sun, solar storms)

Not sure how to hide this but... 22.1 to 24.5 over a 41000 year cycle called obliquity and is a factor if the milankovitch cycles.

What drives thermohaline circulation and how does the water return to the equator?

It's driven by differences in density due to different water temperatures and salinities in ocean water, forming a large global "conveyor belt." It goes to the equator because the density is higher at the poles and salinity is slightly lower at the equator than its surroundings.
