Before 2006, our warm salt subduction mechanism does not allow the Atlantic to cool when its subpolar salinity was increasing, because poleward transport
of warm salty water and increasing subpolar subduction are parts of the same mechanism of enhanced AMOC upper - ocean transport.

The argument is that the increased separation
of the Antarctic land mass from South America led to the creation
of the powerful Antarctic Circumpolar Current which acted as a kind

salty waters from the North Atlantic and Central Pacific from moving southwards towards the Antarctic land mass leading to the isolation
of the Antarctic land mass and lowered temperatures which allowed the ice sheets to form.

Many factors — like the thermohaline circulation, which reverses direction at the poles as
